In many cases, applying the proper lubrication can correct the following conditions:
• | Binding or sticking door lock cylinders |
• | Difficulty in inserting and removing the keys |
For lubricating the above components, use lubricant GM P/N 12346241 or equivalent.
Do not use penetrating lubricants such as GM P/N 1052949 or WD-40®. Penetrating lubricants wash out the original lubrication. Penetrating lubricants eventually evaporate, leaving little or no lubricating material. However, when using penetrating lubricants in order to thaw or in order to loosen the lock cylinder components, refer to steps 2-4 in the procedure below for the proper methods of lubrication.
Repair lock cylinders frozen in cold weather by using the following procedure:
Force air into the cylinders using compressed air through a blow gun attachment.
Wipe away any excess lubrication from the key.
