Broken key extraction in Sylmar, CA

What should I do right after a key breaks in the lock?

Stop turning it. That is the single most useful thing you can do. A key that has snapped is usually sitting in the lock with a few pins pressed against it, and every extra bit of force makes the problem worse. Most broken key stories that end in a replaced lock started with a second or third attempt to wrestle the piece out.

If part of the key is still sticking out of the lock, leave it alone for now. If you are holding the other half, keep it. It tells us a lot: where the key broke, how worn it was, and what kind of blank it is. It can also help us cut a replacement more quickly.

• Do not push the broken piece deeper with a screwdriver, nail or another key.
• Do not squirt glue, nail polish or anything sticky near the keyway. Glue on a key fragment is a much harder job than a plain snapped key.
• Do not keep jiggling the handle or turning the knob against the stuck fragment.
• Do not spray heavy oil in the lock. A light graphite or dry lubricant is fine, but wet oil collects dust.
• Do keep both pieces of the key and note whether the lock is on a house door, a gate, a padlock or a vehicle.

Why do keys snap inside locks?

A key rarely breaks for no reason. Brass is a soft metal, and over years of daily use it fatigues the same way a paperclip does when you bend it back and forth. The weak spot is nearly always right where the blade meets the head, or at a deep cut where the metal is thinnest. When something adds extra resistance, the key gives up at that spot.

The usual causes are fairly consistent from lock to lock. A worn key that has been used for years is the most common one. A copy made from another copy is next, because small errors build up and the cuts stop matching the pins, so the key has to be forced. Dirt, grit and dried lubricant inside the cylinder add friction. A lock that sticks because the door has shifted on its hinges puts side pressure on the key. And sometimes a key was simply bent earlier and nobody noticed.

If your broken key was a duplicate, it is worth thinking about how new copies get made after this. Cutting from a fresh, original-pattern key tends to give a smoother key than copying a worn one, and we cover that on our key duplication page.

How do we remove a key broken inside a lock?

Broken key removal is a hands-on trade job that mostly comes down to patience and having the right thin tools. We work through it in the same order each time so the cylinder is protected at every stage.

1. You call (213) 577-1366 and tell us what you can see: the type of lock, how much of the key is showing, and whether you still have the other half. The line is answered around the clock.
2. We come to you in a mobile van. For a padlock or a lock that can be taken off, you can also bring it to our storefront at 10740 Wilshire Blvd in Westwood.
3. We look at the keyway with a light before touching anything. We check how deep the fragment sits, which way the cut faces, and whether the cylinder is dirty, worn or already damaged.
4. If part of the key is sticking out, we grip it with fine extractor tools and pull straight along the keyway, letting the pins release as it comes.
5. If the fragment is flush or recessed, we use thin hooked or serrated extractor tools to catch the cut edges and draw it out without scoring the pins or the plug.
6. Once it is out, we clean the cylinder and check that it turns freely with a correct key. If the original key had worn out, we cut a new one so it does not break again.
7. We tell you plainly whether the lock is in good condition or whether it is worn enough that repair or replacement makes more sense.

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

A broken car key extraction follows the same idea, but vehicles add questions that a house lock does not. The broken piece may be in the door lock, the trunk, or the ignition cylinder. An ignition has a spring-loaded mechanism and often a steering-column lock behind it, so we work more carefully there and avoid pulling hard against it.

Getting the fragment out is only half of it. You still need a working key afterwards. Whether a replacement can be made from the lock, from the key code, or only with programming depends on the vehicle, and we do not guess about that. We confirm it by VIN and in person, and where a particular make only allows a dealer to supply the key, we tell you that honestly before you spend time on it.

If the ignition itself has been damaged by a worn or forced key, our ignition repair service covers that. If you need a new key cut after the old one broke, see car key replacement. If the replacement needs to talk to the car's immobilizer system, that falls under transponder key programming.

What affects the cost of broken key extraction?

We do not quote numbers on a web page, because two broken keys can be completely different jobs. What we can do is explain what moves the price up or down, so there are no surprises when we give you the figure on the phone or at the lock.

The biggest factor is how the key broke. A fragment sticking out of the keyway is usually the lighter-cost job. One that is flush, jammed deep, or bent can take noticeably more time. The type of lock matters too: a basic pin tumbler on an interior door is simpler than a high-security cylinder, a restricted keyway, or a vehicle ignition.

Other things that affect the cost:

• Where the lock is and what we need to bring to reach it, such as a gate, a padlock on a fence or a vehicle.
• Whether the lock has been tampered with, glued or forced before we arrive.
• Whether you need a new key cut afterwards and what kind of key it is. A plain brass key is different from a key with electronics.
• The hour of the call. Night, weekend and holiday work is a different situation from a scheduled daytime visit.
• Whether the cylinder is worn enough that replacement is the more sensible route once the key is out.

When extraction is not the right answer

Most of the time we can get the key out and the lock keeps working. Occasionally it does not make sense to stop there. If the cylinder was already failing, if the fragment came out but the pins are damaged, or if the lock is old enough that parts are no longer easy to find, putting the same lock back into service is false economy.

In that case we show you what we found and lay out the options. A worn lock can sometimes be fixed under lock repair. If it is past that point, lock replacement is the cleaner path. Extraction is the lighter-cost route when the lock is sound, and we say so when it is not.

Broken keys in Sylmar: what the area tends to throw at a lock

Sylmar sits in the northern corner of the San Fernando Valley, and the area has some conditions that are hard on keys and cylinders. Summers run very hot, and that heat can warp wood doors and loosen weatherstripping. A door that has swollen or shifted binds the bolt against the strike, and a key turned against that binding is the one that snaps. Strong Santa Ana winds also funnel through Newhall Pass and the foothill canyons, pushing dust into outdoor padlocks and gate locks. A gritty lock that is stiff to turn is a warning sign that a key is close to breaking.

Take the properties near the foothills, including the El Cariso area and the stretches near Kagel Canyon. Larger lots here often have perimeter gates, long driveways and detached garages, and horse-keeping parcels rely on padlocks and gate locks that sit outside all year. When a key snaps in one of those, you may be standing at the far end of a driveway with the fragment in a dusty lock. We bring the extractor tools to you, and the gate lock repair page covers what happens if the gate hardware needs more than a key pulled out.

Closer to Foothill Boulevard, there are newer gated townhome and small-lot developments, and the Foothill Boulevard corridor is a place where a front door lock or a gate lock may be getting heavy daily use. The Hubbard Street corridor and the Polk Street area are more typical of the postwar through 1980s tract homes, where original door hardware may still be in use and the keys cut for it may have been copied several times over. Those are the situations where a worn copy gives up in the lock.

Commuters matter here too. People who leave a car at the Sylmar/San Fernando Metrolink station and come back to a snapped key in the door or ignition are working against a train schedule, and that is a good reason to call a mobile locksmith rather than try to fix it yourself. Whatever the address in 91342, tell us the nearest cross street and what the lock is attached to, and we will plan the visit from there.

Our storefront is in Westwood, about 24 miles from Sylmar, and the mobile vans are what we use to cover this area.

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. David, the owner and lead technician, oversees the work, so what you get is a person who knows what is happening inside the cylinder, not a script.

We are a single company with a storefront and our own mobile vans. When you call, you reach us, not a dispatch middleman who passes the job to whoever is available. That matters for a delicate job like this, because the person who describes the problem on the phone is working for the same company that arrives.

One thing to do with any locksmith, including us: ask about the license. California requires locksmith companies to hold a BSIS LCO license, and you are entitled to ask to see it. A company that dodges the question is not one to let near your lock.

If you are weighing up other emergencies as well, our emergency locksmith page explains how we handle urgent calls in general. For this problem, the quickest step is to call (213) 577-1366 and describe what you see.
