If you’re the sole owner or the only name on the lease, you can rekey the moment your ex moves out, no permission needed. If you’re both on the title or both on the lease, the front door isn’t yours to unilaterally control until that gets sorted out, usually through a family law attorney or a conversation about who’s staying. Either way, a locksmith can be at a San Diego home the same day, and rekeying a standard door runs $25 to $40 per cylinder. Here’s how to sort out which situation you’re actually in, and what to do about it.
Can you legally change the locks after a divorce or breakup?
If your name is the only one on the deed or the lease, yes. You don’t need your ex’s permission to rekey a home that’s legally yours. This is true whether the split was mutual or messy. The moment someone moves out of a property they don’t own or lease, their right to a working key goes with them.
It gets more complicated when both names are on the mortgage or the lease. Legally, you’re both still entitled to access until a court order, a signed agreement, or a lease amendment says otherwise. Rekeying a shared property without that paperwork can create a real legal problem, separate from the locksmith visit itself. Whether you should is a question for a family law attorney, not a keyholder.
One exception matters here. California gives documented survivors of domestic violence a statutory right to have locks changed on short notice, regardless of whose name is on the lease. If that’s your situation, our guide on tenant rekey rights in California walks through exactly how that provision works and what documentation a locksmith or landlord will ask for.
How fast can a locksmith come out in San Diego?
Same-day service is standard across San Diego County most weekdays. Call before noon and a rekey is usually done that afternoon. Evenings and weekends are available too, though calls after roughly 10 PM carry a standard after-hours fee like any other locksmith call.
Speed matters more here than in a typical rekey job. If the relationship ended badly, or your ex still has a key and knows the garage code, every day that passes is a day someone you no longer trust could let themselves in. Most people in this situation want it handled today, not on the next convenient slot.
Rekey or replace: which one do you actually need?
For most breakups, a rekey is the right call. It changes the internal pins in your existing deadbolt so your ex’s old key stops working, while the hardware itself stays exactly the same. A standard door runs $25 to $40 per cylinder, and three doors typically lands around $165 all-in when the locks are in decent shape. That’s the fast, affordable reset most people need.
Replacement makes more sense in a narrower set of cases: a lock your ex damaged, hardware old enough that you’d upgrade anyway, or a move to a smart lock instead of a physical key. Full lock replacement of three deadbolts with mid-range hardware in San Diego typically runs $405 versus $165 to rekey the same three doors. Our rekey versus replacement cost breakdown covers the tradeoffs in more depth.
What if you’re renting, not the homeowner?
Most California leases require landlord permission before you touch the locks, even if the person moving out was your partner rather than a formal co-tenant. In practice, most landlords approve this same day once you explain the situation. Send a text or an email and keep it in writing.
If your ex was actually named on the lease alongside you, that’s a different situation than a partner who simply lived with you unofficially. A named co-tenant generally has an ongoing right to the unit until the lease is formally changed, similar to the shared-ownership question above. Our guide on tenant rekey rights in California covers both scenarios and the domestic violence exception in full.
What if you’re both on the mortgage or the lease?
This is the situation locksmiths get asked about most and can help with least on the legal side. If you and your ex both own the home or both signed the lease, neither of you has an automatic right to lock the other one out. Doing it anyway can trigger real consequences in a divorce proceeding or a landlord-tenant dispute.
The practical path is usually one of three things: a temporary agreement between you and your ex about who stays, a court order addressing exclusive use of the residence, or a lease amendment removing one name. Once that’s settled, the rekey itself takes a locksmith less than an hour. The paperwork is the hard part, not the hardware.
What else needs to change besides the front door?
A rekeyed deadbolt handles one entry point. Most exes still have access to more than that, and these are the ones people forget until it’s too late.
Garage keypad codes. If your ex ever used the garage, they know the code. This takes thirty seconds to change and it’s the single most overlooked access point after any relationship ends.
Alarm system codes. Change the code the same day you rekey, not after. Most systems let you do this from an app or the panel in under three minutes.
Smart lock codes and shared apps. If you already have a smart lock, delete your ex’s code and remove them from any shared home app immediately. This is faster and cheaper than a physical rekey, and it should happen even if you’re also changing the physical locks elsewhere.
Hidden spare keys. If your ex ever knew where you kept a spare, under a planter, above the door frame, in a lockbox with a code they know, move it or change the code today.
Mailbox and gate fobs. In shared apartment or condo complexes, contact your HOA or property manager about deactivating any fob or access card your ex still carries. This is handled at the building level, not by a locksmith.
Vehicle keys and remotes. If your car is in your name, consider whether your ex still has a working key or fob. This is a separate service from a house rekey, but worth doing at the same time.

Is a smart lock worth installing during a breakup rekey?
If you’re already paying for a service call, it’s worth considering. A smart lock installation runs $180 to $420 depending on the hardware, and it replaces the ex-with-a-key problem entirely. Instead of wondering who has a physical copy floating around, you assign and delete digital codes from an app in seconds.
This matters even more with kids in the picture. Custody exchanges and family members needing occasional access get simpler with a code you can turn on and off, rather than tracking who has which cut key. If you’re weighing the two options, smart lock versus deadbolt: which is actually safer covers the practical differences without a sales pitch.
Frequently asked questions
Can I change the locks after a breakup without my ex’s permission?
Yes, if you’re the sole owner or the only name on the lease. If you’re both on the title or both on the lease, you generally need an agreement, a court order, or a lease amendment before rekeying, since you both currently have an equal legal right to the property.
How much does it cost to rekey after a divorce or breakup?
A standard door runs $25 to $40 per cylinder. Three doors typically lands around $165 all-in, including the service call. Full replacement of the same three deadbolts with mid-range hardware runs closer to $405, which is why most people rekey instead unless the hardware needs upgrading anyway.
How fast can a locksmith come out in San Diego?
Same-day service is available most weekdays across San Diego County. Call Swift Key San Diego at (858) 400-4082 before noon and the job is usually done that afternoon. Evening and weekend appointments are available too.
What if my ex still has the garage code or an alarm code?
Change both the same day you rekey the front door. A garage keypad code takes about thirty seconds to reset, and most alarm systems let you change the code in under three minutes through an app or the panel. These are the two most commonly forgotten access points after a relationship ends.
My ex and I are both on the mortgage. Can I still rekey?
Not without something in writing first, whether that’s a mutual agreement, a court order addressing who stays in the home, or a lease amendment if you’re renting. Once that’s settled, the physical rekey itself takes a locksmith less than an hour.
Should I rekey or fully replace the locks?
Rekey if the hardware is in good shape and you just need your ex’s key to stop working. Replace if the locks are damaged, outdated, or you want to move to a smart lock. Rekeying three doors runs around $165. Replacing the same three with mid-range hardware runs closer to $405.
