What is your lock actually doing?
Most people call us with a symptom, not a diagnosis. The lock worked fine for years and then one morning the key will not turn, or the deadbolt only throws if you lift the door, or the knob wobbles in your hand like a loose tooth. Each of those symptoms points to a different cause, and the cause decides whether a repair makes sense.
Lock repair is the work of finding the worn, bent, dirty, or loose part inside or around the lock and fixing that part, so the hardware stays on your door and keeps using your existing keys. Here are the situations we see most often with residential and small commercial doors:
- Lock not turning: the key goes in but the cylinder will not rotate, or it turns only with force. Usually worn pins, a dirty cylinder, or a bolt that no longer lines up with its strike plate.
- Key stuck in lock: the key will not come back out. Often a worn key, a damaged pin stack, or debris. Do not yank it. If the key has actually snapped, that is a separate job, covered on our broken key extraction page.
- Jammed door lock: the latch or bolt sticks halfway, so the door will not open or will not lock. Frequently a warped door, a loose strike plate, or a spring that has given out.
- Loose door lock: the knob, lever, or deadbolt body spins or shifts. Usually backed-out screws, a stripped mounting hole, or a worn spindle.
- Latch repair: the latch does not retract fully, does not catch, or rattles in the frame. Often a weak spring or a strike plate that has drifted out of position.
- Damaged or broken lock: forced entry attempts, a kicked door, or a cracked housing. Some of these are repairable, some are not, and we will tell you which.
- If a jammed lock has left you standing outside, our house lockout service is the starting point, and we can often repair the lock once you are back inside.
Should you repair the lock or replace it?
This is the question that matters most, and it is where an honest locksmith earns the call. Replacement is sometimes the right answer. But a lot of locks that look finished are one worn part away from working again, and swapping the whole assembly just because it is faster for the installer is not how David runs this shop.
We lean toward repair when the core hardware is solid: a heavy, well-made deadbolt with a sticking cylinder, a mortise lock with a worn spring, a knob with a loose mount. We lean toward replacement when parts are no longer available, when the lock is built so cheaply that repairing it would only buy a short stretch of use, or when the security grade is too low for the door it is protecting.
Here is how we think about the decision, in plain terms:
- Repair makes sense when the failure is a single wearing part, a mounting problem, an alignment problem, or a cleaning and lubrication problem.
- Replacement makes sense when the body is cracked or bent, the internals are badly worn throughout, replacement parts cannot be sourced, or the lock is not strong enough for what it guards. If that is where you land, see our lock replacement service.
- Rekeying is a third option people forget. If your lock works but you have lost keys or had a tenant move out, you may not need repair at all. Our lock rekey page explains when changing the pins is enough.

Call (213) 577-1366How does a lock repair visit work?
Whether we come to you in a mobile van or you bring a removable lock to our Westwood storefront at 10740 Wilshire Blvd, the process is the same. We do not start by pulling parts off your door. We start by finding out what is really wrong.
- Call (213) 577-1366. A person answers around the clock, every day of the year. Tell us what the lock is doing, what kind of door it is on, and whether you can still get in and out.
- We talk through the symptom with you. A lot of the time the description alone tells us which parts to bring and whether the job is repair, replacement, or something else.
- We inspect the lock on the door. That means testing the key, operating the bolt and latch, checking the strike plate, and looking at how the door sits in its frame, because a lock is often blamed for a door problem.
- We explain what we found and what your options are before any work begins, including the repair route, the replacement route, and what each is likely to involve.
- We do the repair: cleaning and lubricating the cylinder, replacing worn pins, springs, or cams, tightening and re-seating hardware, realigning the strike, or rebuilding the mechanism.
- We test everything with your actual keys, from both sides of the door, several times, and then we confirm the door locks and unlocks smoothly before we leave.
What kinds of locks do we repair?
Different locks fail in different ways, and a repair that works on one type is wrong for another. These are the types we handle most.
Deadbolt repair. Deadbolts are the lock most people rely on, and also the one most likely to get stiff because it works against a door that has moved over the years. We check the bolt throw, the cylinder, the thumb-turn, and the strike alignment. If you are considering adding a deadbolt where there is none, that falls under deadbolt installation, not repair.
Mortise lock repair. A mortise lock sits in a deep pocket cut into the edge of the door and combines the latch, deadbolt, and trim in one body. You find them mostly on older and heavier doors. They are very repairable because they are built from individual springs, levers, and cams, and many failures come down to one worn part. They also reward careful work, since forcing one can break the case.
Knobs, levers, and latches. Loose knobs, sagging levers, and latches that do not retract are some of the most common calls, and often the least expensive to fix. A new spring, a re-set spindle, or a proper set of mounting screws is frequently all it takes.
Security screen door locks. Many homes here have a security screen door in front of the main door. Its latch gets bent, rusted at the strike, or knocked out of line, and a screen door that will not latch properly defeats the point of having it.
Small commercial doors. We also do commercial lock repair for offices, clinics, and shops, including cylinders, latch sets, and exit hardware. For wider business needs, see our commercial locksmith service.

Call (213) 577-1366How much does lock repair cost in Willowbrook?
We will not quote a number on a web page, because a number given without seeing the lock is a guess, and guesses are how customers end up surprised. What we can do is tell you exactly what moves the price, so nothing about the quote feels like a mystery.
Lock repair is usually the more economical route compared with replacing hardware, especially when the lock is good quality. But the final figure depends on a handful of things:
- The type and quality of the lock. A standard knob is a different job from a heavy deadbolt or a mortise body with specialty parts.
- What has failed. A loose mounting screw and a worn internal cam are very different amounts of work and parts.
- Parts availability. Common hardware is easy to source. Older or discontinued models may take more searching, or may tip the decision toward replacement.
- Whether the problem is really the door. If the door has dropped or the frame has shifted, the fix includes alignment work, not just lock work.
- Time of day. A call in the middle of the night is a different situation from a scheduled daytime visit, and we will explain that up front.
- Location and travel. We come to you in a mobile van, and Willowbrook is about 18 miles from our Westwood base, so distance is part of the picture.
- Once we have looked at the lock, you get a clear explanation of the work and its cost before we begin. If the repair is not worth doing, we will say so rather than do it anyway.
What does lock repair look like around Willowbrook?
Willowbrook is an unincorporated Los Angeles County community covering ZIP codes 90059, 90061, and 90222, and its housing is a mix that shapes the kind of repairs we are asked about. Many streets hold small single-family homes from the 1920s through the 1950s, and older properties often carry aging hardware. A lock that has been on a door for decades has had thousands of turns, plenty of paint, and probably a door that has shifted a little. That is exactly where repair beats replacement: the lock body may be fine, but a spring, a strike plate, or a set of screws has given up. Security screen doors are common here too, and their latches take a lot of daily abuse.
Newer county-supported affordable and senior housing has been built around the revitalized Martin Luther King Jr. medical campus district on 120th Street, and multifamily buildings cluster near the transit and commercial corridors. For those buildings, a stiff or loose lock is more than an inconvenience, because a resident who cannot easily turn a key or work a lever is a resident who may not get in or out safely. Those repairs matter, and we treat them accordingly.
Around the Martin Luther King Jr. medical campus, clinics and medical offices rely on doors that open and lock reliably, and a failing latch or cylinder on a clinic door is something that should be dealt with quickly. Along the Wilmington Avenue and El Segundo Boulevard corridors, storefront locks take heavy daily use, and a sticking cylinder on a shop door is a common reason for a call. For that kind of work, our storefront lock repair page goes deeper into front-of-shop doors and gates.
Down by the Rosa Parks Station area and the Imperial Highway corridor, a lot of people park and ride Metro. If your car door lock or key gives you trouble there, that is automotive work, and our car lockout page is the place to start.
On the climate side, Willowbrook is a flat coastal plain with a morning marine layer and mild temperatures all year. Salt-air corrosion is not a significant factor this far inland, so locks here rarely fail from rust the way they might near the beach. They fail from age, daily use, door movement, dirt in the cylinder, and years of worn keys. That makes most Willowbrook lock problems very fixable.

Call (213) 577-1366Why call Wilshire Lock & Key for lock repair?
We have been in business since 1987, and we serve 140 cities across Los Angeles and Ventura counties. That is a long time to see every way a lock can fail, and it matters for repair work more than for any other kind, because repair depends on recognizing what is wrong quickly and knowing what a part should feel like when it is right.
We are a single company, not a dispatch service. When you call (213) 577-1366, you reach us, and the person who arrives works for us. You are not handed off through a chain of middlemen who each take a share and none of whom answer for the work. We have a storefront on Wilshire Boulevard in Westwood as well as mobile service vans, so we can bring the work to your door or take on removable hardware at the shop.
David, the owner and lead technician, oversees the work. That is why we are comfortable telling you when a repair is not worth doing. A locksmith who only earns money from replacements has a reason to talk you into one. We would rather fix the lock you have when that is the sensible answer, and tell you plainly when it is not.
The phone is answered 24 hours a day, seven days a week, all year. A lock that will not work does not wait for business hours.
Is the locksmith you call properly licensed?
Ask. California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license, and any locksmith you hire should be willing to give you that number without fuss. It is a reasonable question, and a company that dodges it is telling you something.
Lock repair puts someone inside the security of your home or business, so you are entitled to verify who they are. Check the license number with the state, ask for a clear explanation of the work, and be wary of anyone who will not explain what they plan to do before they do it.
What can you try before you call?
There are a few safe steps that sometimes solve the problem, and a few habits that make it worse.
First, do not force it. Leaning on a key that will not turn is how keys snap inside cylinders, which turns a repair into an extraction. If the key resists, stop and look at the cause.
Second, try the door itself. Press or lift the door slightly while you turn the key. If that makes the lock work, the problem is probably alignment between the bolt and the strike plate, not the lock itself. That is useful to know and quick to fix.
Third, check for loose screws. A loose knob or deadbolt often just needs the mounting screws snugged up. If the screws just spin without tightening, the holes are stripped and the fix needs more than a screwdriver.
Fourth, be careful with lubricant. A small amount of dry graphite or a lock-specific lubricant can free a sticky cylinder, but heavy oil attracts dust and can gum up the pins over time. If you have already sprayed something in there, tell us when we arrive.
If none of that helps, call. The sooner a worn part is addressed, the less likely it is to take other parts with it.
Frequently asked questions
Can you fix a lock that will not turn instead of replacing it?
Often, yes. A lock that will not turn is usually caused by worn or dirty pins, a misaligned bolt, or a bent part rather than a completely dead lock. We inspect it first, explain what we find, and repair it when the hardware is worth saving.
What should I do if my key is stuck in the lock?
Stop pulling and do not twist harder, since that can snap the key. Call us at (213) 577-1366 and describe what happened. If the key is simply stuck, we can usually free it and repair the cylinder. If it has broken off, that becomes extraction work.
How do I know whether my door lock needs repair or replacement?
If one part has worn or the lock has come loose, repair is usually enough. If the body is cracked, the internals are worn throughout, parts cannot be found, or the lock is too weak for the door, replacement is the better call. We tell you which one it is before starting.
Do you repair deadbolts and mortise locks?
Yes. Deadbolt repair and mortise lock repair are a regular part of what we do. Mortise locks are built from individual springs, levers, and cams, so many of them can be restored by replacing a single worn component rather than the whole lock.
Do you handle commercial lock repair in Willowbrook?
We do. Offices, clinics, and shops all rely on locks and latches that get heavy use, and we repair cylinders, latch sets, and related door hardware. Commercial and residential lock repair follow the same approach: diagnose first, explain the options, then fix what is worth fixing.
Will my existing keys still work after the repair?
In most repairs, yes. If we repair the lock rather than replace it, your current keys normally keep working. If the repair involves changing the internal pins, we will tell you in advance whether your keys will change and by how much.
Can you repair the lock on a security screen door?
Yes. Security screen doors are common in Willowbrook, and their latches often get bent, loose, or knocked out of alignment. We can repair or realign the latch and strike, or tell you honestly if the whole set should be swapped out.
Is it safe to use WD-40 or oil on a sticky lock?
It is better to avoid heavy oils. They can attract dust and gum up the pins over time. A small amount of dry graphite or a lubricant made for locks is the safer choice. If a lock is still sticking after that, it likely needs a proper repair.
Can I call at night about a lock that will not work?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, all year. If the lock can wait until morning we will help you plan for that, and if it cannot, we will talk through how to get your door secured.
