Broken Key Extraction in West Hills, CA

What is broken key extraction, and when do you need it?

Broken key extraction is the job of getting a snapped piece of key out of a lock without damaging what is inside. That might be a front door deadbolt, a side-gate lock, a padlock, a garage entry door, or a car door or ignition. The cylinder holds small pins or wafers that have to line up precisely, and a careless attempt to dig out the stub can bend or scar them. Done properly, the lock keeps working afterward and you are not forced into a replacement you did not need.

Most calls begin the same way. You turned the key, felt it give, and now you are holding the bow (the head) while the blade is still in the lock. Sometimes the stub sticks out far enough to see and grip. Sometimes it is flush with the face of the cylinder, or sits deep inside. People search for it as a key broken inside a lock, a broken key stuck in a door, or simply key broken in lock, and the fix depends on how much metal is left and where it is lodged.

If you are also locked out because the key was the only way in, that is a related but separate problem. We cover it on our house lockout page. In practice the two jobs often happen in a single visit, but we handle them as distinct steps.

Why do keys snap in the lock?

A key rarely breaks without warning. Almost every snapped key has a history, and knowing it helps decide how to prevent the next one. Brass is a fairly soft metal, and it fatigues the way a paperclip does when you bend it back and forth. After thousands of turns, a hairline crack forms near the shoulder of the key or at the weakest cut, and one more twist finishes it.

• Age and wear: a key used daily for decades, especially on original hardware, can crack at the shoulder or at a deep cut.
• Copies of copies: a duplicate cut from another duplicate drifts from the original specification, so it binds in the lock and takes more force to turn.
• A stiff or dirty lock: grit, old lubricant, or worn internal parts make the key work harder, and the key is usually the part that gives out first.
• Extra leverage: turning with a pliers, a keychain full of weight, or a hard twist on a sticking deadbolt puts more stress on the blade than it was made for.
• Binding doors and gates: when a door or gate sits out of alignment, the bolt drags on the strike and the key has to overcome that friction.
• A bent key: a key that has been slightly bent often catches on the way in or out and snaps when forced.

How we remove a broken key, step by step

The method depends on the lock type, the key material and how much of the blade remains. The sequence below is how most extractions go. It starts with the least invasive approach and moves to heavier methods only when needed.

1. Assess before touching anything. We look at the lock brand and type, how far the broken piece sits, and whether the lock turns at all. This tells us which approach is likely to work and whether the cylinder looks worn or already damaged.
2. Clean and lubricate lightly. A small amount of the right lubricant, not household oil, can loosen a stub that is wedged by debris or friction. The wrong product can gum up the pins.
3. Try the gentle pull first. When part of the blade is exposed, we use fine extractor tools designed to grip the serrations or the cut edges and draw the piece straight out along the keyway.
4. Use a keyway extractor for deeper pieces. When the stub sits back from the face, thin hooked or barbed tools slide alongside it and catch it so it can be drawn out without pushing it deeper.
5. Work the plug if needed. On some locks, turning the plug slightly with a tension tool relieves pressure on the broken piece so it releases.
6. Remove the cylinder only as a last resort. If the piece is jammed or the lock is already damaged, we may take the cylinder out of the door and work on it on the bench. This is slower but protects the surrounding hardware.
7. Test the lock and confirm what comes next. Once the piece is out, we test the lock with a good key or by picking it. If the lock is worn, we tell you plainly whether repair or replacement makes more sense.

What about a broken car key or a key snapped in the ignition?

Broken car key extraction follows the same principles but has a few extra wrinkles. A snapped key in a door lock usually means working in a small keyway with limited access, and the door's inner linkage has to stay intact. A key snapped in an ignition is a different job: ignition cylinders are tight and may be tied to anti-theft systems, so the piece has to come out without forcing anything that could affect the column or the electronics.

Many modern keys contain a transponder chip, and whether the chip is in the part you are holding or the part still in the cylinder varies. We do not guess at that. What your specific vehicle needs for a replacement key, and whether it can be cut and programmed by a locksmith or has to go through a dealer, depends on the make, model, year and often the VIN. We confirm that by VIN and in person rather than quoting from memory, and if your vehicle turns out to be a dealer-only case, we tell you so honestly rather than start a job we cannot finish.

After the broken piece is out, there are usually follow-on steps. If the ignition cylinder was damaged, our ignition repair service covers that. If you need a working key afterward, that falls under our automotive locksmith work. We keep these as separate tasks so you know what each one involves before agreeing to it.

What should you do, and not do, before we arrive?

A few minutes of restraint can make the difference between a simple pull and a cylinder replacement. Here is what a seasoned locksmith would tell you over the phone.

• Stop turning the key. If a piece is already stuck, extra force can push it deeper or damage the pins.
• Do not try superglue to reattach the key. Glue in a keyway turns a manageable problem into a ruined cylinder.
• Do not push the stub in with a nail or screwdriver. It usually seats the piece farther and bends the internal parts.
• Keep the broken pieces, both halves. They show the cut pattern and help us make a replacement key more accurately.
• Note the lock brand if you can see it on the face of the lock or the key bow.
• Tell us if the door or gate was sticking before the key broke. It points to alignment trouble that may break the next key too.
• For a car, leave the ignition alone and do not try to start the vehicle with the remaining piece.

How much does broken key extraction cost in West Hills?

We do not quote a figure on a web page because the honest answer depends on the situation. What we can do is explain what moves the price up or down so nothing about the quote surprises you.

The biggest factor is how the key broke. A stub standing proud of the lock face is a quick job. A piece sitting deep in the keyway, or one that was snapped and then pushed in with improvised tools, takes more careful work. Next is the lock itself: a basic residential deadbolt is generally more straightforward than a high-security cylinder with tight tolerances or a car ignition. Whether the cylinder must be taken out of the door matters too, as does whether the lock survives. If it does, you are done with the extraction. If it does not, repair or replacement becomes a separate decision.

Time and place also count. A call at night, on a weekend or from farther out takes more of our day, and West Hills sits about 23 miles from our Westwood storefront, so our mobile vans make the drive to you. We will explain the cost structure on the phone, give you an honest estimate once we have seen the lock, and ask for your go-ahead before work starts. Often the extraction alone is the more economical route, and we will say so when it is.

Why call Wilshire Lock & Key for a broken key?

We have been in business since 1987, and snapped keys are something we have dealt with in nearly every kind of lock. David, the owner and lead technician, oversees the work, and the people who answer your call are part of the same company that sends the van. There is no dispatch middleman reselling your job to a stranger.

We run a storefront at 10740 Wilshire Blvd in Westwood and mobile service vans, so work that is better done on a bench, such as a stubborn cylinder, can come back to the shop while simple pulls are done at your door. Our line, (213) 577-1366, is answered 24 hours a day, 7 days a week, year-round.

One more thing worth knowing: California requires locksmith companies to hold a Locksmith Company license (LCO) from the Bureau of Security and Investigative Services (BSIS). Ask any locksmith you call for their license information before work begins. It is a fair question and a reputable company will not be bothered by it.

Broken keys around West Hills: what we see and where

West Hills is almost entirely residential, mostly 1950s to 1970s single-story ranch tracts on suburban streets, with larger and more private lots toward the Valley Circle Boulevard corridor and the hillside edge near Castle Peak. Because there is comparatively little multifamily housing, most of the locks here are detached-home hardware: front door deadbolts, garage entry doors and side-gate locks. That shapes the kind of broken-key calls that make sense for the area.

In the older tracts off Valley Circle Boulevard, original hardware has often been turning for decades. Worn locks and worn keys are a classic combination for a snapped key, and after we extract the piece, lock repair or a lock replacement may be worth considering if the cylinder shows its age. Near the Fallbrook Center and Platt Village areas, a key that snaps in the front door while you are heading out or coming home is the typical story, and if you are shut out as well, we handle that in the same visit.

Summers are hot in this far-west corner of the Valley, and homes along the western hillside edge take sun and wind off the open space. Heat can swell wood doors, particularly south- and west-facing entries, until the bolt drags against the strike and the key has to fight for each turn. If a key broke on a door that was already binding, extraction fixes the immediate problem, but the alignment deserves attention or the next key may snap too.

On the larger lots around the Shadow Ranch Park area and the El Escorpion Park and Castle Peak area, side-gate and garage-door locks are exposed to weather and are used constantly with the same key. A key snapping in a side gate, or a gate lock that has stiffened over the years, is just as likely as a front door failure, and for a gate lock that has rusted or seized, our gate lock repair work picks up where the extraction leaves off. We serve both ZIP codes in West Hills, 91307 and 91304, and our vans come to you wherever the lock is.

What happens after the broken key is out?

Getting the piece out is only half the job. Once the lock is clear, we test it and tell you what we found. If the cylinder turns smoothly and the pins are intact, you can keep using it. If it is worn or scored, we recommend repair or replacement and explain why, so you can decide.

You also need a working key. If we still have the broken halves, or you have another working key, we can cut a new one, and our key duplication service explains how copies are made. A tip from long experience: do not copy from a badly worn key. Copy from a fresh one cut to the original specification, and keep a spare somewhere safe so one failure does not become a lockout. The same principle applies to your whole set. If one key snapped from wear, the others are likely heading the same way.
