Why Tenant Turnovers Require Immediate Rekeying

Of course! Here is a 1800+ word SEO-optimized article crafted to your precise specifications.

Alright, let’s talk about one of the most critical, yet often overlooked, tasks in property management: what to do the second a tenant moves out. If you’re a landlord, a property manager, or even just someone who rents out a basement apartment, you know the drill. The place is finally empty, you’ve got a cleaning crew scheduled, and you’re already listing the unit online. It’s tempting to just take a deep breath and cross “tenant turnover” off your massive to-do list.

But hold on. Before you do that, we need to have a serious, friendly chat about those locks. And we’re not just talking about a quick visual inspection. We’re talking about the non-negotiable, absolutely-must-do-immediately step of rekeying or changing every single lock on that property.

Why the urgency? Well, let’s just say that an old key in the wrong hands is a one-way ticket to a world of problems you definitely don’t want to deal with.

Why We Never, Ever Skip This Step

Think about it. You’ve just had a tenant move out. You might have had a great relationship with them, and you trust them completely. That’s fantastic. But can you be 100% certain about everyone they ever gave a key to? What about the friend who watered their plants? The family member who house-sat? The contractor who did some work six months ago? That copy they made “just in case” and then lost in a junk drawer?

See where we’re going with this? The moment a tenant leaves, you lose all control over who has access to your property. And that’s a massive security risk. It’s not necessarily about assuming the previous tenant has bad intentions—it’s about acknowledging the simple, uncontrollable fact that keys have a way of multiplying and circulating. Forgetting to rekey is basically like leaving your front door wide open and hoping nobody unpleasant wanders in. Not a great strategy, right?

We’ve seen it all at Roy’s Locks & Keys here in Markham. The stories range from the mildly annoying (a former tenant “popping in” to grab a package they forgot) to the outright terrifying (unauthorized individuals gaining access). It only takes one incident with a burglar who somehow got their hands on an old key to make you wish you’d made that call to a locksmith near you on day one.

The Hidden Costs of Skipping the Rekey

So, what’s the real cost of not rekeying? Let’s break it down, and we’re not just talking about the price of the service itself.

• Voided Insurance: This is the big one. Most insurance policies have clauses that require you to maintain a reasonable standard of security. If you have a break-in and it’s discovered the point of entry was unlocked or accessed with a key you failed to secure, your insurance company might deny the claim. Suddenly, the cost of replacing stolen goods and repairing damage comes straight out of your pocket. That’s a financial hit that makes a simple lock change look like a bargain.
• Liability Nightmares: What if someone with an old key enters the unit and gets injured? You could be facing a serious liability lawsuit. The legal fees alone would be astronomical.
• Peace of Mind (Priceless): You can’t put a price on sleeping soundly at night knowing your property, your new tenants, and your investment are truly secure. It’s the foundation of responsible property management.

Rekeying vs. Full Lock Change: What’s the Difference?

This is a question we get all the time. Is it enough to just rekey, or should you go for a full lock change? IMO, it depends on the situation.

Rekeying is the process of taking apart the existing lock cylinder and rearranging its internal pins so that the old key no longer works. A new key is then created for the new pin configuration. It’s a fantastic, cost-effective solution when the existing hardware is still in good shape, modern, and sturdy.

A full lock change means completely removing the old lock and deadbolt and installing brand-new hardware. This is the way to go if:

• The locks are old, rusty, or damaged.
• They’re a low-quality brand that’s easily compromised.
• You want to upgrade to a newer, more secure style (like a smart lock or a high-security cylinder).
• The keys are lost entirely, and you have no way of knowing who might have them.

For most tenant turnovers, a professional rekey does the trick perfectly and is easier on the wallet. But if you’re dealing with a frozen door lock from a harsh Canadian winter or hardware that’s seen better days, a full replacement is your best bet. The team at Roy’s Locks & Keys can quickly assess your situation and recommend the most secure and economical path forward.

Here’s a quick table to break it down:

Beyond the Front Door: What Else to Check

When we talk about rekeying, we don’t just mean the obvious front door deadbolt. A thorough security sweep is crucial. Any seasoned property management locksmith will tell you to check every possible entry point:

• Back door and patio sliders: These are common weak points.
• Garage entry doors: Often forgotten!
• Windows with locking mechanisms: While not always keyed, their locks should be inspected for function.
• Mailbox keys: Especially in apartment complexes.
• Sheds or external storage units on the property.
• Apartment key fob systems: These need to be deactivated and reprogrammed for the new tenant. You’d be surprised how many old fobs are still active.

It’s also a perfect time to check other hardware. Do the doors close properly? Are the locking hinges secure? Is there a need for additional security measures like a panic bar installation for a commercial property or a multi-unit building? A turnover is your chance to do a full security audit.

The “Oh Crap” Moments: When You Need an Emergency Locksmith

Even with the best plans, things happen. Maybe a tenant lost their keys the day before moving out. Perhaps an eviction didn’t go smoothly, and you need the services of an eviction locksmith to quickly and legally secure the property. Or maybe you’re doing a final walk-through and discover a frozen door lock that won’t budge.

This is where having a trusted, local, and mobile locksmith on speed dial is a game-changer. A mobile locksmith like us at Roy’s Locks & Keys means we come to you. We’re based in Markham and service the wider area, including places like Greensborough, so help is never far away. Whether it’s a planned rekey or an emergency locksmith situation, a van stocked with everything needed for a lock change service is just a phone call away.

FYI, the same goes for your wheels. If a tenant turnover involves securing a parking garage or dealing with a lost car keys situation for a company vehicle, a good auto locksmith or car locksmith can handle that, too. It’s all about comprehensive security.

Making It Easy and Affordable

We know that as a landlord, you’re constantly balancing cost with necessity. The good news is that rekeying is one of the most affordable security investments you can make. The price is a small fraction of what you’d pay to deal with the aftermath of a security breach.

When you factor in the cost of potential theft, vandalism, insurance headaches, and legal fees, it’s a no-brainer. It’s a proactive step that saves you a massive amount of money and stress down the road. Plus, it shows your new tenants that you take their safety seriously—which is a great way to start a positive landlord-tenant relationship.

Your Action Plan for a Secure Turnover

So, let’s make this simple. Here’s your checklist for a secure tenant turnover:

1. Schedule the Locksmith in Advance: Don’t wait. The moment you have a move-out date, call your locksmith. At Roy’s Locks & Keys, we work with property managers all the time to sync up with their schedules.
2. Do a Full Walk-Through: Identify every lock that needs attention, not just the front door.
3. Choose Rekey or Replace: Based on the condition of your hardware, decide with your locksmith which option is best.
4. Get Multiple Keys Cut: Get at least three copies of the new keys for your records and for the new tenants.
5. Update Any Electronic Systems: Deactivate old apartment key fobs and codes, and program new ones.
6. Breathe Easy: Know that your property is now secure and ready for its next responsible occupant.

Your Top Questions, Answered

We literally get asked these questions every single day.

1. Can’t I just rekey the locks myself with a kit from the hardware store?
You could try, and hey, more power to you if you’re a DIY master. But in our experience, those kits are finicky, easy to mess up, and often result in a lock that’s more fragile and easier to pick. A professional locksmith has the tools and expertise to do it quickly, correctly, and with a guarantee that the lock will still function perfectly. It’s one of those jobs where the small professional fee is worth every penny for the assurance it brings.

2. How long does it actually take to rekey a property?
For a standard single door, a pro can often rekey the lock in under 15 minutes. For a whole unit with multiple doors, you’re usually looking at an hour or so. It’s incredibly fast, which is why there’s no excuse not to do it immediately. Our mobile locksmiths can often do it on the spot without disrupting your cleaning or repair schedule.

3. What about smart locks? Do they need to be “rekeyed”?
This is a great modern question! With smart locks, you don’t rekey the physical cylinder (unless you want to). Instead, you simply delete the old users’ codes, fingerprints, or smartphone access from the app and create new ones for the incoming tenants. It’s arguably even faster and more secure. We can help you with that, too, if you’re looking to upgrade.
