A key that breaks off inside a lock leaves you with half a key in your hand and the other half jammed behind the pins. It happens in front doors, deadbolts, padlocks, car doors and ignitions, usually to a key that was already worn thin. Prime Locksmith Services removes the broken piece with purpose-made extractors, so the lock keeps working and does not need replacing.
Because we work from a fully equipped van, we can also cut you a new key on the spot. In many cases we read the cuts straight from the broken pieces, so you leave with a fresh working key instead of a lock you are afraid to use.
For broken key extraction in St. Louis or any job for an automotive key locksmith in St. Louis, call (314) 745-4590.
















Careful removal first, then a new key so it doesn’t happen again.
Leave the lock alone. Every attempt with a pin or glue pushes the piece deeper.
We check how deep the piece sits and whether the lock was turned when it broke.
Thin spiral and hook extractors grip the key’s cuts and draw it out without harming the pins.
We cut a replacement on site, often decoded from the broken halves.
We test the lock with the new key and lubricate it so it turns smoothly.
Gluing a stick to the broken key almost never works, and when glue runs into the pins the whole lock has to be replaced. Tweezers and paper clips tend to push the piece further in. Leave it for the extractors.
