How Should Keys Be Handled When a Tenant Moves Out?

Neighbors Ask

The plain answer first

When a tenant moves out, three things need to happen with keys: they come back, they get counted, and the lock stops answering to any key that is not in your hands. The first two are about paperwork and habit. The third is about the lock itself, and it is the step that people skip most often.

Think of it this way. Even a tenant who handed back every key you gave them may have had one copied along the way, or lent one to a friend years ago. You usually cannot know. What you can do is change the lock so the question no longer matters. That is what rekeying is for, and it is why many property owners treat it as a routine part of every turnover.

The rest of this page walks through the process in the order it usually happens, from the move out walk through to the new lock, in a way that works for a single rental house, a duplex or a small building.

Get the keys back, and count them

Start with a simple list made when the tenant moved in: how many keys for the front door, the back door, any mailbox, a garage remote, a gate fob, a storage shed. If that list does not exist, make one now for the next tenant, and treat this move out as the lesson that proved why you need it.

At the move out, ask for every key to be returned in person, and write down what comes back. Do not count only the front door key. Mailbox keys, side gate keys, laundry room keys and garage openers all matter, because each one is a way in or a way to someone else's belongings.

If something is missing, note it plainly without turning it into an argument. Rules about deposits, deductions and notices vary by lease and by situation, so we will not pretend to tell you what is allowed. Your lease and a local housing resource are the right places to look. The locksmith side of it is simple: a missing key is a strong reason to rekey.

Why a counted key is not the same as a safe key

A returned key proves one thing: that key is back. It does not prove that no other copy exists. Key blanks are inexpensive and widely available, and nothing about a regular house key stops it from being duplicated. A small number of restricted key systems exist, but they are specialized and are not what most rentals have.

Picture a family that rented a house for six years. Over that time the kids had friends over, a babysitter had a key, the grandparent had a spare, and one key went missing and turned up again. When they leave and hand back two keys, the owner might feel finished. But the real number of people who could open the door may be a good deal higher than two.

This is the heart of why we suggest changing the lock, not counting harder. If you want to understand how widespread this problem is in ordinary homes, our guide on how many keys a household should keep gives a feel for how copies multiply.

Some owners worry that rekeying is a big, noisy job. It is not. Picture a locksmith arriving at an empty house with a case of small parts and a key machine: the work at each door usually involves taking out the cylinder, changing a handful of tiny pins, putting it back, and testing the new key several times. For a house with a front door, a back door and a side door, that is a modest visit rather than a project.

Rekey or replace, which one fits?

There are two ways to cut off old keys. Rekeying keeps the lock hardware you already have and changes the internal pins so that a new key works and the old ones do not. Replacing swaps the whole lock for a different one. Both achieve the goal, and the right choice depends on the condition of the lock.

If the lock is in good shape, turns smoothly and matches the look you want, rekeying is usually the simpler path. A professional removes the cylinder, changes the pin arrangement, and cuts new keys to match. Our page on rekeying your home explains the process in plain language. If the lock is worn, damaged, or of poor quality, replacement makes more sense, and the page on new lock installation covers that side.

We go deeper on how to choose in is it better to rekey or replace. One small tip: if you manage several units, ask whether the locks can all be rekeyed to the same key, which keeps your key ring manageable.

What to do between tenants

The empty days between tenants are the ideal moment to work on locks, since nobody is inside and nobody needs a key to get to work in the morning. Schedule the rekey after the old tenant is fully out and before the new one is given access. That order matters. If you rekey first and then the old tenant returns for a forgotten item, they will be stuck outside.

Check the condition of each lock while you are there. Does the deadbolt throw fully? Does the knob or lever work without sticking? Is the strike plate firm? Small repairs are easy to do in an empty unit. Our page on lock repair and adjustment describes what is typically involved.

Also consider the entry points people forget: the sliding door, the garage side door, the window latches that fasten from inside. Cabinet locks, shed padlocks and mailbox locks can need attention too. A walk around with a short list saves a second trip.

A good test before you hand over the keys: try each new key in its lock from both directions, with the door open and then closed, and confirm that an old key from the previous tenant no longer turns. If you still have an old key, use it. It takes seconds and gives you real proof, not just an assumption, that the change worked.

Smart locks and keypads at move out

Many rentals now use keypad or electronic locks, and these change the move out routine in a good way. Instead of counting physical keys, you can delete the old tenant's code and set a new one. But the work is not zero. You still need to know who can reach the settings, whether old codes were shared, and whether any backup key exists.

Electronic locks also have physical key backups, and those keys can be copied like any other. If the lock has a key override, treat it as you would any key: count, collect and consider rekeying the override cylinder. If the lock has an app, check which accounts have access and remove the old tenant's.

Multi unit buildings and shared doors

In an apartment building or a small complex, each unit has its own door, but there are often shared doors too: a main entry, a laundry room, a mail room, a gate. When a tenant leaves, the unit lock is the main concern, yet the shared doors deserve a thought as well. If many people hold keys to a shared door, ask how often those keys are collected and updated.

Some buildings use a master key system, where a single key can open many doors, so that a manager holds one key for all units. That is convenient, but it raises the stakes for key control, because losing one master key affects many doors. We explain how these systems work in what a master key system is and whether you need one.

Our guide on apartment complexes, locks and the resident role is written from the tenant's viewpoint and shows how responsibilities are often divided.

A last thing to consider in a shared building is signage and communication. Residents who know that locks are routinely changed at each turnover feel better about the building, and they are more likely to report a lost key promptly. A brief note to the neighbors that an apartment next door is being re keyed, when appropriate, can also prevent worry about someone working on a door.

Keep a record, even a simple one

You do not need special software. A notebook or a spreadsheet with one line per door and one column per event works well. Record the date a lock was rekeyed, how many keys were cut, who got them, and the date they came back. Over time, that record answers questions that otherwise cause headaches.

It also helps when you call a locksmith. If you can tell them the type of lock, the number of doors and how many keys you want, the visit goes more smoothly. Our guide on what to have ready when you call a locksmith lists the details that matter most.

Property managers who handle many homes sometimes build this routine into a regular workflow. If that interests you, property managers and the rekey at turnover workflow describes how it can look.

Storage matters as well. Keep spare keys for your units in a locked box or cabinet, labeled with codes rather than addresses, so that a lost label never gives a stranger a map. Limit who can open that cabinet, and write down when keys leave it. Many small landlords keep their spares in a kitchen drawer, and that works until the day it does not.

If you are the tenant moving out

Tenants have a part in this as well. Gather every key you were given, including the ones tucked in a drawer or hanging on a hook by the back door. Do not hand over copies you made yourself to friends, and if you did make copies, return them or tell the landlord, so everyone is on the same page.

Return keys in a way that leaves a record. A short note or message listing what you returned, and when, protects you if a question comes up later. Do not leave keys inside an unlocked home, under a mat or in a mailbox. Hand them directly to the landlord or manager, or follow the written instructions in your lease.

If a key breaks or you lose one close to move out, say so early. It is much easier to sort out a single lost key with a conversation than to let it become a surprise at the final inspection.

Where mobile service helps in this part of California

Rentals in our area range from houses in Redding and Anderson to cabins in Lakehead and apartments in Yreka and Mount Shasta. A mobile locksmith with a service van can come to the property, rekey the locks and cut new keys on the spot, which helps when you manage a house that is a long way from town or when a turnover date is close.

Whether the unit sits in the valley heat or in the mountain snow, the work is the same. The rental sits empty, the old keys need to stop working, and new keys have to be in the right hands by move in day. If you want to talk it through, use the request form and describe how many doors you have.

We cover every community in the area, including Redding, Anderson and Yreka, so you can see the details for your own town.

Winter and summer both bring their own wrinkles. In the mountain towns, snow and ice can make a lock stiff during a January move out, and a little patience helps. In the valley, a July turnover means a hot, dry door and a swollen frame can bind a latch. In either case, mention any sticking to the person doing the lock work, since the cure may be an adjustment, not a new lock. Our pages on Mount Shasta and Shasta Lake say a little about how weather shapes local lock needs.

A short turnover routine to copy

Every landlord ends up with a routine. Here is a plain one you can adapt. Change anything that does not fit your situation, and add what your lease and local rules call for.

Walk it through once and you will see that most of the work is organizing, not locksmith labor. The lock change itself is a small part of the job, but it is the part that decides who can open the door.

• Collect all keys, remotes and fobs, and write down what came back.
• Compare the list against what was issued at move in.
• Rekey or replace the locks after the tenant is out and before the next one is in.
• Test every key on every lock, and cut extras only as needed.
• Note the date and the number of keys issued to the new tenant.
