Rekeying Between Tenants: Calgary Landlords

Tenant Turnover: When Calgary Landlords Should Rekey

Rekey between every tenancy, after the outgoing tenant has returned possession and before the new tenant moves in. In Calgary this costs roughly $20 to $60 per cylinder plus a service call, which makes it one of the cheapest line items in a turnover and the only reliable way to guarantee that no former tenant, their ex-partner, their friend, or a contractor still holds a working key.

The legal timing matters as much as the decision itself. Under section 24 of Alberta's Residential Tenancies Act, a landlord cannot change locks during a tenancy without immediately providing the tenant a key, and cannot change locks at all until the tenant has given up possession, abandoned the premises, or been evicted under an Order for Possession. Getting that sequence wrong turns a $60 rekey into an offence.

This guide covers what Alberta law actually permits, when you can and cannot change locks, what rekeying costs per unit and across a portfolio, when you can charge the tenant for it, and how key control changes once you own more than a couple of doors.

This article is general information for Alberta landlords, not legal advice. Verify anything decision-critical against the Residential Tenancies Act itself or with Service Alberta.

Should You Rekey Between Every Tenant?

Yes. Rekey every unit between every tenancy, without exception, as a standing policy rather than a judgment call. Returned keys prove nothing, because you have no way to know how many copies were cut during the tenancy. A rekey costs $20 to $60 per cylinder and removes the entire question.

The core problem is that you cannot audit copies. During a one-year tenancy, a standard Weiser or Kwikset key can be duplicated at any hardware store, Canadian Tire, or key kiosk in Calgary for about $3, in ninety seconds, with no record and no authorization. A tenant hands back two keys at move-out. There is no way to know whether two were ever cut, or seven.

Consider everyone who plausibly held a key during a single tenancy: the tenant, their partner, a roommate, an ex-partner who left mid-lease, adult children, a friend who watered plants, a dog walker, a cleaner, a subletter, and any contractor the tenant let in. Most of those people are entirely trustworthy. That is not the point. The point is that you cannot produce a list, and your obligation to the incoming tenant is that their door is secure.

There is also a liability dimension. If an incoming tenant suffers a break-in with no sign of forced entry, and it emerges that you never rekeyed after the last occupant, you are in a materially worse position than a landlord with an invoice showing the unit was rekeyed on turnover. The invoice is cheap insurance. Treat it as part of the turnover cost structure alongside cleaning and paint, not as an optional extra.

The economics are lopsided in the extreme. A rekey on a two-door unit runs well under $200 including the trip. A single break-in claim, an insurance deductible, a tenant dispute, or one vacancy caused by a security complaint costs many multiples of that.

What Does Alberta Law Actually Say About Changing Locks?

Section 24 of Alberta's Residential Tenancies Act governs locks and security devices. Neither landlord nor tenant may add to or change the locks on doors to the residential premises without the other party's agreement, which can be verbal or written. The exception that matters: a landlord may change locks without agreement provided a key is given to the tenant as soon as the change is made.

The statutory framework, with the sections a Calgary landlord actually needs:

• Section 24, locks and security devices. The central provision. Governs who may change locks and under what conditions.
• Section 23, entry of premises. Requires 24 hours written notice, with entry between 8 a.m. and 8 p.m., except in genuine emergencies. You cannot let a locksmith into an occupied unit without satisfying this.
• Section 16, landlord's covenants. Your baseline obligations to the tenant.
• Section 31, abandoned goods. Applies once you have determined a unit is abandoned.
• Section 34, order for recovery of possession, and section 34.1, requirements respecting eviction. These control the eviction sequence.
• Section 60, offences. Lists which contraventions are chargeable offences and the maximum fines, which run to $5,000 or $10,000 depending on the offence.

Your key obligations at the start of a tenancy are broader than most landlords realize. You must provide the tenant a key for the residential premises, the main doors, the mailbox, and any common areas the tenant has a right to access, such as recreational or laundry rooms. The mailbox is a genuine and frequently missed one. Mail theft is a real problem in Calgary, and a mailbox lock that has never been changed across multiple tenancies is a live exposure. Our mailbox lock replacement service covers that side of a turnover.

The reciprocal rule is that the tenant must return all keys at the end of the tenancy, including any extra keys they had cut at their own expense. Tenants are also responsible for damage or disturbance caused by anyone who used the tenant's keys to enter.

One asymmetry worth knowing: a tenant who changes the locks without providing you a key has committed an offence under the RTA, with a maximum fine of $5,000. Only Service Alberta can charge someone with an offence, and there is a three-year limitation period on proceedings. Your practical remedy is a written complaint to Service Alberta, or the RTDRS for a civil dispute, not self-help.

When Can You Not Change the Locks?

You cannot change the locks while a tenant still has possession, even if the tenancy has legally ended, even if rent is owed, and even if you have served notice. The lock change is only lawful once the tenant has given up possession, abandoned the premises, or been physically evicted under an Order for Possession enforced by a civil enforcement agency.

This is the single most expensive mistake a Calgary landlord can make, so the sequence is worth stating plainly:

A tenancy that has ended does not equal possession returned. If the tenancy expires and the tenant has not moved out, they become an overholding tenant. You cannot change the locks to keep them out. You must apply to the Alberta Court of Justice or the Residential Tenancy Dispute Resolution Service for an Order for Possession.

An Order for Possession is not self-executing. If the tenant still will not leave after the order, only a civil enforcement agency has authority to evict, and only in accordance with that order. The locks cannot be changed until the tenant is actually evicted from the premises.

Non-payment of rent does not authorize a lock change. Neither does a substantial breach, a nuisance complaint, or damage. Every one of those has a defined process under the RTA. None of them is a lock change.

Self-help eviction is an offence, not a shortcut. Changing locks, removing belongings, or shutting off utilities to force a tenant out exposes you to a chargeable offence, an RTDRS order restoring the tenant's access, and liability for their alternate housing, moving, and storage costs. A locked-out tenant can also involve police, since depending on the facts it may be both a civil and a criminal matter.

Abandonment is different, and it is a determination you must actually make. If you determine the tenant has abandoned the premises, you may change the locks to secure the unit and the tenant's belongings, if any. Section 31 then governs how you handle abandoned goods. Abandonment is a genuine legal determination based on evidence, not an assumption you make because someone missed a rent payment and is not answering their phone.

Mid-tenancy lock changes require an immediate key. If you have a legitimate reason to change a lock during a tenancy, a broken cylinder, a lost key, a security concern, you may do it without the tenant's agreement, but you must put a key in their hand as soon as the change is made. Failing to do so is an offence. Any non-emergency locksmith visit to an occupied unit also needs 24 hours written notice under section 23.

Any locksmith who agrees to change locks on an occupied unit so you can keep a tenant out is not doing you a favour. They are helping you commit an offence and leaving you holding the liability. A legitimate operator will ask whether the tenant has given up possession before touching the door.

Can You Charge the Tenant for the Lock Change?

Yes, in one specific circumstance. If the tenant fails to return the keys at the end of the tenancy, the landlord may change the lock and charge the tenant for the cost of the change. This is set out directly in the RTA framework and is one of the few clean cost-recovery mechanisms available to Alberta landlords.

What makes this work in practice:

• Document the keys at move-in. Record exactly how many keys were issued and for what, unit door, building fob, mailbox, storage, laundry, on the move-in inspection report. Move-in and move-out inspection reports are mandatory under the RTA, so this is documentation you are already required to produce.
• Record the return at move-out. Note on the move-out inspection report exactly which keys came back and which did not.
• Keep the invoice. A dated locksmith invoice tied to the specific unit is what turns a claim into a recoverable amount.
• Understand the limits. This provision covers unreturned keys. It does not convert your standing turnover rekey into a tenant charge. A routine rekey between tenancies where all keys were returned is your operating cost, not theirs.
• The security deposit is governed separately. Deposits are capped at one month's rent, must sit in an interest-bearing trust account within two banking days of receipt, and deductions depend on the inspection reports being properly completed. A deduction with no supporting documentation is how landlords lose at the RTDRS.

The practical takeaway is that documentation is what makes this provision usable. A landlord with issued-key counts on the move-in report, returned-key counts on the move-out report, and a locksmith invoice has a straightforward claim. A landlord relying on memory has an argument.

Rekey or Replace? Which Makes Sense for a Rental?

Rekey. For rental turnover, rekeying is almost always the correct choice, because the hardware is usually fine and only the keying needs to change. Rekeying runs $20 to $60 per cylinder against $100 to $250 per lock for replacement, and it is faster, which matters when you are trying to close a vacancy gap.

Rekeying changes the pins inside the existing cylinder so old keys stop working. The hardware stays, the finish stays, and the tenant-facing experience is identical. Replacement means new hardware entirely.

Rekey when: the existing locks work smoothly, the hardware is decent quality, you want all doors on one key, and you simply need the old keys dead. This describes the overwhelming majority of turnovers.

Replace when:

• The lock is worn, sticky, or requires jiggling. A tenant who has to fight the door will call you about it, and eventually a key will snap in it.
• It is bottom-tier builder hardware on a unit you intend to hold long term. Grade 3 residential hardware is the minimum standard and it does not survive repeated tenancy cycles well.
• There is any sign of tampering, prior forced entry, or damage.
• You are standardizing a portfolio and want consistent hardware you can stock parts for.
• The unit turns over frequently and you want to move to a keypad or smart lock to eliminate key handling entirely.

A useful middle path for portfolios: replace with better cylinders once, then rekey those cylinders on every subsequent turnover for a decade. You pay for quality hardware a single time and every turn after that is a cheap rekey on a lock that actually holds up. Our guide on rekeying versus replacing locks covers the decision framework in more depth.

Do not overlook the interior-to-garage door in a house or townhouse rental. It is the most-used and least-maintained lock in the property, and it is a common gap in turnover rekeys.

What Does Rekeying Cost a Calgary Landlord?

Rekeying costs $20 to $60 per cylinder in Calgary, plus a service call of roughly $25 to $75. A typical single-family or townhouse rental with a front deadbolt, a front knob, a back door, and a garage entry runs roughly $150 to $300 all in. A one-bedroom apartment with a single door and a mailbox often lands under $150.

Typical ranges:

• Per cylinder rekey: roughly $20 to $60.
• Service call or trip fee: roughly $25 to $75, usually charged once per visit regardless of door count.
• Single apartment unit, one door plus mailbox: roughly $90 to $180.
• Townhouse or house, three to four cylinders keyed alike: roughly $150 to $300.
• Mailbox lock replacement: roughly $50 to $120.
• Deadbolt replacement, if the hardware is failing: roughly $100 to $250 installed.
• Restricted or high-security cylinder: roughly $80 to $200 per cylinder, considerably more than standard.
• Master key system design and setup, multi-unit: widely variable, often $150 to well over $1,000 depending on door count and hierarchy.
• After-hours premium: roughly $50 to $150, and worth avoiding by scheduling turnovers in advance.

The single biggest lever on your per-unit cost is batching. The trip fee is charged per visit, not per door. A landlord who calls a locksmith for one unit pays the trip fee on one unit. A landlord who schedules four turnovers in the same building on the same morning spreads one trip fee across four units and gets a materially better per-unit number. Anyone managing a building should be thinking in scheduled batches rather than reactive one-offs.

Keying alike is usually free or close to it, and it is worth asking for explicitly. Getting a unit's deadbolt, knob, and garage entry on a single key means one key per tenant instead of three, which reduces lost-key calls and simplifies your move-out count.

Do You Need a Master Key System?

If you own more than about four units in one building, yes. A master key system lets one key open every unit while each tenant's key opens only their own door. Without it, a landlord or property manager carries a ring of individually cut keys and hopes the labels are right, which fails predictably during an emergency.

How the hierarchy works in a rental context:

• Grand master or master key. Held by the owner or property manager. Opens every unit and common area in the building.
• Sub-master keys. Open a defined group, useful when you want a caretaker to access mechanical rooms and common areas but not suites, or a maintenance contractor to reach one floor.
• Change keys. The individual tenant key. Opens that suite and nothing else.

The operational benefit is that on turnover you rekey the change key side of a unit without disturbing the master. Your master key still works, the outgoing tenant's key does not, and the incoming tenant gets a fresh key. That is a fast, cheap, repeatable operation rather than a project.

Three cautions worth stating honestly. First, a master key system concentrates risk: if your master key goes missing, you have a building-wide problem, not a unit problem, and re-establishing the system is expensive. Master keys need genuine custody discipline. Second, a master system does not suspend the RTA. Holding a master key does not entitle you to enter a unit, and section 23's 24-hour written notice requirement applies regardless of which key is in your hand. Third, the system has to be designed around how your building actually operates, which means someone mapping your doors, your staff, your contractors, and your common areas before any cylinders get pinned.

Multi-unit buildings also carry hardware that sits outside residential locksmithing entirely: main entry doors, fob and access-control systems, panic hardware on stairwells and exits, door closers, and mail room banks. That is commercial locksmith territory, and it is usually the same visit.

How Do You Stop Tenants From Copying Keys?

Use restricted or patented keyways. A standard Weiser or Kwikset key can be copied for about $3 at any hardware store in Calgary with no authorization and no record. A restricted keyway uses a patented blank that only an authorized locksmith can obtain and cut, so keys are only made when you say so, and every one is documented.

This is the mechanism that actually solves the copying problem rather than managing around it. The tradeoffs are real and worth being straight about:

What you gain. Genuine key control. Keys cannot be duplicated at a kiosk. You get a documented record of every key cut for every unit. On turnover, you know precisely how many keys exist because there is a paper trail. Restricted cylinders are also typically higher grade and more pick and drill resistant than the builder hardware they replace, which is a security upgrade on its own.

What it costs. Restricted cylinders run roughly $80 to $200 per cylinder against $20 to $60 for a standard rekey, and additional keys cost more than $3 each. This is a real capital decision, not a minor upgrade.

Where it pays. Multi-unit buildings, higher-rent inventory, furnished units, buildings where you have already had a key control incident, and any property where a break-in with no forced entry would be catastrophic. The math works when you amortize the cylinder over many tenancies rather than charging it to one.

Where it does not. A single low-rent unit that turns over rarely. A standard rekey between tenants achieves the security outcome for a fraction of the cost.

The realistic middle ground. Restricted keyways on building main entries, common areas, and mechanical rooms, where a copied key is a building-wide problem, and standard cylinders inside individual suites, rekeyed each turnover. This puts the control where the exposure concentrates without repinning your entire portfolio.

Are Smart Locks Worth It for Calgary Rentals?

For high-turnover units, often yes. A keypad or smart lock eliminates physical key handoff entirely, which removes lost-key calls, unreturned-key disputes, and the trip to hand over keys at move-in. You issue a code, you change it at turnover, and the old code is dead instantly at no marginal cost.

The genuine advantages for a landlord:

• Turnover becomes a two-minute software task rather than a locksmith appointment. Delete the old code, issue a new one.
• Contractor and showing access on a schedule. Give a code that works Tuesday 9 to 5 and expires. No key to retrieve.
• Audit trails on better models. You can see who entered and when, which resolves disputes.
• No unreturned keys. The entire category of problem disappears.
• Faster vacancy fills. Self-guided showings become practical.

The honest drawbacks, particularly in Calgary:

• Batteries die in the cold, and they die faster than you expect. A keypad on an exterior door in a Calgary January is running on batteries operating well below their rated conditions. This is the number one smart lock failure mode here, and it produces exactly the 11 p.m. lockout call you were trying to avoid. Replace batteries on a fall schedule, not on failure.
• A dead keypad is a lockout, and a lockout during a tenancy is your problem. The RTA does not care that the battery died.
• Cost. Roughly $200 to $500 per door installed, against a $60 rekey.
• Tenant-installed smart locks are a section 24 issue. A tenant who installs one without your agreement and does not give you access has committed an offence. Address this in the lease before it happens.
• Keep the mechanical override. Most smart locks retain a key cylinder. Keep it, rekey it on turnover, and make sure someone knows where that key is.

The sensible read: smart locks earn their keep on furnished units, short-term or frequently turning inventory, and buildings where you are already managing scheduled contractor access. For a stable long-term single-family rental, a $60 rekey every two or three years is hard to beat on economics.

What About Condos and Secondary Suites?

If you rent out a condo, you control your suite door and nothing else. The building's main entry, fobs, mail room, parkade, and common area locks belong to the condominium corporation, and a locksmith cannot rekey any of it without the corporation or property manager's authorization. Rekey your suite on turnover and handle building access through the corporation.

The practical divisions:

Rented condos. Your suite lock is yours to rekey freely between tenancies, and you should. Building fobs are programmed by the condo corporation, so a departing tenant's fob has to be deactivated through them, not by you or your locksmith. That is a step landlords miss constantly, and it means an ex-tenant can still walk into the lobby and the parkade long after their suite key is dead. Add fob deactivation to your move-out checklist as a separate line from the suite rekey. Mail room boxes are usually corporation-controlled as well, so confirm who holds that responsibility before assuming it is yours.

Secondary suites and basement suites. Calgary has a large legal secondary suite stock, and these have a specific characteristic worth attention: the suite and the principal residence often share a building envelope, sometimes a shared entry vestibule, sometimes an interior connecting door. Every one of those doors is a security boundary between your tenant and either you or another household. The interior connecting door between a principal residence and a suite is the one people forget, and it deserves a proper deadbolt and a rekey on turnover like any other exterior door. Legal secondary suites in Calgary are also subject to safety code requirements including egress, which is a separate matter from locking hardware but tends to come up in the same conversation.

Multi-unit buildings you own outright. You control everything, which is where master key systems and restricted keyways become genuinely worth the investment.

How Does Calgary's Climate Affect Rental Hardware?

Calgary's cold and chinook freeze-thaw cycles produce a predictable seasonal spike in tenant lockout calls, frozen locks, snapped keys, and dead keypad batteries. These arrive as your emergency calls, at your cost, at the worst hours. A fall maintenance pass across a portfolio prevents most of them for a few dollars per door.

The failure modes are consistent:

• Frozen cylinders. Moisture inside a lock freezes and seizes it. Calgary's chinooks make this worse than steady cold, because each warm spell melts water into the keyway and each drop refreezes it inside the mechanism.
• Snapped keys. Brass loses ductility in the cold while lock grease thickens and demands more torque. A worn tenant key that survived summer breaks in January, usually in your door, usually at night.
• Dead keypad and fob batteries. Cold drains them fast. This is the leading smart lock complaint in Calgary rentals.
• Binding doors. Frames and doors move with temperature. A deadbolt that threw cleanly in August binds at -30°C, and a tenant forcing it is how you get a broken key.

The fix is a scheduled fall pass, ideally batched across a building on one visit: lubricate every exterior cylinder with powdered graphite or a dry PTFE spray, replace every keypad and fob battery whether or not it needs it, check every door for binding and alignment, and replace any cylinder that is already sticky before winter finds it for you. Avoid general-purpose oils and WD-40 as a long-term lock lubricant, since they dry out, attract grit, and gum up the mechanism.

Budget maybe $10 in graphite for an entire building and a couple of hours. Against that, weigh what a single after-hours tenant lockout costs you at a $50 to $150 emergency premium, plus the relationship damage of a tenant standing outside at -30°C because a lock you own seized. Our guide on preventing frozen door and car locks covers the full autumn routine, and if a tenant does get stuck, our guide on house lockouts in Calgary is worth passing along so they do not put a shoulder through your door frame.

What Should a Turnover Lock Checklist Look Like?

A complete turnover covers every keyed opening, not just the front door. Work the list in order: confirm possession is returned, count returned keys against the move-in report, rekey every exterior cylinder keyed alike, replace the mailbox lock, deactivate fobs through the corporation if it is a condo, then document everything with an invoice.

The working sequence:

• Confirm possession has actually been returned. This is the legal gate. Nothing else on this list happens before it.
• Count keys against the move-in inspection report. Unit door, building fob, mailbox, storage, laundry, parkade remote. Note discrepancies on the move-out report, since unreturned keys are chargeable.
• Rekey every exterior cylinder, keyed alike. Front deadbolt, front knob, back or patio door, garage entry door, and the interior door from an attached garage. That last one is the most commonly missed opening in the entire turnover.
• Replace the mailbox lock. Required to give the incoming tenant a mailbox key regardless, and mail theft is a live Calgary problem.
• Deactivate old fobs and codes. Through the condo corporation for condos, or your own system for buildings you control. A dead suite key with a live lobby fob is not a secure turnover.
• Reset smart lock codes and swap batteries on any keypad unit.
• Check and lubricate every cylinder while the technician is on site. The marginal cost is nothing and it prevents winter callouts.
• Flag failing hardware for replacement now, during vacancy, rather than during an occupied tenancy when section 23 notice applies and you need a tenant to be home.
• Issue and record the new keys on the incoming move-in inspection report, with counts.
• File the locksmith invoice against the unit. This is your documentation for both cost recovery and any future liability question.

The scaling insight for anyone with more than a handful of doors: batch it. Schedule your turnovers so a locksmith does four units on one visit rather than four visits. You pay one trip fee, your per-unit cost drops meaningfully, and you get consistent keying across the building. Landlords who treat lock work as a reactive emergency pay the emergency premium repeatedly. Landlords who treat it as scheduled maintenance pay the scheduled rate.

Work With a Locksmith Who Understands Rental Turnover

The rules that matter for a Calgary landlord come down to timing and documentation. Rekey between every tenancy once possession is returned. Never change locks on a tenant who still has possession, no matter what they owe you. If you change a lock mid-tenancy, put a key in the tenant's hand the same day. Count keys on the move-in and move-out reports, because unreturned keys are chargeable and undocumented ones are not.

Key And Lock Solutions works with landlords, property managers, and building owners across Calgary and the surrounding areas on exactly this cycle: turnover rekeys, keyed-alike unit sets, mailbox locks, master key system design for multi-unit buildings, restricted keyway conversions where key control actually matters, and scheduled fall maintenance passes that prevent the winter callouts. We will batch multiple units into a single visit so you are not paying a trip fee per door, and we will tell you plainly when a rekey is enough and when hardware genuinely needs replacing.

We will also ask whether the tenant has given up possession before we touch a door. That is not us being difficult. It is us keeping you on the right side of section 24.
