Change Locks in La Mirada, CA: Rekey or Replace, Done Right

Rekey or replace: which one do you actually need?

When people ask us to change locks, they usually mean one of two jobs. Rekeying keeps the lock hardware on your door and changes the inside of the cylinder, so the old keys stop working and a new key takes over. Replacing means taking the hardware off and installing a different lock. Either way, the result you care about is the same: the keys that used to open your door no longer do.

The difference is what you are left with. A rekey is usually the more economical route when the lock itself is in good shape. A replacement makes sense when the hardware is worn, damaged, mismatched, or when you want something stronger or more convenient than what is on the door now. We would rather ask you a few questions than assume, so we start by looking at what is actually installed. If you already know you want one path, you can read more about lock rekeying or lock replacement on their own pages. If you are not sure, that is exactly what this page, and a phone call to David's team, is for.

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

Closing day hands you a set of keys. It does not tell you how many other sets exist. Over the years a house collects copies: previous owners, real estate agents, contractors, relatives, a neighbor who watered the plants. You cannot know who still holds one, and you cannot get them back. Changing the locks is the only way to start from a known number of keys, and it is one of the quicker security steps a new homeowner can take.

The same logic applies to anyone settling into a new place, not just buyers. A locksmith for a new house and a locksmith after moving are often the same call, made in the first week.

• You bought a house and want every old key made useless.
• You moved into a rental and the previous tenant's key situation is unclear. Check your lease and talk with your landlord first, since the door may not be yours to alter.
• A roommate or partner moved out and still has a key.
• A key was lost or stolen, or a break-in left you uneasy about the door.
• You are a property owner turning over a unit between tenants. Our locksmith for landlords page covers that side of the work.

How does a lock change work, step by step?

Here is how a typical visit goes. The details shift with your doors, but the order stays much the same.

1. You call (213) 577-1366 and tell us what doors you have, what is on them, and why you are changing the locks. The line is answered 24 hours a day, every day of the year.
2. We come to you in a mobile van. If you are locked out of a house you just bought, tell us on the call, because that changes how we begin.
3. We look at each lock: brand, age, condition, how the door closes, and whether the strike plate and frame are sound.
4. We tell you what we recommend for each door, rekey or replace, and explain why in plain terms. You decide.
5. We do the work. For a rekey, we take the cylinder apart and reset it to a new key pattern. For a replacement, we fit the new hardware to the existing door preparation where we can.
6. We test every lock with the new keys, with the door open and closed, and we confirm the old key no longer turns.
7. We hand over the keys and talk through anything worth knowing, such as extra copies or a weak spot in the door or frame.

How do we decide between rekeying and replacing?

There is no rule that fits every door, so we judge each one. These are the things that tip the decision.

• Condition of the hardware. A sound lock that turns smoothly is a good rekey candidate. A lock that sticks, wobbles, or has a worn latch is usually worth replacing.
• Matching keys. If you want one key to open the front door, back door, and side gate, we can often pin the locks to match, depending on the brands in place.
• Security level. Some builder-grade hardware can be rekeyed but is not what we would choose to protect a front door. If that is the case, we say so.
• Missing hardware. If the door has no deadbolt at all, that is an installation question. See deadbolt installation for how we handle that.
• Convenience. If you would rather use a code or your phone than carry keys, a replacement with an electronic lock may fit better than a rekey.
• Mixed sets. When every door in a home has a different brand and a different key, consolidating is often easier with replacement on a few doors and rekeying on the rest.

What affects the cost of changing locks in La Mirada?

We do not post prices on this page because the honest answer depends on your doors. What we can do is tell you exactly what moves the cost, so nothing about the quote surprises you.

In general, rekeying existing locks is the lighter-cost option compared with buying and installing new hardware, because you are not paying for new locks. Replacement costs more or less depending on what you choose.

• How many locks are being changed. Front door, back door, side door, garage entry, and patio slider all count.
• Rekey versus replace, and for replacement, the grade and type of hardware you pick.
• Whether locks can be matched to one key or each needs its own.
• The condition of the door and frame. A lock cannot do its job if the strike plate is loose or the wood is split, and fixing that adds work.
• Electronic or smart hardware versus conventional mechanical locks.
• The hour of the call. Late-night and holiday service takes us away from other things, and we will explain that on the phone.
• Distance. Our storefront is in Westwood and La Mirada is about 29 miles away, so we give you a realistic arrival estimate when you call.

Changing locks in La Mirada: tract homes, Biola-area rentals, and HOA townhomes

La Mirada was master-planned and largely built out in the 1950s, and single-story ranch tract homes dominate the city. A common call for us is rekeying a tract home right after a sale, in neighborhoods off Rosecrans Avenue and across ZIP code 90638. A house that old has probably had its hardware swapped, patched, or mixed over the decades, so we look at each door before deciding what to do. Sometimes the front door has been upgraded while the back door still has something tired on it. It is worth checking all of them, not just the one you use most.

Homes toward the Puente Hills on the east side, including the Hillsborough and Knolls at Hillsborough area, tend to be newer and larger than the original tracts. Larger homes often mean more exterior doors to account for, so we walk the whole house rather than assume it is just front and back.

Around Biola University, a lot of the housing is student rentals. Turnover is frequent, and keys get passed around. If you are a tenant, talk to your landlord before changing anything. If you manage the property, a fresh set of keys between occupants is a sensible habit. If you ever get locked out of your own door in the middle of this, we handle that too through our house lockout service.

Condominium and townhome communities, including the La Mirada Landmark adult community, add HOA-managed stock with controlled-access entries. Our work is at your unit's own door, not the community gate, and it is smart to check your HOA rules on exterior hardware first. In the townhome communities near La Mirada Regional Park, owners often ask about going keyless when they change locks. If that appeals to you, smart lock installation is worth a look before you commit to a standard replacement.

Does La Mirada's heat affect lock changes?

It can. La Mirada sits slightly farther inland than neighboring Gateway Cities and runs a few degrees warmer in summer. Seasonal heat can swell wood entry doors in the older tracts, and a swollen door can make a perfectly good lock feel like it is failing: the bolt drags, the key is hard to turn, the latch does not line up. Before we sell you a new lock, we check whether the door is the real problem. Sometimes the fix is adjusting the strike plate, not replacing hardware.

The other side of that is that salt-air exposure here is negligible, so corrosion is rarely what kills a lock. When hardware in La Mirada is worn, it is more often just age and use.

Why call Wilshire Lock & Key for a lock change?

We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties, La Mirada among them. We run a storefront at 10740 Wilshire Blvd in Westwood plus mobile service vans, so the person who comes to your door works for the same company that answers the phone. There is no dispatch middleman passing your job to whoever is free.

David, the owner and lead technician, oversees the work. That matters on a job like this because the right call is often a judgment call, and we would rather tell you a rekey is enough than push hardware you do not need. Our mobile locksmith service means we come to your door, and the phone is answered 24 hours a day at (213) 577-1366.

What should you ask any locksmith before they start?

California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, called a BSIS LCO license. Ask any locksmith for that number before work begins, including us. It is a fair question, and a company that dodges it is telling you something.

Also ask these: Will you tell me what you recommend and why, before you start? Who will be at my door? What drives the cost, and when will I know the total? Are you giving me new keys, and how many? Straight answers to those save a lot of trouble later.
