Should you change, rekey, or replace your locks in Cerritos?
People who search for a lock change service usually mean one of two things. Either they want every key that ever opened the door to stop working, or they want different hardware on the door: a stronger deadbolt, a new finish, a keypad. Those are different jobs, and the right answer depends on what is on your door today. So we don't start with a sales pitch. We start by looking at the locks you have.
Changing locks is the umbrella term, and underneath it sit two real options. Rekeying keeps your existing lock body and changes the internal pins so the old keys stop working and a new key takes over. Replacing removes the hardware and installs new locks. In many Cerritos homes, rekeying is all that is needed, and it is usually the more economical route. In others the hardware is worn, damaged, or simply not what you want, and replacement is the honest call. We'll tell you which one your door needs, even when that means the smaller job.
If you already know you only want the keys changed, our page on lock rekeying in Cerritos goes into that process in detail. If you want new hardware on the door, see lock replacement in Cerritos. If you're not sure, that is exactly what this page, and a phone call, are for.
When is it time to change your door locks?
A lock does not wear out on a schedule, but there are clear moments when changing it makes sense. Most of them come down to one question: do you know who has a working key?
- You just bought a house or condo and cannot know how many copies the previous owner, agents, contractors, or neighbors were given.
- You moved into a place and have no idea who lived there before, or you are a locksmith-for-new-homeowners type of customer who simply wants a clean start.
- A key was lost or stolen, especially if it was ever stored with your address on it.
- A roommate, partner, or former employee moved out and you would rather not rely on getting every key back.
- You have a drawer full of different keys for one house and want a single key that works the front door, back door, and garage entry.
- The lock sticks, grinds, or needs jiggling, which often means worn pins or a loose cylinder.
- There has been a break-in or an attempt, and the door or lock was damaged.

Call (213) 577-1366Rekey or replace locks: how we decide
The decision is practical, not philosophical. We look at the condition of the lock, the quality of the hardware, and what you want out of the door afterward. Here is the way we think about it.
Rekeying makes sense when the lock is in good working order, is a standard brand that can be re-pinned, and your only problem is that other people may hold keys. It also works well when you want several locks on the property to share one key. It leaves your existing hardware and finish in place, which matters if you like how the door looks.
Replacement makes sense when the lock is worn, loose, cracked, or failing, when the finish is badly weathered, when the hardware is a low-grade builder-installed set you would like to upgrade, or when you want a different type of lock altogether. It also makes sense when the door has no real deadbolt, because rekeying does not turn a weak lock into a strong one. It only changes which key opens it.
A few things we check before recommending either route:
- Whether the lock turns smoothly with the current key, or already feels rough.
- Whether the cylinder and latch are firmly mounted and line up with the strike plate.
- Whether the brand and model can be rekeyed, since a few cannot.
- Whether the deadbolt actually throws into the frame, or only partway.
- Whether you want to add a new deadbolt, which is its own install; see our deadbolt installation service.
How does a lock change work, step by step?
A lock change is not complicated, but doing it carefully is the difference between a door that works for years and one that sticks in a month. This is the sequence we follow at a house or condo in Cerritos.
- You call (213) 577-1366 and tell us what is going on: new house, lost key, worn lock, or not sure. A person answers, any hour of the day or night.
- We ask about the doors involved, how many locks there are, and what brand they are if you can see it. That lets us bring the right pins, cylinders, and hardware in the van.
- We come to the property and look at each lock and door before touching anything. This is where we tell you whether rekey or replace is the better fit.
- You get the options and the pricing approach explained before work starts, so nothing about the cost is a surprise at the door.
- We do the work: re-pinning cylinders for a rekey, or removing and installing new hardware for a replacement, and making sure latches and strike plates line up.
- We test every lock with the new key from both sides of the door, more than once, and confirm the old key no longer works.
- We hand over the new keys, show you how to get more copies cut if you need them, and answer any questions before we leave.

Call (213) 577-1366What affects the cost of changing locks?
We don't quote numbers on a web page because a lock change is not one fixed job. What we can do is tell you honestly what moves the cost up or down, so you know what to expect when we give you a quote.
- Rekey versus replace. Rekeying existing locks is usually the lighter-cost option, while new hardware adds the cost of the hardware itself.
- How many locks are involved. A single front door is a different job from every exterior door, a garage entry, and a side gate.
- Hardware grade and brand. Basic hardware and high-security cylinders are priced very differently, and finish choices matter too.
- Smart or keypad features. Electronic locks cost more than mechanical ones and take longer to set up.
- Door condition. If a door is misaligned, the bore is damaged, or the strike plate needs repair, that adds work beyond the lock.
- Time of day. Calls in the middle of the night or on a holiday are handled differently from a planned daytime appointment.
- Travel distance. Cerritos is about 29 miles from our Westwood storefront, and we'll explain how that factors in when you call.
Changing locks after buying a house in Cerritos
Cerritos grew out of the dairy farms of Dairy Valley in the 1960s and 1970s, and most homes here are ranch and two-story stucco tract houses from that era, largely owner-occupied. That shapes what a lock change looks like here. If you've bought in Cerritos Terrace, Concord Place, or one of the older tract streets in the 90703 ZIP, there is a good chance the hardware on the doors has been there a long time, or was swapped piecemeal by past owners. Rekeying those tract homes is one of the most common jobs we do in the city, and it is often the right first step: the existing locks may be fine, you just need the keys to be yours alone.
When we visit a newly purchased home, we look at every exterior door, not only the front. Tract homes often have a front door, a back slider or patio door, and a garage entry, each sometimes keyed differently. We can usually bring them onto one key so you are not carrying three. We also look for deadbolts that are loose, strike plates screwed into thin trim rather than the frame, and old hardware that no longer turns cleanly, since those are the points where replacement is smarter than a rekey.
Cerritos also has townhome and condo developments near the Towne Center and along the major corridors. Condo and townhome doors are often shared-wall or common-entry situations, so before changing anything we'll ask what you're allowed to change, since some associations specify the hardware on exterior doors. Check your association's rules if you're not sure.
Shadow Park is a gated enclave of roughly 394 homes built in the late 1970s, with staffed gate access. If you buy there, the door locks on your own home are still yours to change, and we handle that the same way as anywhere else. What changing your front door locks does not do is change who has access through the community gate. That is managed separately by whoever runs the community, so it's worth asking them about gate credentials when you move in. For gate hardware that needs repair, see our gate lock repair page.
One climate note that is specific to Cerritos: it is inland, with a weaker marine influence than the coastal cities, so summer afternoons run warmer and a sun-exposed door can expand slightly. If a door sticks only in the late afternoon, the problem may be the fit of the door rather than the lock, and we check that before replacing hardware. The upside is that salt corrosion is not a meaningful factor here, so finish choice is more about how you want the door to look than about fighting corrosion.

Call (213) 577-1366Which upgrades are worth adding during a lock change?
Since we're already at the door with the old hardware off or the cylinders out, a lock change is a convenient time to deal with other things. None of these are required, and we'll tell you honestly if we think one is unnecessary for your situation.
Keyed-alike setups let one key open several locks, which is the biggest daily convenience for most households. Adding or upgrading a deadbolt improves the physical security of a door, which a rekey alone does not. If you'd rather not carry a key for some doors, a keypad or smart lock may suit you, and we cover that on our smart lock installation page. Finally, once your new keys are set, key duplication gets spare copies into the hands of family members without having to come back to the original.
We would rather you leave with a plan that matches how you live than with the most expensive hardware on the shelf. If a standard rekey solves your problem, that is what we will recommend.
Why call Wilshire Lock & Key for a lock change?
There are plenty of locksmith listings that route your call through a dispatch center and send whoever is nearby. That is not how we work. Here is what is actually different about us:
- We've been in business since 1987, so the situations you describe are ones we have handled many times.
- We run a real storefront at 10740 Wilshire Blvd in Westwood, plus mobile service vans. The shop is where parts, cylinders, and key machines live, and the vans bring that to you.
- We are one company. There are no dispatch middlemen between your call and the technician who shows up.

- The phone is answered 24 hours a day, 7 days a week, year-round, including 24-hour locksmith service in Cerritos when a lock change cannot wait.
Licensing, and what to ask any locksmith
California requires locksmith companies to hold a license through the Bureau of Security and Investigative Services, known as a BSIS LCO license. Whoever you hire to change the locks on your home, ask for their license number before work begins, and be cautious with anyone who is vague about it or who shows up in an unmarked vehicle under a different company name than the one you called.
Also ask for a clear explanation of why they recommend rekeying or replacing, and what the quote covers before they start. A good locksmith will be comfortable answering both.

Frequently asked questions
What is the difference between changing locks and rekeying?
Rekeying changes the inside of your existing lock so old keys stop working and a new key does. Changing or replacing locks usually means installing new hardware. Both end with locks that only your keys open, and we help you pick based on the condition of what is on the door.
Should I change the locks after buying a house in Cerritos?
Yes, it is a sensible first step. You cannot know how many copies the previous owner, agents, or contractors hold. In many Cerritos tract homes, a rekey is enough, though we'll check each door and recommend replacement where the hardware is worn.
Is it cheaper to rekey or replace locks?
Rekeying is usually the more economical route when your locks are in good condition, since you keep the existing hardware. Replacement costs more because it includes new hardware. Exact cost depends on the number of locks, hardware grade, and the time of the call, and we explain it before we start.
Can you change the locks on a door that is locked right now?
If you are locked out, we first need to get you inside, then we can change the locks in the same visit if you want. See our house lockout service for that part. Tell us on the phone so we bring the right equipment.
Do you change locks at night or on weekends?
Yes. Our phone is answered 24 hours a day, 7 days a week, all year, at (213) 577-1366. If your situation is urgent, such as a lost key or a break-in, say so and we'll handle it that way.
Will changing my locks change the Shadow Park gate access?
No. Changing your own door locks does not affect the community gate, which has staffed access and is managed separately. Ask whoever runs the community about gate credentials when you move in. We can help with your front door and other exterior doors.
I rent out a property in Cerritos. Should I change locks between tenants?
It is a common practice and a reasonable one, since you cannot be sure every key came back. A rekey is often enough. We cover this on our page for locksmith services for landlords, including doing several units at once.
How many keys will I get, and can I get more?
You will receive new working keys for the locks we changed, and we will tell you how many before we start. If you want more copies later for family members, we can cut them, and we'll show you how to keep the original safe.
How do I know a locksmith is legitimate?
Ask for their California BSIS LCO license number, confirm the company name matches the one you called, and ask for an explanation of the work and quote before it begins. A legitimate company will answer these questions without hesitation.
