A key that snaps off in the lock feels like a disaster, but it's usually a quick fix, and most of the time the lock survives. Here's what to do.
What not to do
- Don't push the broken piece back in or try to turn the lock with the other half of the key. That jams it deeper.
- Don't use superglue on the key. If it runs into the lock, the lock is usually finished.
- Don't force the door. A damaged door or frame costs far more than the extraction.
What you can try
If part of the key is sticking out, grip it with needle-nose pliers and pull straight out, without twisting. If it's flush with the lock or further in, leave it. Keep the other half of the key: it helps us cut a new one.
Why keys snap
- The key is worn thin, often a copy of a copy.
- The lock is stiff or binding, so the key gets forced.
- The key gets used as a handle to pull the door shut.
- Salt air near the coast seizes cylinders over time.
What we do
We remove the broken piece with extraction tools, usually without damaging the lock, and check why it happened. We cut a fresh key from the lock rather than from a worn copy. If the lock itself is binding, we service or replace it so it doesn't happen again.
What it costs
Our call-out is $120 + GST, which covers travel and the first 15 minutes on site, then $30 + GST per 15 minutes. Standard keys are $15–$25 + GST each. We confirm a fixed quote before any extra work.
