help1. Understand the Problem

Keys get stuck when the bitting (the cut surfaces) no longer matches the pin chambers, or when a spring inside the lock breaks and jams a pin. Forcing the key can break it off in the keyway, making extraction harder. If the key will not go in all the way, the keyway may be blocked by debris or a broken key fragment.

Do not force the key - apply gentle sideways pressure to see if it releases

If the key will not come out, apply very light pressure in the direction the key naturally goes when turning (usually toward the door edge). Rock it gently. Never yank - if the key breaks in the keyway, you will need needle-nose pliers or a broken key extractor tool.

Spray graphite into the keyway and wait 5 minutes before trying againPowdered graphite works better than oil here. Spray it into the keyway, let it settle, and try turning the key very gently. The graphite reduces friction and can free a slightly jammed key. Try a slow rocking motion.

Use a broken key extractor tool if the key has snapped off insideIf the key broke in the keyway, buy a broken key extractor set (under $10 at any hardware store). The tool has a small hook that grabs the remaining key and pulls it out. Insert the extractor at the side of the keyway - not the center - and hook the key shoulder.

Remove the lock cylinder and check the pin springsIf the key still will not move, the pins inside the cylinder may be jammed. Unscrew the interior faceplate and remove the lock body. With the cylinder out, tap the cylinder gently on a wood surface to shake out any broken parts. Check the pin springs for breakage.

Copy a new key from the original if the key is wornIf the key is worn flat at the bitting, it may not align with the pin chambers. Find your original key (not the worn copy) and get a new copy cut from that. Worn keys get worse over time - replacement is the only real fix.

Replace the cylinder and get new keysIf the cylinder is damaged or the original keys are lost, replace the entire cylinder. Rekeying is cheaper than full replacement. Bring the lock body to a locksmith to have new pins cut.

Frequently Asked Questions

No. Oil-based lubricants attract dust and gum up pin chambers. Use powdered graphite only. It is cheap, available everywhere, and the correct solution.

What if the key broke off in the lock?expand_more
