How to Extract a Broken Key From a Lock in 5 Minutes
Share
A broken key stuck in a lock is one of the most frustrating things that can happen — especially when you are locked out. But before you call a locksmith and pay $100+, try this yourself. With the right tool, it takes 5 minutes.
What You Need
A broken key extractor kit. These are small, inexpensive tools — usually under $20 — designed specifically for this job. They look like thin metal hooks or spirals that reach into the lock cylinder to grip and pull the broken key fragment.
Step 1: Don't Turn the Lock
If the key broke while turning, do not try to turn the cylinder further. This will push the fragment deeper and make extraction much harder. Leave the cylinder exactly where it is.
Step 2: Lubricate the Lock
Spray a small amount of WD-40 or lock lubricant into the keyhole. This reduces friction and helps the extractor tool slide in alongside the broken fragment.
Step 3: Insert the Extractor Tool
Slide the extractor hook into the keyhole alongside the broken key fragment, with the hook facing the key's teeth. Push in until you feel resistance from the fragment.
Step 4: Hook and Pull
Rotate the extractor slightly so the hook catches on the key's teeth, then pull straight out with steady, firm pressure. The fragment should slide out with the tool. If it doesn't come on the first try, reposition the hook and try again.
Step 5: If the Fragment Won't Come Out
Try needle-nose pliers if enough of the fragment is exposed at the keyhole. If the fragment is completely inside the cylinder, a spiral-type extractor works better than a hook-type — the spiral threads between the fragment and cylinder wall.
