Key Stuck or Snapped in the Lock: What to Do (and What Not to Do)
A key that will not turn, will not come out, or has snapped off inside the lock is usually a sign the cylinder or the key itself is worn. Here is how to handle it without making it worse.
If the Key Is Stuck but Not Broken
- Stop forcing it. Keys snap when they are twisted hard.
- Push the key gently all the way in, then wiggle it very slightly while pulling straight out.
- On a uPVC or composite door, lift the handle and push the door towards the frame, then try again — pressure from the locking points can bind the cylinder.
- If you have a graphite lock lubricant, a tiny puff into the keyway can help. Avoid thick oils that collect dirt.
If the Key Has Snapped
- If a piece is sticking out, you may be able to grip it with fine pliers and pull straight out, without twisting
- If it is flush with the cylinder, leave it — pushing with the other half only drives it deeper
- Never use superglue to try to stick the pieces back together inside the lock; it usually ruins the cylinder
Why Keys Get Stuck or Snap
- Worn keys, especially copies of copies, that no longer match the pins properly
- A worn or dirty cylinder
- A door that has dropped, putting pressure on the lock
- Using the key as a handle to pull the door shut
How We Fix It
We remove broken key pieces with specialist extraction tools, usually without needing to replace the cylinder. Extraction starts from £59 and usually takes under 30 minutes. If the cylinder is worn, we can replace it on the same visit — from £49 plus parts, or from £69 plus parts for a 3-star anti-snap cylinder. We do not offer key cutting as a standalone service, but any new cylinder comes with new keys.
Frequently Asked Questions
Can a snapped key be removed without replacing the lock?
Usually, yes. With the right extraction tools the broken piece can be removed and the original cylinder kept, as long as it is not damaged.
How much does broken key extraction cost?
From £59, usually done in under 30 minutes, with no call-out fee.
Should I use WD-40 on a stiff lock?
A thin spray can help short-term, but graphite or a dedicated lock lubricant is better. If a lock is regularly stiff, the cylinder is wearing and should be checked.
