Key Broke Off in the Lock? Do This, Not That
Author : Choice City Locksmith | Published On : 18 Oct 2026
A key snapping off inside a lock is one of those small disasters that always seems to happen at a bad moment: leaving for work, arriving home late, or on a freezing morning. What you do in the next few minutes decides whether this is a quick fix or a bigger repair.
Stop and do not push
The most common mistake is trying to push the broken piece back out with another key or forcing something in after it. That usually drives the fragment deeper and can damage the pins. Leave the lock alone until you have a plan.
Can you see the broken piece?
If a bit of the key is sticking out, you may be able to grip it gently with needle-nose pliers and pull it straight out. Keep the lock in the position it was when the key broke; if the key snapped while turned, the piece will usually only come out once the cylinder is back in the starting position.
What not to use
- Superglue on a stick or the other half of the key. It can glue the pins and ruin the cylinder.
- Oily sprays. They make the fragment slippery and attract grit.
- Screwdrivers or knives to pry. These damage the keyway.
Why keys break
Keys usually break because they were already weak: worn thin, cracked, bent from being used as a pry tool, or turned in a lock that was sticking. A stiff lock is a warning sign. Fix it before the key gives out.
After it is out
Do not use the other half of the broken key to cut a copy if you can avoid it. A copy from a broken or worn key carries its errors forward. A new key cut to the lock's code works better. If the lock was sticking, have it serviced at the same time.
