What does it mean to rekey locks?
Rekeying is the simplest way to make old keys useless without touching your hardware. Inside a 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 take the cylinder apart, install a different set of pins, and cut a new key to match. The lock looks the same, the deadbolt stays in the same door, and the finish does not change. But every key that used to work, whether it is in a former tenant's drawer, a previous owner's pocket, or at the bottom of the harbor, no longer turns it.
That is why people search for things like rekey locks near me, house rekey, or apartment lock rekey. They usually are not asking for new locks. They are asking for new control over who can get in. A lock rekey is a lighter-touch job than a full replacement, and for doors in decent shape it is usually the more economical route.
It also lets us do something practical: rekey several doors so a single key opens all of them. Front door, patio slider, a gate, and a storage cage can share one key instead of a crowded ring. If you want extra copies afterward, we handle key duplication too.
When should you rekey your locks?
The honest rule is simple: if you cannot account for every key that opens a door, rekey it. In Marina del Rey, where so many people rent, sublet, or buy a unit from someone they have never met, that comes up constantly. These are the situations we see most often.
- Rekey locks after moving: you have no way to know how many copies the last occupant made, or who still has them.
- Rekey locks after buying a house or condo: closing day hands you the keys you were given, not the ones that exist.
- Rekey locks after a tenant moves out: tenant turnover is the most common reason property owners call us for a rekey.
- Rekey locks after losing keys: if the keys had anything on them that points to your address, do not wait to see whether they turn up.
- After a breakup, a roommate leaving, or a falling-out: a key you handed over in good faith is still a key.
- After a contractor, cleaner, house sitter, or former property manager had access: the work is finished, but the key is still out there.

Call (213) 577-1366How does our rekey service work, step by step?
We keep the process plain, because a rekey is not complicated and you should know what is happening at your door.
- Call (213) 577-1366. A real person answers at any hour. Tell us how many locks are involved, the brand if you know it, whether this is a home, apartment, or business, and whether you want the doors keyed alike.
- We talk through your situation and decide whether a rekey makes sense or whether the lock needs more. If it is hard to tell by phone, a photo of the lock helps.
- A technician comes to you in one of our mobile vans. Our storefront is on Wilshire Blvd in Westwood, roughly 9 miles from Marina del Rey.
- On arrival we ask for a reasonable showing that you live there, own the property, or manage it. A locksmith who skips this step is a risk to everyone on the street, including you.
- We inspect each lock. We check that the cylinder turns freely, that the bolt throws cleanly, and that salt, wear, or a previous bad repair has not damaged anything.
- We remove the cylinders, install new pins, and cut the new keys.
- We put everything back and test each key repeatedly. We also try an old key to confirm it no longer works, and we check that the door latches properly into the strike.
- We hand over your keys and tell you which one opens what. If you want extras, now is the time to ask.
Should you rekey or replace the lock?
Rekeying is not always the right answer, and we will say so when it is not. A lock is a good candidate for a rekey when the hardware is solid, the cylinder works smoothly, and the only problem is that the wrong people may hold keys. It is a poor candidate when the lock itself is the problem.
Replace instead of rekeying when the cylinder is badly worn or sticking, when the deadbolt is loose in the door, when the finish has corroded through, or when the lock is a weak, entry-level design and you want more protection. In those cases, changing the locks or a full lock replacement is the better use of your money, because rekeying a failing lock just gives you a failing lock with new keys.
If your concern is more than lost keys, such as pick resistance or drill resistance or restricted key control, ask us about high-security locks. Rekeying makes old keys useless, but it does not make a basic lock harder to defeat.
One more point worth knowing: rekeying changes the key, not the code. If you have a keypad or smart lock, the keyed cylinder underneath can often be rekeyed, but user codes are managed separately in the lock's own settings. We can explain which parts of your lock a rekey does and does not cover.

Call (213) 577-1366What affects the cost of a lock rekey?
We do not quote numbers on a web page because the real figure depends on your doors, and we would rather give you an accurate answer on the phone than a misleading one here. These are the factors that move the cost up or down.
- How many cylinders you have. Each lock is rekeyed individually, so a single deadbolt and a whole unit are different jobs.
- How many keys you need cut, and whether you want everything keyed alike.
- The brand and type of lock. Common residential cylinders are routine; some specialty or high-security cylinders take more work or specific parts.
- The condition of the lock. A clean, smooth cylinder is quick. A corroded or seized one may need extra time or may need replacing.
- Where and when you need us. Service at an unusual hour or at a distant location is priced differently than a scheduled visit nearby.
- Whether other work comes along with it, such as a new strike plate, a loose deadbolt, or a damaged latch.
What should Marina del Rey residents know about rekeying here?
Marina del Rey, ZIP 90292, is a different kind of place to be a locksmith. Almost everything around the harbor is multifamily: big 1960s and 1970s apartment complexes, waterfront condominium towers, and newer rental buildings, with very few single-family homes. So when someone here asks for a rekey, it is usually a unit door in a large building, not a house with a front porch.
In the Via Marina corridor, the Admiralty Way corridor, Mariners Village, and Villa Marina, the typical rekey call is a unit that just changed hands: a new owner, a new tenant, or a roommate who moved out. The unit's own deadbolt and knob are yours to change. The lobby doors, garage gates, and shared mailbox rooms are normally controlled by the building, so we coordinate with management before touching any of those. If the shared mailbox lock is the real problem, that is a separate job, covered under mailbox lock replacement.
Salt air matters more than most people expect. Right on the water, exterior deadbolts, gate latches, hinges, and padlocks corrode noticeably faster than they would inland, and the marine layer keeps hardware damp many mornings. For a rekey, this changes the first question. Before we rekey a balcony-side or exterior-facing lock, we check whether the cylinder still moves freely. If corrosion has set in, rekeying it would be a short-lived fix, and we will tell you plainly that replacement is the better route.
The same logic applies to padlocks and latches on dock gates and dry-storage areas near Fisherman's Village and the harbor. A weather-resistant lock that can be rekeyed lets a boat owner or association change who has access without swapping out the gate hardware. Whether yours can be depends on the lock, so describe it when you call.

Call (213) 577-1366How does tenant turnover rekey work for owners and managers?
If you own a unit in one of the large Marina del Rey complexes and rent it out, the end of a tenancy is the cleanest moment to rekey. The unit is usually empty, you know exactly who had keys, and nobody is inconvenienced. Doing it between tenants, rather than waiting for a complaint, keeps your records simple: new tenant, new key, no unknown copies.
Owners with several units often want a system rather than a pile of unrelated keys. We can rekey a set of doors to a consistent pattern, or set up a master key system so that a manager's key opens many doors while each tenant's key opens only theirs. That takes a little planning up front and saves a lot of confusion later.
For ongoing portfolios, our page on locksmith service for landlords covers how we handle repeat turnovers. A word of caution: lease terms and local rules govern what you can change and when, so check with your property manager or attorney if you are unsure. We do the lock work; we do not give legal advice.
Can you do a commercial or business lock rekey?
Yes. Business lock rekey is a regular part of what we do, and the reasons mirror the residential ones: an employee left, a manager was replaced, a tenant moved out of an office suite, or a key ring went missing. Marina-adjacent commercial buildings and offices often have a mix of suite doors, back-of-house doors, and storage rooms, and each may need to be handled differently.
For a commercial rekey we want to know how many doors, whether you have a keying chart or master key arrangement already, and whether the building owner controls any of the cylinders. If a master system is involved, changing one lock the wrong way can cut off other keys, so we plan before we pull a cylinder. For larger or more complex work, see our commercial locksmith page.
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. Marina del Rey is one of them. David, the owner and lead technician, oversees the work, and the company is a single operation with a Westwood storefront at 10740 Wilshire Blvd and our own mobile service vans. When you call, you are not reaching a dispatch middleman who sells your call to whoever is nearest. You are reaching us, and the phone is answered 24 hours a day, 7 days a week, year-round.
A rekey is a small job where trust matters a great deal, because afterward we are one of the few parties who know how your locks work. So here is a practical tip that applies to any locksmith, including us: California requires locksmith companies to hold a BSIS LCO license, and you should ask to see that license number before anyone works on your door. A reputable company will not mind.
We will also tell you when you do not need us. If a lock is fine and you only want a spare key, we will say so rather than sell you a rekey. If the lock is failing, we will say that too, and explain your options in plain terms.
Frequently asked questions
Will my old keys still work after a rekey?
No. Rekeying changes the pins inside the cylinder, so the old key no longer lines them up and will not turn the lock. We test an old key during the job to confirm that, then give you the new keys.
Can you rekey a lock if I have lost every key?
Usually, yes. We can work from the cylinder itself without an original key. We will ask you to show that you live at the address, own it, or are authorized to manage it before we start.
How long does a lock rekey take?
It depends mostly on how many locks there are and what condition they are in. One door in good shape is a quick job. A whole unit or an office with corroded or unusual hardware takes longer. Tell us the details when you call and we will give you a realistic idea.
Should I rekey after buying a condo in Marina del Rey?
We recommend it. You cannot know how many copies of the old keys exist. Your own unit door is yours to rekey. Lobby doors, garage gates, and shared mailbox rooms are usually controlled by the building, so those go through the association or management.
Can you rekey my mailbox lock?
Sometimes. In many large buildings the mailbox lock belongs to the building or is part of a shared mailbox unit, so ask management first. If the lock is damaged or corroded, replacement is often the better route than a rekey.
Can a smart lock or keypad deadbolt be rekeyed?
The physical keyed cylinder on many of them can be rekeyed. User codes and app access are separate and are changed in the lock's own settings. Tell us the brand and model and we will explain what a rekey would and would not cover.
Is rekeying enough if my deadbolt is corroded from salt air?
Often it is not. A rekey needs the cylinder to move freely. If salt air has corroded the lock, it may bind, wear out quickly, or fail soon after, and replacing it is the better choice. We check the condition before deciding.
Do you rekey business and commercial locks?
Yes. We rekey office, suite, and storage doors, including those that belong to a larger key system. Let us know how many doors you have, whether there is a master key arrangement, and who controls the building's cylinders.
What should I ask a locksmith before hiring one?
Ask for their California BSIS LCO license number, ask whether the person arriving works for the company you called, and ask what affects the final cost. Be cautious of anyone who will not explain their process or who arrives without clear identification.
