After finding out that the key doesn't work in the drivers door lock ( turns but no action) I took out the lock to find some broken parts in and around the tumbler.

Does anyone know where you can get these parts for the lock. ie spring extension post and other assorted items that are now broken.

The tumbler, remote and control box in the door work fine. If I turn the controller with a screwdriver the doors will lock and unlock and the windows will open or close as requested.

Any help would be greatly appreciated.
