Another GU drivers door problem.

[Cuppa]

I replaced the drivers door lock mechanism with a new unit because I was concerned that it was on the way out after experiencing a couple of times when the key would not unlock it.

I couldn't see anything wrong with the old mechanism, & the key behaviour has remained much the same - ie need to turn it one way & then the other to unlock. Today I experienced the same problem which led me to replacing the mechanism. Put the key in to unlock the drivers door & couldn't turn the key at all, in either direction. Jiggling the key made no difference, I had to unlock the passenger door (key worked smooth & problem free), climb in & unlock the driver door from inside - whch worked perfectly normally. I then retried the key in the driver's door & it worked ok as it usually does for several locking/unlocking cycles, & then 'jammed' again.

Any thoughts as to what is going on?

Maybe the barrels getting worn out???

Are barrels replaceable utilising the same key, or does replacement mean having to have a separate key just for the driver door.

If it is wearing out it doesn't say much for the quality of the barrel. I've had much older cars which have had far more use & have never had a barrel wear out before.

I've been experiencing the same thing. Not always but sometimes.

every now and then used to feel it catch when turning and yep had to do the jiggle etc, .. Ended up puting in central locking a few weeks ago so keyless now and its great.

Had same prob with mine too. Changed mech too late tho = hours of fun.
Apologies if asking obvious...
Do you have a spare/master key? Maybe current key is worn?
I'm using a new-ish non-genuine key for the door/ignition, so this may be how I actually fixed prob after mech change - only vaguely recall getting it cut - it was a while back!

how old is the key it may be that worn its not picking up the small tumbler thinghies
A locksmith would be able to key it alike
Your key would have a number wouldn't it???

EDIT:: is this just a DX problem or does it effect other models??

A sign of the times , things arent made to last these days its a recycle world we live in

The key does look a bit worn, but my spare which is noticeably less worn gets the same result. Besides both keys operate the passenger door as smooth as.
