Locked my Fun up and the key moved round more than normal. Unlocked door now the key will not move the lock at all. Door still unlocks using button inside. Any idea what the problem is.....

It's the key lock inserts. The little pins and springs that lock & unlock the drum.

Take the lock out. A locksmith might fix it.

If a locksmith can't fix it does anyone know if the left and right barrels are interchangeable? If so you could move the good one to the driver's door for convenience.

The lock mechanism is side specific, but the barrel may interchange, I'm not 100% certain though I've never tried it.

If a locksmith can't fix it...

... he should start another business. I have more secure locks to my drawers. Felicia door 'locks' are a joke for thieves. And yes, barrels are interchangeable.

Took the door panel off,and what ever moves the rods on the end of the barrel has broken. The barrel it's self is fine. Thanks for all the info.....

Can you show us some photos of failed lock in case somebody else will have the same problem?
