What a broken key actually is, and why it is usually fixable
A snapped key is almost always a mechanical problem, not a lock failure. The key has a blade with cuts along its edge, and those cuts push a set of small pins inside the cylinder to exactly the right height. When the blade breaks, part of it stays in the keyway, the narrow slot the key slides into. The lock itself is usually fine. It just has a piece of metal sitting where the next key needs to go.
That is why extraction is worth attempting before anything destructive. If the fragment comes out cleanly, the same cylinder, the same keys on your ring, and the same door or ignition keep working. Drilling out a lock or replacing an ignition is the expensive path, and we only go there when the clean path is closed.
This page explains the craft in detail: how the work is done, what changes from one lock to another, where extraction stops being the right answer, and what shapes the cost. If you are standing at a stuck door right now, skip ahead to the steps and call (213) 577-1366. A person answers around the clock.
The situations that lead to this call
Keys rarely break for no reason. Knowing what caused the break tells us a lot about what we will find inside the lock, so we ask.
- Metal fatigue. A key that has been bent slightly and used for years develops a weak point, usually right where the blade meets the head. It finally gives way on an ordinary turn.
- Forcing a sticky lock. A lock that has been getting stiff is telling you something. Leaning on the key to turn it is the classic way to snap it.
- A worn or badly copied key. Copies cut from other copies drift from the original. They fit poorly, bind, and break sooner.
- Cold hands, awkward angles, and rushing. Twisting a key at a bad angle in a hurry puts side load on the blade.
- Padlocks and gate locks. Outdoor hardware collects grit and corrosion, so the key works against resistance every time.
- Car ignitions. A worn ignition cylinder or a heavy keychain pulling on the key can crack it, and the key may break off while still in the ignition or partly turned.
- A previous broken key. Sometimes a small fragment was left behind earlier and a new key finally jams against it.
How we handle it, step by step
The order matters. Most damage from broken keys comes from people rushing the first minute of the job, including us if we were careless. Here is how the work goes.
- We ask questions on the phone. What kind of lock is it, a house deadbolt, a car ignition, a padlock? Is the broken piece sticking out or flush with the face? Do you still have the other half of the key? That half is useful, because it shows us the key's cuts and where it broke.
- We look before we touch. With a light and often magnification, we check how far the fragment sits in the keyway, which way the teeth face, and whether the cylinder is turned partway.
- We stop any further damage. If the lock is half turned, we leave it that way until we know what the fragment is wedged against.
- We choose the lightest tool that works. For a fragment with some length showing, thin extractors with small barbs or hooks grip the cut edge and pull it straight back out. For a fragment set deeper, we use a fine pick or a keyway-fitting tool to move it enough to get a hold.
- We work along the keyway, not against it. Pulling at an angle can scratch the pin chambers or bend a pin. We keep tension straight and gentle.
- We clear the keyway. Once the piece is out, we check the slot for shavings, burrs, and any second fragment, then confirm the lock turns smoothly with a good key.
- We tell you what we found. If the cylinder is scored, worn, or showing the reason the key snapped, you hear it plainly, along with your options.

Call (213) 577-1366What a professional checks that a quick attempt misses
The visible fragment is only part of the story. Before we call a job done, we check a handful of things that a casual attempt tends to skip.
First, the pins. A pry or a bent paperclip can knock a pin out of position or even push a spring out of its chamber. A lock with a disturbed pin may accept a key once and then act oddly later. We make sure the lock works with a clean key, several times, in both directions.
Second, the key you started with. If it snapped because it was a worn copy, using the same copy again puts you right back in the same situation. We compare the remaining half of the key to the lock and tell you if a fresh cut from a better original makes more sense.
Third, the hardware around the lock. A door that sags or a latch that no longer lines up with the strike plate makes every key work harder. If the real reason the key broke was a door that drags, you will want to know, because a new key will just break again.
Fourth, the lock's condition. A cylinder with heavy wear or corrosion can be extracted and still be near the end of its useful life. We tell you honestly whether it is worth keeping.
How hardware, keys, and vehicles change the job
Broken key extraction is not one technique. The lock type decides almost everything about how we approach it.
Standard pin tumbler locks, the kind on most house deadbolts and knob sets, are the most straightforward. The keyway is accessible and the cylinder is easy to work with at the door. Higher-security cylinders with tighter keyways or additional pin types leave less room for tools, so the work is slower and more careful.
Padlocks vary widely. A laminated padlock with a thin keyway gives you little to grab. A hardened shackle lock is hard to attack from the outside, so we focus on the keyway and avoid forcing the body. Padlocks are also relatively inexpensive to replace, and sometimes that is the more practical route. We will say so.
Mortise and commercial cylinders, such as on storefront doors, often have their cylinder removable from the door, which lets us work on the bench if needed. For business situations, see our page on business lockouts, since a broken key and a locked door often arrive together.
Car keys add complexity. Some automotive keys are a plain metal blade, while many have a transponder chip in the head that the car checks before it will start. A broken blade may leave the chip in the head you are holding or not, depending on where it snapped. Whether we can cut and program a replacement depends on the specific make, model, year, and key type, and information on that varies. We confirm by VIN and in person rather than guess over the phone. In some cases, a replacement key for a particular vehicle can only be done through the dealer, and if yours is one, we will tell you straight rather than start a job we cannot finish.
Ignition cylinders have wafers or pins and a turning mechanism with a steering lock. A fragment in an ignition often sits against that mechanism, so we work especially gently. If the car is on a street or in a parking structure, our mobile vans come to the vehicle, which is one more reason this is often handled at the car rather than a shop.

Call (213) 577-1366Honest limits: when extraction is not the right call
Most broken keys can be pulled. Some cannot be pulled safely, and a good tradesperson says so early.
If the fragment is jammed against a damaged pin, or the keyway has been scored by previous attempts with a screwdriver or a blade, extraction may not fully succeed. In those cases we may remove the cylinder, disassemble it, and clear it out on the bench. If the cylinder is badly worn, replacing it or rekeying it is usually the cleaner outcome.
Extraction also does not solve a separate problem that arrives with it. If you are shut out and the key is stuck inside, that is two jobs: getting the fragment out and getting the door open. For a house, that can overlap with house lockout service, and for a vehicle, with car lockout. We can often do both in one visit, but they are different skills, and we will tell you which is which.
Finally, extraction is not a substitute for a replacement key. Once the fragment is out, you still need a working key cut from a sound original. And if a key snapped in a lock because the lock itself is failing, getting the piece out only buys time.
What affects the price, without the guesswork
We do not quote numbers on a web page, because honest pricing depends on facts we can only learn by hearing or seeing the problem. We will give you a clear quote on the phone or at the lock before we start. You can read more about how we approach this on our pricing page. Here is what actually moves the cost.
The lock or vehicle type matters most. A standard house cylinder is a lighter job than a high-security cylinder or a vehicle ignition. How deep the fragment sits and whether it is wedged also shape the effort involved.
Whether the lock needs more than extraction changes things too. If the cylinder needs to be removed, rekeyed, or replaced, those are additional items, and you decide whether to do them. A replacement key, especially a transponder key for a vehicle, is separate from the extraction itself.
Timing and location play a role. A night call or a long drive to a remote location is not the same as a daytime visit nearer the shop. We will explain how that affects the quote.
Where the lock is also counts. A door we can reach easily is simpler than one in a tight spot, and a vehicle in an open lot differs from one in a cramped garage.
What we will not do is quote something low on the phone and add to it once we arrive. If something unexpected shows up inside the lock, we stop, explain, and let you choose.

Call (213) 577-1366Why call Wilshire Lock & Key
We have been in business since 1987, and broken keys are among the oldest problems in this trade. The same few causes keep showing up, and the same patient technique keeps working.
We are one company. When you call (213) 577-1366, you are not reaching a call center that sells your job to whichever subcontractor will take it. The people answering are part of the company that sends the van. That means the person you speak with can tell you who is coming and what to expect.
David, the owner and lead technician, oversees how this work is done. He cares that a lock leaves our hands working properly, not just open.
We have a storefront at 10740 Wilshire Blvd in Westwood, Los Angeles 90024, and mobile service vans. The storefront matters for bench work. When a cylinder has to come out and be cleared with proper light and tools, we do not improvise in a driveway. The vans matter because a broken key is not something you can carry to a shop. The door, the padlock on a gate, or the car is where it is.
One more practical point: California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you call for theirs before work begins. It is a reasonable question and a good company will not mind it.
Where we work: two counties, 140 cities
We serve 140 cities across Los Angeles and Ventura counties. That coverage runs from the Westside, where our storefront is, to the Valley, the San Gabriel side, and into Ventura County. The full list is on our locations page.
If you want to see how we describe the work for a specific area, we keep separate pages for individual cities, including Los Angeles and Pasadena. Those pages cover that place. This page covers the craft, which is the same wherever the lock is.
If you are not sure whether we cover your address, call (213) 577-1366. If you need a technician to come to you, our mobile locksmith service page explains how the vans work. And if the situation has become bigger than a snapped key, say a lockout in the middle of the night, our emergency locksmith service page covers how we handle urgent calls.
What to do right now, and what to avoid
While you wait or before you call, a few things help and a few things hurt.
- Do not try to push the fragment deeper. A push tends to jam it against the pins and makes extraction harder.
- Do not use a screwdriver, a knife, or a drill. These scratch the keyway and can ruin the cylinder.
- Do not use glue to reattach the key. Adhesive in a keyway is one of the worst things that can happen to a lock.
- Do keep the other half of the key. It tells us the original cuts.
- Do note whether the lock is half turned, whether the key broke while turning, and whether the car was on. These details guide our approach.
- Do tell us if the door is closed and locked with you outside, or if you are inside and just cannot unlock it. Those are different problems.
Frequently asked questions
Can a broken key always be removed without damaging the lock?
Not always, but most of the time. The outcome depends on how deep the fragment sits, whether it is wedged against a pin, and whether the keyway was scratched by earlier attempts. If clean extraction cannot be done safely, we explain the next option, such as bench work on the cylinder or replacing it, before we do anything.
Should I try tweezers or a paperclip first?
We would rather you did not. Those can push the fragment deeper, bend a pin, or scratch the keyway. If a piece of the key is sticking out far enough to grip easily, gentle straight pulling is one thing, but anything involving force or levering usually makes the job harder.
My key broke in the ignition. Can you handle that at my car?
Yes, our mobile vans come to the vehicle. We confirm what kind of key and ignition you have by VIN or in person, because that determines how we extract the fragment and whether we can cut and program a replacement. Some vehicles may need the dealer for a replacement key, and we tell you plainly if yours does.
I have both halves of the key. Can you just glue it back together?
No, and please do not try. Glue near a keyway can get into the lock and cause a much bigger problem. A glued key is also weaker than it looks and breaks again. A new key cut from a sound original is the right fix.
Will I need a new lock after the key is extracted?
Often not. If the cylinder turns smoothly with a good key afterwards, there is no reason to replace it. If it is worn, damaged, or the key snapped because the lock was failing, we will explain that and let you decide.
What if the key broke off while I am locked out?
Then you have two problems at once. We remove the fragment and get the door or vehicle open. Depending on the lock, those may be done together, and we will explain how. Our house, apartment, and car lockout pages describe the opening side.
Why do I need to tell you which way the lock was turned?
A cylinder turned partway holds its internal parts in a different position than one at rest. That affects where the fragment is wedged and how we work on it. Telling us up front helps us choose the right tool for the first attempt.
How do I know a locksmith is legitimate?
California requires locksmith companies to hold a BSIS LCO license. Ask for it before work starts, and ask who will actually be coming to you. A real company can answer both questions easily.
Do you charge more for nights and weekends?
The timing and distance of a call can affect what the job costs, and we explain that when you call. We do not quote one thing on the phone and change it at the door. You get a clear quote before we start, and you decide whether to go ahead.
