What does it mean to rekey locks?
Rekeying is the quiet fix most people don't know exists. Inside a standard pin-tumbler lock, a row of small spring-loaded pins sits at set heights, and your key lifts each pin to exactly the right level so the cylinder can turn. To rekey a lock, a technician removes the inner plug, swaps in a different set of pins sized for a new key, and puts everything back together. The handle, the deadbolt body, and the strike plate stay on your door. Only the key pattern changes.
The result is that every key that used to work becomes a useless piece of brass, and the new key works. Nobody who held a copy of the old key can open the door anymore, whether that's a previous owner, a former tenant, a contractor, or a friend who once watered your plants. That is the whole point, and it is why rekeying is usually the first thing we suggest when your real worry is who else has a key, not whether the hardware is broken.
It also means a rekey is a different job from a repair. If a lock is worn, damaged, or sticking, rekeying won't cure that. We'll tell you plainly which situation you're in before we touch anything.
When should you rekey your locks?
In Rowland Heights we hear the same handful of reasons again and again. Any of these is a good moment to change who holds the keys:
- You just moved in. You have no way of knowing how many copies of the old keys exist. If you want to rekey locks after moving, the best time is before the first night, so the only working keys are the ones in your hand.
- You are rekeying locks after buying a house. Sellers, agents, previous owners, and past repair people may all have kept a key. Closing on the sale does not take those back.
- A tenant moved out. A tenant turnover rekey is standard practice for landlords, because a returned key does not prove no copy was made.
- You lost your keys. If a key ring disappeared along with anything that points to your address, rekey locks after losing keys rather than hoping nobody finds them.
- A household or roommate situation changed. Someone who no longer lives there may still have a key in a pocket or a drawer.
- You want one key for everything. We can rekey all house locks so the front door, back door, garage-entry door, and side gate all open with the same key.
- If you're standing outside with your keys locked inside, that is a lockout rather than a rekey. We handle those too, but it's a separate job with its own approach.
Locked out or need a locksmith now?
We answer around the clock, every day of the year.
Call (213) 577-1366How does a rekey visit work, step by step?
Whether you bring a cylinder to our Westwood storefront or have a mobile van come to you, the process is the same.
- You call (213) 577-1366. A person answers at any hour, and we ask what's going on: how many locks, what kind (deadbolt, knob, lever, gate lock), and whether anyone is locked out.
- We sort out what's realistic before we head over. If something you describe sounds like it can't be rekeyed, such as a damaged cylinder or an unusual keyway, we say so up front so there are no surprises on your porch.
- On site, we check each lock before opening it. We confirm it turns smoothly, that the bolt throws fully into the strike, and that the door itself lines up. A lock that fights the door is a different problem from a lock with the wrong keys.
- We remove the cylinder, pull the plug, and replace the pins for the new key pattern. New keys are cut to match, and we test each one.
- We reassemble and reinstall the cylinder, then test every lock with the new key from both sides of the door. We also confirm the old key no longer turns.
- You get the new keys. We talk through how many you need and whether one key for all doors makes sense. Extra copies later are a simple key duplication job.
How much does lock rekeying cost in Rowland Heights?
We don't print numbers on a web page because the honest answer depends on the doors in front of us. What we can do is tell you exactly what moves the price:
Rekeying is usually the more economical route compared with replacing every lock, because you're paying for a technician's time and a few small parts rather than new hardware. The exception is a lock that's worn out. Rekeying something that will fail next month wastes your money, so if the hardware is past its useful life, we'll say so. Ask for the full price when you call and before any work begins; we're glad to walk through how it's built.
- How many cylinders you have. A single front door is a smaller job than every exterior door, a garage-entry door, and a side gate.
- The type and brand of lock. Standard residential cylinders are straightforward. Restricted or high-security keyways take more care and sometimes different parts.
- Whether you want all locks keyed alike, so one key opens everything.
- How many new keys you want cut.
- The hour you call. After-hours and weekend calls are different from a scheduled weekday appointment, even though we answer 24/7.
- Distance. Rowland Heights is about 34 miles from our Westwood storefront, and travel is part of a mobile call.
- The condition of the locks. Any repairs a lock needs before it can be rekeyed are separate from the rekey itself.

Call (213) 577-1366Should you rekey, change the locks, or replace them?
Three different jobs often get mixed together, and choosing the right one saves you money and frustration. A rekey keeps the same hardware and gives you a new key. Changing the locks usually means swapping in different hardware, often for a new look or a higher security grade. Lock replacement is for when a lock is worn, broken, or damaged, for example after a forced-entry attempt.
Rekey when the hardware is in good shape and your concern is key control. That covers most move-ins, most tenant turnovers, and most lost-key situations. Move to new hardware when the lock sticks or feels loose, when the door was forced, or when the existing locks are a basic grade and you want something sturdier.
Smart locks add a twist. If you want keypad or app entry, that's a different job from rekeying, and you can read about it under smart lock installation. Many smart locks still have a mechanical key cylinder as a backup, and that cylinder can be rekeyed like any other, but codes and app access are managed separately from the physical key.
Where in Rowland Heights do we rekey locks?
Rowland Heights covers ZIP code 91748, and its housing stock shapes what a rekey looks like here. Many of the tract homes date from the 1960s through the 1980s, which means a lot of original or long-ago-replaced locks that have had many keys cut over the decades. If those locks still work smoothly, a rekey is a sensible way to cancel every key that has ever floated around, without the cost of all-new hardware.
Townhome and condo complexes concentrate along Colima Road and Fullerton Road, and condo and townhome rekeys in those complexes are a regular call. Buyers want the locks changed before they move in, and owners renting a unit out want a clean slate between tenants. Entry doors and deadbolts are the usual targets. Rules about exterior door hardware vary from complex to complex, so check yours if you plan to do more than change the key.
The hillside neighborhoods south of Pathfinder Road are a different picture. View-lot homes there often use side gates and garage-entry doors as primary access points, so a proper rekey includes those doors, not just the front entrance. If you want every access point on one key, tell us up front. The Puente Hills lots are breezy and sun-exposed, and south-facing doors and gate hardware weather faster in the warm, dry summers. Before we rekey a sun-baked cylinder, we check that it still turns cleanly. If it's worn, we'll tell you, and a worn gate lock may be a better fit for gate lock repair than a rekey.
Whether you're near the Nogales Street corridor, the Pathfinder Park area, or the neighborhoods around the Rowland Heights Community Center, the job is the same: we come to you with a mobile van, and you walk away with new keys and locks that match.

Call (213) 577-1366Do you rekey businesses in Rowland Heights?
Yes. A business lock rekey follows the same principle as a home job but with more doors and more people involved. The Colima Road and Fullerton Road shopping plazas are full of restaurants and storefronts, where staff turnover is a fact of life. When an employee who had a key leaves, or a key goes missing from the ring, a commercial rekey cuts off that key without replacing the whole door setup.
Commercial work can involve front doors, back doors, storerooms, and offices, each with different cylinders. We can rekey them so each door has its own key, or key several doors alike so a manager carries one key instead of a ring. If your business needs layered access, with staff keys that open some doors and a manager key that opens all of them, that's a master key system conversation. For the broader range of door work a business may need, see our commercial locksmith service.
Tell us on the call what kind of locks you have and how many doors. Commercial hardware varies widely, and the more we know before we show up, the fewer surprises there are.
Why call Wilshire Lock & Key for a rekey?
We've been in business since 1987, and rekeying is among the oldest and most basic things a locksmith does. We run a real storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties, including Rowland Heights.
When you call (213) 577-1366, you reach us, not a national call center that sells your job to the nearest subcontractor. It's one company from the first phone call to the last test of your lock, with no dispatch middlemen adding a layer between you and the person at your door. David, the owner and lead technician, oversees the work.
One more piece of advice that applies to any locksmith you call, including us: California requires locksmith companies to hold a BSIS LCO license. Ask for the number, and be wary of anyone who dodges the question. A rekey puts the keys to your home or business in someone's hands, so it's fair to ask.
Frequently asked questions
What's the difference between rekeying and changing locks?
Rekeying keeps your existing lock hardware and changes the internal pins so a new key works and the old keys don't. Changing locks means installing different hardware. If your locks work well and you only need new key control, rekeying is usually the more economical route.
Should I rekey the locks after buying a house in Rowland Heights?
Yes, it's one of the most common reasons we rekey. You can't know how many copies of the old keys exist among previous owners, agents, and contractors. Rekeying before you move in means only the keys you hold will open the doors.
Can you rekey all the locks in my house to one key?
Usually, yes. We can rekey the front door, back door, garage-entry door, and side gate so one key opens them all, as long as the locks are in rekeyable condition. Tell us how many locks you have when you call, and we'll confirm what's possible.
Do I need to rekey when a tenant moves out?
It's strongly recommended. A returned key doesn't prove no copy was made. Landlords commonly rekey between tenants so each occupant is the only one with working keys. If you manage rentals, our locksmith for landlords page covers more of how we handle turnover.
Can a lock be rekeyed if I lost all of my keys?
Often yes. We can typically work from the lock itself rather than an existing key, though the approach depends on the lock type and condition. Rekeying after losing keys is also the right move for security, since it cancels the lost key entirely.
Can you rekey a condo or townhome lock on Colima Road or Fullerton Road?
We rekey entry doors and deadbolts in condos and townhomes regularly. Rules about exterior hardware differ between complexes, so if you want anything beyond a key change, check with your association first. A straightforward rekey of your unit's own lock is a routine job.
Is there a lock that can't be rekeyed?
Yes. A badly worn or damaged cylinder, some very basic locks, and certain specialty or high-security systems may not be rekeyable, or may need specific parts. We check the lock before starting, and if rekeying isn't sensible, we explain the alternatives.
Do you rekey businesses and restaurants at night or on weekends?
We answer the phone 24 hours a day, 7 days a week, year-round, at (213) 577-1366. Call, tell us how many doors and what hardware you have, and we'll talk through how to handle it. After-hours timing can affect the price, which we'll explain on the call.
