Change Locks in Downey, CA: Rekey or Replace, Explained Plainly

Should you rekey or replace when you change locks?

Changing your locks means making sure the keys that used to work no longer do. There are two ways to get there, and the right one depends on what is on your doors today. Rekeying keeps your existing hardware and swaps the internal pins and the key, so old keys stop working and you get new ones. Replacing takes the lock off the door and puts a different lock on.

Rekeying is usually the more economical route when the hardware is sound. If your deadbolt turns smoothly, the finish is intact, and you like how it looks, there is rarely a reason to throw it away. Replacement makes sense when a lock is worn, damaged, mismatched, or simply not strong enough for the door it protects. We look at each lock in person and tell you which group it falls into, even when the honest answer is the smaller job.

If you want the full detail on either path, we have separate pages on lock rekeying and lock replacement. This page is about the decision itself and about changing the locks on a whole home so the keys in your pocket are the only keys that work.

Why change your locks after buying a house or moving in?

When you take over a home, you have no way of knowing how many copies of the old keys are out there. Previous owners hand keys to relatives, neighbors, cleaners, contractors, house sitters, and agents, and almost nobody keeps a list. A lockbox on the door during the sale is one more place a key lived. Changing the locks is the only way to reset that count to the keys you are holding.

People call us as a locksmith for a new house, or as a locksmith after moving, for several reasons:

• You bought a home and received an unknown number of keys, or only some of them.
• You moved into a rental and want to know who else can walk in.
• A roommate, partner, or ex still has a working key.
• Keys were lost or stolen, or a wallet or bag went missing with an address inside.
• A remodel or construction project is finished and crews had access.
• A lock was damaged in an attempted break-in and no longer feels trustworthy.

How does a lock change work, from the first call to the last key?

Here is the sequence on a typical whole-house lock change. The details shift with the home, but the order stays the same.

1. You call (213) 577-1366, at any hour. Tell us how many exterior doors you have, what kind of locks they are, and whether you already know if you want to rekey, replace, or just hear our advice.
2. A technician comes to the address in one of our mobile vans. You are dealing with our company from the first call through the finished job, with no handoff to a third-party dispatcher.
3. We walk the property and inspect every exterior lock: front door, back door, side doors, any garage entry, and any secondary deadbolts. We note which are in good shape and which are worn, loose, or damaged.
4. Before any work starts, we explain your options door by door and what is driving the cost of each, so you decide with full information.
5. We rekey the cylinders that can be rekeyed and install new hardware where replacement is the better call.
6. If you want one key for every door, we key the locks alike. If you prefer separate keys for separate doors, we can do that instead.
7. We test every lock with the door open and closed, and we check that the bolt lines up cleanly with the strike plate. A lock that turns on the bench but drags in the door is not finished.
8. You get your new keys and our advice on spares. If you want extra copies cut, we can do that on the spot; see our key duplication page for more.

What affects the cost of changing locks in Downey?

We don't quote numbers on a web page, because the honest price depends on your actual doors. Here is what moves it up or down, so nothing about a quote surprises you.

The biggest factor is rekey versus replace. Rekeying existing hardware generally costs less than buying and installing new locks, but only when the existing locks are in good enough shape to be worth keeping.

• Number of locks: a front door deadbolt is a small job; every exterior door in a house is a larger one.
• Condition of the hardware: worn or damaged locks can't always be rekeyed cleanly.
• Grade and brand of any new lock: basic builder-grade hardware and high-security cylinders sit in very different ranges.
• Finish and style: if you want every door to match, the hardware list can change.
• Extras: adding a deadbolt where there is only a knob, or a keypad or smart lock, adds parts and labor.
• Door and frame condition: a door that has swelled, shifted, or been damaged may need adjustment so the new lock works properly.
• Time of the call: after-hours and holiday service can be priced differently from a scheduled daytime visit.
• Keying choices: keyed-alike sets and restricted keyways are priced differently from standard keying.

When is replacing the better call?

We'd rather be straight about this than sell you hardware you don't need. Rekeying is not always the right move. These are the situations where we usually recommend replacing instead:

• The lock is visibly worn, loose in the door, sticks, or needs jiggling to turn.
• The lock has been forced, drilled, or otherwise damaged.
• A door has only a knob lock and no deadbolt. Adding one is an upgrade, not a rekey. See our deadbolt installation page.
• The locks on different doors are different brands and cannot be keyed alike without swapping some of them.
• You want keypad or app-based entry, which means new hardware by definition. Our smart lock installation page covers that path.
• You want a stronger lock than what the builder installed.

Changing locks in Downey neighborhoods: what we see around town

Downey is mostly single-family homes, and the housing ranges from 1940s bungalows to 1960s ranch tracts, so there are plenty of doors that have been through several owners. In older parts of the city, the original hardware may have been swapped out over the years, which means a single house can have three or four different lock brands on its exterior doors. That is a common reason a whole-house change turns into a mix of rekeying and replacing.

Northeast Downey is known for larger custom homes and ongoing teardown-and-rebuild activity. A home like that may have had a crew of builders, subcontractors, and designers with access during construction. When a build or remodel wraps up, changing the locks closes that chapter. Many remodeled Northeast Downey homes also get keypad or smart-lock hardware at the same visit, which is a natural time to decide which doors get new hardware and which are simply rekeyed.

Orange Estates keeps older estate-style homes on generous lots. Bigger properties often mean more exterior doors to account for, and older hardware on those doors. Whole-house rekeys for buyers in Northeast Downey and Orange Estates are some of the most common lock-change calls in the city. If you bought in 90240, 90241, or 90242, the process is the same: check every exterior door, decide rekey or replace, and key it all so you carry as few keys as you want.

Other parts of town, including Downtown Downey, Southeast Downey, Southwest Downey, and the areas around Furman Park and Rio San Gabriel Park, are a mix of the same bungalows and ranch-style tracts. One note from the climate here: Downey sits on the inland coastal plain, so salt-air corrosion is not a practical concern for your locks. Summer heat is another matter. It can swell wood doors slightly, especially older entry doors facing south with no shade. A swollen door can make a deadbolt bind. We check how the door fits before and after the change, so a new lock isn't blamed for a door problem, and we tell you if the door itself needs attention.

Downey is about 21 miles from our Westwood storefront at 10740 Wilshire Blvd. Our mobile vans cover the city, and we serve 140 cities across Los Angeles and Ventura counties.

Changing locks in an apartment or rental

Apartment corridors run along Paramount Boulevard and other major streets in Downey, and renters change locks for the same reasons owners do: a former roommate, a lost key, or just not knowing who held keys before. If you rent, read your lease and talk to your landlord or property manager first. In many buildings the landlord controls the locks, and a technician will reasonably want confirmation that you have the right to change them.

If you are locked out rather than changing locks, that's a different job, and our apartment lockout page covers it. If you own rental property and want to rekey between tenants, see our page for landlords, which handles turnover rekeys and multi-unit key control.

Why call Wilshire Lock & Key for a lock change?

We have been in business since 1987, and lock changes are among the oldest and most routine jobs a locksmith does. A few things are worth knowing before you choose who comes to your door:

• One company, start to finish. We have a storefront in Westwood and our own mobile vans, so you are not routed through a call center that sells your job to whoever picks it up.
• David, the owner and lead technician, oversees the work. You are not dealing with an anonymous operation.
• We answer the phone 24 hours a day, 7 days a week, year-round, at (213) 577-1366. A lock change after a break-in or a lost wallet does not wait for business hours.
• We explain the rekey-or-replace decision before we start, door by door, rather than defaulting to the bigger job.
• If it's urgent, for example you can't secure the home tonight, our emergency locksmith service page explains how we handle those calls.

What should you do before the technician arrives?

A little preparation makes the visit faster and the quote clearer. Locksmith companies in California are required to hold a BSIS locksmith company (LCO) license, and you should ask any locksmith you call for that license number. It is a fair question. A reputable company will not mind it.

• Count your exterior doors, including side doors, back doors, and any door from the garage into the house.
• Gather every key you have, including spares, garage keys, and any gate or mailbox keys that share a keyway.
• Decide whether you want one key for all doors or separate keys.
• Be ready to show that you live at the address or have the right to change the locks.
• Note anything that sticks, drags, or feels loose, and mention it on the phone.
• If you're considering a smart lock or keypad, tell us which doors, so we bring the right hardware.
