Change Locks in Whittier, CA: Rekey or Replace, Explained Straight

Should you rekey or replace when you change locks?

When people say they want to change the locks, they could mean two different jobs, and most don't know which one they need until someone explains it. Rekeying keeps your existing lock hardware and changes what is inside the cylinder, so the old keys stop working and a new key takes over. Replacing means taking the hardware off the door and installing different locks. Both end with the result you actually care about: the keys other people hold no longer open your door.

For most Whittier homes with locks in decent shape, rekeying is the lighter-cost option and usually the more economical route. It uses less hardware, it is quicker to do, and every lock on the property can be keyed alike, so you carry one key instead of a ring of four or five. We suggest it when the locks are sturdy, turn smoothly, and all you want is new key control.

We suggest replacing the hardware when the lock itself is the problem. A rekey on a lock that is already failing just gives you a new key for a failing lock, which is money spent in the wrong place. That is why we look at every door before recommending anything, and why we won't push the bigger job when the smaller one will do.

• Rekey when the locks are in good working order, the finish is fine, and you only need new keys.
• Replace when the hardware is worn, loose, damaged, or a very basic builder-grade set you don't trust.
• Replace when you want something different: another finish, a higher security grade, or a keypad.
• Replace when the door has no deadbolt and you want one, or when the existing lock doesn't fit the door properly.
• Either way, you decide. We explain what we see and what each choice means.

Why change locks after buying a house or moving in?

Nobody can tell you how many keys to a house exist. Sellers hand over the keys they remember. They can't hand over copies they never knew were made: the set a previous owner gave a relative, the key a contractor kept, the one a house cleaner or a neighbor held for years, the spare a former tenant never returned. A lock change after buying a house closes all of that at once, and it is the first thing we suggest to anyone calling a locksmith for a new house.

The same logic applies when you move into any new place. If you're an owner, changing locks after moving in is simple and sensible. If you rent, check your lease and talk to your landlord before altering hardware, because the locks may belong to the property and your landlord may want to manage the keys. Many landlords are happy to have a locksmith rekey between tenants, and we work with them on exactly that.

There are other good reasons to change locks that have nothing to do with a move: a lost or stolen key, a breakup or roommate leaving, a key held by someone you no longer work with at home, or a break-in where the lock was damaged. If you're standing outside your door right now with no key, that is a different call. Go to our house lockout service instead, and we can talk about changing the locks once you're inside.

How we change your locks, step by step

There is no mystery to the process, and you should know what is happening on your own door. Here is how a typical lock change goes with us.

1. You call (213) 577-1366 and tell us about the property: how many exterior doors, what kind of locks are on them, and whether you own or rent. Photos of the locks help if you can send them.
2. We confirm that you are the owner or an authorized resident before we change anything on a door. Closing paperwork, a lease, or ID that matches the address all work.
3. We walk every exterior door: front, back, side, garage entry, sliding doors, and any gate or outbuilding lock you want included. We check how each lock turns, how the door sits in the frame, and what condition the hardware is in.
4. We tell you what we recommend for each door, rekey or replace, and why. You hear the reasons plainly, and you choose.
5. We agree on the total before work starts, then do the job at the door: rekeying cylinders, or removing and installing new hardware, and cutting keys that match.
6. We test every lock repeatedly, with the door open and closed, and fix any strike or latch alignment that makes the lock drag.
7. We hand over the new keys, tell you exactly how many were cut, and confirm the old keys no longer operate the locks.

What affects the cost of changing locks in Whittier?

We don't print price figures on a web page because the honest answer depends on your doors, and a made-up number helps no one. What we can do is tell you exactly what moves the total up or down, so nothing surprises you when we give you a quote.

• Number of locks: a single front door is a smaller job than a house with several exterior doors, a garage entry, and a patio slider.
• Rekey versus replace: rekeying generally costs less than new hardware, as long as the existing locks are worth keeping.
• Hardware grade: basic knobs, solid deadbolts, and high-security cylinders sit in very different ranges.
• Specialty hardware: mortise locksets, vintage plates, and unusual keyways take more time and sometimes need special parts.
• Keyed-alike setup: putting every door on one key is a common request, and it affects the work involved.
• Door and frame condition: if a door has swollen, sagged, or moved so the bolt won't line up, that fix is part of the job.
• Extra keys: additional copies add to the total, and we'll ask how many you want.
• Time of day and travel: after-hours calls and distance to your address can factor in. Our storefront is in Westwood and our vans come to you, so we'll explain how that applies to your location.

Changing locks in Whittier's older homes near Uptown and College Hills

Whittier has some of the oldest housing in southeast Los Angeles County. The city dates to its 1887 Quaker founding, and the Victorian-era and Craftsman homes from that period surround Uptown Whittier and Whittier College. Many of them still have original mortise locksets and vintage hardware. If you've bought one of these houses in College Hills or near Uptown, your lock change is a different conversation than it would be in a newer tract home.

A mortise lock sits inside a pocket cut into the edge of the door, and the cylinder is a separate piece from the lock body. That often means we can rekey the original lock instead of tearing it out, which keeps the character of the door and avoids cutting into old wood. It is frequently the better choice on a historic door. Honest caveat: not every vintage lockset can be rekeyed, and some are so worn that they need repair or careful part replacement first. We look at the lock before telling you which it is.

The climate matters here as well. Whittier runs warmer than the coastal plain, and the wet-winter, dry-summer cycle visibly swells and shrinks old wood doors. A deadbolt that binds in winter or rattles loose in a hot, dry September may not be a bad lock at all. It may be a door that has moved. We check the fit before blaming the hardware, because swapping a good lock onto a swollen door just moves the problem to a new lock.

Rekeys for hillside homes, ranch tracts, and apartments

Different parts of Whittier call for different lock changes. East Whittier is dominated by mid-century ranch tracts, where homes tend to share a similar door layout: a front entry, a back door, a garage entry, and often a slider. For these, a full rekey to one key across every door is usually the sensible route. Friendly Hills and Rideout Heights carry larger custom hillside homes, which often have more exterior doors and a mix of hardware from different eras of remodeling. Rekeying a hillside home so every door answers to a single new key is one of the most common change-lock jobs we're asked about, and it saves a lot of key-juggling afterward.

If you're upgrading as part of the change, we can add a deadbolt on a door that only has a knob lock, or talk through a smart lock if you'd rather use a keypad or phone than carry keys. Those are bigger decisions than a basic lock change, and we'll tell you honestly whether they suit your doors.

We take change-lock calls across Whittier, including ZIP codes 90601, 90602, 90603, 90604, 90605, and 90606, and neighborhoods such as Michigan Park, Murphy Ranch, the Palm Park area, Five Points, and the Whittwood area. Apartment buildings near Uptown and along Whittier Boulevard are part of that, too. Whittier is about 24 miles from our Westwood storefront, so our mobile vans do the traveling and the work happens at your door.

Changing locks between tenants and in student rentals

Rentals near Whittier College are a pattern we understand well. Student housing turns over, keys get passed to friends and roommates, and a key that went missing last spring may still be out there. Lockouts at student rentals are a common scenario in the area, and the best way to cut down on them is to start each tenancy with a clean set of keys that the occupants can account for.

If you manage rental property in Whittier, rekeying between tenants is the standard way to keep key control without replacing every lock. It costs far less than new hardware, takes less time, and keeps all your units on a system you can track. Our locksmith for landlords service covers that kind of ongoing work. For tenants, again, check with your landlord first before having any lock changed.

Whichever side you're on, the goal is the same: one clear list of who holds a key, and a lock that proves it.

Why call Wilshire Lock & Key to change your locks

We've been in business since 1987, and we've been changing locks for people who just moved in since long before most online locksmith listings existed. We have a real storefront at 10740 Wilshire Blvd in Los Angeles (Westwood), plus mobile service vans, and we serve 140 cities across Los Angeles and Ventura counties. When you call, you reach us, not a call center that sells your job to whichever subcontractor picks up. One company handles it from the phone call to the finished lock, with no dispatch middlemen in between.

David, the owner and lead technician, oversees the work, which matters for a job like this. Deciding whether to rekey or replace takes judgment, and judgment is what separates a locksmith from someone who sells the same box of hardware to everyone. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, all year, so you can call the night you get your keys, not just on a business day.

One more thing worth knowing: California requires locksmith companies to hold a BSIS LCO license, which is the state's locksmith company license. Ask any locksmith you're considering for their license number before they touch your door. It's a fair question and a good habit, and it protects you from the people who show up with a drill and a sales pitch.

After the locks are changed: a short checklist

A lock change is only as useful as your follow-through. Once the work is done, count the new keys and decide who really needs one. If you want spares for family members or a trusted neighbor, we can handle key duplication with the new key so copies are made from a good original.

Don't forget the other ways into your home. Garage door opener codes, alarm codes, and any keypad or gate codes from the previous owner or tenant should be changed too. A new lock on the front door doesn't help if an old code still opens the garage.

• Keep the extra keys somewhere secure, not under a mat or planter.
• Write down who holds which key.
• Change garage, alarm, and gate codes you inherited.
• If a door starts sticking after a season change, call us before forcing it.
