Doors - Lock Cylinders Inoperative

Bulletin:

85-10-24

Date:

June 1985

Ref. No..:  85-271-10
SUBJECT:

DOOR LOCK CYLINDERS

MODELS AFFECTED:

ALL

Some vehicles may develop inoperative door lock cylinders. This may be characterized by difficulty inserting, extracting and/or turning the key.

These lock cylinders can be restored with the use of a silicone lubricant (GM Part Number 1052276 or 1052277).

NOTE:

Do not use any type of lubricant that contains chlorine on vehicles with a plastic cap around the lock cylinder as it may destroy the plastic.
