What does it mean when a key breaks off in the lock?
A key snaps when the force you put on it is greater than the metal can take. That usually happens at the weak point where the blade meets the bow (the part you hold), or somewhere along the blade where it has worn thin from years of use. The result is one of two situations. Either a piece of the key is still sticking out far enough to grab, or the whole blade is sitting inside the cylinder with nothing to hold on to.
Both are fixable, but they are not the same job. A stub that still shows at the face of the lock can often be gripped and drawn straight out. A blade that has gone flush or deeper needs thin extractor tools worked in along the keyway, and the work goes slower because the pins inside the lock are pressing on the broken piece. The way the key broke tells us a lot about how to approach it.
One thing worth knowing up front: a broken key is rarely a random event. Most of the time something was already wrong. The key was worn, a copy was cut badly, the lock was stiff or dirty, or the door was dragging so you had to lean on the key to turn it. If we pull the piece out and ignore that cause, you may be calling us again. So the job is not only getting the fragment out, it is also looking at why it broke.
What should you do right after a key snaps?
The first few minutes matter more than most people realize, because the most common way a simple extraction becomes a complicated one is a well-meant attempt to fix it yourself. Here is what to do and what to leave alone.
- Stop turning. Do not try the broken piece again to see if it will still work. Any more torque can push the fragment deeper or bend it.
- Keep the piece you are holding. The broken half in your hand shows us the key cut and the break point, and it can help us cut a replacement.
- Do not use superglue, a screw, or a nail to grab the fragment. Glue in a keyway is one of the hardest things to undo, and it can ruin a cylinder that would otherwise have been saved.
- Do not spray heavy oil or grease into the lock. A little dry graphite or a light lock lubricant is fine, but thick oil collects dust and gums up the pins.
- Do not hammer or pry at the lock or the door hardware. Forcing the lock usually costs more than the extraction would have.
- Check whether you have another way in. If a second door or a spare key is available, you may not need an emergency visit, and you can call us for a planned appointment instead.
- Call (213) 577-1366. Tell us the lock type (door knob, deadbolt, padlock, car door, ignition) and whether any of the key is still visible.

Call (213) 577-1366How does broken key removal work, step by step?
Every lock is a little different, but the process we follow is consistent. We start with the lightest-touch method and move toward more involved ones only when the lock demands it.
- We look at the lock and the fragment. We check the brand, how much of the key is visible, whether the lock turns at all, and what position the cylinder is in. A cylinder stuck partway through a turn is a different problem from one resting in its normal position.
- We clean and lightly lubricate the keyway with a product made for locks, so the fragment can slide rather than bind against the pins.
- We try the gentlest extraction first. If any of the key is showing, we use fine pliers or a pick-style extractor to get a grip and draw it straight out along the line of the keyway, without twisting.
- If the blade is flush or deeper, we switch to thin extractor tools. These are slender hooked or barbed blades that slip along the key and catch on its teeth or edge. We work them in carefully, set them, and ease the piece back out.
- If the fragment will not come free with the cylinder in place, we may take the lock apart. On many door locks, that means removing the cylinder from the door so we can reach the broken piece from the back or push the pins out of the way. This is still extraction, not replacement.
- Once the piece is out, we test the lock. We check that a working key turns smoothly, that the pins move freely, and that no metal shavings are left inside. If the lock was damaged or is badly worn, we tell you plainly and talk through the options.
- If you need a working key right away, we can cut one from the broken pieces or by the lock's code or from the lock itself where that is possible, and we will say honestly if a particular key cannot be duplicated on site.
What about a broken car key or a key stuck in the ignition?
Broken car key extraction follows the same basic idea, but there are more things that can go wrong, and we would rather be upfront about them than promise too much over the phone. A key snapped in a car door lock or trunk lock is usually a straightforward extraction, similar to a house lock. A key broken in the ignition is more delicate, because the ignition cylinder is tied to the steering column, and on many vehicles to the anti-theft system.
Whether a replacement key can be made on site depends on the vehicle. Some newer keys contain a transponder chip, and some have a remote built in. We do not guess about that over the phone. We confirm the key type by VIN and by looking at the vehicle in person, and we tell you honestly if your particular car turns out to be a dealer-only case for key programming. If it is, we say so rather than leaving you waiting on something we cannot deliver.
Sometimes the ignition cylinder itself is worn or damaged and the extraction is only the first step. When that is the case, the repair side of the job is covered on our ignition repair page, and the wider range of vehicle work is described under automotive locksmith service. For the key-extraction visit itself, we come to you with the van, so your car does not have to be towed to a shop just to have a fragment pulled out.

Call (213) 577-1366How much does broken key extraction cost in Mission Hills?
We do not quote numbers in an article, because an honest price depends on the situation in front of us. What we can do is tell you exactly what moves the cost up or down, so there are no surprises when we give you the figure on the phone or at the door.
The extraction itself is often the lighter-cost part of the visit. It gets more involved when the situation does.
- How much of the key is showing. A visible stub is usually the more economical case. A blade sitting flush or deep takes more time and finer tools.
- The type of lock. A standard residential knob or deadbolt is usually simpler than a high-security cylinder, a restricted keyway, or a vehicle ignition.
- Whether the lock has to come apart. If we can extract with the lock in place, that is a lighter job than removing the cylinder and disassembling it.
- Condition of the lock. A lock that is worn, dirty, or damaged inside may need repair or replacement after the key is out, and that is a separate decision that is yours to make.
- Whether you need a new key cut. If the original is gone entirely, producing a working key is its own step, and for vehicle keys it depends on the key type.
- Time of day and location. Night, weekend, and holiday calls, and the distance from our base, can all affect the total. We tell you how those apply before we start work.
- Whether we come to you. A mobile visit is the usual way to handle this, since a stuck door or an unmovable car cannot come to us.
Broken key stuck in a door in Mission Hills: homes, apartments, and businesses
Mission Hills is a mix of housing and business types, and a snapped key plays out differently in each. A big share of the neighborhood is 1950s single-family ranch tracts on modest lots, and original postwar door hardware is still common in homes that have not been remodeled. Old hardware tends to have worn keyways and tired pins, which is exactly the setting where a key that has been copied several times over the decades finally gives out. If you are in the streets near the Mission district around San Fernando Mission, or the Brand Park area, and a key has snapped in a front-door knob or deadbolt, that is a very common version of this call.
Along the Sepulveda Boulevard corridor, apartments are concentrated, and the typical scenario there is a tenant with a key broken in the unit door, often at night when management is not around. It can start as an ordinary apartment lockout and turn into an extraction once the key snaps in the lock. If you are locked out and not sure whether the key is broken or just stuck, our apartment lockout page explains how we handle that side of it. Newer townhome development near Rinaldi Street adds another lock style to the mix, and we work on those as well.
Businesses along the Devonshire Street corridor are a different case. Doors that open and close all day put real strain on locks, and when a door closer is out of adjustment or a door drags, a key is forced against a stiff latch and breaks. In that situation, pulling the key is only part of the fix, and a look at the closer is worth doing, which is covered under door closer repair.
Mission Hills sits in the north valley, with hotter summers than the basin and periodic Santa Ana wind exposure near the 118 corridor. That dry wind can dry out door seals and weatherstripping, and a door that no longer fits its frame well can make a latch bind and a key harder to turn. We do not blame the weather for every broken key, but when we see a door that fights the lock, we point it out. Whether you are in ZIP 91345 near the I-405/SR-118 interchange area or deeper in the neighborhood, we are about 17 miles from our Westwood storefront and come out in a mobile van.

Call (213) 577-1366Why call Wilshire Lock & Key for a snapped key?
We have been in business since 1987. Broken keys are one of the oldest problems in this trade, and the technique for getting one out cleanly has not changed much. What matters is patience and having the right small tools, not speed for its own sake.
We are one company, with a storefront at 10740 Wilshire Blvd in Westwood and our own mobile service vans. When you call (213) 577-1366, you are reaching us, answered 24 hours a day, 7 days a week, year-round, not a call center passing your job to whoever is available. David, the owner and lead technician, oversees the work. If you want to read more about how we handle night and weekend calls, see our emergency locksmith page.
One more thing we would like you to know. California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for their license information before they start work. That is a reasonable request from any customer, and a company that hesitates over it is worth thinking twice about. Also watch for anyone who quotes a vague low number on the phone and then changes it at the door, or who drills the lock right away. A broken key almost never needs drilling as a first move.
What happens after the key is out?
Getting the fragment out is often not the end of the conversation. Depending on what we find, you may have a few choices, and we lay them out without pushing you toward the biggest one.
If the lock is in good condition and the only issue was a worn key, you may be fine with a fresh, properly cut key. If the original key was a poor copy, a clean copy made from the right blank, covered under key duplication, often solves the root cause. If the lock is worn, sticky, or damaged from the break, replacing it is the more reliable route, and our lock replacement page covers that.
If the broken key has been floating around, or the house has just changed hands, rekeying can be a sensible next step. In Mission Hills, rekeys after home sales are a regular part of life in the ranch tracts, and our lock rekey service lets you change which key works without replacing the hardware. If the lock turns fine and nothing else is wrong, we will tell you that too, and leave it alone.
Frequently asked questions
Can you really remove a broken key without damaging the lock?
In most cases, yes. Our goal is to remove the fragment while protecting the cylinder, and it is the reason we start with the gentlest method. We cannot promise it every time. If the lock was already worn or damaged, or if the key was jammed hard, we may have to disassemble or replace parts. We tell you before we do anything that changes the lock.
What if the broken key is flush with the lock and nothing is sticking out?
That is still workable. When no part of the key is showing, we use thin extractor tools that slide along the keyway and catch the key's edge or teeth. It takes more care than a visible stub, and sometimes we have to remove the cylinder from the door to reach the piece, but it is a normal part of this work.
Should I try to pull it out myself with tweezers or a needle-nose pliers?
If a good length of the key is showing and you can grip it straight on, pulling gently along the keyway is reasonable. Do not twist, and do not keep trying if it does not move. Never use glue, and do not push anything into the lock that might wedge the fragment deeper. When in doubt, stop and call us.
Do you come to Mission Hills at night or on weekends?
Yes. Our phone at (213) 577-1366 is answered 24 hours a day, 7 days a week, year-round, and we send a mobile van. Night, weekend, and holiday calls can affect the final cost, and we explain that before the work begins.
My key broke in my car ignition. Can you handle that?
We can look at it. Ignitions are more delicate than door locks, and what happens next depends on the vehicle. We confirm the key type by VIN and in person, and we are honest if a specific car turns out to be a dealer-only case. If the ignition cylinder is worn, extraction may be followed by a repair.
Can you make me a new key after you pull out the broken one?
Often, yes. For a standard house key, we can usually cut a new one using the broken pieces or the lock itself. For car keys with chips or remotes, it depends on the vehicle, and we confirm what is possible by VIN and in person before telling you what we can do on site.
Will I need to replace the lock after a key breaks in it?
Not necessarily. If the lock is in good shape and the key was simply worn out, the lock often works fine once the fragment is gone. If the lock is stiff, damaged, or old and worn, replacement may be the more reliable choice. We tell you which situation you are in and let you decide.
How do I know a locksmith is legitimate?
California requires locksmith companies to hold a BSIS LCO license, so ask any locksmith for it before work begins. Also ask for the full cost explained up front, and be cautious if someone wants to drill your lock right away for a snapped key. A real extraction should start with the least destructive method.
