What does lock rekeying actually do?
Rekeying is the simplest way to take control of who can open your door. Inside a standard pin tumbler lock is a row of small pins that line up only when the right key is inserted. When we rekey a lock, we remove the cylinder, swap out the pins for a new combination, and cut new keys to match. The lock body, the deadbolt, the handle and the strike plate all stay exactly where they are. The only thing that changes is which keys work.
That is why rekey service is so often the sensible first step after something changes in your life. The old keys, whether they sit in a former roommate's drawer, on a contractor's ring or at the bottom of a lost bag, become useless the moment the work is done. You walk away with fresh keys and the same doors you already have.
One more benefit people appreciate: we can rekey several locks to the same key. If you have a front door, a back door, a side gate and a garage entry, you can carry one key instead of four. We call that rekeying all house locks to match, and it is one of the most common requests we get.
When should you rekey locks in El Segundo?
Most people call us because of a specific event, not because of a general plan. These are the situations where rekeying makes the most sense:
- Rekeying locks after moving: you cannot know how many copies of the previous keys exist, so changing them is the only way to know exactly who has access.
- Rekeying locks after buying a house: previous owners, agents, contractors, cleaners and neighbors may all have held keys over the years.
- Rekeying locks after a tenant moves out: a clean reset between tenants keeps one person's old key from opening the next person's home.
- Rekeying locks after losing keys: if your keys are gone and you cannot rule out that someone found them, new keys are cheap peace of mind compared with the alternative.
- After a breakup, a falling-out with a roommate, or a change in who should have access: the lock still works, but the trust has changed.
- After a break-in attempt where the lock itself is undamaged: if keys were taken, the hardware is fine but the access has to be reset.
How we rekey your locks, step by step
Rekeying is quick work for a trained locksmith, but it is still precise work. Here is how a typical visit goes, whether we come to you with a mobile van or you stop by our Westwood storefront at 10740 Wilshire Blvd with a cylinder or two in hand.
- You call (213) 577-1366, day or night, and tell us how many locks are involved and what kind they are: entry knobs, deadbolts, a garage side door, a gate padlock, or a mix.
- We ask a few questions about the brand and condition of the hardware so we arrive with the right pins, key blanks and tools.
- On site, we confirm that each lock is in good working order. A worn or damaged lock is not a good candidate for rekeying, and we will tell you so before we start.
- We remove each cylinder, replace the pin combination, and cut new keys to match your chosen keying, either one key for everything or separate keys where you want them.
- We reinstall the cylinders, then test every lock with the new keys and confirm that the old keys no longer turn.
- We hand you the new keys, explain what we did, and tell you plainly if anything else we noticed, such as a loose strike plate or a sticking latch, deserves attention.

Call (213) 577-1366Should you rekey or replace the lock?
Rekeying is not always the right answer, and we would rather tell you that than do work you do not need. The deciding factor is usually the condition and quality of the lock itself.
Rekey when the hardware is sound, the finish is acceptable and the lock operates smoothly. In that case you keep what you have and only the key combination changes. Replace when the lock is worn out, the latch drags, the cylinder is damaged or the finish is falling apart. If a lock is already failing, putting new pins in it just gives you new keys for an old problem. In those cases our lock replacement service makes more sense.
There is also a third path. If you want a different style of hardware, or a higher level of pick and drill resistance, changing the locks outright lets you upgrade at the same time. We will go through the three options with you at the door and let you choose.
How much does lock rekeying cost in El Segundo?
We do not quote numbers on a web page, because an honest price depends on the job in front of us. What we can do is explain exactly what moves the cost up or down, so nothing surprises you.
In most cases rekeying is the more economical route compared with replacing every lock, because you are paying for labor and a few small parts rather than new hardware. These are the factors that shape the final figure:
- The number of locks or cylinders: each one has to be removed, repinned and tested.
- The type and brand of lock: some are quick to rekey, while others use proprietary or restricted keyways that take longer or require special parts.
- Whether you want everything keyed alike, which can mean more careful work than keying each lock separately.
- The number of new keys you want cut.
- Condition: a lock that is stiff, corroded or damaged may need repair or replacement, which is a different job from a simple rekey.
- The time of day: a late-night or holiday call involves different logistics than a scheduled daytime visit.
- Travel: we serve 140 cities across Los Angeles and Ventura counties, and El Segundo sits roughly 14 miles from our base.
Rekeying across El Segundo: bungalows, Main Street and the office campuses
El Segundo is really two towns that happen to share a ZIP code, 90245. The residential west side is a compact grid of 1920s to 1950s bungalows, Spanish-style homes and low-rise apartments. The east side is almost entirely aerospace, media and office campuses with very little housing. Each side asks something different of a locksmith.
In the westside residential grid, many single-family homes still have original wood doors and older hardware. That is good news for rekeying in one respect: a well-made older lock often has plenty of life left, and rekeying lets an owner who just bought a house reset access without drilling into a historic-looking door. It is also where we get calls about apartment lock rekeying. A low-rise building changing tenants needs the unit's locks reset so the previous resident's key goes dead, and when someone is locked out of a unit in that grid, our apartment lockout service covers the emergency side.
The beach sits directly west of that grid, and the persistent marine layer and salt air are hard on exterior hardware. Locks, hinges and gate hardware on homes closest to the water corrode faster than the same parts inland. When we rekey an exterior lock in that area, we look at the cylinder first. If salt has made the key turn gritty, or the latch is sluggish, rekeying on its own would only put new keys into a failing lock, and we will recommend replacing it instead. If the lock is still clean and smooth, rekeying is the sensible, lighter-cost choice.
Downtown El Segundo along Main Street has storefronts and small businesses where staff turnover is a normal part of life. A business lock rekey after a manager leaves, or after a set of shop keys goes missing, resets access without changing the door hardware that customers see. In Smoky Hollow, converted creative offices often change tenants or hands, and a lock change when a new team takes over is a routine reason to call. Office space in the Continental Park district or at Campus El Segundo usually involves larger systems, which we cover below.

Call (213) 577-1366Commercial rekey and tenant turnover
A commercial lock rekey follows the same logic as a home rekey, but the stakes and the scale are bigger. Offices and shops often have more doors, more people with keys and a stricter need to know exactly who can get in. Whenever an employee leaves, a lease turns over or a set of keys cannot be accounted for, rekeying the affected doors is the standard fix.
Tenant turnover rekey is one of the clearest uses of the service in El Segundo, whether the building is a low-rise apartment on the west side or a converted office in Smoky Hollow. Between occupants, the lock should be reset so that the prior tenant's keys, and any copies made along the way, stop working. Property owners and managers with several units benefit from doing it the same way every time, and our locksmith for landlords service is built around that routine.
Larger commercial properties often need more than a simple rekey. A building with many employees or departments may want a master key system, where individual keys open only certain doors and a higher-level key opens a set of them. For broader commercial work, from door hardware to access needs, see our commercial locksmith page. We will tell you honestly whether your property needs a simple rekey or a more structured system.

What to check before hiring any locksmith
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS locksmith company license, or LCO. Whoever you hire, for rekeying or anything else, ask for their license number and write it down. A legitimate company will give it to you without hesitation.
A few other habits will protect you. Ask what the job includes before work begins. Be cautious of anyone who cannot explain what affects the cost, or who tells you a lock must be drilled and replaced when a rekey might do. And if a locksmith will not describe how they plan to rekey your locks, that is worth noticing.
If you also need extra copies once the rekey is done, our key duplication service can handle that. For people who want stronger protection at the same time, a look at high-security locks is worth a conversation, because some restricted keyways make unauthorized copies much harder to get.
Frequently asked questions
What is the difference between rekeying and changing locks?
Rekeying changes the internal pins and the keys, but keeps the same lock hardware on your door. Changing locks means putting different hardware in place. Rekeying is usually the more economical route when your locks are in good shape, while replacement makes sense when they are worn, damaged or you want an upgrade.
Do I need to rekey my locks after buying a house in El Segundo?
We recommend it. You cannot know how many copies of the previous keys exist or who still holds them. Rekeying locks after buying a house means only the keys you receive from us will work, and it usually takes less effort than replacing every lock.
Can you rekey all the locks in my house to one key?
Yes, in most cases. If your locks are compatible, we can rekey all house locks to match, so one key opens the front door, back door, garage entry and more. Some specialty or restricted locks may not match others, and we will tell you when we see that.
Can older locks on 1920s to 1950s homes be rekeyed?
Often yes. Many older locks have plenty of service life left, and rekeying lets you keep original-looking hardware. We check the cylinder and latch first. If a lock is badly worn or damaged, we will explain why replacing it is a better choice.
Will salt air near the beach affect whether my lock can be rekeyed?
It can. Marine layer and salt air corrode exterior locks, hinges and gate hardware, especially on west-side homes closest to the water. If the cylinder is gritty, stiff or visibly corroded, rekeying alone will not fix the underlying problem, so we may recommend replacement. If it is clean and smooth, rekeying works fine.
Do you rekey commercial locks and office doors?
Yes. We handle commercial rekey and business lock rekey for storefronts, converted offices and larger buildings. If your property needs a structured system with different access levels, we will talk through master keying with you rather than forcing a simple rekey where it does not fit.
How do I handle rekeying between tenants?
A tenant turnover rekey should happen after the old tenant returns their keys and before the new one moves in. We reset the unit's locks so the previous keys no longer work. If you manage several units, we can keep the process consistent across them.
Can you rekey locks if I lost my keys and cannot get inside?
If you are locked out, the first job is getting you in, and then we can rekey so the lost keys stop working. Call (213) 577-1366 at any hour. For emergencies, our team can also help with lockouts at the same visit.
Does rekeying work on any lock?
It works on most standard pin tumbler locks, but not every lock. Some are damaged, some use unusual keyways, and some are not designed to be rekeyed. We check on site and tell you honestly before doing any work.
How do I know a locksmith in El Segundo is legitimate?
Ask for their California BSIS locksmith company (LCO) license number and write it down. Also ask them to explain the work and what affects the cost before they start. A real locksmith company will be comfortable with both questions.
