What does it mean to rekey locks?
Rekeying changes the inside of a lock, not the outside. A standard pin tumbler lock holds a set of small pins that line up only for the one key cut to match. When we rekey, we take the cylinder apart, swap the pins for a new combination, and cut keys to fit it. The lock stays on your door and the finish stays the same. The old keys, including the one a former tenant never handed back, no longer turn it.
That is why rekeying is usually the more economical route compared with replacing every lock in a house. You are paying to change who can get in, not to buy new hardware. If your locks are in decent shape and you like how they look, rekeying solves the actual problem, which is that you do not know who is holding a copy.
Not every lock is a good candidate. If a cylinder is worn, a deadbolt is loose in the door, or the hardware is already failing, a rekey only gives you a new key for a lock that is on its way out. We look at that during the visit and tell you plainly, so you do not spend money on a lock that will give you trouble next month.
When should you rekey: moving, buying a house, tenants or lost keys?
The reasons people call us for a lock rekey are usually simple. Somebody else might have a working key to your door, and you want that to stop. These are the situations we see most often:
- Rekey locks after moving: you cannot know how many copies the previous occupant made, or who they lent one to. Relatives, cleaners, contractors and dog walkers all tend to end up with keys.
- Rekey locks after buying a house: closing hands you a set of keys, but not a list of everyone else who has one. Doing it before the first night in the house is the cleanest way to start.
- Rekey locks after a tenant moves out: a tenant turnover rekey means the next resident gets a door that previous residents cannot open, no matter how many copies were made along the way.
- Rekey locks after losing keys: if keys vanished along with something that shows your address, such as a wallet, a bag or a car, rekeying is the safer answer. If they slipped behind a couch cushion for an hour and turned up, you probably do not need it.
- After a breakup, a roommate leaving, or an employee parting ways: the door should stop honoring a key that no longer belongs to someone you trust.

Call (213) 577-1366Can you rekey all house locks to one key?
Yes, in most cases. If you want to rekey all house locks, we can usually set the front door, back door, side door and any garage entry door to work with a single key. This is called keyed-alike, and it saves you from carrying a fistful of keys. It works best when the locks share a compatible keyway. If your house has a mix of brands put in over the years, one or two cylinders may need to be swapped so everything fits the same key. We check that on arrival and explain what we find before we change anything.
A house rekey is also a good time to decide how many keys you really need. Two people living in the house do not need six keys in circulation. Fewer keys means fewer chances for one to wander off.
How does our lock rekey service work, step by step?
There is nothing mysterious about the process, and you are welcome to watch. Here is how a typical visit goes:
- You call (213) 577-1366, which is answered at any hour. Tell us how many doors, whether they have knob locks, deadbolts or both, and whether it is a house, apartment or business.
- A mobile van comes to you with pinning kits and key blanks on board, so the work usually happens right at the door.
- We inspect every lock first. We check that the key turns smoothly, the cylinder is not worn, the latch lines up with the strike plate, and the deadbolt fully throws.
- We remove each cylinder, repin it to the new combination, and cut the new keys. If you asked for keyed-alike, we match the locks to one key.
- We test every lock with the new key several times, and confirm the old key no longer operates it.
- We reinstall everything and test the door from both sides, open and closed. Then we hand over the keys and tell you exactly which keys work which locks.
What affects the cost of lock rekeying?
We do not publish flat numbers on this page because the work really does vary. Here is what moves the cost up or down, so you can see where an estimate comes from:
- How many cylinders: each lock is repinned individually, so the job scales with the number of doors, not just the number of visits.
- Lock type and keyway: standard residential knobs and deadbolts are the simpler end. Restricted or high-security keyways take more care and sometimes depend on the manufacturer.
- Condition of the hardware: a smooth, healthy lock is quick to rekey. A sticky or worn one may need repair first, and that is a separate line item we would explain before starting.
- Keyed-alike or separate keys: matching several locks to one key is a little more work than treating each one separately.
- Number of keys cut: more copies mean more blanks and more cutting.
- Time of day: after-hours and holiday calls are handled by the same company, but late-night work can be priced differently than a weekday visit.
- Location and access: where we are coming from and how easy the doors are to reach both play a role.

Call (213) 577-1366Should you rekey, change the locks, or replace them?
Rekeying is the right answer when the hardware is sound and the only concern is key control. If you want a different style, a stronger deadbolt or new finish, that moves into changing your locks or full lock replacement, which we handle as separate jobs. And if you are leaning toward keypads or app-based access, that is a conversation for smart lock installation, not a rekey.
A simple way to decide: if the lock works well and you just do not trust the keys, rekey it. If the lock itself is the problem, replace it. We would rather talk you into the lighter-cost option when it genuinely fits than sell you hardware you do not need.
One more thing worth knowing: copying a key does not change who has access. If you only need spares of a key that is already under your control, that is a key duplication job. After a move or a tenant leaves, rekey first, then make copies of the new key.
Rekeying in Winnetka: tract homes, apartments and the commercial strips
Winnetka, ZIP code 91306, is a compact, working- and middle-class neighborhood, and most of the hardware we see here is single-family or small multifamily. Postwar 1950s stucco tract homes on modest lots make up much of it. Houses in the Runnymede Park area and the Quimby Park area have had decades for keys to scatter, so rekeying a 1950s tract home at owner or tenant turnover is one of the most common reasons to call. A house that old has often seen several owners and renters, and nobody can say how many keys are out there.
Apartment buildings line stretches of Sherman Way, Roscoe Boulevard and Vanowen Street, and that changes the picture. In those buildings, an apartment lock rekey after a resident leaves is routine, and many have security screen doors and shared mailbox banks, which are separate locks from the unit door. A door rekey will not touch the mailbox, so if the previous resident also had a mailbox key, that is a different job. See mailbox lock replacement for older multifamily buildings. And if the problem is that you are standing outside without a key rather than changing keys on purpose, that is an apartment lockout call, not a rekey.
Winnetka sits in the central-west Valley, where hot, dry summers swell and shrink wood doors and frames season after season. The effect on locks is modest, but in older homes it shows up as sticking latches and strikes that no longer line up the way they once did. We check this on every rekey, because a freshly rekeyed lock on a door that drags is still frustrating. If the latch or strike needs adjusting, we tell you what we found before doing anything extra.
Along the Saticoy Street and Vanowen Street commercial strips, small storefront doors are a regular part of our local work too. Whether you are near the Winnetka Recreation Center at Roscoe Boulevard and Winnetka Avenue, over by the Winnetka Avenue corridor near Pierce College, or anywhere around the Sherman Way and Winnetka Avenue intersection, the process is the same.
To be straight about distance: our storefront is at 10740 Wilshire Blvd in Westwood, about 20 miles from Winnetka. We do not have a Winnetka shop. We serve the area with mobile vans, and when you call we will tell you when we can reach you.

Call (213) 577-1366Do you handle commercial and business lock rekey?
Yes. A commercial lock rekey follows the same logic as a house: you change who holds working keys without replacing the door hardware. The usual triggers for a business lock rekey are an employee leaving, a former manager who still has keys, a new tenant taking over a unit, or a set of keys that simply cannot be accounted for anymore.
For small storefronts, we look at the front door, back door and any storeroom or office doors in one visit. If you have several employees with different levels of access, a master key arrangement may fit better than one key for everything. For bigger or more specialized needs, see our commercial locksmith page. Rekeying is the starting point, not the whole story, and we will tell you if your doors need something more.
Tenant turnover rekey for landlords and small multifamily owners
If you own a few units or a small building, rekeying between tenants is the single most useful habit you can build. It is quick compared with the risk of leaving old keys live, and it protects both the next resident and you. A consistent routine also keeps your records simple: you know which key was cut for which resident and when.
Common sense applies. Rekey after every move-out, not just the ones that ended badly. Keep a written record of how many keys were issued. If you want a single key for your own access across several units, ask about keyed-alike or master key options before the work is done, not after. For recurring turnover work, our locksmith for landlords page explains how we work with property owners.
If you are a tenant, check your lease before calling. Most landlords expect to control lock changes, and we will want to confirm who has the authority to approve work on the door.
Why call Wilshire Lock & Key for a rekey?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties. We are one company with a storefront at 10740 Wilshire Blvd, Los Angeles, CA 90024 and mobile service vans. When you call (213) 577-1366, you are reaching us, not a dispatch middleman who hands the job to whoever is closest. David, the owner and lead technician, oversees how the work gets done.
The phone is answered 24 hours a day, 7 days a week, year-round. A rekey is not always an emergency, but sometimes it is: you lost your keys at night, or a tenant left without returning them, or you bought a house and do not want to sleep with unknown keys floating around.
One more piece of advice that applies to any locksmith: California requires locksmith companies to hold a BSIS LCO license. Ask any company for it, us included, and verify it with the state before work begins. A real company will answer without hesitation.
Frequently asked questions
How long does it take to rekey a house?
It depends on how many locks you have and what shape they are in. A single door is a short visit. A whole house with several knobs and deadbolts takes longer, especially if you want everything keyed-alike. We can give you a better idea once we know the number and type of locks.
Do the old keys stop working after a rekey?
Yes. That is the whole point. After repinning, the old keys will no longer turn the lock, and we test that before we leave. Only the new keys cut for the new combination will work.
Is rekeying cheaper than replacing the locks?
When the hardware is in good condition, rekeying is usually the more economical route because you keep the locks you already own. If the locks are worn or damaged, replacement may make more sense, and we will tell you that honestly instead of rekeying something that is failing.
Can you rekey all the locks in my house to one key?
In most cases, yes. Matching locks to one key is called keyed-alike. It works best when the locks share a compatible keyway. If you have a mix of brands, a cylinder or two may need to be swapped, and we explain that before starting.
I rent my apartment. Can I have the locks rekeyed myself?
Check your lease and talk to your landlord first. Most landlords control lock changes, and we will want to confirm that whoever is approving the work has the authority to do so. If you are the owner or manager, we can handle apartment lock rekeys directly.
Can you rekey locks late at night or on a holiday?
Our phone is answered 24 hours a day, 7 days a week, year-round. Rekeying after hours is possible when the situation calls for it, such as lost keys or a security concern. Late-night and holiday work may be priced differently than a weekday visit, and we explain that on the phone.
What if my lock cannot be rekeyed?
Some locks are too worn or damaged, and some restricted keyway systems depend on the manufacturer. If we find one, we tell you what the options are, which may include repair or replacement. We confirm this in person at the door before any work begins.
Does rekeying my door also change my mailbox lock?
No. Mailbox locks are separate, and in older multifamily buildings with shared mailbox banks they are a different job from rekeying the unit door. Tell us when you call if the mailbox is part of what needs attention.
