Not rekeying between tenants is a bigger risk than people think

Talked to someone recently who skipped rekeying between tenants to save some money and a phone call to a locksmith. I think its worth walking through why that's a worse trade than it looks.

Florida doesn't have a statute that says you must rekey between every tenant. But skipping it creates a real liability gap most self-managers don't think about until something happens. Every previous tenant, every maintenance person they let in, every friend or ex-partner who ever had a key, still has access to your property after they're gone. Landlords have a general legal duty to take reasonable steps to keep tenants safe, and an un-rekeyed lock after a known change in occupants is exactly the kind of thing that undermines that defense if something goes wrong later.

The math doesn't really make sense to skip it. A basic rekey typically runs $75-250 depending on the number of doors and whether you hire a locksmith or do it yourself with a rekey kit. Compare that to what you're exposed to if a former occupant lets themselves in and something goes wrong.

The other thing people miss: rekeying isn't just the front door. Back doors, garage entry, sometimes a mailbox lock, any access point that had a key in someone else's hands before.

Anyone here skip this on a property and regret it, or is this just standard practice for everyone by now?

It is foolish to NOT rekey all entry locks as soon as the tenant is out, for multiple reasons. For $100 you can buy a Kwikset pin kit to rekey your handsets and deadbolts yourself. 5 minutes of work per cylinder to rekey so all entry locks require only one key (vs. multiple keys per door!), AND you can easily "Master" pin them as well, which gives you access to all (or a group, or a single MF building) properties with one key, while the tenants each have uniquely keyed units for their own access and security. 

Learning to rekey multiple lock brands is a little more effort, but there are kits for pinning multiple common brands as well. Some are easier, some are a little tricky to accomplish, but still a huge savings vs. what a locksmith charges for every cylinder. Just don't drop your open pin box!

      Thanks for the input Richard. The master-pinning tip is a good one. We typically like to use Kwikset as it's much easier to rekey. We hire it out to a locksmith on turns since we're running volume, but same principle either way, every unit gets rekeyed between tenants, no exceptions.

    When I first implemented the process, we had an in-house maintenance staff, and around 850 units. The maintenance supervisor, a couple of the "service call" handyman type guys, myself, and an admin person all learned how to repin, and we made up sets in advance during slow times, to speed the R&R process when needed. The other part of the "key" situation was to have a key cutter in the maintenance area, and a defined system for handling keys when multiple people needed them at different times. Before implementing the system, someone would be out at a property and find they had keys that did not work, or, "someone" never returned the keys to the proper place, and we would end up with NO keys for access...at a very inopportune time. 

    The hilarious thing is, later, at another large PM company, we were taking over management of several thousand units of Military housing. During the process, the project managers decided to utilize the same key "system" as the Military did...which as you might imagine was VERY costly...and ultimately did not solve the problems I had solved years earlier, for pennies. The Military had actual large, computer access controlled "safes" that held keys for all of the units. It was fine for tracking who removed the keys, but did nothing for solving the real life issue of either finding a key (a lost key is a lost key, computer tracking or not), or of ensuring a key was available when needed. You have to address the human factor!

      That is a wild story. Its funny how the government likes to spend money LOL! Crazy that you guys onboarded thousands of Military homes. I have not had the pleasure of doing that just yet. Learning how to repin is smart, cheaper and faster than calling someone every time a set needs to change.

    We treat rekeying as part of every standard turnover. Compared to the overall cost of preparing a unit for the next resident, it's a relatively small expense that can significantly reduce risk.

    It's also one of those things that builds trust with new residents. Being able to tell them they're the only ones with working keys after move-in provides peace of mind and sets a good tone from day one. For us, it's not an area where it makes sense to cut corners.

    I wonder how an insurance company would view a claim if they found out the property wasn't rekeyed for the new tenant?

    I think rekeying is just part of the turnover process. It's one of those relatively inexpensive things that can prevent a much bigger problem later. With smart locks and rekeyable locksets becoming more common, it's also getting easier and faster to do than it used to be. Definitely not an area where I'd try to save a few bucks.

    Someone who does not rekey / change locks in between tenants,  is a fool that should not be in the business.  Just a matter of time before something really bad happens...

    These cost less than $40 have a master key cylinder and allow easy re-keying of tenant cylinder. .. There's just no excuse not to rekey

    That’s a good point. The cost of rekeying seems tiny compared to the potential downside. Have you found there are any other “small expenses” that newer landlords often skip but almost always end up regretting later?

    @John Walbridge - Great post! 

    The cost of rekeying is insignificant compared to the potential liability, and it also gives both me and the new tenant peace of mind.

    I've also heard of others switching to smart locks/electronic keypads for ease. Curious if you or others have switched to smart locks or electronic keypads for long term rentals. I've been seeing more investors go that route to eliminate physical key handoffs altogether.

    You are right. Skipping the rekey between tenants is one of those shortcuts that looks like a small savings until something goes wrong. We treat it as standard practice on every turnover. Every previous tenant, maintenance person, or friend who ever had a key still has potential access if the locks are not changed.

    The cost of a basic rekey is low compared to the liability exposure if a former occupant or someone they gave a key to enters the property later. It also gives the new tenant peace of mind, which helps with retention. We always include all exterior doors and any other keyed access points.

    In our experience the owners who skip it occasionally end up regretting it. Better to make it automatic on every move out so it never becomes a question.

      Thanks for the response Amit. We operate the exact same way

    @John Walbridge I totally agree. However, I know there are many investors who self-manage and do not re-key between tenants. Personally, I think the relatively small cost of rekeying is well worth the added security and peace of mind. It is a simple step that can significantly reduce potential liability.

       Hey Janice , Thanks for the input. You are 100% correct. The liability is just not worth it!

    The best thing I ever learned about that I'm so glad I did on here even before my first property was Landlord Locks out of Indiana.

    I have one key that works in all locks on all properties. All tenants only have one key for all doors they access unless they also rent a garage spot.

    But the best part is, the core system. Easy swap of locks during turnover. Takes a whole two seconds per unit door.
