Why do keys break inside locks?
A key almost never snaps on a good day. It breaks because something has been building for a while: metal fatigue at the shoulder, a lock that has gotten stiff, a key that is a copy of a copy, or a bit of extra force on a turn that should have been easy. Brass keys flex slightly every time they are forced, and eventually the weak point gives way.
Where the key breaks decides how the job goes. A stub sticking out of the keyway is usually the simplest case. A key broken flush with the face of the cylinder, or pushed in past it, takes finer tools and more patience. Either way, the cylinder is a precision part with small pins or wafers inside, and the goal of broken key removal is to get the fragment out without scoring any of them.
This page covers a key broken inside a lock: a house door, deadbolt, padlock, mailbox, gate, or a car door or ignition. If the key is simply lost and you are locked out, that is a different job with its own approach.
What should you do right after a key breaks in the lock?
The first few minutes matter, mostly because of what not to do. Most of the extra damage we see comes from well-meant fixes made in a hurry.
- Stop turning. Forcing the stub against a stuck cylinder can bend the fragment or shear a pin.
- Do not push the broken piece deeper with another key, a nail, or a screwdriver. Deeper means harder to reach.
- Never glue the pieces back together. Glue that gets into a keyway can turn a quick extraction into a cylinder replacement.
- Skip household oil sprays. They gum up small parts over time and make extraction messier.
- Hold on to the part of the key you still have. We can use it to match the cuts when we make you a working key.
- If it is a car ignition, do not crank the engine or wrench the steering wheel against the lock.
How does broken key extraction work, step by step?
Every lock is a little different, but the method follows the same order, starting with the least invasive approach and moving on only when needed.
- We look first: which lock, which brand, how far the fragment sits, and whether the key made a clean break or a twisted one.
- We clear the keyway with a lubricant made for locks and check the position of the fragment with a small light.
- If the piece sticks out, we grip it with fine extractor tools and pull it straight back along the keyway without rotating it.
- If it is flush or deep, we use thin hooked extractors that catch the cuts of the key, working it out a little at a time so the pins are not scraped.
- If the fragment will not release, we take the cylinder out of the door or housing where that is possible and work on it at the bench, where we can see everything.
- We test the cylinder: pins or wafers move freely, the plug turns smoothly, nothing is burred. If the lock is worn past reasonable use, we say so instead of putting it back and hoping.
- If you need a working key, we cut one and test it in the lock several times before we leave.
- Then we go over what happened and what, if anything, should be done so it does not happen again.

A broken car key adds a layer a house lock does not have. Many modern keys carry a transponder chip, and the car may expect to see it. A snapped key can leave the chip in the part you are holding, in the part stuck in the ignition, or inside a plastic head that has split. Which of those applies depends on the vehicle.
We do not guess about chip and programming details. Whether a replacement can be cut and programmed on site, whether an existing chip can be reused, and whether a particular make needs dealer-level access varies by year, make and model. So we confirm by VIN and in person before telling you what is possible. If your vehicle turns out to be dealer-only for programming, we say so plainly rather than starting work we cannot finish.
An ignition cylinder is also tied into the steering column's anti-theft hardware, so we extract carefully and avoid prying. If the ignition itself is worn or damaged, that is a separate ignition repair job. If you need a new key once the old one is out, car key replacement picks up from there. A key broken in a car door lock is usually a simpler job than one broken in the ignition.
How much does broken key removal cost in Toluca Lake?
We do not put numbers on a web page because the honest answer depends on what is sitting in your lock. These are the things that move the cost:
- Where the key broke. A padlock, a mailbox lock, a deadbolt, a car door and an ignition each take different tools and time.
- How far the fragment sits. A stub you can grip is a lighter job than a piece lodged deep in the keyway.
- The lock itself. A standard pin cylinder is one thing; a high-security cylinder or an older mortise lock with an unusual keyway is another.
- Whether the cylinder has to come out and be worked on at the bench.
- Whether you need a new key afterward, and for a car, whether it needs chip programming.
- Whether earlier attempts, such as glue or forcing, have damaged the cylinder.
- The hour of the call and the drive to your address. Our storefront is in Westwood, and Toluca Lake is roughly 15 miles away.
What does a snapped key look like in Toluca Lake homes, condos and shops?
Toluca Lake is a small neighborhood, and its housing mix shapes the calls. The 1920s and 30s traditional and ranch estates, including the private shoreline homes in the Lake enclave, often run a blend of vintage hardware and modern retrofit security. An old brass key used for decades is a prime candidate to fatigue and snap, especially in an older cylinder that has gotten stiff. The area has standard southeast valley summer heat and no coastal corrosion, so what we expect to find is wear rather than rust. The mature tree cover that keeps some streets shadier and slightly damper in winter may leave older exterior locks a little stiffer, so a key that suddenly feels tight is worth taking seriously before it snaps.
Many estates are behind gates and hedges, and homes near Lakeside Golf Club are a good example of the gate and estate lock service we do. A key can break in a front door, a side gate, or a gate padlock. When the break is in a gate, we sometimes pair the extraction with gate lock repair so the same stiff lock does not break the next key. You or someone at the property will need to be able to let our van through.
Along Riverside Drive and the Cahuenga edge, low-rise condos and apartments mean a snapped key in a unit door is a common call. If the extraction goes sideways and you end up outside, apartment lockout service is the related job. Shops and restaurants in the Riverside Drive village district see their own version: a key that breaks in a storefront lock at closing or opening, when waiting is not an option.
We serve all of 91602, including the Lake enclave, the Riverside Drive village, and the adjacent West Toluca Lake, Toluca Woods and Toluca Terrace areas, with mobile vans out of our Westwood storefront.

Call (213) 577-1366What happens after the key is out?
Extraction is only half the job. A key snaps for a reason, and if the reason stays, you will be calling again. Once the fragment is out, we look at what led to it.
- A worn or fatigued key: we cut a fresh one from a sound original or from the lock's code where possible, rather than copying the weak key. That is the idea behind good key duplication.
- A stiff cylinder: we clean it, adjust it, or recommend replacing it, whichever fits the condition.
- A damaged cylinder: if the lock cannot be trusted any longer, lock replacement is the honest answer.
- A sound lock with old copies you no longer trust: lock rekeying changes which key works without swapping the hardware.
Why call Wilshire Lock & Key for a broken key?
We have been in business since 1987, and a snapped key is one of the oldest problems in the trade. We work from a storefront at 10740 Wilshire Blvd in Westwood and send out vans for mobile locksmith service across 140 cities in Los Angeles and Ventura counties.
You are dealing with one company, not a dispatch service that hands your call to whoever is nearby. David, the owner and lead technician, oversees the work. The phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round, because keys do not choose to break at convenient times.
Should the locksmith you call hold a California license?

Frequently asked questions
Can you remove a key that broke off flush with the lock?
Often, yes. A flush break takes thin hooked extractors and more patience than a protruding stub, but it is routine work. If the fragment will not come out in the keyway, we may remove the cylinder and work on it at the bench.
Will extraction damage my lock?
The point of the method is to avoid that. We work along the keyway so the pins are not scraped. Locks that were already worn, or that had glue or forced attempts, can be harder, and we tell you what we find before doing anything beyond the extraction.
Do I need a new lock after a key breaks?
Not usually. If the cylinder tests smooth after the fragment is out, it can stay. A new lock makes sense only when the cylinder is damaged, badly worn, or you want a different type of hardware.
Can you get a broken key out of a car ignition?
Yes, we do broken car key extraction on ignitions and door locks. Whether a replacement key can be programmed on site depends on the vehicle, so we confirm by VIN and in person. If a make is dealer-only for programming, we tell you straight.
Can I glue the key back together and use it?
Please do not. Glue can run into the keyway or the cylinder and seize it. A glued key also tends to break again at the same spot. Keep the pieces and let us use them to make a proper key.
Do you come to gated estates and condos in Toluca Lake?
Yes. For gated properties, someone needs to be able to open the gate or give us access. For condos along Riverside Drive, we come to your unit door the same as any other address in 91602.
What if the key broke in a padlock, mailbox or gate lock?
Those are common and usually quicker than a deadbolt on a home. The method is the same: grip or hook the fragment, pull it straight out, and test the lock. Small, cheaper padlocks sometimes make more sense to replace, and we will say so.
Can you help a shop or restaurant on Riverside Drive?
Yes. A broken key in a storefront lock is a time-sensitive problem for any business, and we respond at any hour. We extract the fragment, test the lock, and let you know if the door needs repair before the next day.
How do I find out what it will cost?
Call (213) 577-1366 and describe the lock, where the key broke, and how much of it you can see. Cost depends on the lock type, the position of the fragment, whether a new key is needed and the hour. We explain the situation before work begins, so you decide.
