What should you do first when a key breaks in the lock?
A key that snaps inside a lock feels like an emergency even when nothing else is wrong, because the door or the car is now shut and you are on the wrong side of it. Most broken keys can be removed cleanly, as long as the piece left behind is not pushed deeper or wedged tighter before someone with the right tools gets to it.
The first few moments matter more than people expect. Here is what helps, and then what to leave alone.
- Stop turning. Do not push the lock in either direction. The blade that remains is weaker than it looks, and the pins inside are already gripping it.
- Look at the keyway. Note whether a bit of the blade sticks out of the lock face or whether it broke off flush or deeper inside.
- Keep the part of the key you are holding. The head and the broken section can help us match the cuts, and we will want to see both.
- Think about whether there is a legitimate second way in, such as another door you have a key to or a household member who can let you in. If there is, the repair can wait for a calmer moment.
- Call (213) 577-1366. We answer around the clock, and describing what you see usually tells us what tools to bring.
What not to do with a key broken inside a lock
Many service calls start the same way: someone tried to fix it first. We do not say that to scold anyone, because the urge is natural. But a few common attempts turn a simple removal into a larger repair.
- Do not use superglue to rejoin the pieces. Glue in a keyway can seize the cylinder, and then it usually has to be replaced rather than saved.
- Do not push the broken piece in with a nail, screwdriver, or another key. That packs it against the pins and makes it harder to reach.
- Do not spray heavy oil or grease into the lock. It collects dust and grit and can leave the cylinder gummy long after the key is out.
- Do not pull at a protruding piece with pliers if only a sliver shows. Pliers often snap off the last of the blade flush with the face.
- Do not keep turning a binding lock hoping it will give. A second snap leaves less to grab.
Why do keys snap, and what makes it worse?
A key rarely breaks for no reason. Usually metal fatigue has been building for months or years. Brass keys flex a little each time they turn, and a copy cut from another copy may be slightly off to begin with. Eventually a key with a worn shoulder or a hairline crack gives way under ordinary pressure.
The lock matters as much as the key. A bolt that drags, a door that has shifted so the latch binds in its strike, or a cylinder dry of any lubrication all make the key work harder with every turn. When the lock resists, people twist harder, and the weakest point in the system is the key. That is why a key that snaps is often a sign that the lock or the door needs a look after the extraction, not only a new key.
The break itself comes in a few forms. Some keys snap flush with the face, leaving nothing to grip. Some break partway, leaving a stub. Others break deep, with the blade sitting among the pins. Each of these calls for a slightly different approach, which is why we ask what you can see when you call.

Call (213) 577-1366How does broken key extraction work, step by step?
Extraction is patient, hands-on work. The goal is to get the broken piece out and leave the lock working, so the cylinder survives instead of being drilled out. Here is how a typical visit goes.
- We look at the lock first: what kind it is, how the key broke, and how far the piece sits inside. A deadbolt, a knob lock, a mailbox lock, and a car door lock each behave differently.
- We check whether the cylinder is still turning freely. If it is partly rotated, we note the position, since that decides how the piece can be reached.
- We select the extraction tool. A thin extractor with a small hook or barb can catch a piece that sits flush. Fine tweezers or small pliers work if enough is exposed. Some cases need a narrow pick used to ease the pins back and free the blade.
- We work the piece out along the line of the keyway, not sideways, so the pins and the keyway walls are not scored.
- We confirm the cylinder is clean and operating by turning it with a fresh key or by picking it ourselves. If the pins or springs were damaged, we tell you before touching anything else.
- We then explain what we found, show you the removed piece, and talk through your options for a replacement key or any needed lock work.
Can a broken car key or ignition key be extracted?
Yes, in many cases. A broken car key stuck in a door lock or ignition cylinder is extracted by the same principles as a house key, but car locks have their own wrinkles. Automotive keyways are often narrow and wafer-based, and an ignition cylinder is tied to the steering column, so the angle of access is tighter. We take extra care because an ignition that is forced can turn a simple extraction into an ignition repair job.
Newer keys complicate things in another way. Many vehicles use a key with an electronic chip, and whether the chip lives in the head or elsewhere varies by make and model. Because that detail is not the same across vehicles, we do not guess. We confirm by VIN and by looking at the key in person, and we tell you plainly whether the remaining head can still be used or whether you will need a car key replacement. Some vehicles may also require dealer-only steps for particular key types, and if yours is one of them, we will say so rather than let you wait on something we cannot do.
- Door lock breaks: usually a wafer lock, often extractable on site.
- Ignition breaks: need care to avoid damaging the cylinder or the column.
- Trunk and glove box locks: simpler, but the same no-force rule applies.
- Key and chip questions: confirmed by VIN and in person, never assumed.

Call (213) 577-1366What affects the cost of broken key removal?
We do not quote numbers on a web page because the work varies too much, but we can tell you exactly what moves the cost, so you are not surprised.
The biggest factor is how the key broke. A piece that sticks out of the lock and comes free in one pull is quick work. A piece that snapped flush, or sits deep behind a tight set of pins, takes more time and finer tools. Next is the type of lock: a standard house cylinder, a high-security cylinder with restricted keyways, a car ignition, and a mailbox lock each call for different approaches.
Whether we come to you matters too. A mobile call to a home, a parking lot, or a building is a different job from bringing a lock or a key to our storefront. The time of day plays a part, since a call in the middle of the night involves different effort than a daytime appointment.
Then there is what happens after the key is out. If the cylinder is undamaged, the extraction may be all you need. If it is worn or damaged, you may want lock repair or a new cylinder. If you need a new key, there is the cost of cutting it, and for a vehicle, possibly programming. We lay out those steps before we start each one, so the extraction is never a hidden path to a larger bill. Asking for the lighter-cost option is always fair, and in many cases a clean extraction with a new key cut is usually the more economical route.
Why call Wilshire Lock & Key for a snapped key?
We have been in business since 1987, and a broken key is one of the oldest calls in the trade. The tools have improved, but the judgment about when to use which one comes from years at the lock.
We are one company, not a call center passing your address to whoever is closest. We run a storefront at 10740 Wilshire Blvd in Westwood and a fleet of mobile service vans, so the person who answers the phone works for the same business that sends the technician. David, the owner and lead technician, oversees the work. Lake Balboa is about 13 miles from our base, and we serve 140 cities across Los Angeles and Ventura counties.
One more point, which applies to any locksmith, not only us. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith you call for it before work begins. It is a fair question and a reasonable way to tell a real company from a lead-generation listing.

Call (213) 577-1366Broken key extraction in Lake Balboa: homes, apartments, and parking lots
Lake Balboa, ZIP 91406, was carved out of Van Nuys as its own neighborhood in the early 2000s, and much of the housing is classic postwar Valley stock: single-story stucco homes from the 1940s and 1950s on modest lots. In homes off the Balboa Boulevard corridor that have not been updated, the original hardware is still common. Older locks that have been turned thousands of times are exactly where keys wear and snap, and we often see a cylinder worn enough that a fresh key feels loose in it.
The climate adds to it. The neighborhood sits on the Valley floor beside the Sepulveda Basin, with hot, dry summers and somewhat damper air near the basin's irrigated parkland and lake. That seasonal swing produces the usual modest sticking and alignment issues in older wood doors. A door that binds a little in the latch makes the key work harder, and that is a common backdrop to a snapped key.
Apartment buildings run along the Sherman Way and Victory Boulevard corridors, and a key that breaks in a unit door there often comes with a lockout attached. If that is your situation, see our page on apartment lockouts. Older multifamily buildings also have small locks that get less attention, like security screen doors and mailboxes, and a small key in a mailbox lock snaps more easily than a house key.
We also get calls from the Vanowen Street corridor and the area around Birmingham Charter High School, plus the edge of the Sepulveda Basin near Anthony C. Beilenson Park, where a key that breaks in a car door in the parking lot is a stressful way to end a park visit. We come to wherever you are parked.
What happens after the key is out?
Getting the broken piece out is only half the story. The other half is making sure it does not happen again. Once the lock is clear, we test it and look at the key you were using, and then the conversation turns to what the lock needs.
If the broken key was a copy of a copy, the likely culprit is the cut. We can cut a clean new key from the original, or from the broken pieces if they are intact enough to read. See our key duplication page for how that works.
If the cylinder is worn, damaged, or part of a lock that is simply past its working life, we will say so and explain what a lock replacement would involve. Often the lock is fine and only the key was tired. We would rather tell you that than sell you hardware you do not need.
If the door itself is binding, we will point it out, since a lock fighting the door will break another key sooner or later.
- Lock clean and smooth: new key cut, and you are done.
- Lock worn: repair or replace the cylinder, your choice after we explain.
- Door binding: adjustment recommended so the key is not the weak link.
- Vehicle key: confirmed by VIN and in person before any decision.
Frequently asked questions
Can you remove a key that broke flush with the lock?
Usually, yes. A key that snapped flush leaves nothing to grip, so we use a thin extractor or a pick to catch the blade along the keyway. It takes more time and finer tools than a protruding piece, but it is routine work for us, and the cylinder generally survives.
Will extracting the key damage my lock?
Done properly, no. The aim is to free the piece along the keyway without scoring the pins or walls. Damage usually comes from earlier attempts, like glue or prying. If we find existing damage, we tell you before doing anything else.
Is it ever necessary to drill the lock?
Rarely. Drilling is a last resort when the piece cannot be reached or the cylinder is already seized, for example by glue. We try extraction first, and if drilling is the only way, we explain why and what replacement hardware you will need.
My car key broke in the ignition. Can you get it out?
In many cases, yes. Ignition cylinders are tight and tied to the column, so we work carefully. Whether the remaining key head or its electronic chip can be reused depends on the vehicle. We confirm by VIN and in person, and we will say plainly if a dealer-only step is involved.
What if only the broken half is in the lock and I still have the head?
Keep the head. It lets us compare the cuts and often makes a replacement key straightforward. Please do not try to glue the pieces together or push the broken half in further, since that makes extraction harder.
Do you come to me, or do I have to bring the lock in?
We come to you. Our mobile vans serve Lake Balboa and the rest of our 140-city area, and we handle most extractions on site, whether it is a front door, an apartment unit, or a car in a parking lot. You can also visit our Westwood storefront at 10740 Wilshire Blvd.
Can a broken key in an old postwar lock be removed without replacing the lock?
Often, yes. Older hardware in Lake Balboa homes is sturdy, and a worn cylinder can still work after a clean extraction. We check the pins and springs once the piece is out, then tell you whether the lock is fine or due for an update.
Are you available at night and on weekends?
Yes. Our line at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round, including holidays. A key that snaps late at night is no less urgent, and we handle those calls the same way as daytime ones.
