What is actually wrong with your lock?
Locks rarely fail all at once. A key that needs a little jiggle in spring is often a key that will not turn by midsummer. A deadbolt that takes a shoulder push to throw is telling you something is out of alignment or worn. If you catch the problem early, repair is usually all you need. If you wait until the key snaps or the bolt freezes with you on the wrong side of the door, the same problem gets more urgent and often more involved.
Here are the symptoms we get called about most often on residential doors:
- The key goes in but will not turn, or turns only with force.
- The key is stuck in the lock and will not come back out.
- The deadbolt does not fully extend or retract, or the thumb turn spins without moving the bolt.
- The handle or knob is loose, wobbles, or has started to droop.
- The latch no longer catches, so the door drifts open or has to be lifted or slammed to close.
- The lock works from inside but not from outside, or the other way around.
- The cylinder spins freely in the door instead of holding firm.
How does lock repair work, step by step?
Repair is a diagnosis job first. The most common mistake is treating every sticky lock as a bad lock, when the cause is often the door, the strike plate, or something small inside the cylinder. This is how we approach it.
- You call (213) 577-1366. Someone answers any hour of the day or night, and you describe what the lock is doing. Details like whether the key goes in smoothly, whether the door is open or closed, and whether it happens on both sides help us plan the right tools.
- We come to you in a mobile van, or you can bring a removable lock to our Westwood storefront at 10740 Wilshire Blvd if that suits you better.
- We test the lock with the door open and then closed. Many locks bind only when the door is shut, which points to alignment rather than a failed lock.
- We inspect the key itself, the keyway, the cylinder, the bolt or latch, and the strike plate. A worn key can mimic a worn lock, so we check that first.
- We explain what we found in plain terms and tell you whether repair, a part swap, or replacement is the sensible path. You decide before we go further.
- We carry out the repair. That can mean cleaning and lubricating with the correct product, realigning a strike, replacing worn internal parts, tightening or rebuilding a mounting, or swapping a failed cylinder while keeping the rest of the hardware.
- We test the lock repeatedly, with the door open and closed, and show you how it should feel so you can tell if something changes later.

Call (213) 577-1366Why is my lock not turning, or my key stuck?
These two complaints sound alike but have different causes, and the wrong fix makes either worse. Please do not force a key that is stuck. A key that is bent, worn, or half-broken can snap, and then you also need broken key extraction before the lock can even be repaired.
A lock that will not turn is most often one of these: a worn or poorly cut key, debris in the keyway, pins that have gummed up or worn unevenly, a door that has shifted so the bolt rubs the strike, or a bolt that is catching on something inside the door. A key that is stuck usually comes down to a damaged key, a damaged cylinder, or a plug that has partly rotated and jammed against the pins.
A jammed door lock, where the key works but the bolt will not move, usually means the problem is in the mechanism or the alignment, not the cylinder. Lubricant sprayed in by hand is tempting, but the wrong product attracts dust and grit and turns into paste. We use lubricants made for locks and only where they help.
If the door is locked and you cannot get in, that is a different situation, and our house lockout service covers it. Once you are inside, we can look at the lock itself.
What about deadbolt, mortise and latch repair?
Not all locks fail the same way, and the repair depends on what is in the door.
Deadbolt repair is the most common. Problems tend to be a bolt that does not line up with the strike, a thumb turn that has lost its connection to the bolt, or a cylinder that has worn. Many of these are fixable without replacing the whole deadbolt. If the bolt is simply too short or the hardware is too worn to rely on, we will tell you, and you can look at lock replacement as the next step.
Mortise lock repair is a more specialized job. A mortise lock sits inside a pocket cut into the edge of the door and is common on older homes. Parts can be hard to find, and the repair often means working with the original body, springs and levers rather than swapping a modern equivalent. These locks are worth saving when they can be, since the hardware is often better made than many current retail sets.
Latch repair covers the spring latch in a knob or lever set, the part that holds the door shut. A latch that sticks, does not retract, or no longer catches can be a worn spring, a bent latch, a misaligned strike, or a door that has moved slightly in its frame. Often we adjust the strike or replace the latch assembly and leave the rest alone.
Loose door lock repair is usually about the mounting. Through-bolts that have worked loose, a cracked cylinder collar, or stripped wood around screw holes all let a lock wobble. We reinforce or rebuild the mount where we can.

Call (213) 577-1366Should you repair the lock or replace it?
We lean toward repair when it is sound, because it usually keeps the hardware you already like and is often the more economical route. But we do not repair things that should not be repaired, and we will say so.
- Repair makes sense when the lock is a decent grade, the damage is limited to a worn part or an alignment issue, and the door and frame are in good shape.
- Replacement makes sense when the lock is badly corroded, the body is cracked, parts are no longer available, or the hardware was never strong enough to protect the door in the first place.
- Rekeying is a separate question. If the lock works fine but you are worried about who has keys, that is a lock rekey job, not a repair job.
- If a lock has been forced or tampered with, we look at the door and frame too, because a repaired lock in a damaged door is not secure.
How much does lock repair cost in Altadena?
We do not quote numbers on a web page because the honest answer depends on what is wrong. A short list of what moves the cost up or down:
The kind of lock matters. A common deadbolt is simpler to work on than a mortise lock or a high-security cylinder. The cause of the problem matters: a strike adjustment is a different job than rebuilding a mechanism. Parts matter, since some are on hand and some need to be sourced, especially on older hardware. The condition of the door and frame matters, because a swollen or shifted door can be the real problem. Timing and travel matter too. A late-night call is not the same as a scheduled visit, and we are based in Westwood, so the distance to Altadena is a factor.
What we do commit to is telling you the cost before work starts, once we have seen the lock. If we find that repair would cost close to a replacement, we will say so, so you can make a sensible choice.
What makes lock repair different in Altadena?
Altadena sits in the foothills, and that shows up in locks. Summers run hotter than in the basin, and dry Santa Ana winds off the San Gabriels carry grit. Sun and wind-blown dust are the main wear factors on exterior doors, so front-door deadbolts and screen-door latches here often go gritty or stiff before the mechanism itself is truly worn. Cleaning and proper lubrication fix a surprising share of those calls.
The housing stock is also unusual right now. After the January 2025 Eaton Fire, many blocks, especially in West Altadena, are rebuilding, while other streets still have surviving older homes. That puts new-construction door hardware right next to original early-1900s locksets. On a surviving Craftsman bungalow near the Christmas Tree Lane district off Santa Rosa Avenue, or a Janes Village cottage, we are often repairing vintage hardware, including mortise lock repair, rather than replacing it. If you want to keep the original character, repair is often the right call. If the house has also had keys floating around, pair the repair with a lock rekey.
On rebuilt homes in The Meadows, East Altadena or anywhere in ZIP code 91001, the issue is usually different. New doors in new framing can shift as the house settles, so latches stop lining up with strikes. That is a repair job, not a faulty lock.
In La Viña, the gated hillside community at the northwest edge, gates and entry hardware get the same sun and wind exposure. For those, our gate lock repair page covers what we do.
We are based at 10740 Wilshire Blvd in Westwood, roughly 26 miles from Altadena, and our mobile vans come to you.

Call (213) 577-1366Do you also handle commercial lock repair?
Yes. Commercial lock repair follows the same diagnosis-first method, with different hardware: heavier cylinders, door closers, panic hardware, and storefront doors that get used all day. We will not go deep here, since storefront lock repair has its own page, but if a business door sticks, does not latch, or will not lock at closing time, call the same number. With reconstruction ongoing in Altadena, a lot of properties are mixing temporary and permanent hardware, and we can help sort out which locks are worth repairing.
Why call Wilshire Lock & Key?
We have been in business since 1987 and serve 140 cities across Los Angeles and Ventura counties. When you call, you reach the company that does the work. There is no dispatch middleman passing your job to whoever is available, and David, the owner and lead technician, oversees the work. We have a physical storefront as well as mobile vans, so there is an actual address behind the phone number.
Phones are answered 24 hours a day, 7 days a week, year-round, so if a lock fails late at night we can start the conversation then. If it turns into a lockout or a security problem, our emergency locksmith service page explains how that works, and our mobile locksmith service page covers how our vans work.
One thing worth knowing about any locksmith: California requires locksmith companies to hold a BSIS LCO license, issued by the Bureau of Security and Investigative Services. Ask any locksmith for that license number before they start work, and expect a direct answer.
Frequently asked questions
Can you repair my lock instead of replacing it?
Often, yes. If the lock is a sound grade and the problem is a worn part, a dirty mechanism, a loose mount, or an alignment issue, repair is usually the more economical route. If the body is cracked, badly corroded, or parts are unavailable, we will say replacement makes more sense.
My key is stuck in the lock. What should I do?
Stop pulling and twisting, since force can snap the key and turn a repair into something bigger. Do not spray random lubricant into the keyway. Call (213) 577-1366 and describe what happened. If the key has already broken, we can handle the extraction and then repair the lock.
Why does my deadbolt work sometimes and not others?
Intermittent trouble usually means alignment. Heat, humidity and settling can shift a door slightly so the bolt rubs the strike plate, and Altadena's hot summers can make this worse. It can also be a worn cylinder or a tired key. We test with the door open and closed to tell which.
Is a loose door handle a security problem?
It can be. A loose lock is easier to force and will keep working itself looser. Often the fix is tightening or rebuilding the mount, not buying new hardware. If wood around the mounting is damaged, we reinforce it so the lock holds firm again.
Can you repair old Craftsman-era locks?
Often, yes. Older mortise locksets and early hardware were well made, and parts like springs, levers and cylinders can frequently be repaired or rebuilt. Some parts are hard to find, and we will tell you honestly what is feasible. If the hardware cannot be saved, we can talk through alternatives.
Will you come out at night for a lock that will not turn?
Our phone is answered 24 hours a day, 7 days a week, year-round. If your lock is failing at night, call (213) 577-1366 and we will talk through whether it can wait or needs attention right away, especially if the door will not lock or you cannot get in.
Do you repair gate and commercial locks too?
Yes. We handle residential and commercial lock repair. For gates, see our gate lock repair page, and for business doors, our storefront and commercial pages. The approach is the same: diagnose first, then repair or replace, with the cost explained beforehand.
What should I check before calling about a sticking lock?
Try the key in the lock with the door open. If it works smoothly open but sticks when closed, the door or strike plate is likely the issue. Also check whether a spare key behaves the same way. If the spare works better, your main key is probably worn. Tell us what you find when you call.
