Do You Need to Change the Locks Between Tenants? A Practical Guide for Landlords and Renters

The Short Answer for Both Sides

Every time a tenant moves out, the same question comes up: do you change the locks before the next person moves in? If you own the place, you might be tempted to skip it and save a few bucks. If you’re the one renting, you’re wondering who else still has a key to your new home. Either way the answer is the same, and it’s simpler than most people expect. You almost never need to replace the locks. You just need to rekey them. Those two get mixed up constantly, so let’s clear that up first.

Rekey or Replace?

First, the part that trips everyone up. Rekeying and replacing sound like the same thing, but they’re two different jobs with very different costs. Rekeying changes the little pins inside the lock so the old keys stop working and a new key takes over, while the lock itself stays right where it is on the door. Replacing means taking the whole lock off and putting a new one on. For moving one tenant out and the next one in, rekeying is the one you want. It’s quick, it’s cheap, and it covers the whole job. You only really need to replace a lock when:

For everything else, a rekey does it. We go deeper on the difference in rekeying versus changing locks, and if you want to know what it runs, our guide on what it costs to rekey a home breaks that down.

Why It’s Worth Doing Every Single Time

When a tenant moves out and gives the keys back, you still don’t know how many copies are floating around. Keys are cheap and quick to cut, and over a year or two, one can easily end up with:

The person who just moved out usually isn’t the worry. It’s everyone they ever handed a key to. A single rekey shuts all of them out at once, and that’s the whole reason to do it every time the place changes hands. It costs a landlord almost nothing, and it’s the only way to know for sure that nobody from before can still get in. Think back to your own last move. Did every spare key you ever cut make it back onto one ring? For most of us the honest answer is no, and a landlord has no way of knowing either way.

What Renters Can Ask For

If you’re the one moving in, you’re allowed to care about this, and bringing it up doesn’t make you a difficult tenant. Before you sign or before you move your things in, it’s completely fair to ask whether the locks were rekeyed for you. A good landlord has already taken care of it, or will do it without any fuss, because they’d want the same in your shoes. If it hasn’t been done, a polite ask is usually all it takes. And if a lock ever leaves you feeling unsafe while you live there, say something. It’s your home for as long as you’re paying rent, and wanting to feel secure in it is a pretty reasonable thing to ask. Plenty of new renters quietly wonder about this on their first night and never bring it up. You don’t have to lose sleep over it. One question to the landlord, or one rekey, and it’s off your mind for good.

What to Look At While the Place Is Empty

An empty unit between tenants is the easiest time there is to give the place a real once-over. Nobody’s furniture is in the way, and you can actually reach every door and window without working around someone’s life. While you’ve got a locksmith there rekeying anyway, take five minutes and check the basics:

Catching a loose deadbolt or a dead porch light now, while the place is empty, is a lot easier than hearing about it from a nervous tenant a month down the road.

How Smart Locks and Keypads Change Things

More landlords are moving to keypad locks and smart deadbolts, and move-out is where they really come in handy. If you go that way, you don’t call anyone to rekey. You delete the old tenant’s code, set a new one, and you’re done, which does the exact same job as a rekey. There are no physical keys to chase down, and some systems let you change the code straight from your phone without driving over. The only catch is that you have to remember to do it. An old code left working is the same mistake as an old key still floating around, so make resetting the code part of your move-out routine every time, just like a rekey.

One Thing to Keep Separate

Quick but important: none of this is about changing the locks on someone who still lives there. Rekeying between tenants happens when the place is empty and switching hands. Locking out a tenant who’s still living there, over unpaid rent or an argument, is a completely different situation. Laws on landlord lockouts vary by state and even by city, and changing the locks on a current tenant without following the proper legal process can expose a landlord to serious consequences. If someone’s still in the unit, that’s not a locksmith call, it’s a step to handle carefully and by the book.

How to Get It Done Right

Once the rekey becomes a normal part of every move-out, it stops being a decision and just turns into a step, like cleaning the carpets or touching up the paint. A few habits keep it painless:
