What is broken key extraction, and when do you need it?
Broken key extraction is the work of removing the part of a key that snapped off inside a lock, along with any fragment still lodged in the keyway, without harming the cylinder and pins the key was made to turn. It applies to front-door deadbolts, knob sets, mortise locks, padlocks on side gates, mailbox locks, and car door and ignition cylinders. People search for it as broken key removal, a key broken inside a lock, or a broken key stuck in a door. It all comes down to the same problem: a piece of metal is where it should not be, and the lock is blocked until it comes out.
Sometimes the broken half is still sticking out and you can grip it. Other times it is flush with the face of the lock or sitting deeper inside, and all you can see is a dark slot with a glint of brass. Either way, the smartest first move is to stop using the lock and call. One more hard twist, or a push with a screwdriver, is how a simple extraction turns into a drilled lock and a replacement cylinder.
Why do keys snap inside locks?
Keys rarely break for no reason. Almost every snapped key we see traces back to one of a handful of causes, and knowing which one applies helps decide what happens to the lock afterward.
A key that bent slightly or has a hairline crack near the shoulder is giving you a warning. If you notice that, get a fresh key made from a sound original before it fails at a bad moment.
- Metal fatigue: a key used daily for years flexes a tiny amount each time, and the brass eventually gives way near the shoulder or the thinnest part of the blade.
- A worn or poorly cut copy: a duplicate made from another duplicate drifts from the original cuts and is often softer metal, so it binds and snaps.
- A dirty, dry or misaligned lock: when the cylinder is gummed up or the door and strike no longer line up, people force the key and the weakest point breaks.
- A door that binds: if you lean on the door while turning the key, the bolt is under load and the key takes the strain.
- Cold, stiff or corroded mechanisms: old hardware that has gone years without service resists turning and tempts people to use more force.
How do we remove a broken key without damaging the lock?
The method depends on how much of the key is visible, what kind of lock it is, and what shape the lock is in. Here is how a typical call goes.
- We talk it through on the phone: which lock, how much of the key you can see, whether the door is open or closed, and whether anyone is locked in or out.
- On arrival we inspect the keyway with a light and magnification to see how the fragment sits, how many cuts remain, and whether anyone has already tried to dig it out.
- If part of the key protrudes, we grip it with fine-nosed extractor pliers and draw it straight out along the keyway, never twisting against the pins.
- If it sits flush or recessed, we use thin extractor tools made for this work. These are slim hooked or serrated blades that catch a cut on the key and pull it out along the same path it went in.
- We keep the pins and springs undisturbed and use a small amount of lock-appropriate lubricant where it helps the fragment slide.
- Once it is out, we test the lock with a good key, check that the plug turns freely, and make sure the bolt or latch moves fully.
- If we find damage to the cylinder or pins, we tell you what we see and what the options are before doing anything beyond the extraction.

Occasionally a piece is wedged behind a pin, bent inside the plug, or the lock was already damaged by earlier attempts. In that case we may remove the cylinder from the door and work on it at the bench, where we can take it apart safely. Drilling is the last resort, not the first, and if it comes to that we say so before we start. If the cylinder cannot be saved, we replace or rekey it, and you leave with a lock that works. If the lock itself is worn out, our lock repair work covers what comes next.
What about a key broken in a car door or ignition?
Broken car key extraction follows the same principle, but vehicles add complications. An ignition cylinder is tied to the steering column and, on many vehicles, to an anti-theft system. Many modern keys also carry a transponder chip in the head, and whether a replacement key needs programming depends on the specific vehicle. We do not guess at that. We confirm the details by VIN and in person, and if your vehicle turns out to be a case where the dealer has to be involved for a particular key or immobilizer step, we tell you plainly rather than send you in circles.
Keep both pieces if you can. The head of the key is the part that may hold the chip, so do not throw it out, even if the blade is the part stuck in the lock. If the key broke in the ignition, see our ignition repair page for what happens if the cylinder itself is worn. If you need a new key made and programmed afterward, that is covered under transponder key programming.
If the key snapped in a door lock and the car is now locked with the keys inside, you have two problems at once. Our car lockout service deals with the entry side, and we can handle both in a single visit.
What affects the cost of broken key extraction?
We do not quote numbers on a web page because the job varies too much to do so honestly. What we can do is tell you what moves the cost up or down, so there are no surprises when we give you a figure on the phone or at the door.
In general, pulling out a fragment and leaving the original lock in place is usually the more economical route compared with replacing the hardware. The lock survives, your existing keys keep working, and you avoid buying new cylinders. Where a lock has to come apart or be replaced, the work grows. We explain what we see and what each option involves before we do anything beyond the extraction.
- Type of lock: a standard deadbolt is simpler than a mortise cylinder, a high-security cylinder, a padlock, or a vehicle ignition.
- How much of the key remains and where it sits: a protruding piece is quick work, while a fragment lodged deep behind the pins takes more care.
- Condition of the lock: corrosion, grime, or earlier attempts to dig the key out all add difficulty.
- Whether the cylinder has to be removed: taking a lock off the door for bench work adds time.
- Whether a new key is needed: cutting a replacement is separate from the extraction, and a transponder key adds programming.
- The vehicle, if it is a car key: make, model, and key type decide what is possible on site.
- Time of day and location: after-hours calls and more distant addresses can affect the total, and we tell you how when you call.

Call (213) 577-1366Why call Wilshire Lock & Key for a broken key?
We have been in business since 1987, and snapped keys are among the oldest problems in this trade. We run a storefront at 10740 Wilshire Blvd in Westwood, along with mobile service vans, so there is a real shop behind the van that shows up. You deal with one company, not a call center that passes your job to whichever subcontractor is free. David, the owner and lead technician, oversees the work. Our phone is answered 24 hours a day, 7 days a week, year-round at (213) 577-1366, and for after-hours trouble you can read more about our emergency locksmith service.
California requires locksmith companies to hold a license from the Bureau of Security and Investigative Services, known as a BSIS LCO license. Ask any locksmith for their license number before they begin work on your lock. It is a fair question, and a legitimate company will answer it.
How does a broken key play out in View Park–Windsor Hills?
View Park–Windsor Hills is an unincorporated Los Angeles County community of hillside streets, with ZIP codes 90043 and 90008 covering much of it. The housing is mostly single-family, owner-occupied homes from the 1920s through the 1940s, Spanish Colonial Revival, Mediterranean and traditional styles, and the View Park historic district was listed on the National Register of Historic Places in 2016. We serve it from our Westwood storefront, roughly 11 miles away.
That housing stock shapes what a broken key looks like here. Many homes in View Park and Windsor Hills still have their original mortise locks, glass knobs and period hardware, and owners often want to keep that hardware rather than swap it for modern sets. A key snapped in a decades-old mortise lock is exactly the case where careful extraction matters most, because the point is to save the lock. Old brass keys and old lock bodies wear together, and a key that has turned the same lock for generations can fail without warning. Our approach is to work the fragment out gently, check the lock, and talk to you about repair before anyone suggests replacement.
Other local situations come up as well. Hillside lots in this area often have terraced yards, gates and side entrances, and a key that snaps in a gate lock leaves you with a locked yard and a bent key blade in the latch. If that gate lock is worn beyond saving, our gate lock repair service is the next step. Homes changing hands, whether through a sale or an inheritance in the historic district, sometimes turn up old keys that have not been used in years, and those keys are the ones most likely to snap on first use. If you are about to move in and the original key breaks, we can pull the fragment and then rekey the locks so that every old key becomes useless.
Climate plays a small part. The hilltop gets marine-layer mornings and breezes, and conditions are mild, with only modest seasonal swelling in older wood doors. Even slight swelling can make an old door bind against its strike, and that is when people lean and twist. For cars, broken keys and lockouts happen along Angeles Vista Boulevard and the Slauson corridor, and we come to you wherever the vehicle is, whether you are near Baldwin Hills, Baldwin Vista, Hyde Park, or the Crenshaw District.

Call (213) 577-1366What should you do before we arrive?
A few simple steps protect the lock and speed the repair. Mostly it is about what not to do.
- Stop turning the key. Do not try to force the lock open or push the fragment deeper.
- Do not use glue, super glue or adhesive to reattach the pieces. Glue in a keyway is far harder to deal with than a broken key.
- Do not poke at it with a screwdriver, a nail, or a knife. These push the fragment further in and scratch the pins.
- Keep every piece of the key, including the head and any loose fragment, and put them somewhere safe. The pieces help us match the cuts and confirm the key type.
- Note whether you can see the broken end and which lock it is, such as the front door, the side gate, or the car ignition. It saves time on the phone.
- If you are locked out as well, tell us when you call so we bring the right tools in the first trip.
What happens after the key is out?
Once the fragment is removed and the lock turns smoothly, you have a choice. If the lock is sound, you can keep it and have a new key made. A fresh key cut from a good original is better than a copy of a worn one, and our key duplication page explains how to avoid copies that wear down quickly.
If the lock shows wear, now is the time to deal with it, since a lock that made one key snap can make another. Options range from cleaning and lubrication to rekeying to a full replacement. We tell you which makes sense for the lock in front of us, and we do not push replacement when the original hardware can be repaired.
Frequently asked questions
Can you remove a key that broke flush inside the lock?
Usually, yes. A fragment that is flush or slightly recessed is still reachable with thin extractor tools that catch one of the cuts and draw the piece out along the keyway. How deep it sits and what shape the lock is in affect how long it takes, and in a few cases we need to take the cylinder out of the door to finish the job safely.
Will my lock still work after the key is extracted?
In most cases it does. Extraction done carefully does not disturb the pins, so the lock works as before. We test it with a good key before we leave. If we find damage, we tell you what we see and what the options are rather than assume you want it replaced.
Can I pull the broken key out myself with pliers or tweezers?
If a good length of the key sticks out, gentle straight pulling with fine-nosed pliers sometimes works. If it is flush or the pliers slip, stop. Pushing, prying, or twisting tends to drive the fragment deeper or damage the pins, and that makes the professional job harder. Never use glue.
Do I need a new lock after a key breaks?
Not necessarily. Many locks come through extraction undamaged. A lock is worth replacing if the cylinder is worn, the pins are damaged, or the mechanism is binding. That is especially relevant for older hardware, where we would rather repair than replace. We will tell you which applies.
My key broke in an old mortise lock. Can that be fixed without replacing the lock?
Often, yes. Many View Park–Windsor Hills homes have original mortise locks that owners want to keep, and extraction is done with the goal of saving that hardware. If the fragment or the lock body makes that impossible, we explain why before suggesting anything else.
Can you come out at night to a hillside home or a side gate?
Yes. We answer the phone 24 hours a day, 7 days a week, and we have mobile vans that come to your door, including homes on hillside streets and terraced lots. Call (213) 577-1366 and tell us which lock is involved and how much of the key you can see.
My car key snapped in the ignition. Can it be removed and replaced on site?
Often the fragment can be extracted at the vehicle. Whether a replacement key can be cut and programmed on the spot depends on the vehicle and the key type, so we confirm by VIN and in person. If your vehicle requires dealer involvement for a step, we say so openly.
Should I keep the broken pieces of the key?
Yes. Keep the head and any fragments. They help confirm the key type and match the cuts, and on a car key the head may contain a chip. Put them in a safe place and have them ready when we arrive.
How much does broken key extraction cost?
It depends on the type of lock, how deep the fragment sits, the condition of the lock, whether the cylinder has to come out, and whether you need a new key afterward. Time of day and location also matter. We explain these factors on the phone and give you the details before we start work beyond the extraction. You can also reach us through our contact page.
