What does it mean to rekey locks?
Rekeying is the quiet fix that most people have never heard of until a locksmith mentions it. Every pin-tumbler lock has a cylinder with a set of small pins inside. The pins are cut to match one specific key. When we rekey a lock, we take the cylinder apart, swap the pins for a new combination, and cut a new key to match. The lock stays on your door. The old key still slides into the keyway, but it no longer turns.
That is the whole idea: same hardware, new key, old keys dead. Nobody who held a copy of the previous key, whether a former tenant, a previous owner, a contractor or a friend you gave a spare to years ago, can use it anymore.
People often ask for a house rekey or a home lock rekey when what they actually want is peace of mind. You do not need to know who has a key. You only need to know that the keys in your pocket are the only ones that work. Rekeying gets you there, and it usually costs less than replacing every lock on the property because you keep the hardware you already have.
When should you rekey your locks?
Most of our rekey calls in Canoga Park fall into a handful of situations. If you recognize yours below, rekeying is almost always the right first conversation to have.
A rekey makes sense any time the question is who holds a working key, not whether the lock itself is broken.
- Rekey locks after moving: you cannot know how many copies of the previous occupant's key are floating around.
- Rekey locks after buying a house: sellers, agents, inspectors, cleaners and contractors may all have had keys at some point.
- Rekey locks after a tenant moves out: tenant turnover is the single most common reason landlords call us.
- Rekey locks after losing keys: if the key was lost near home or had an address on it, shutting it out is cheap insurance.
- After a breakup, a falling-out with a roommate, or an employee leaving.
- When you want every door on the property to open with one key instead of a ring of five.
- When a rental, a shop or a shared space has accumulated keys nobody can account for.
How we rekey door locks, step by step
Here is how a typical visit goes, whether it is a single front door or every lock in a house. David has run this shop since 1987 and the method has not changed much, because it works.
- You call (213) 577-1366 and tell us what you have: how many doors, what kind of locks, and why you want the rekey. A person answers, at any hour, and not a call center that passes you along to a stranger.
- We come to you in a mobile van, or you can bring locks to our Westwood storefront at 10740 Wilshire Blvd if that suits you better.
- We look at each lock first. A lock has to be in decent mechanical shape to be rekeyed well, so we check that the cylinder, latch and deadbolt work smoothly and that the brand and keyway can accept a new pin set.
- We remove each cylinder, replace the pins with a new combination, and cut new keys on the spot.
- If you want, we match several locks to one key so the front door, back door and side gate all open the same way.
- We test every lock with the new key and confirm the old key no longer turns. You see this yourself before we pack up.
- You get the new keys, and we tell you plainly if anything we noticed, like a loose strike plate or a worn latch, needs attention separately.

Call (213) 577-1366Rekey, change locks, or replace: which one fits?
Rekeying is the right answer when your hardware is fine and only the keys are the problem. It is not the right answer every time, and we will tell you when it is not.
If the lock is worn out, damaged, or cheap enough that it barely functions, a new lock is the honest recommendation. Our change locks page covers that route, and lock replacement explains when swapping hardware beats rekeying. If you want to move up in security, for example from a builder-grade deadbolt to something that resists picking and drilling, that is a hardware decision, not a rekey, and our high-security locks page explains the difference.
A few cases where rekeying alone will not solve it: a lock that is already broken inside, a lock with a keyway no longer manufactured with parts available, or an electronic lock whose code or credentials are the issue rather than a physical key. In each case we say so before we start, so you are not paying for work that will not fix your actual problem.
How much does lock rekey cost in Canoga Park?
We do not quote numbers on a web page because the real price depends on your actual doors, and anyone who gives a flat figure without asking questions is guessing. What we can do is explain exactly what moves the cost, so you can judge any quote you receive.
Rekeying is usually the more economical route compared with replacing every lock, because you are paying for labor and a small set of parts rather than new hardware on every door.
- The number of locks or cylinders. Each cylinder is rekeyed individually, so a one-door apartment and a five-door house are very different jobs.
- How many new keys you need, and whether you want them keyed alike across all doors.
- The brand and type of lock. Common residential locks are straightforward; specialty or high-security cylinders can require specific parts or restricted key blanks.
- Condition of the hardware. If a lock is stiff or damaged, there may be repair work alongside the rekey.
- Where and when we come. A scheduled daytime visit is different from a late-night call, and travel to your location is part of any mobile service.
- Whether it is a residential job or a business with many doors, which may mean master-key planning on top of the rekey itself.
Rekeying in Canoga Park: tract homes, apartments and shops
Canoga Park began as Owensmouth in 1912, and you can still see that in the early-20th-century bungalows near the Owensmouth historic district. Most of the housing around it, though, is 1940s to 1960s single-family tract homes. Those houses have often changed hands more than once, which is exactly why rekeying 1950s tract homes after move-ins or tenant turnover is such a steady part of the work here. A house in the 91303 or 91304 ZIP code that has gone through two or three owners or renters can easily have a dozen unaccounted-for keys in circulation.
The far West Valley gets long, hot summers with frequent triple-digit stretches, plus dry Santa Ana winds in the fall. Those heat cycles swell and shrink wood doors and frames, which slowly pulls deadbolts and strikes out of alignment in older homes. This matters for rekeying in one specific way: a key that suddenly feels stiff after a rekey is sometimes not the cylinder at all, but a bolt dragging against a shifted strike. We check alignment during the visit, and if the door itself is the problem, we point you to lock repair rather than blaming the new pins.
Along the Sherman Way corridor and the apartment-heavy stretches of Vanowen Street and Roscoe Boulevard, the older multifamily buildings often have security screen doors and shared-entry hardware. A unit rekey there is usually about the individual apartment lock, while shared entries are a building-management decision. If you are locked out of your unit while sorting this out, see our apartment lockout page.
Near Westfield Topanga and the Downtown Canoga Park business district, the work shifts toward shops: retail master-key and rekey jobs for storefronts that change tenants or staff. Newer townhomes and mixed-use buildings near Westfield Topanga tend to have more modern hardware, which we identify before promising a rekey. We are about 21 miles from our Westwood storefront, and our mobile vans cover Canoga Park routinely.

Call (213) 577-1366Commercial and business lock rekey
A commercial rekey follows the same principle as a house rekey, but the stakes and the logistics are different. A shop in Downtown Canoga Park, a retailer near Westfield Topanga, or a warehouse along the De Soto Avenue industrial corridor may have a dozen employees who have held keys over the years. When someone leaves, or when a new tenant takes over a space, rekeying shuts out every old key at once without replacing every door's hardware.
For businesses with several doors, we often recommend planning the keying instead of just changing pins. A master key system lets one key open everything while individual staff keys open only what they need, and it makes later changes far easier because you rekey a single cylinder rather than reissuing every key. For the broader picture of business door security, see our commercial locksmith page.
If you are not sure whether your commercial locks can be rekeyed, tell us the brand and what the doors are. Storefront hardware, rear doors, panic exits and warehouse doors can all be different, and we confirm in person what is workable before any work begins.
Landlords, property managers and tenant turnover
If you manage rentals in Canoga Park, rekeying between tenants is routine maintenance, not an overreaction. The previous tenant's key should not open the next tenant's door, and in most cases rekeying achieves that without the cost of new locks on every unit. Keeping the same hardware also keeps your unit locks consistent from one door to the next.
We can rekey a set of units on a schedule that fits your turnover, and key them so that your own access remains organized. Our locksmith for landlords page covers how we work with owners and managers, including multiple-unit jobs. If you need spare keys cut once the rekey is done, key duplication is the way to do it, and we copy them from the new key so everything matches.
Why 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. It is also easy to do badly: a rushed rekey can leave a pin out of place or a key that works intermittently. We would rather take a few extra minutes at each lock and test it properly.
A few things that are simply true about how we operate:
- One company from the first phone call to the finished lock. There is no dispatch middleman handing your job to whoever is available.
- A storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, so you can come to us or have us come to you.
- Phone answered 24 hours a day, 7 days a week, year-round, at (213) 577-1366.
- David, the owner and lead technician, oversees the work and the standards behind it.
- We serve 140 cities across Los Angeles and Ventura counties, so Canoga Park is part of a route we run regularly, not a stretch.

Call (213) 577-1366What to know before you hire any locksmith
California requires locksmith companies to hold a BSIS LCO license, issued through the Bureau of Security and Investigative Services. Ask any locksmith you consider for that license information before they start work, and be wary of anyone who dodges the question.
Other sensible things to ask: whether the person at your door works for the company you called, what the quote includes before work begins, and whether they can explain what they are doing to your lock. A good rekey is easy to explain. If the answer to a simple question is vague, trust that instinct.
If you are unsure whether you need a rekey, a replacement or something else, call (213) 577-1366 or use our contact page. We will tell you plainly which fits, even if the answer is a simpler job than you expected.
Frequently asked questions
Can you rekey all house locks to one key?
Yes, in most cases. If your locks are compatible brands and keyways, we can rekey the front door, back door, side door and other deadbolts so a single key opens all of them. We check each lock on site, and if one cannot be matched, we tell you and give you options.
Do I need to rekey locks after buying a house in Canoga Park?
It is strongly worth doing. You cannot know how many copies of the old keys exist, who the previous owners gave them to, or which contractors had access. Rekeying gives you a clean slate with the locks already on the doors, and it is usually the more economical route compared with replacing everything.
How is rekeying different from changing locks?
Rekeying keeps your existing lock hardware and changes only the internal pins and the key. Changing locks means removing the hardware and installing new locks. If your locks are in good shape, rekeying is usually enough. If they are worn, damaged or you want better security, new hardware may be the better call.
Will the old key still work after a rekey?
No. Once the cylinder is rekeyed, the old key will slide in but will not turn. We test this with you before leaving so you can see it for yourself. The new key is the only one that operates the lock.
Can any lock be rekeyed?
Most standard pin-tumbler residential locks can be. Some very worn locks, discontinued keyways, certain specialty cylinders and electronic locks that rely on codes rather than a key may not be good candidates. We look at your hardware first and tell you honestly whether rekeying makes sense.
Do you rekey apartment locks and handle tenant turnover?
Yes. Apartment lock rekey and tenant turnover rekey are common work for us. We can handle a single unit or several, and landlords and property managers can arrange it to fit their move-out schedule. Shared entries or building hardware usually need the owner or manager's approval.
Can you do a commercial rekey for my shop or warehouse?
Yes. We rekey business locks for storefronts, offices and warehouses, including after staff changes or a new tenant takes the space. For businesses with many doors, we may suggest a master key system so that future changes are simpler. We confirm hardware types in person.
Do you come to me, or do I bring the locks in?
Either works. Our mobile vans come to your home or business in Canoga Park, which is the easier option for locks that are still installed on doors. You can also bring cylinders to our storefront at 10740 Wilshire Blvd in Westwood. If you want a mobile visit, our mobile locksmith page explains how that works.
What if my key sticks after the rekey?
A properly rekeyed lock should turn smoothly. If it does not, the cause is often the door, not the cylinder. In older Canoga Park homes, summer heat can swell wood doors and push the deadbolt out of line with the strike. We check alignment and adjust or repair it as needed.
