Should you rekey or replace your locks?
Most people who call about a lock change need one of two jobs, and they are not the same job. Rekeying keeps the lock you already have and changes the inside of it, so the old keys stop working and a new key takes over. Replacing removes the lock and puts different hardware on the door. Either way, you end up with the thing you actually care about: keys that other people may be holding no longer open your door.
Rekeying is usually the more economical route when the lock is in good working shape, because you are not paying for new hardware. Replacement makes more sense when the lock is worn, damaged, loose in the door, mismatched with the other locks, or when you simply want a different style or a stronger grade. We look at the lock on your door before we recommend anything, because the right answer depends on what is physically there, not on a script.
If you already know you want one or the other, we have more detail on lock rekeying in Compton and lock replacement in Compton. If you are not sure, that is exactly what this page is for.
- Rekey when the hardware is sound, the finish is acceptable, and your only concern is who holds keys.
- Replace when the lock is worn, sticks, has been forced, doesn't match your other doors, or you want a different grade or look.
- Either way, every lock on the property can be set to work with one key, or kept separate if you prefer.
When does it make sense to change locks?
The obvious moment is a lost or stolen key, but it is rarely the only one. A lock change is sensible any time you cannot say with confidence who has a working key to your door. That uncertainty is what you are fixing, and it shows up in more everyday situations than people expect.
- You bought a house and have no idea how many keys the previous owner, agents, contractors and relatives still hold.
- You are renting or moved into a place and the last tenant's keys were never accounted for.
- A roommate, partner, house sitter, cleaner or contractor moved on and you would rather not rely on getting every key back.
- There was a break-in or attempted break-in, and the lock or the door around it took damage.
- Your key has been copied so many times, by so many people, that you have lost track.
- A lock has started to stick, spin, or feel loose, and you would rather deal with it before it fails on you.

Call (213) 577-1366Locksmith for a new house: what to do after you get the keys
Getting a locksmith for a new house is one of the first practical things to do after closing, and it is usually quick compared with everything else on the list. The previous owner may have handed over every key they knew about. They cannot account for the copy a neighbor made, the one a dog walker kept, or the one that sat in a realtor lockbox. Changing the locks means that question stops mattering.
When we walk a new home, we start with the doors you use and then check the ones you forget about. A common mistake is to do the front door and overlook the rest. Think about every way into the property, and every lock that matters to you.
If your new place has a basic latch where you would like a proper deadbolt, that is a separate upgrade, and we cover it under deadbolt installation. If you are leaning toward keyless entry, our page on smart lock installation explains when that is a good fit and when a traditional lock is the sounder choice.
- Front door and any secondary entry doors
- Back door, patio door, and the door from the garage into the house
- Security screen doors that have their own lock
- Side gates, garage doors, sheds and any outbuildings
- Mailbox, if it has a lock you did not receive keys for
How do we change your locks, step by step?
The work is straightforward, and we explain each step as we go so nothing is a surprise when you get the keys.
- You call (213) 577-1366 and tell us what happened: new home, lost keys, a breakup, a break-in, or just peace of mind. We ask how many doors and what kind of locks you have.
- We come to you in a mobile van. Our storefront is at 10740 Wilshire Blvd in Westwood, and the van brings the tools and common hardware to your door.
- We look at each lock in person: brand, condition, how it sits in the door, and whether the door and frame line up properly.
- We tell you what we recommend for each door, rekey or replace, and why. You hear the cost before work starts, and you decide.
- We do the work. For a rekey, we change the internal pins and cut new keys. For a replacement, we remove the old lock and fit the new one so the bolt throws cleanly into the strike.
- We test every lock with the door open and closed, from both sides, with the new keys. We also confirm the old key no longer works.
- We hand over the keys, point out anything on the door that needs attention, and answer questions about extra copies.

Call (213) 577-1366What affects the cost of a lock change?
We won't quote a number on a web page, because the honest price depends on your actual doors. What we can do is tell you what moves it up or down, so you can judge any quote you receive from anyone.
- Rekey or replace: rekeying usually costs less because you are not buying new hardware, as long as the existing lock is in good condition.
- Number of locks: a single door is a short visit; a whole house with a garage entry, side door and screen doors takes longer.
- Lock grade and type: a basic knob set, a standard deadbolt and a high-security cylinder are different products with different costs.
- Condition of the door and frame: if the door has swelled, sagged or been kicked, we may need to fix alignment so the new lock works properly.
- Key requirements: matching all locks to one key, restricted keys, or a larger number of copies adds to the job.
- Time of day: after-hours and emergency calls involve different scheduling than a planned weekday visit.
- Travel: Compton is about 20 miles from our Westwood base, which is part of how we plan the visit.
Changing locks in Compton homes: what we see locally
Compton's housing runs from 1920s bungalows near downtown to the late-1940s and 1950s tract homes that fill most of the city. Housing is predominantly single-family, with apartments along the major corridors. That mix shapes how we approach a lock change in places like Downtown Compton, Sunny Cove and Leland, and in ZIP codes 90220, 90221 and 90222.
Houses of that age have usually seen several owners, and over the decades their hardware tends to be a patchwork: one lock from one era, a deadbolt added later, a back door that was never touched. That is why a rekey is often a good fit for 1940s and 1950s tract houses. If the existing locks are sound, you can bring every door onto a fresh set of keys without replacing everything. Where a lock is worn out, we replace that one and leave the rest.
Security screen doors and window bars are common in Compton, and they matter here. A screen door with its own lock is one more key someone may hold, so we ask about it at the start and set it up to match your main keys or keep it separate, whichever you prefer.
The climate is mild, with regular morning marine layer. Corrosion is minor this far from the shoreline, so locks are not usually failing from weather. Older wood doors, however, can swell in damp winter months, and a swollen door makes a perfectly good lock feel stiff or misaligned. We check whether it is the lock or the door before deciding to swap hardware, so you are not paying to replace something that was not the problem.

Call (213) 577-1366Richland Farms and rental properties: lock changes with more than one door
Richland Farms is unusual. It is an agricultural-zoned district of large lots with barns, corrals and horse-keeping, a legacy of the land terms set when Griffith D. Compton donated the land at the city's founding. If you buy there, a lock change often covers more than the house. You may inherit a pasture gate, a barn, and outbuildings, all with locks and keys of unknown origin. We can change the house and the outbuildings so that they work together on one key, or set them up separately if you would rather the barn key never opens the house.
For landlords and property managers with apartments along Long Beach Boulevard, Compton Boulevard or Rosecrans Avenue, a lock change between tenants is routine and worth doing every turnover, since you cannot know who kept a key. We keep records of how each unit is keyed so that your next turnover is simpler. Our page for landlords in Compton covers that work in more detail.
If you are locked out of a home right now rather than planning a lock change, that is a different job, and our house lockout service is the page to read.
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. Compton is one of them. We run a real storefront at 10740 Wilshire Blvd in Westwood along with mobile service vans, so you are dealing with a shop that has an address and a phone that someone answers.
When you call (213) 577-1366, you reach us, not a call center that sells the job to whoever is available. One company handles the call and the work, with no dispatch middlemen in between. David, the owner and lead technician, oversees the work. You will not be passed around.
We answer the phone 24 hours a day, seven days a week, year-round, which matters for lock changes more than people expect. A break-in at night, a key lost on a weekend, or a move-in that lands outside business hours should not have to wait. If your situation is urgent, see our emergency locksmith service in Compton. If you just need extra keys cut after the change, we can do that too through key duplication.
How do you check a locksmith before you hire one?
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services (BSIS), known as an LCO license. Ask any locksmith you are thinking of hiring for their license number, and check it with BSIS yourself. A reputable company will give it to you without hesitation.
A few other signs are worth watching. A legitimate company gives you a clear explanation of what it will do and why before it starts. It tells you the cost for your specific job and does not push you to replace hardware that works. It also tells you its real business name and address when you ask. If someone is vague about any of that, call another company.
Frequently asked questions
What is the difference between changing locks and rekeying?
Changing locks is the broader term. It can mean rekeying, where we keep your lock and alter it so a new key works and the old ones do not, or replacing, where we install different hardware. Rekeying is usually the more economical route when the lock is in good shape. We'll look at your doors and tell you which makes sense.
Should I change the locks after buying a house in Compton?
Yes, it is a sound habit. You cannot know who still has a key from the previous owner, their agents, contractors or relatives. Changing or rekeying the locks resets that. It is especially worth doing on older homes, where hardware has often been mixed over the years and nobody kept a full record of keys.
Can you change all my locks to use one key?
Usually yes. We can set the front door, back door, garage entry and often the screen door to work with a single key. Some locks cannot be matched, depending on their make and condition, and we will tell you so up front. If you want certain doors kept separate, such as a barn or outbuilding, we can do that too.
How long does it take to change the locks on a house?
It depends on how many locks there are and what shape the doors are in. A single door is a short visit. A whole house with several entries, screen doors and outbuildings takes longer. If a swollen or misaligned door needs adjustment, add time for that. We tell you what to expect once we have seen the doors.
Do I need new locks if I lost only one key?
Not always. If you are confident the key was lost at home or is truly gone, you might be fine. If it went missing with your address attached to it, or you are simply unsure, a rekey is usually a more economical way to settle the question than replacing hardware. We can talk through the situation and give you an honest opinion.
Can you change locks at night or on weekends in Compton?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, seven days a week, year-round. We come to you in a mobile van. After-hours calls are scheduled differently from planned daytime visits, and we explain that when you call, so the cost is clear before we start.
My door sticks in winter. Do I need a new lock?
Possibly not. Older wood doors can swell in damp winter months, and a swollen door makes a good lock feel stiff. We check whether the problem is the lock or the door before suggesting replacement. Sometimes the fix is adjusting the door or strike plate, which means you are not paying for hardware you did not need.
Can you change locks on barns and gates at Richland Farms?
Yes. Lock changes on pasture gates, barns and outbuildings are part of what we do on larger properties. We can set them up to share a key with the house or keep them separate. Exposed hardware outdoors varies a lot, so we look at what is installed before suggesting rekeying or replacement.
How do I know a locksmith is legitimate?
Ask for their California BSIS LCO license number, which the state requires of locksmith companies, and verify it yourself. Also ask for a clear explanation of the work and the cost before they start. A company with a real address and a phone that answers is a better sign than an anonymous listing.
