What happens when a key breaks off in a lock?
Keys snap for ordinary reasons. Brass fatigues after years of turning. A worn copy of a copy has a weak shoulder. A lock gets a little stiff and someone leans on the key harder than it was cut to take. Where the key breaks matters a great deal. Sometimes a piece still sticks out of the keyway and can be gripped. Other times the break is flush with the face of the lock or deeper inside, and the fragment sits among the pins where you can't see it.
If you are standing at a door with half a key in your hand, the instinct is to try something. Most of those instincts make the job harder. Here is what to avoid, and what actually helps.
- Do not push the remaining half of the key back in and try to turn it. That can jam the fragment deeper and bend pins.
- Do not use superglue to stick the pieces back together. Glue that reaches the keyway can ruin a cylinder that would otherwise have been fine.
- Do not pry at the fragment with a knife tip or a screwdriver. You are far more likely to scratch the keyway or snap off the last bit you could have gripped.
- Do not spray heavy oil into the lock. Light lubricant is fine for a stiff lock in general, but a lot of oil makes a fragment slippery and harder to grab.
- Do keep every piece of the broken key, including the part still in your hand. It tells us what kind of key and cut we are dealing with.
- Do stop using the lock, and call us at (213) 577-1366 so we can ask a few questions about what you're looking at.
How do we remove a key broken inside a lock?
The method depends on the lock and on how much of the key is left. The goal is always the same: get the fragment out in one straight pull, with the pins and the keyway intact. Our technicians do this work at your door, in the driveway, or at the car, because we run mobile service vans alongside our Westwood storefront. If you want to know more about how that works, our mobile locksmith service in Beverly Hills page explains it.
- We start with questions. Which lock is it: a deadbolt, knob lock, mortise lock, padlock, mailbox, gate, or a car door or ignition? How much of the key is still visible? Do you still have the other half?
- We look into the keyway with a bright light and magnification to see where the fragment sits and which way the teeth face. That tells us how it is lodged before anything goes in.
- We choose the least invasive method. If a piece sticks out, a fine gripping tool may be all it takes. If the break is flush, we slide thin extractor tools with small hooks alongside the blade and catch the cuts of the key itself.
- We draw the fragment straight out rather than twisting it. Twisting is how pins get bent and how a cylinder gets scored.
- We clear any brass shavings from the keyway and test the lock with a key that works, checking for stiffness, bent pins, or debris that could make the same thing happen again.
- We tell you plainly what we found. If the lock is fine, we say so. If something inside is worn or damaged, we explain the options before doing anything further.

Call (213) 577-1366Is every broken key a clean pull?
No, and anyone who says otherwise is selling you something. Most extractions go well when the fragment is accessible and the cylinder is in decent shape. But a fragment that is wedged deep, a lock that has been jammed already by someone's attempts at a fix, or an older cylinder full of grit can mean the cylinder has to come out of the door so we can work on it on the bench. That is still usually the more economical route compared with replacing hardware. If a cylinder cannot be saved, we will say so and show you why.
What if a car key broke in the ignition or the door lock?
Car keys add a layer. Many modern keys have a plastic head holding electronics, with a metal blade that can snap off at the head. Whether your particular key has a transponder chip, where that chip sits, and whether a broken head can be reused all depend on the make, model, and year. We do not guess at that over the phone. We confirm by VIN and in person.
When the blade breaks off in the ignition, we extract the fragment from the ignition cylinder the same careful way we would with a door lock. A worn ignition is sometimes the reason the key snapped in the first place. If we find the cylinder is damaged or sticking, we will tell you, and our ignition repair service covers the next step.
Getting the piece out is only half of a car situation. You may also need a working key. If that key needs to be cut and its chip programmed, our transponder key programming page explains what is involved. Some vehicles are dealer-only for certain key types or immobilizer procedures. If yours is one of them, we will say so honestly at the start rather than let you wait on a job we cannot finish.
How much does broken key extraction cost in Beverly Hills?
There is no single figure that fits every snapped key, and a number quoted without seeing the lock is a guess. What we can do is explain what moves the cost, and we explain it before we start work.
Extraction is often the lighter-cost fix compared with replacing a lock, because you keep the hardware you already own. The factors below decide where a particular job lands.
- The type of lock. A standard residential deadbolt is a different job from a mortise cylinder, a high-security cylinder, a padlock, or an ignition.
- How the key broke. A fragment sticking out of the keyway is simpler than one sitting flush or deep among the pins.
- The condition of the cylinder. Grit, wear, previous prying, or a jammed lock all add time.
- Whether the cylinder has to be removed from the door to reach the fragment.
- Whether you also need a new key cut, a key made from a code, or a car key programmed afterward.
- The hour and the distance. Service outside normal hours and the travel to your address are part of the picture, and we're open around the clock either way.
- Whether the lock needs repair, rekeying, or replacement once the key is out. We treat that as a separate decision, and you make it.

Call (213) 577-1366Why 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 a locksmith gets. Experience matters here because the job is mostly feel: knowing how a fragment is sitting by how a tool behaves in the keyway.
You are dealing with one company, not a call center passing your job to whoever is closest. We have a storefront at 10740 Wilshire Blvd in Westwood and mobile vans, and the people who answer the phone at (213) 577-1366 work for the same shop that sends the technician. The phone is answered 24 hours a day, 7 days a week, all year. David, the owner and lead technician, oversees the work. Beverly Hills is about 4 miles from our base, which makes it a short, familiar drive for us.
We also keep the advice honest. If your lock needs only a clean extraction, that is all we will do. If it needs more, we will explain why.
Where do broken keys show up around Beverly Hills?
Beverly Hills is not one kind of housing, and a snapped key behaves differently depending on the hardware it breaks in. North of Santa Monica Boulevard the stock is dominated by large estates from the 1920s onward, many in Spanish Colonial Revival and Mediterranean styles. Mortise locks are common in those older houses, and a key that snaps in a mortise lock in The Flats calls for patience. The lock body is part of the door, and original hardware is not always easy to match. We work to pull the fragment and keep the lock, and if the mechanism itself has worn, our lock repair page covers what comes next.
Trousdale Estates is a different case. It is a distinct 1950s and 1960s mid-century enclave, and estate properties across the city commonly pair high-security deadbolts and mortise hardware with driveway gates, intercoms, and monitored access. A key that breaks in a gate lock or the hardware beside an intercom can leave a household unable to get in or out by its usual route. When the problem goes beyond the broken key to the gate itself, our gate lock repair service is the place to look.
South of Wilshire, the city shifts to duplexes, condominiums, and apartment buildings from the 1930s through the 1970s. Keys in those buildings get a lot of daily use, and a worn key in a front door is a common way for one to snap. If the break leaves you standing outside with nothing to open the door, we handle that too, and our house lockout page covers it.
We cover all three Beverly Hills ZIP codes: 90210, 90211, and 90212. That includes the Golden Triangle business district and the boutique storefronts along Rodeo Drive, where a key that snaps in the door at closing time is a real problem because the shop cannot be left unsecured. It also includes the northern hillside near Coldwater Canyon.
Climate plays a small role here. Beverly Hills has warm, dry summers, and hillside and canyon sections get strong sun that fades and dries exterior door finishes. The effect on hardware is modest. In our experience a snapped key is far more often a story of wear and a worn copy than of weather.

Call (213) 577-1366What happens after the key is out?
Once the fragment is out, you have three questions, and none of them has to be answered in a hurry.
First, does the lock still work smoothly? If it does, you may not need anything else. If it is stiff, worn, or gritty, repair may be the right call. Second, who else has a copy of the key that just broke? If the broken key was an old one that has passed through several hands, such as a former housekeeper, a contractor, or a previous tenant, this is a good moment to think about rekeying the lock so that older keys stop working. Third, do you have a good spare? A key that has snapped once is telling you it is worn out. Do not cut the next copy from a worn key. Cutting from the original or from a fresh code gives a stronger result, and our key duplication page explains how we do it.
None of this is an upsell. It is a list of the things we would think about if it were our own door.
How do you keep a key from snapping again?
A few habits make a real difference, and none of them cost anything.
- Replace keys that look worn, bent, or thin at the shoulder before they break. A key that has started to bend will not last.
- Do not copy copies. Each generation drifts a little from the original cut and makes the lock work harder.
- If a key suddenly feels stiff in the lock, stop forcing it. Stiffness is the lock telling you something is wrong.
- Do not use your house key to pry, scrape, or open packages. The blade is a precision part.
- Keep a spare in a secure place so a break is an inconvenience and not a lockout.
- Have sticky or gritty locks looked at. A lock that has to be forced is the lock that eventually breaks a key.
What should you ask any locksmith before they start?
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 you call for their license information, and check it with the state. Ask also whether they work for themselves or pass jobs along to a subcontractor, and ask for the cost factors before work starts. A reputable company will answer these questions without hesitation.
If you are in Beverly Hills with a key stuck in a lock right now, call (213) 577-1366. We answer at any hour, and we will walk you through what to do while help is on the way.
Frequently asked questions
Can you remove a key that broke off flush with the lock?
Often, yes. A flush break means there is nothing to grip from the outside, so we use thin extractor tools that slide alongside the blade and catch the cuts of the key. It takes more care than a protruding fragment, and sometimes the cylinder has to come out of the door to reach it, but a flush break is not the end of the lock.
Will extraction damage my lock?
The aim is to pull the fragment without harming the cylinder, and in most cases that is what happens. Damage is more likely when the lock has already been forced, glued, or pried at before we arrive. If we find wear or damage inside, we tell you before doing anything else.
Is it cheaper to extract a broken key or replace the lock?
Extraction is usually the more economical route because you keep the hardware you already own. The exception is a lock that is worn out, damaged, or no longer worth saving. In that case we say so, and you decide between repair, rekeying, and replacement.
My car key broke in the ignition. Can you handle that in Beverly Hills?
Yes. We extract broken blade fragments from ignitions and door locks. Whether the key has a transponder chip and how a replacement needs to be made depends on your vehicle, so we confirm by VIN and in person. Some vehicles are dealer-only for certain key types, and we tell you if yours is one.
Should I try to pull the broken key out myself with tweezers or pliers?
If a good piece sticks out and you can grip it gently and pull straight, you might succeed. If it moves even slightly in the wrong direction, or you cannot grip it firmly, stop. Pushing, twisting, or prying can shove the fragment deeper and bend pins. When in doubt, call us before you try.
Can a broken key be duplicated or used to make a new one?
Often it can. If we have both halves, or a key cut that can be read from the fragment, we can use that to cut a new key. A worn key is a poor template, so if the original was in rough shape we may suggest cutting from a fresh code instead.
Does a broken key mean I should rekey my locks?
Not by itself. A snapped key does not make a lock less secure. But if the broken key was an old one that many people have held, or if you are unsure who has copies, rekeying is a sensible step once the fragment is out.
Do you serve all of Beverly Hills, including 90210, 90211, and 90212?
Yes. We serve all three Beverly Hills ZIP codes, along with nearby hillside and adjacent areas. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, and our mobile vans come to your door.
