Drivers Door Won't Lock With Key

3 posts in this topic


I have a 2003 for Ka - it does NOT have central locking.

The drivers door will not lock with the key, however it locks fine from the inside - and can be opened with the key.

The passenger door opens/unlocks fine.

I've done some research and it leads me to believe the barrel may be worn?

I've read that you can replace the Tumblers (not even sure what they are).

Ideally, if any work needs to be done - I'd like to be able to use the same key.

Also - just a thought, approximately 3 months ago I had a similar issue with the boot - I sprayed in some WD-40 and that solved the issue.

Could my Key be worn? - What are the signs?

Thanks in advance for any advice.

A worn key is very likely. If the tip of the key is pointed and "sharp", then it's fine. But over time the corners wear down pretty badly until they're almost rounded off, and then they don't work right in the lock. Have you tested with a different key? If I remember right, any Ford key can lock any Ford.

(oh, and don't spray WD40 into locks - It's a muck magnet and will make the problem come back worse)

Found the spare key - it seems to work!

Saved me a few quid - money that I'm gonna invest in another key being cut I think.

Thanks for your help :)
