What does it mean to rekey locks?
Rekeying changes what a lock responds to without changing the lock itself. Inside a standard pin-tumbler cylinder, a set of small pins sits at specific heights. The right key lifts each pin to the shear line and the cylinder turns. When we rekey, we take the cylinder apart, fit pins sized for a new key, and cut keys to match. The old key still slides into the lock, but it no longer turns anything.
For a Bellflower homeowner or renter, that means the hardware you already picked stays on the door: the deadbolt, the knob, the handle set. Only the people holding the old keys lose access. When the hardware is in decent shape, rekeying is usually the more economical route compared with replacing locks, and it is the option we suggest first.
Rekeying also lets us put several locks on one key. If you carry separate keys for the front door, the back door and a side gate, we can pin them alike so one key works for all of them. That is what most people mean when they ask us to rekey all house locks. It is a different job from a lockout or a lock replacement, and the right fit depends on what you are trying to fix.
When should you rekey your locks?
The rule of thumb is simple: rekey whenever you cannot say for certain who holds a working key. Keys get copied, handed out and forgotten, and nothing on a key tells you how many duplicates are out there. These are the situations where we rekey most often:
- Rekey locks after moving in. You cannot know how many copies the last occupant made, or who they gave one to.
- Rekey locks after buying a house. Previous owners, agents, contractors, cleaners and relatives may all have had a key at some point. A rekey on closing week starts you with a clean list.
- Rekey locks after a tenant moves out. For a landlord, tenant turnover rekey is the ordinary way to make sure the next tenant holds the only set.
- Rekey locks after losing keys. A lost key with an address attached, or a wallet that was stolen, is worth acting on. Once the locks are rekeyed, that lost key is just a piece of brass.
- After a falling out. A roommate who left on bad terms, a former partner, a contractor whose job has ended, or a caretaker you no longer use.
- To cut down on keys. If your household juggles four keys for four doors, pinning them alike makes daily life simpler.

Call (213) 577-1366How we rekey your locks, step by step
A rekey is a short, orderly job when the locks are in good condition. Here is how it goes from the first call to the last test.
- You call (213) 577-1366. Tell us how many locks need rekeying, what kind they are (knob, deadbolt, handle set, padlock), and why you want them changed. If you know the brand, mention it. We will explain what affects the cost for your particular job before anyone drives out.
- A mobile van comes to your address. We will ask you to show that you live there or manage the property, because we are about to change who can get in, and that is a fair question for any locksmith to ask.
- We look at each lock before touching it. The key should turn smoothly, the latch should retract fully, and the cylinder should be a standard type we can re-pin. If something is worn or damaged, we tell you now, not halfway through.
- We remove the cylinders, replace the pins with a new combination, and cut new keys. Where it makes sense, we pin several doors to the same key.
- We test every lock with the new key and again with an old key to confirm the old one no longer turns. We also check that the bolt throws and retracts cleanly into the strike.
- We hand you the new keys and explain how to get more copies later. If you want spares, our key duplication service covers that, and we suggest copying only from the new key and only when you need to.
When is rekeying not the right fix?
We would rather tell you straight than rekey a lock that should not be rekeyed. Rekeying only changes the inside of a cylinder. It does nothing for hardware that is failing, weak or mismatched to the door.
If a deadbolt is loose in the door, the latch sticks, the cylinder is badly worn or the lock has been damaged by a forced entry, you are better off with a lock replacement. If you want a stronger lock on a door that currently has only a knob, a new deadbolt is an upgrade, and our deadbolt installation page explains how we handle that. If you want to swap every lock at once for a new look or matching finish, that is a full lock change rather than a rekey.
Older wood doors deserve a mention here. On a damp winter morning in this part of the coastal plain, an older wood door or frame can swell slightly, and a bolt that slid easily in summer can start to bind. People sometimes blame the key or the cylinder when the real issue is alignment. We check for that during inspection, because re-pinning a perfectly good cylinder will not cure a door that is rubbing the strike.
Some high-security cylinders are also controlled products with restricted key blanks. Those follow a different process, and in some cases the manufacturer or dealer has to be involved. If you think you have one, tell us on the phone and we will confirm what is possible before we come out.

Call (213) 577-1366What affects the cost of a lock rekey?
We do not publish numbers on a web page, because the honest answer depends on your doors. What we can do is tell you exactly what moves the cost up or down, so the figure you are quoted on the phone makes sense.
Most of the variation comes from a handful of factors:
- How many cylinders you have. A single door is a different job from a house with a front door, back door, garage entry and side gate.
- The lock type and brand. Common residential brands are straightforward. Specialty or restricted cylinders can need extra parts or extra steps.
- How many keys you want cut, and whether you want everything keyed alike.
- The condition of the hardware. Worn cylinders take longer to work on, and some are not worth re-pinning.
- Whether it is a home, an apartment, a rear unit or a commercial space. Commercial rekeys can involve multiple keyways, key control and more doors.
- When you need us. After-hours and overnight visits are part of what we do 24 hours a day, and timing can affect the quote.
- Travel. Our storefront is in Westwood and Bellflower is roughly 25 miles from our base, so we come by mobile van and factor that into the job.
How does rekeying work around Bellflower and the 90706 ZIP code?
Bellflower grew out of a dairy and farm town, and much of its housing is made up of 1940s and 1950s cottages and bungalows. What stands out is the number of rear units, duplexes and front-house/back-house lots. That makes rekey jobs here different from a typical single-family street, because one address can have several entry doors, several occupants and several sets of keys.
A front-house/back-house lot is a good example. When the property changes hands, or when one of the units turns over, the owner often wants every door on the lot rekeyed, with each unit on its own key and perhaps a separate key for shared gates and utility doors. We can plan that on the phone: how many doors, which ones should share a key, and which must stay completely separate. In 90706, that kind of multi-door rekey is one of the most natural uses of what we do.
Apartment buildings and mobile home parks raise the renter share in Bellflower, and tenant turnover rekey is a constant need. Around the Artesia Boulevard and Alondra Boulevard corridors, apartment residents sometimes get locked out, and that is a separate situation we cover under apartment lockout. But when the question is whether the last tenant still has a working key, a rekey is the answer. In the mobile home parks, we look at the door hardware first, since some older units need hardware replacement rather than re-pinning.
Homes backing the Bellflower Bike Trail often have side gates and padlocks as the first line of entry. We can rekey compatible padlocks and gate locks so they share a key with the house, which saves carrying a ring of keys. Closer to downtown, the Bellflower Boulevard core has newer mixed-use buildings alongside older storefronts, and shop owners in that stretch regularly ask about commercial rekey, which we cover further down.
Whether you are in the Simms Park area, along Woodruff Avenue, near Rosecrans or Somerset, or on the edge of Lakewood Village in Long Beach, the process is the same. We come to you in a mobile van, check the locks, and rekey on site. Our mobile locksmith service explains how the van setup lets us do most rekeys at your door without taking hardware away.

Call (213) 577-1366Can you handle tenant turnover rekeys for landlords?
Yes, and in a city with a large renter population it is some of the steadiest work we see. When a tenant moves out, most landlords want the locks changed before the next person receives keys. Rekeying does that while keeping the hardware you already own, which is why it is the common choice between tenants.
For a landlord with a duplex or a front-house/back-house property, we can rekey each unit separately and, if you want, set up a key that you keep for emergencies. If you manage several properties, tell us up front. We can talk through whether it is simpler to standardize on one brand of hardware so future turnovers go faster. Our page for locksmith services for landlords covers the wider picture, including how we coordinate with owners and managers.
One practical suggestion: schedule the rekey after the final walkthrough, not before. If the old tenant still has a legitimate reason to enter to collect belongings, you do not want to rekey twice. Once the unit is empty and handed back, one visit is all it takes.
Do you rekey business and commercial locks?
We do. A business lock rekey has a few differences from a house rekey. Shops and offices often have more doors, a rear entrance, a storage room, sometimes an office with its own key. When an employee leaves or a lease changes hands, rekeying is a way to cut off old keys without replacing every piece of door hardware.
Commercial rekey can also be used to set up a hierarchy, where each door has its own key and a single higher-level key opens several. That is the idea behind a master key system, and it is worth planning before you rekey, not afterward. For shops along the Bellflower Boulevard corridor, we start by finding out how many people need keys and to which doors, then work out the least complicated layout. Our commercial locksmith page describes the wider work we do for businesses.
If a storefront lock is failing, loose or damaged, rekeying will not solve that. We will check the door hardware first and be honest about whether you need repair or replacement, not just a new key.
Why call Wilshire Lock & Key for a rekey?
We have been in business since 1987, working from a storefront at 10740 Wilshire Blvd in Westwood, with mobile service vans that reach 140 cities across Los Angeles and Ventura counties. That includes Bellflower. When you call (213) 577-1366, you reach the same company that sends the van. There is no dispatch middleman passing your job to whoever is free.
David, the owner and lead technician, oversees the work. Rekeying looks simple, but small errors, such as a pin set cut a hair wrong or a cylinder reassembled badly, can leave a lock that sticks or fails months later. Every lock gets tested before we leave.
One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before you let them work on your doors. That applies to us as it does to anyone else, and you are right to ask.
Our phone line is answered 24 hours a day, seven days a week, all year. If you are standing at a front door at night after losing your keys, call us. If you are planning a rekey for after closing on a house, call us during the day and we can schedule it. For other options, see our Bellflower overview or the contact page.
Frequently asked questions
What is the difference between rekeying and changing locks?
Rekeying keeps the existing lock hardware and changes the internal pins and the key. Changing or replacing locks means removing the hardware and installing new locks. Rekeying is usually the more economical route when the locks are in good shape. Replacement makes sense when they are worn, damaged or you want a different level of security.
Should I rekey locks after buying a house in Bellflower?
Yes, we recommend it. You do not know how many copies of the old keys exist or who has them, including previous owners, agents and contractors. In a place with duplexes and front-house/back-house lots, check every entry door on the property, including rear units, side gates and any shared doors.
Can you rekey all the locks in my house to one key?
Usually yes, if the locks are a compatible type. We can pin your front door, back door, deadbolts and many padlocks to the same key. Some specialty or restricted locks may not work with others, so tell us what you have when you call and we will confirm what can be keyed alike.
How long does a rekey take?
It depends on how many locks there are and their condition. A single door goes quickly, while a house or a multi-unit lot takes longer. We would rather give you an honest idea based on your actual doors than a promised number. Call (213) 577-1366 and describe what you have.
Will my old key still work after a rekey?
No. That is the point. After re-pinning, the old key may still go into the lock but will not turn it. We test each lock with an old key before we leave to confirm that it no longer works.
Do I need to be home when you rekey the locks?
Someone with authority over the property should be there at the start, to show access and confirm what should be changed. Landlords and managers can arrange access for between-tenant rekeys. We will go over the details when you call.
Can you rekey a commercial or storefront lock?
Yes. We handle business lock rekey, including shops with several doors and keys. We can also help plan keyed-alike or master-key layouts. If the hardware is damaged, we will tell you whether repair or replacement is the better route instead of rekeying.
Can all locks be rekeyed?
Most standard residential and commercial pin-tumbler locks can be. Some are worn out, some are damaged, and some high-security cylinders are restricted and need different handling. We inspect each lock first and tell you honestly if rekeying makes sense or if replacement would work better.
How do I find out if a locksmith is legitimate?
California requires locksmith companies to hold a BSIS LCO license. Ask for it before work starts, and be cautious with anyone who will not provide it or who cannot say what drives the cost of the job. You can also ask who will actually be doing the work and where the company is based.
