When does a lock need replacing instead of fixing?
Most people call us after something has already gone wrong: a key snapped halfway out of the cylinder, a deadbolt that no longer throws all the way, a handle that spins without moving the latch. Some of those problems are cheap to fix and some are not worth fixing at all. Part of our job is telling you honestly which is which, before any hardware comes out of the door.
Lock replacement means we remove the existing lockset, cylinder, or deadbolt and install new hardware in its place. It is different from rekeying, where the lock body stays and only the internal pins change so a different key works. It is also different from repair, where we fix a worn part inside a lock that is otherwise sound. If you are not sure which one you need, the answer usually shows up in the first few minutes of looking at the door.
Replacement is usually the right call in a handful of situations:
- The lock is physically damaged: bent latch, cracked housing, a cylinder that was forced or drilled, or a handle that has pulled loose from the door.
- The mechanism is worn out. Keys stick, turn only with jiggling, or the bolt drags against the strike plate no matter how it is adjusted.
- The hardware is old and builder-grade, and you want a real security lock upgrade rather than another cosmetic fix.
- You have lost track of how many copies of the key exist, and the lock itself is too far gone for rekeying to make sense.
- The finish has failed or the lockset no longer matches the rest of the hardware after a door or remodel project.
- The lock was damaged in an attempted break-in and you want it replaced the same day, not patched.
How does lock replacement work, step by step?
Whether it is a front door lock replacement on a bungalow or a house lock replacement on a back unit, the process follows the same order. We do it this way because skipping the early steps is how people end up with new hardware that does not fit or does not close properly.
- You call (213) 577-1366 and describe the door, the lock, and what happened. A real person answers, at any hour, and we tell you plainly whether replacement, repair, or rekeying sounds like the right path.
- A technician comes to you in one of our mobile service vans, already carrying a range of common deadbolts, knobs, levers, and cylinders, since we cannot know what a door needs until we see it.
- We inspect the door itself, not just the lock. We look at the bore holes, the edge of the door, the strike plate, the frame, and whether the door closes squarely. A new lock on a warped or loose door will fail early.
- We explain what we found and what we recommend, including any lighter-cost option that would still do the job. You decide before we remove anything.
- We remove the old hardware and fit the new lock, adjusting the latch and strike so the bolt throws fully without forcing.
- We test the lock repeatedly with the door open and closed, check every key, and show you how it operates. If the door or frame needs a small correction to work properly with the new lock, we tell you and do it.
- You get the new keys, and we take the old hardware away unless you want to keep it.

Call (213) 577-1366What kinds of locks do we replace for homes and apartments?
Residential lock replacement covers more hardware than most people expect. On a typical house, there may be a deadbolt, a knob or lever set, a side door lock, a garage entry lock, a sliding door latch, and a gate or padlock. They do not all wear out at the same rate, and they do not all need the same grade of hardware.
For the front door, we usually recommend a separate deadbolt with a solid strike plate and long screws that reach the framing, not just the thin trim. Many older doors have a single cheap spring-latch knob doing all the work, which is the first thing to upgrade. If you want a keyless option, a smart lock installation can be paired with a new deadbolt, though we will tell you honestly whether your door and your habits suit it.
For apartment lock replacement, the situation depends on who owns the door. Tenants generally need the landlord's permission before changing locks, and building managers often need a key on file. If you manage rental units, we work with owners and property managers on turnover changes, and our locksmith for landlords page explains how that typically goes. If you are a tenant locked out rather than looking to replace hardware, we handle that too, but it is a different service from this one.
For doors that need more than standard hardware, such as a door facing an alley or a back unit that is hard to see from the street, a high-security lock with a restricted keyway is worth considering. It costs more than a standard deadbolt, and for some doors it is more than you need. We will say so.
- Deadbolts, single and double cylinder, where code and safety allow
- Knobs, levers, and entry sets that match your existing hardware
- Cylinders only, when the lock body is sound but the cylinder is damaged
- Side doors, back-unit doors, and garage entry doors
- Sliding door and patio door locks
- Padlocks and gate hardware
Business lock replacement and security upgrades
Commercial lock replacement is its own category, and we treat it that way. A shop door sees far more cycles in a week than a house door sees in a year, so hardware wears faster. It also tends to need features that residential locks do not offer, such as keyed-alike sets, restricted keys, closers that work with the latch, and exit hardware that meets fire and egress rules.
Storefronts often have narrow aluminum-frame glass doors with their own hardware styles, and those need a technician who knows the difference. If your door is dragging, the latch is sticking, or the cylinder has been tampered with, our storefront lock repair page covers the repair side. When repair is not enough, we replace the lockset and tell you if the door or closer is part of the problem.
A business security upgrade does not have to mean replacing everything at once. Many owners start with the front door and the back door, which see the most risk, then handle interior doors and offices as budget allows. We would rather help you sequence it than sell you a full overhaul in one visit. We also keep careful track of key assignments, so that when an employee leaves you are not left wondering who still holds a way in.

Call (213) 577-1366What affects the cost of lock replacement in Bellflower?
We do not quote prices on a web page, because the honest answer depends on the door in front of us. What we can do is explain what moves the number, so nothing about the quote surprises you.
The biggest factor is the hardware itself. A basic builder-grade deadbolt and a high-security cylinder with a restricted keyway are very different products. The same goes for a plain knob set versus a heavy-duty lever, or a smart lock versus a mechanical one. Grade and brand matter, and a better-built lock usually holds up longer, which is worth weighing against the upfront cost.
The second factor is the condition of the door and frame. If the bore holes fit standard hardware and the frame is solid, installation is simple. If the door is cracked, the frame is split from a past forced entry, or the holes are the wrong size, there is extra work involved, and we tell you that before starting. Older wood doors are more likely to need small adjustments.
Other factors are how many locks are being replaced at once, whether they need to be keyed alike, how many keys you want cut, and whether the work happens during normal hours or in the middle of the night. After-hours emergency work generally costs more than a scheduled visit, and we say that plainly rather than hiding it.
If cost is the main concern, ask us for the more economical route. Sometimes that is replacing just the cylinder, sometimes it is a lock repair, and sometimes it is rekeying a lock that is still in good shape. We will not push a full replacement when a smaller job solves the problem.
Lock replacement in Bellflower: bungalows, back units, and mobile homes
Bellflower grew out of a dairy and farm town, and a lot of the housing reflects that. Much of it is 1940s and 1950s cottages and bungalows, and the city has an unusually high number of rear units, duplexes, and front-house/back-house lots. For lock replacement, that matters in a few specific ways.
On a lot with a front house and a back house, there may be several entry doors on a single property, often with hardware installed at different times by different owners. When a new tenant moves into the back unit in the 90706 ZIP code, or the owner decides to separate access, we often replace the back-unit lockset and sometimes the side gate hardware so each unit has its own keys. The same goes for duplexes, where shared side doors and separate front doors can end up on a confusing mix of keys.
Older wood doors in these homes are another reason to look at the door, not just the lock. Bellflower sits on the inland coastal plain with a morning marine layer, and damp winter mornings can swell older wood doors and frames. Corrosion is minor here, so the problem is rarely rusted hardware. It is more often a door that sticks in the frame, a latch that no longer lines up with the strike, or a deadbolt that binds until the weather dries out. We check for that during installation so your new lock does not start fighting the door the first wet week.
Apartment complexes and several mobile home parks push the renter share up, and each has its own pattern. Near the Artesia and Alondra boulevard corridors, we see apartment doors where the lock was changed once by a previous resident and nobody can say who holds keys. In mobile home parks, hardware replacement is common because the doors and locks are often lighter-duty and wear out. We carry hardware that fits those doors.
Downtown Bellflower along the Bellflower Boulevard core has newer mixed-use buildings alongside older storefronts, so we work on both residential-style and commercial doors there. Along the Rosecrans Avenue and Woodruff Avenue corridors, and around the Somerset Boulevard area, the mix is mostly single-family and small multi-unit properties. Homes near Simms Park, Caruthers Park, and the Bellflower Bike Trail often have side gates and padlocks that see regular use, and those are worth replacing before they fail. If you back onto the bike trail, a sturdier gate latch and a shielded padlock are a sensible upgrade.
Our storefront is at 10740 Wilshire Blvd in Westwood, about 25 miles from Bellflower, and our vans cover the city as part of the 140 cities we serve across Los Angeles and Ventura counties. If you would rather have a technician come to you, see our mobile locksmith service.

Call (213) 577-1366Why call Wilshire Lock & Key for a replacement?
There are plenty of ways to find a locksmith, and not all are equal. Here is what we can honestly say about ourselves.
We have been in business since 1987. That is not a slogan; it means David and the team have seen decades of door types, hardware generations, and ways locks fail. David is the owner and lead technician, and he oversees the work our company does.
We are one company. When you call (213) 577-1366, you are talking to us, not a national call center that sells your job to whichever subcontractor will take it. That matters for replacement work because the person who gives you advice on the phone is connected to the person who shows up at your door.
We have both a physical storefront and mobile service vans. A real storefront means there is a place with a real address that you can verify, and the vans mean we can come to you.
We answer the phone 24 hours a day, 7 days a week, year-round. If your lock was damaged during a break-in at midnight, you do not have to wait until morning to find out what your options are.
What should you ask any locksmith before replacing a lock?
Whoever you hire, a few questions protect you. California requires locksmith companies to hold a BSIS LCO license, issued through the Bureau of Security and Investigative Services. Ask any locksmith for their license number and check that it is current before they start work. A reputable company will give it to you without hesitation.
Ask what brand and grade of lock they plan to install, and ask for the full price before work begins, including any after-hours charge. Be wary of anyone who quotes a very low figure over the phone and then raises it once they are at your door. Ask whether the technician will check the door and frame, not just swap the lock. And ask whether a simpler option, like repair or rekeying, would solve the problem.
Finally, keep the old hardware if you want to, and make sure you receive all the new keys. A well-run job ends with you knowing exactly how many keys exist and who has them.
Frequently asked questions
Can you replace a lock the same day I call in Bellflower?
In most cases, yes. We answer the phone at (213) 577-1366 around the clock, and our mobile vans carry common deadbolts, knob sets, and cylinders. If your door needs an unusual or specialty lock, we may need to order it, and we will say so on the call rather than leave you guessing.
Should I replace my lock or just rekey it?
If the lock works smoothly and is in good shape, rekeying is usually the more economical route, since it changes which key works without new hardware. If the lock is damaged, worn, or very low quality, replacement makes more sense. Our lock rekey page explains the difference in more detail.
How do I know if my front door lock is worn out?
Common signs include keys that stick or need jiggling, a deadbolt that turns stiffly or only partway, a handle that wobbles or spins loose, and a latch that no longer lines up with the strike plate. If you notice any of these, it is worth having a technician look before the lock fails completely.
How much does lock replacement cost in Bellflower?
We do not give a number on a web page because the cost depends on the lock grade, how many locks are involved, the condition of the door and frame, and whether the work is during normal hours or after hours. Call (213) 577-1366, describe the door, and we will explain the options and what drives the price before any work starts.
Do I need my landlord's permission to replace my apartment lock?
Usually, yes. Tenants generally need to talk to the landlord or property manager first, since the building may need a key on file. If you are a property owner or manager, we can replace locks between tenants and keep track of the keys for you.
Can you replace locks on a mobile home door?
Yes. Mobile home doors often use lighter-duty hardware and different door thicknesses, so we match the lock to the door rather than forcing a standard residential product. We can replace the lockset, the deadbolt, or both.
My wood door sticks when it is damp. Will a new lock help?
A new lock alone will not fix a swollen door. Older wood doors and frames can swell on damp winter mornings, which makes the latch bind. We check the door fit when we install the lock, adjust the strike where needed, and tell you if the door itself needs attention.
Do you replace business locks and handle security upgrades for shops?
Yes. We replace locks on storefronts and offices, and we can help you plan a business security upgrade in stages, starting with the doors that carry the most risk. For repair-only needs on shop doors, see our storefront lock repair service.
Will the new lock match my existing hardware?
Often we can match finish and style closely, especially for common lock types. If your existing hardware is discontinued or unusual, we will show you the closest options and explain any differences before we install.
