Why change your locks after buying a house or moving in?
When you get the keys to a new place, you get the keys you were handed. You don't get the keys nobody told you about. The previous owner may have kept a copy. So might a former tenant, a relative, a contractor, a real estate agent, a cleaning service, or a neighbor who once watered the plants. Nobody in that chain is necessarily a bad actor, but you have no way to count the copies, and that's the whole point of changing the locks.
The same logic applies when you move into a rental, end a roommate arrangement, finish a divorce, lose a set of keys, or take over a home from a family member. In every case the question is the same: who can still open this door? A lock change is how you reset that answer to 'only the people I choose.'
People searching for a locksmith for a new house or a locksmith after moving are usually juggling a lot at once: boxes, utilities, closing paperwork. Locks tend to land at the bottom of the list. We'd put them near the top, and the job itself is usually one of the more manageable items on the list.
Rekey or replace locks: which one do you need?
'Change locks' is the phrase most people use, but it covers two different jobs. Sorting out which one fits your door is the first thing we do, and it's the part most customers don't know to ask about.
Rekeying keeps the lock hardware on your door and changes what's inside it, so the old keys stop working and a new key takes over. Replacing means taking the lock off and installing a different one. Both end with a door that the old keys can't open. They differ in cost, in what you end up with, and in whether your current hardware is worth keeping.
- Rekey when the lock is in decent mechanical shape, you like how it looks and feels, and your main goal is cutting off old keys. It's usually the more economical route, and all your locks can be set to one key. Our lock rekey service page explains the process in detail.
- Replace when the hardware is worn, loose, corroded, damaged, or just doesn't suit you anymore, or when you want a different grade of security, a different finish, or a different type of lock. See our lock replacement page for how that goes.
- Replace when there's no deadbolt, or the existing deadbolt is weak or poorly fitted. Adding or upgrading one is covered under deadbolt installation.
- Rekey when you have several matching locks and want one key for the front door, back door, and side entries.
- Replace when a lock is a mismatched collection from years of piecemeal repairs and nobody can say what's what.

Call (213) 577-1366How does a lock change work, step by step?
Here's how a typical visit runs. We adjust it to your doors, but the order stays largely the same.
- You call (213) 577-1366. Tell us what you're dealing with: new house, lost keys, a tenant moving out, or just 'I'm not sure.' Mention how many exterior doors, gates, and garage-entry doors you have.
- We send a mobile van from our Westwood base, with the tools and a range of hardware on board for a typical visit.
- On arrival, we look at every lock you want changed: brand, condition, fit, and whether the door and strike plate are in good shape. A lock is only as solid as the door it's mounted in.
- We lay out the options plainly: rekey, replace, or a mix by door. We explain what each means for cost and for your day-to-day, then you decide.
- We do the work. Rekeyed locks get new pins matched to a new key. Replaced locks come off, new hardware goes on, and we check alignment so the bolt throws smoothly into the frame.
- We test every lock and every key, from both sides of the door, more than once. A lock that works on the first try and sticks on the fifth isn't done.
- We hand over the new keys, show you anything worth knowing about the hardware, and tell you what to do about extra copies. If you want more keys cut, key duplication is available, though we'd suggest waiting until you know who actually needs one.
What affects the cost of changing locks?
We don't quote prices on a web page, because the honest answer depends on your doors. Anyone who gives you a flat number without knowing what's on them is guessing or planning to adjust it later. Here's what actually moves the cost up or down, so you can judge any quote you receive, ours included.
- Rekey versus replace. Rekeying existing locks is generally the lighter-cost option. Replacement adds the cost of the new hardware itself.
- Number of locks. More doors means more work, though doing several at once is usually more efficient than coming back for each one.
- Grade of hardware. Basic builder-grade locks, mid-range residential locks, and high-security cylinders sit in quite different places. If you're curious about the top end, read about high-security locks.
- Condition of existing locks. Some old locks rekey cleanly. Others are worn enough that rekeying isn't worth it, and we'll say so.
- Door and frame condition. A loose strike plate or a bored hole that doesn't line up can add work.
- Special hardware. Gate locks, multipoint systems, and electronic locks all involve more than a standard knob or deadbolt.
- Timing and location. After-hours calls and distance from our base can factor in. We explain this on the phone before we dispatch, not after we arrive.

Call (213) 577-1366Should you stick with keys, or use this chance to upgrade?
A lock change is a natural moment to ask whether you want to keep carrying keys at all. For some households, the answer is yes: a good mechanical deadbolt is simple, has no batteries, and is easy to hand to a house sitter. For others, a keypad or smart lock makes more sense, particularly if you regularly need to let people in without handing over a physical key.
If you're curious, our smart lock installation page covers what's involved. We'll be straightforward about the trade-offs: electronic locks add convenience, but they also add batteries, firmware, and more parts that can fail. Whether that's worth it depends on how you live. We're not going to push one.
Whatever you pick, make sure the door itself is up to the job. A strong lock in a weak frame is a false comfort, and checking that is part of what we do when we change locks.
Changing locks in Rowland Heights: what we see locally
Rowland Heights, ZIP code 91748 in unincorporated Los Angeles County, has a mix of housing that shapes how lock changes tend to go. Much of the area is tract homes from the 1960s through the 1980s. Homes that age have often had hardware swapped, patched, or half-upgraded over the decades, so we look at what's actually on each door rather than assuming. If you've just bought one of these homes, expect us to ask whether the front, back, and garage-entry locks all match and whether any were replaced at different times.
Condos and townhomes cluster along the Colima Road and Fullerton Road corridors. A condo or townhome rekey is one of the more common reasons people in that part of Rowland Heights call us. A single owner wants new keys, often for more than one door, and the existing hardware is perfectly fine. That's a classic rekey job. If you live in a complex, check what your community permits for exterior hardware before you swap anything out.
The hillside neighborhoods south of Pathfinder Road, along with the Pathfinder Park area, include newer subdivisions and some gated communities. On view-lot hillside homes, side gates and garage-entry doors often act as the primary access points, which means a lock change there should include those, not just the front door. Many people forget the side gate until it's pointed out. If a gate latch or lock is part of your property, our gate lock repair page covers that work.
Climate matters too. Summers in the eastern San Gabriel Valley run warm to hot and dry, and hillside lots in the Puente Hills are breezy and sun-exposed. Weathering of south-facing doors and gate hardware is the main concern. When we change locks on a south-facing door, we pay attention to finish and condition, because sun-baked hardware can wear faster. Sometimes that's a reason to replace a lock we might otherwise have rekeyed.
Along the Nogales Street corridor, too, we work on a mix of homes, and the same rule holds: we decide rekey or replace door by door, not as a blanket policy.
We're based at 10740 Wilshire Blvd in Westwood, about 34 miles from Rowland Heights, and we serve the area by mobile van. If you're locked out and need to get in before you change anything, see our house lockout page.

Call (213) 577-1366Other times to change locks besides a move
New homeowners are a big share of lock-change calls, but not the only ones. Here are other situations where a change is the sensible move:
- You lost a set of keys, or a wallet or bag containing them was taken. Even if you think they'll turn up, a lost key with your address attached is a risk.
- A roommate, partner, or family member moved out and you aren't certain every key came back.
- A tenant moved out of a rental you own. If that's your situation, see our locksmith for landlords page for turnover-focused service.
- A contractor, house cleaner, or caretaker had keys for a project that's now finished.
- You've had a break-in or attempted break-in, and want the entry points secured promptly.
- Your existing keys have been copied so many times that you've lost track of who has one.
Why call Wilshire Lock & Key for a lock change?
We've been in business since 1987, and a lot of the job is just knowing what's likely behind a door before we open the box. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so the people answering the phone are part of the same operation as the people at your door. There's no dispatch middleman reselling the job to whoever's closest.
David, our owner and lead technician, oversees the work. That matters because a lock change involves judgment calls: rekey or replace, keep this deadbolt or swap it, whether a door needs attention first. Those calls shouldn't depend on which tech got the ticket. We'd rather tell you a lock is fine to keep than sell you something you don't need.
Our phone, (213) 577-1366, is answered 24 hours a day, 7 days a week, all year. We serve 140 cities across Los Angeles and Ventura counties, so Rowland Heights is one stop among many places we work regularly. If you'd like to talk before booking, you can also reach us on our mobile locksmith page or call directly.
How to check any locksmith before you let them change your locks
Changing your locks means handing someone access to your security, so it's reasonable to be picky. California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith, including us, for that license number before work begins, and check it with the state if you want to be sure.
A few other signs of a trustworthy visit: the company gives you its name when it answers the phone, explains the cost factors before sending anyone, tells you whether it's recommending rekey or replace and why, and doesn't pressure you into replacing hardware that works. If something feels rushed or vague, it's fine to stop and call someone else.
Frequently asked questions
Do I need to change locks after buying a house in Rowland Heights?
We recommend it. You can't know how many copies of the old keys exist or who holds them. Changing or rekeying the locks resets that, and it's one of the simpler ways to start fresh in a new home. It matters on the front door, but also on the back door, garage-entry door, and any side gates.
What's the difference between changing locks and rekeying them?
'Changing locks' is the general phrase. Rekeying changes the inside of your existing lock so old keys stop working and a new key fits. Replacing swaps the hardware. Both leave you with a door the old keys can't open. We help you pick between them based on the condition of your current locks and what you want from them.
Is it cheaper to rekey or replace?
Rekeying is usually the more economical route because you keep your existing hardware. Replacement adds the cost of new locks, which varies widely by grade and finish. If your current locks are worn or damaged, rekeying them may not make sense, and we'll tell you honestly when that's the case.
Can you change all my locks to use the same key?
Often yes. Rekeying lets multiple locks share a single key, which is convenient for front, back, and garage-entry doors. Compatibility depends on the brand and type of each lock, so we check them on site. Some may need replacing if they can't be rekeyed to match.
How do I get a lock change in Rowland Heights outside business hours?
Call (213) 577-1366. The line is answered 24 hours a day, 7 days a week, all year. After-hours work can affect cost, and we explain that on the phone before dispatching a van, so there are no surprises when we arrive.
Do I need to be home while you change the locks?
Someone authorized should be there, at least at the start and end. We need access to every door being worked on, and you'll want to test the new keys with us before we leave. If you're buying or moving and can't be present, call and we'll talk through what's workable.
Can I change the locks in my condo or townhome?
Often you can rekey or replace the locks on your own unit's entry door, but communities sometimes have rules about exterior hardware, finish, or who may do the work. Check your association's guidelines first. If you're along Colima Road or Fullerton Road, we can work with whatever your complex allows.
Does a lock change cover my side gate and garage door too?
Only if you ask us to include them. On many hillside homes, side gates and garage-entry doors are primary access points, so we suggest listing every entry when you call. Gate locks can need different hardware than a standard door, so mention them up front.
