What counts as lock repair, and when is it the right call?
Lock repair means getting the lock you already own to work properly again. That can be as small as cleaning out a cylinder and adjusting a strike plate, or as involved as disassembling a mortise body and replacing a worn internal part. The idea behind it is simple: most locks fail in one small place, and the rest of the hardware is often perfectly good. Replacing an entire deadbolt because one spring has given out, or because the door has shifted a sixteenth of an inch, is usually the more expensive way to solve a small problem.
We've been doing this work since 1987, and the pattern holds across decades and hardware generations. A lock that sticks, drags, or needs a shoulder against the door is almost always telling you something specific. Our job is to read that message, find the actual fault, and fix that fault. Sometimes the honest answer is that the lock is past saving, and we'll say so. But repair is where we start, because it's frequently the more economical route and it keeps your existing keys, finish, and hardware style intact.
What situations lead people to call for lock repair?
Almost nobody calls a locksmith for repair on a calm afternoon with nothing wrong. The call usually comes when something has just stopped working, often at an inconvenient moment. These are the situations we see most often, and each one points to a different kind of fault.
- The key goes in but won't turn, or turns only with pressure and wiggling.
- The key is stuck in the lock and won't come back out.
- The key snapped and part of it is still inside the cylinder.
- The deadbolt throws only partway, or the bolt won't line up with the hole in the frame.
- The doorknob or lever spins freely, feels loose, or wobbles on the door.
- The latch won't retract, so the door stays shut, or it won't catch, so the door drifts open.
- The lock works from one side but not the other.
- The door was forced, kicked, or pried, and the lock or strike area is bent or cracked.
- An old mortise lock has become stiff, gritty, or unreliable.
- A commercial storefront or office door no longer latches reliably at closing time.
How is a lock repair actually done, step by step?
A good repair is mostly diagnosis. The tools matter, but knowing where to look matters more. Here's the general sequence we follow, though the details change with the hardware in front of us.
- Listen to the problem. When did it start, did anything change first (a new key, a door that was slammed, weather, a break-in attempt), and does it fail every time or only sometimes? Those answers narrow the cause before we touch anything.
- Test the lock with the door open. We operate the bolt or latch by hand with the door open and the key in use. If it works freely open and binds when the door is closed, the fault is probably alignment, not the lock itself.
- Test it with the door closed. We watch how the bolt meets the strike plate and the frame. Scuff marks, a bolt that rides the edge of the hole, or a latch that clicks against metal instead of sliding in all tell the story.
- Check the key. A worn, bent, or poorly cut key can mimic a failing lock. We compare it against a known-good key where one exists, because swapping a key is a far lighter fix than opening a cylinder.
- Remove and open the hardware if needed. We take the lock off the door, separate the cylinder from the body, and inspect pins, springs, cams, tailpieces, and latch mechanisms for wear, debris, corrosion, or breakage.
- Clean, correct, and replace only what's failed. That might mean clearing packed grit, replacing a broken spring or cam, re-pinning a cylinder, tightening or re-seating loose mounting, or correcting a bent part.
- Fix the door-side cause. If the real culprit is a sagging door, a hinge that's pulled loose, or a strike plate set slightly off, we correct that too. Otherwise the repaired lock would fail again.
- Reassemble and test thoroughly. We cycle the lock repeatedly with the door open and closed, and check every key you plan to keep using before we leave.

Locks are small mechanical devices that get used thousands of times, usually with no maintenance at all. Most failures trace back to a short list of causes.
Wear is the plainest one. Brass pins and keys wear each other down, so a lock that has been in service for years may start to feel rough or need extra jiggling. Dirt and debris contribute as well; fine dust and grit gather in the keyway and pin chambers, and over time they thicken any old lubricant into a gummy film. Heavy-handed fixes make it worse, particularly the wrong lubricant sprayed in from a hardware-store can, which can attract more dust.
Alignment is the second big category, and it's the one people overlook. Doors move. Hinges loosen, wood swells and shrinks, frames shift, and a deadbolt that used to slide cleanly now catches on the edge of the strike. The lock is blameless; the door has simply moved a little. Forcing the key harder in that situation is how keys get bent or snapped.
Finally there's damage: forced entry attempts, a key snapped in the cylinder, a door slammed so hard that internal parts have shifted, or a lock that has been painted over. Each leaves its own signature, and each calls for a slightly different repair.
How does the type of lock change the repair?
Not every lock is repaired the same way, and the hardware is what shapes the job.
- Deadbolt repair: Most residential deadbolts are straightforward cylinder-and-bolt assemblies. Typical faults are a worn cylinder, a loose or misaligned bolt, a damaged thumbturn, or a strike plate that no longer meets the bolt cleanly. Many can be repaired on site.
- Knobs and levers: Loose or spinning handles are often a failed set screw, a stripped mounting, or a broken internal spring. These are frequently quick to restore, though very inexpensive builder-grade sets may be nearer to the end of their life.
- Mortise lock repair: Mortise locks sit inside a pocket cut into the edge of the door and contain a more complex body of springs, levers, and a latch. They're common in older homes and some commercial doors. They're repairable, often for decades more, but they require patience and familiarity. Parts can be hard to find, so sometimes a part is cleaned, reshaped, or fabricated instead of ordered.
- Latch repair: Spring latches and deadlatches fail when springs weaken, or when the latch face and strike drift out of alignment. Fixing the alignment is often the whole job.
- Commercial hardware: Heavier-duty cylinders, exit devices, and storefront locks are built for constant use, which means wear in different places and different parts. Business doors also have the added pressure of needing to be secure by closing time. If a business door is failing, tell us that when you call.
- Mailbox, cabinet, and gate locks: Smaller cylinders and outdoor hardware have their own habits, especially weather exposure. For swing and slide gates specifically, see our gate lock repair page.
- Vehicle locks and keys: Automotive locks and keys vary by make, model, and year, and some involve electronics. We confirm what a specific vehicle needs by VIN or in person, and some situations are dealer-only. We'll tell you plainly when that's the case instead of guessing.

Call (213) 577-1366What can lock repair not fix, and when is something else the right call?
Repair is our first choice, but it isn't always the right one, and we'd rather say so than sell you a job that won't last. Several situations point elsewhere.
If the lock body is cracked, severely corroded, or has been so badly forced that its internal structure is compromised, repair may only be temporary. In that case, lock replacement is the more sensible route. The same is true if the hardware is so worn or so low-grade that fixing it just means a different part will fail next month.
If the lock itself works perfectly but you're worried about who else might hold a key, such as after a move, a breakup, a departed tenant, or a lost key, you don't need a repair at all. Lock rekeying changes the internal pinning so old keys stop working, without replacing the hardware.
A repair also can't change the grade of a lock. If your concern is that the existing deadbolt is simply not strong enough, that's an upgrade conversation, not a repair one. And a repair can't make a failing door or frame secure; if the wood around the strike is split, the frame itself needs attention. We'll tell you when that's what we're seeing, and we'll tell you if a repair would just be a short-lived patch.
What affects the cost of a lock repair?
We don't quote numbers on a web page, because honest pricing depends on what's actually wrong. What we can do is explain the factors that move the cost, so nothing about the quote surprises you. You can also read more on our pricing page.
The biggest factor is the nature of the fault. Cleaning a cylinder or adjusting a strike plate is a light job; rebuilding a mortise body or repairing damage from forced entry takes more time and parts. The type of hardware matters too. Common residential deadbolts have easy-to-source parts, while older, specialty, or high-security hardware may need special sourcing or extra labor.
Timing and location play a part: a late-night emergency call involves different logistics than a scheduled daytime visit, and distance across our service area can factor in. The number of locks involved matters, as does whether a door or frame needs correcting alongside the lock.
One more consideration: repair is not automatically the lighter-cost option. When a lock is badly worn, replacing it can be usually more economical than a repair that won't last. We'll lay out both honestly and let you choose.

Call (213) 577-1366Why call Wilshire Lock & Key for lock repair?
We've been in business since 1987, and that history shows up in the details: we've worked on everything from old mortise sets to modern cylinders, and we recognize failure patterns quickly. Our storefront is at 10740 Wilshire Blvd in Westwood, and we also run mobile service vans, so repair can happen at your door or, for removable hardware, at our shop.
When you call (213) 577-1366, you're reaching one company, not a dispatch center that sells your job to whoever's nearest. The phone is answered 24 hours a day, 7 days a week, year-round. David, the owner and lead technician, oversees the work, and that means someone with a stake in the result is behind every repair.
One practical note on choosing any locksmith: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they start work. It's a fair question and a good one to make a habit of. Also be wary of anyone who wants to drill out or replace your lock before they've even looked at it; sometimes it's necessary, but it shouldn't be the opening move.
Where do we provide lock repair?
We serve 140 cities across Los Angeles County and Ventura County, from our Westwood storefront outward. The full list is on our locations page. If you want to see how the service looks in a specific area, our city pages go into local detail, including lock repair in Los Angeles and lock repair in Santa Monica.
This page is about the craft itself, so what's written here applies across the whole coverage area. The hardware, the failure patterns, and the repair process are the same whether the door is at a house, an apartment, or a business. If you're not sure whether we cover your address, just call and ask.
What should I do before the locksmith arrives?
A few small steps can protect your lock and make the repair easier.
- Stop forcing it. Extra pressure on a stuck or stiff key is how keys snap and cylinders get damaged.
- Don't spray heavy oil into the keyway. It can gum up the pins and turn a simple repair into a harder one.
- Note exactly what's happening: which side, whether it's the key or the door, whether it's sudden or gradual.
- If a key has broken, don't try to dig out the piece with improvised tools. Leave it for us.
- Gather every key you use for that lock so we can test each one.
- If the door won't secure and you have to leave, tell us when you call so we can plan around it.
Frequently asked questions
Can a lock that won't turn always be repaired?
Often, but not always. When the cause is dirt, a worn key, or a misaligned door, repair is usually straightforward. If the internal parts are broken, badly worn, or damaged by forced entry, replacement may be the more sensible route. We'll tell you which situation we're in once we've inspected the lock.
What should I do if my key is stuck in the lock?
Stop pulling and twisting hard. Try gently wiggling the key while applying very light pressure. If it doesn't release, call us. Forcing it can snap the key or damage the cylinder, and extracting a stuck key cleanly is usually a lighter job than repairing a broken one.
Is a loose door lock a security problem?
It can be. A loose knob, lever, or deadbolt means the mounting hardware is failing, and a lock that isn't firmly attached is easier to defeat. The fix is often simple: re-seating, tightening, or replacing a stripped part. It's worth addressing before it gets worse.
Do you repair mortise locks?
Yes. Mortise locks are common in older homes and some commercial doors, and they're often worth repairing because they're durable. Parts can be harder to find, so repair sometimes involves cleaning, adjusting, or making a part work instead of ordering a new one.
How do I know if I need repair, rekeying, or replacement?
If the lock is malfunctioning, you need repair. If it works fine but you want old keys disabled, you need rekeying. If the lock is damaged beyond reliable repair or you want a different type of hardware, replacement is the right call. Describe the situation by phone and we'll help sort it out.
Can you repair commercial locks as well as residential ones?
Yes. We handle both residential and commercial lock repair, including storefront and office doors. Commercial hardware often carries heavier use, so wear patterns differ. If it's a business door that needs to be secure at closing, mention that when you call.
Can a lock be repaired if someone tried to break in?
Sometimes. If the damage is limited to a bent strike plate, a loosened mounting, or a damaged cylinder, repair is possible. If the lock body or door frame is badly compromised, replacement or frame repair may be needed. We assess the actual damage before recommending anything.
Do you fix car door locks and keys?
Vehicle locks and keys vary widely by make, model, and year, and some involve electronics or are dealer-only. We confirm what a specific vehicle needs by VIN or in person instead of assuming, and we'll be upfront if a particular job has to go to the dealer.
Is there a fee just for looking at the lock?
We don't publish numbers on the web, and costs depend on the situation. Ask when you call (213) 577-1366, and we'll explain how the quote works before any work begins, so nothing is a surprise.
