Rekey After a Breakup, Divorce or a Roommate Moving Out

The question after a breakup or a roommate move-out is not whether the person is a threat. Most are not. The question is whether you want your front door to depend on someone else remembering to return a key, or never having copied it. A rekey removes that dependence in under an hour, without a confrontation.

This guide covers when a rekey is the right move, where the legal line sits for renters and co-owners, everything beyond the front door that needs changing, and what the visit looks like.

When is a rekey the right move?

Rekey when someone who once had a key no longer lives there and you would rather not rely on them. That covers an ex-partner who moved out, a roommate whose name came off the lease, an adult child who moved back out, or the friends and family who were handed spares along the way.

Rekeying keeps your existing locks. A locksmith swaps the pins inside each cylinder so old keys stop working, then cuts you a fresh set. It takes about 10 minutes per lock, and if your locks are all one brand they can go on a single key at the same visit. Our rekey service page explains the basics, and the same visit covers keys that were never returned.

Rekey even if the key was handed back. A returned key tells you nothing about copies made over months or years. Rekeying settles it.

Where is the legal line?

This is general information, not legal advice. The rules depend on who is on the lease or the title, and they change, so check current rules or ask a lawyer about your situation.

If you own the home alone

You can rekey whenever you like, as long as the other person has actually moved out. Someone who still lives there, even with their name on nothing, may have tenant-like rights in California, and locking them out can turn a breakup into a legal dispute. Once they have moved out with their belongings, a rekey is routine.

If you are married or both names are on the title

Both owners generally have a right to be in the home until a court order says otherwise. During a divorce, a family law attorney can ask the court for an order that addresses who stays in the house. After that order, or once the other person has moved out by agreement, rekeying is straightforward. Before it, talk to your attorney first.

If you rent

Most California leases require the landlord’s permission before you change or rekey locks, and they require you to give the landlord a copy of the new key. Read your lease, ask in writing, and expect a yes in most cases. Many landlords simply book the rekey themselves as a tenant turnover.

If the roommate who left is still on the lease, they keep a legal right to the unit until the landlord releases them. Get that sorted with the landlord before rekeying. Our guide on rekeying between tenants in California covers the landlord side.

If there is domestic violence

California Civil Code sections 1941.5 and 1941.6 let a tenant who is a victim of domestic violence, sexual assault or stalking have the locks changed. With the required documentation, the landlord must change the locks within a short window, currently 24 hours, or the tenant can change them and give the landlord a key. Section 1941.5 applies when that person is not a tenant of the same unit; section 1941.6 covers a co-tenant and requires a court order excluding them.

The details matter, so check the current text and talk to a domestic violence advocate or an attorney. They can help with the protective order and the paperwork, and we can handle the locks the same day.

What else did they have access to?

The front door key is the obvious one. Anyone who lived with you also knew or held most of this:

Work through it in one sitting. Delete their user from the smart lock app before you do anything else in it. Clear the garage opener’s memory from the button on the motor unit and re-pair only the remotes you still have. If a smart lock is on the door, a rekey and reset visit covers both the key override and the electronics.

Rekey or replace?

For most breakups, rekey. The locks are fine; the key list is the problem. Our rekey vs. change locks guide covers the exceptions: worn locks, mismatched brands, or a security upgrade you wanted anyway.

The one strong reason to replace is that you never want to hand out a key again. A keypad deadbolt gives each person their own code, and deleting a code takes ten seconds. When the next roommate moves out, there is nothing to collect. That setup suits shared houses in Pacific Beach and near SDSU in the College Area, where the roster changes every year.

If you stay with keys, ask for a keyed-alike rekey so the whole place runs on one key. Fewer keys to hand out means fewer keys to chase later.

When should you do it?

The same day they move out, once the last box is gone. Book the locksmith for that afternoon or the next morning. Waiting a week or two is the most common mistake, and it is the window when a key most often gets used to collect one more thing while nobody is home.

If the move-out is spread over several trips, wait until the last one so you are not rekeying twice. If they need to come back for something after the rekey, meet them there, or give a temporary keypad code and delete it afterward.

What does the visit look like?

1. We confirm you have authority over the property. Photo ID with the address, a lease or a deed is enough. This step is what stops anyone else from rekeying your door.
2. We walk every exterior door with you and count cylinders, including the door from the garage into the house.
3. Each cylinder comes out, gets new pins and goes back in. About 10 minutes per lock.
4. We test every door with the old key and the new key in front of you.
5. You get a fresh set of keys, cut on the spot. Extras are available if the landlord or a trusted friend needs one.

Most apartments in Hillcrest and North Park have one or two cylinders and take well under half an hour. A house with a garage and gates takes about an hour.

What does it cost?

A rekey is priced as a service call plus a per-cylinder fee. In San Diego, a one-door apartment typically lands roughly in the low $100s and a three-door house roughly in the $150 to $250 range, depending on the locksmith. A keypad deadbolt adds the cost of the lock plus install labor, which commonly runs $100 to $250. Our own rates are on the pricing page, and what rekeying costs in San Diego breaks down each line.

Next step

Once the move-out is done, book a home rekey for the same day. Tell us how many doors, whether you rent or own, and whether you want a keypad on the front door so this is the last time you deal with it.
