Hi there,

I have replaced many door locks in Commodore.

Yours sounds like the lock mechanism is frozen.

I've had a few where a light rap on the outer door skin while pressing lock/unlock will release the lock actuator.

Does the door lock knob feel normal or hard to operate?

The light rap on the door skin doesn't work. The door handle feels normal

Gary is there a trick to open the door... If I can open the door I can pull the internal door skin off and see what's going on

Hi Sean,

There is no trick as such.

When it gets to this stage, I remove the inner door handle and lock snib button, the the top of the door trim can be manouvered off the inner frame, to gain some access to the lock.

With a mirror, long flatblade and a light, flick the lock actuator to the opposite position.

Then the door should open.

The hard part is getting the door open.

The door trim then needs to be off to replace the lock assembly.

Hi Sean,

I hope my advice has been of assistance to you.

I have never had a door I can't open.

I would get it open for you if you were local to me.
