What does it mean to rekey locks?
Rekeying is the simplest way to make a lock stop trusting old keys. Inside every pin-tumbler cylinder is a set of small pins that line up only when the right key is inserted. To rekey a lock, we take the cylinder apart, replace those pins with a new combination, and cut new keys to match. The lock stays on your door. The hardware you picked, the finish, the handle, the deadbolt all stay put. What changes is which keys open it.
That is why rekeying is usually the more economical route when your concern is who holds a key rather than the condition of the lock. Someone you no longer want in the house, a set of keys that walked off with a former tenant, or a ring you dropped somewhere unknown all have the same fix: the old key becomes a piece of metal that does nothing.
Rekeying is not a repair and it is not an upgrade. It will not make a worn lock tighter or a flimsy deadbolt stronger. We will be straight with you about that during the visit, because the goal is to match the work to the real problem, not to sell more than you need.
When should you rekey your locks in Lake Balboa?
Most of the calls we get for house rekey and home lock rekey come from a handful of situations. If you recognize yours below, rekeying is almost certainly the right conversation to have.
- After moving in or buying a house: you have no idea how many copies the previous owner, their relatives, a contractor, or a cleaning service kept. Rekeying all house locks resets that count to the keys in your hand.
- After a tenant moves out: a lock rekey between tenants is standard practice, since the departing tenant may have copied keys, and you cannot know.
- After losing keys: if a key vanished with an address attached to it, or you simply cannot account for it, rekeying closes the question.
- After a breakup, a falling-out with a roommate, or ending an arrangement with a caregiver, house sitter, or contractor.
- When you want every door on one key: front, back, side gate, and garage entry can often be keyed alike so you carry one key instead of four.
- After a break-in or attempted entry, once any damage is dealt with, so you are not relying on keys that may have been copied.
How does a rekey visit work, step by step?
Whether you call us for a one-door apartment lock rekey or a full set of rekey door locks on a house, the sequence is the same. We come to you in one of our mobile vans, or you can bring cylinders to our Westwood storefront at 10740 Wilshire Blvd when that suits you better.
- You call (213) 577-1366 and tell us what happened: new home, tenant turnover, lost keys, or something else. We ask how many locks, what kind they are, and whether any are sticking or damaged.
- We inspect each lock on site. Before touching anything we confirm the cylinder can actually be rekeyed and is in good enough shape to be worth keeping.
- We remove the cylinder, replace the pins, and cut new keys. For most standard locks this is quick, hands-on bench work.
- We test every lock with the new key and with an old key to confirm the old one no longer turns. Testing both is the point of the whole job.
- We check the door itself: latch alignment, strike plate, and how the bolt throws. A lock that is rekeyed but binds in a swollen door will frustrate you anyway.
- You get the new keys, and we explain what to do with spares and whether you should add copies now rather than later.

Call (213) 577-1366What affects the cost of rekeying locks?
We do not quote numbers on a web page, because an honest price depends on your actual locks. Here is what moves the cost up or down, so you can see why a phone conversation and a quick look at the hardware matter.
The biggest factor is how many cylinders are involved. Rekeying one apartment door is a smaller job than rekeying every entry point on a house. Next is the type of lock. Common residential knob and deadbolt sets are straightforward. Higher-security cylinders, restricted keyways, and some commercial hardware take more care, and sometimes special key blanks.
Condition matters too. A lock in good shape rekeys cleanly. A worn or damaged cylinder may cost more to coax through a rekey, and sometimes the lighter-cost option is to replace the lock instead. We will tell you when that crossover happens.
Other factors: whether you want all locks keyed alike, how many keys you need cut, whether you come to the storefront or we travel to you, and what time of day you need service. Because we answer 24/7, after-hours calls are possible, and timing can be part of the cost conversation. When you call, we explain these factors in plain terms before any work starts.
Rekey or replace: how do you decide?
Rekeying is not always the answer, and a good locksmith says so. Here is how we think about it.
Rekey when the lock itself is sound, you like the hardware, and the issue is key control. This is the case for most tenant changes and most home purchases.
Replace when the lock is worn out, damaged, loose in the door, or simply too old to trust. If you want a different style or stronger hardware, our lock change service and lock replacement work cover that. Replace also if you want to move to keypad or app-controlled entry, which is a separate job from rekeying; see smart lock installation.
Some very old or unusual cylinders cannot be rekeyed cleanly, or parts for them are no longer made. If that is what is on your door, we will explain what we found and offer the practical alternatives. We do not push a replacement when a rekey will do the job.
How does tenant turnover rekey work for landlords and managers?
If you own or manage rental units, rekeying between tenants is one of the most sensible routine steps you can take. A tenant who moves out may keep keys, may have given copies to friends or family, or may simply have lost track of them. The next tenant is entitled to a door that only they and you control, and you are better protected when you can show locks were changed at turnover.
For tenant turnover rekey, we can work through a building door by door or unit by unit. Many owners ask us to key entry doors for each unit differently while keeping shared areas on one controlled key. If you manage several units, a consistent system saves time at every move-out. Our page for locksmith services for landlords describes how we handle ongoing work like this.
One practical note for apartments: always rekey the unit entry, any secondary deadbolt, and any security screen door lock, and think about mailbox locks. Mailbox keys are the ones most often forgotten, and a former tenant holding one can still reach the mail.

Call (213) 577-1366What about commercial and business lock rekey?
Businesses rekey for the same reasons homes do, with more at stake. An employee leaves, a manager departs, a vendor no longer needs access, or keys cannot be accounted for. A commercial rekey changes who can get in without ripping out your hardware.
Commercial doors often use heavier cylinders, restricted keys, or more than one lock per door, and the work is scoped accordingly. Offices, small shops, and storage rooms may all want different key levels: one key for the owner, a limited key for staff, and nothing for anyone who has left. If your business needs that kind of layered setup, a master key system is built for it, and rekeying is often the first step in getting there.
For a broader view of what we do for workplaces, see our commercial locksmith page. If you are asking about a business lock rekey, tell us the number of doors, the type of hardware, and who currently holds keys, and we will plan around that.
Rekeying in Lake Balboa: postwar homes, apartment corridors, and 91406
Lake Balboa was carved out of Van Nuys as its own named neighborhood in the early 2000s, but the houses are much older than the name. The housing is classic postwar Valley stock: single-story stucco homes from the 1940s and 1950s on modest lots. Original door hardware is still common in homes that have not been updated, which makes rekeying a natural fit here. A house that has changed hands several times across seven decades may have had its keys copied a lot of times, and the original knob or deadbolt may be perfectly serviceable, just not under your control.
Our most typical local rekey is exactly that: original hardware in a postwar tract home off the Balboa Boulevard corridor. We inspect the old cylinders and, where they are sound, rekey them so you keep the look of the house and still start with fresh keys. Where a lock has worn past the point of reliable service, we say so and go over replacement.
Apartment buildings run along the Sherman Way and Victory Boulevard corridors, and the Vanowen Street corridor has its share of multifamily and small commercial addresses as well. In those buildings, rekeying is a turnover task: unit doors, secondary deadbolts, and often the older security screen door and mailbox locks that came with the building. If a mailbox lock is worn, our mailbox lock replacement work picks up where rekeying leaves off.
Lake Balboa sits on the Valley floor beside the Sepulveda Basin. Summers are hot and dry, and the air is somewhat damper near the basin's irrigated parkland and lake. That seasonal swing can leave older wood doors sticking or slightly out of alignment, so when we rekey a door in 91406 we also check how the bolt meets the strike. A freshly rekeyed lock should turn easily with the new key.
On the west side of Van Nuys Airport, small aviation businesses and offices use the same kinds of locks as any workplace, and they are rekeyed when staff or tenants change. We serve the whole neighborhood, including the area around Birmingham Charter High School and the edge of the Sepulveda Basin near Anthony C. Beilenson Park. We are about 13 miles from Lake Balboa at our Westwood base, and our mobile vans cover the trip.

Call (213) 577-1366Why call Wilshire Lock & Key for a rekey?
We have been in business since 1987, and rekeying is one of the oldest, most basic things a locksmith does. We approach it as a craft: check the lock, do the work cleanly, test it, and explain what we did.
Here is what you can count on when you call:
- One company. The person who answers (213) 577-1366 is part of the business that does the work. We do not pass your call to a dispatch middleman who sends whoever is free.
- A real storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, so you can come to us or have us come to you. You can reach out here too.
- David, the owner and lead technician, oversees the work. He has been at this a long time and cares how a job is done.
- We answer 24 hours a day, 7 days a week, year-round, because lockouts and lost keys do not keep office hours. We serve 140 cities across Los Angeles and Ventura counties, Lake Balboa included.
How do you check that a locksmith is legitimate?
California requires locksmith companies to hold a Locksmith Company (LCO) license issued by the Bureau of Security and Investigative Services, known as BSIS. It is reasonable, and smart, to ask any locksmith for that license number before they start. Ask for it on the phone, and expect a straightforward answer.
Beyond that, watch for a few warning signs: a company that will not give a business name, a vague answer about who is coming, pressure to drill or replace a lock that a rekey would fix, or a price that changes once the technician arrives. A good locksmith explains the options and lets you decide.
Frequently asked questions
What is the difference between rekeying and changing locks?
Rekeying keeps your existing lock and changes the pins inside so a new key works and old ones do not. Changing locks means removing the hardware and installing different locks. Rekeying is usually the more economical route when the lock itself is in good condition.
Should I rekey locks after buying a house in Lake Balboa?
Yes, we recommend it. You cannot know how many copies of the old keys exist, and many Lake Balboa homes are postwar houses that have changed hands several times. Rekeying all house locks means only the keys you receive from us open them.
Can original postwar door hardware be rekeyed?
Often, yes, if the cylinder is in sound condition. Some very old or worn pieces cannot be rekeyed cleanly, or parts are hard to find. We inspect each one and tell you honestly whether to rekey or replace.
Do you rekey locks after a tenant moves out?
Yes. Tenant turnover rekey is a regular part of our work for owners and managers. We can rekey a single unit or work through several, and we can discuss keying systems if you manage multiple properties.
I lost my keys. Do I need new locks or just a rekey?
In most cases a rekey is enough. It makes the lost keys useless without replacing your hardware. If the lost key was for a car, that is a separate process, and we handle it through our automotive locksmith services.
Can you rekey all my locks to the same key?
Usually, yes. Many sets of locks can be keyed alike, so one key opens the front door, back door, and side entries. It depends on the brands and keyways of your existing locks, and we confirm that when we inspect them.
Do you do commercial rekey for small businesses?
Yes. We rekey office, shop, and other business locks, including setups where different staff need different levels of access. Tell us the number of doors and who holds keys, and we will plan the work around that.
Can I get a rekey at night or on a weekend?
Yes. We answer the phone 24 hours a day, 7 days a week, year-round at (213) 577-1366. Timing can affect the cost, and we explain how when you call.
How do I know your locksmith company is legitimate?
California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for the number before work begins. Also look for a clear business name, a physical address, and a straight explanation of what will be done. Our storefront is at 10740 Wilshire Blvd in Los Angeles.
