What does lock rekeying actually do?

A lock rekey changes the inside of a lock so that a different key operates it. Most house, apartment and small-business locks are pin tumbler cylinders. Inside each cylinder sits a stack of small pins at exact heights. Your key lifts those pins to a clean line and the cylinder turns. When we rekey, we take the cylinder apart, install a new pin combination, and cut keys to match it. The old key still slides into the lock, but it no longer turns it.

The point of the job is that you keep the hardware you already own. The deadbolt, the knob, the handle set, the finish and the look of the door all stay the same. Only the question of who can open it changes. For many households and small businesses that makes rekeying the usually more economical route to getting control of access back.

Rekeying is a different job from replacing a lock. Replacement means new hardware. Rekeying means the same hardware with a new key code. Both have their place, and later on this page we explain how we decide between them. If you simply want to know whether your locks can be rekeyed, call (213) 577-1366 and describe what is on your doors.

When should you rekey your locks?

The honest answer is: any time you cannot say with confidence who holds a working key. Keys get copied, handed out, lent to a neighbor and forgotten in a drawer. A rekey resets all of that in one visit. These are the situations that bring most people to us:

  • Rekey locks after moving in. Previous owners, tenants, cleaners, agents and contractors may all still have keys, and you have no way of knowing how many copies exist.
  • Rekey locks after buying a house. A home purchase hands you a set of keys, but not a list of everyone who ever received one. This is one of the most common reasons for a house rekey.
  • Rekey locks after a tenant moves out. Tenant turnover rekey work keeps one resident's keys from opening the next resident's door.
  • Rekey locks after losing keys. If a key is missing and could be traced to your address, changing the lock is more sensible than hoping it stays lost.
  • After a breakup, a roommate leaving, or a falling-out with a former employee or contractor.
  • When you have a drawer full of keys and want every door on the property to work from a single key.

How do we rekey your locks, step by step?

Here is how a typical rekey visit runs, whether it is a single front door or every lock in the house.

  1. You call (213) 577-1366, any hour. Tell us how many locks are involved, the brand if you can read it on the lock, and whether any keys are missing.
  2. We drive out in a mobile van. Our storefront at 10740 Wilshire Blvd in Westwood is our base, and the van carries the pins, cylinders and key-cutting equipment the job needs.
  3. We inspect every lock before touching it. We check that the cylinder can be rekeyed, that the latch retracts smoothly, and that the deadbolt lines up with the strike plate.
  4. We remove each cylinder, replace the pin stack with a new combination, and reassemble it. Some modern locks use a reset method instead of new pins, and we use whichever the lock is designed for.
  5. We cut new keys to the new code, then test every lock with the door open and with it closed. Testing with the door closed matters, because a misaligned bolt can feel fine in your hand and still bind in the frame.
  6. If you want, we set all the locks to one shared key so you carry a single key for the front door, back door and side gate. Tell us before we start so we plan the pins accordingly.
  7. We hand over the new keys and tell you what to do with the old ones. If you need spares, we can cut them on the spot or you can read about key duplication for more detail.

Should you rekey the lock or replace it?

Most of the time a rekey is the right call. But not every lock deserves it, and we would rather say so than rekey something that will fail next month. When we look at a lock we are weighing three things: condition, quality and what you are actually trying to achieve.

If the lock is in good shape and turns smoothly, rekeying keeps your money in the hardware you already have. If it is worn, sticky, loose in the door, or has a bent latch, rekeying will give you new keys in a lock that still does not work well. In that case a lock replacement is the better route.

Be realistic about what a rekey does not do. It does not make a weak lock stronger. A rekeyed builder-grade deadbolt is still a builder-grade deadbolt, and a short strike plate screw is still a short screw. If the goal is stronger hardware as well as new keys, or if you want a whole new look across the house, our change locks service covers that.

  • Rekey when the hardware is sound, the finish is fine, and your only concern is who holds keys.
  • Replace when the lock is worn, damaged, mismatched, or is not up to the level of protection you want.
  • Do both when some doors have good hardware and others do not. We can rekey the good ones and replace the rest, then key everything to match.

What affects the cost of lock rekeying?

We do not quote numbers on a web page, because the honest total depends on your doors, not a flat figure. What we can do is tell you exactly what moves the cost up or down, so there are no surprises when we talk on the phone.

  • How many cylinders are being rekeyed. One deadbolt is a smaller job than every entry door, the garage side door and a gate.
  • The brand and type of lock. Some are straightforward and others need particular parts or tools.
  • The condition of each lock. If a cylinder is worn or damaged, we may recommend replacing that one instead, which changes the scope.
  • Whether you want one key for everything or separate keys per door. Keying alike takes planning but simplifies life afterward.
  • How many keys you need cut, and whether they are standard or restricted blanks.
  • The time of day. Evening, overnight and weekend calls are different from a planned daytime visit, and we are available around the clock.
  • Your location relative to our base. Signal Hill is about 29 miles from our Westwood storefront, and that distance is part of how a visit is scheduled and quoted.
  • Any extra work we find at the door, such as a loose strike or a failing latch, which we will point out and discuss before doing anything.

Rekeying for landlords, apartments and commercial spaces

Rekeying is the backbone of tenant turnover. When a resident leaves, the safest assumption is that their keys went with them, along with any copies. An apartment lock rekey between tenants gives the next occupant a lock nobody else can open, without the cost of new hardware on every unit. If you manage several units, our page on locksmith services for landlords explains how we handle turnover in batches. Check your own lease and local rules about who handles lock changes; that is a legal question we leave to you and your attorney.

Business lock rekey and commercial rekey work follow the same principle with extra layers. Offices, shops and shared buildings usually have more doors and more people holding keys. Staff leave, vendors come and go, and a rekey after a departure is a routine way to tighten up. Many commercial spaces also want a structure where one key opens everything for the owner while employees hold keys to certain doors only. That is a master key system, and it is best planned before the rekey, not after.

For broader commercial hardware needs beyond rekeying, such as closers, exit devices or access control, see our commercial locksmith page. We keep this page focused on the rekey itself.

Rekeying locks around Signal Hill: hilltop homes, Willow Street and the Auto Center

Signal Hill is a small city in Los Angeles County, ZIP code 90755, and it sits above the surrounding coastal plain. Its housing mix is unusual for a rekey conversation. The lower slopes hold modest cottages from the 1920s to the 1940s, dating to the oil boom. The hilltop was redeveloped from the 1980s onward with view-home tracts, townhomes and gated developments, so the housing skews newer than the surrounding Long Beach blocks.

That mix shapes the work. In the hilltop view-home district along Panorama and Skyline drives, a rekey is often a post-purchase job: the home has changed hands, the owners want a clean set of keys, and the hardware is relatively recent and worth keeping. Older cottages on the lower slopes are different. After decades of repairs, a single door can carry a mix of locks from different eras and brands, so we inspect each cylinder rather than assuming a whole house is uniform. Some will rekey cleanly. A few may be better replaced.

Climate matters too. Signal Hill catches marine-layer damp and a steady onshore breeze. Exterior hardware here sees moderate salt exposure, less than beachfront Long Beach but not none. During a rekey we are already handling the cylinder, which is a good moment to check for stiffness or corrosion on exterior deadbolts and side-gate locks, and tell you honestly if one is tired.

The Promontory at Signal Hill and other gated communities are another case. We can rekey the locks on your own doors. Shared gates and entry hardware are often controlled by the community, so tell us what you are trying to change and we will say what falls under a rekey. Gate hardware that is failing, as opposed to simply needing new keys, is covered under gate lock repair.

Along Willow Street and Cherry Avenue, apartments cluster close together, and tenant turnover rekeys are a regular need. If you are locked out of one of those units rather than needing new keys, our apartment lockout page is the right place to start.

The Signal Hill Auto Center district on Cherry Avenue is a commercial rekey scenario of its own, with dealership offices, sales areas and back rooms that may each need a different level of access. The Spring Street industrial corridor adds units with their own doors, roll-ups and side entries. For both, we plan which doors share a key and which do not before cutting anything. If you are in the area near California Heights on the Long Beach side, we can cover that as well.

Why call Wilshire Lock & Key for a rekey?

We have been in business since 1987, and rekeying is among the oldest and most routine jobs in this trade. It is also a job where small mistakes show up later as a key that sticks or a bolt that binds, so experience is worth something here.

We are one company. You call (213) 577-1366 and reach us, not a call center that passes your address to whoever answers an online dispatch. Our storefront at 10740 Wilshire Blvd and our mobile vans work together, and we serve 140 cities across Los Angeles and Ventura counties, Signal Hill among them. Phones are answered 24 hours a day, seven days a week, all year.

David owns the company and is our lead technician, and he oversees how the work is done. That means the standards for testing every lock and explaining your options are set by the person whose name is on the business, not by a commission schedule.

What should you ask any locksmith before they start?

California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as BSIS, called an LCO license. Ask any locksmith company for its license number before work begins, and compare it with the state's records. A reputable company will not mind the question.

Also ask what the total will include, whether the locks will be rekeyed or replaced, how many keys come with the work, and whether the technician will test each lock afterward. Be cautious of anyone who cannot tell you what a visit involves before arriving.

Frequently asked questions

Will rekeying make my old keys stop working?

Yes. After a rekey, the old key can still enter the lock but will not turn it. Only the new keys we cut will operate it. That is the whole purpose of the service.

Can you rekey all house locks to one key?

Yes, in most cases. We can rekey the front door, back door, garage entry and others so that a single key works on all of them. Tell us before we start so we plan the pin combinations. Some specialty locks may not be compatible, and we will tell you if that applies.

Do I need to be home during the rekey?

Someone with authority over the property should be there, or you should arrange access with us in advance. We need to test every lock with the door open and closed, and you will want to receive the new keys directly.

Is rekeying safer than replacing my locks?

Not necessarily. A rekey changes who holds working keys, but it does not make the hardware stronger. If your locks are in good shape, rekeying is usually the more economical route. If they are worn or low-grade, replacement may serve you better, and we will say so after inspecting them.

Can you rekey a lock if I have lost every key?

Usually yes. If you cannot get in, we deal with that first, then rekey the lock so the lost keys are useless. If we cannot rekey a particular lock because of its condition or type, we will explain the alternatives.

Can you rekey locks in the gated Promontory area?

We can rekey the locks on your own doors. Shared gates and entry hardware are often managed by the community or its association, so check what you are allowed to change and tell us what you need. We can then say what a rekey covers.

Do you rekey commercial locks, such as at the Signal Hill Auto Center?

Yes. We handle commercial and business lock rekeying for offices, shops, dealerships and industrial units. For multi-door buildings we usually plan who needs access to which doors first, which can lead to a master key system rather than one shared key.

How do I know your technician is legitimate?

Ask for the company's BSIS LCO license number, which California requires of locksmith companies, and ask who is coming to your door. Call (213) 577-1366 and we will tell you what to expect before anyone is dispatched.
