Binding Lock Cylinders

Correct binding or sticking door lock cylinders or keys that are hard to insert by applying the proper lubrication.

DO NOT use penetrating lubricants (such as GM P/N 1052949 and WD-40(R)). These lubricants wash out the original lubrication and eventually evaporate, leaving little or no lubricating material.

IMPORTANT: Do not damage the painted surfaces.

1. Hold the lock cylinder shutter open using a paper clip or the equivalent.
2. Force air into the cylinder using compressed air and a blow gun attachment.
3. While you hold the lock cylinder shutter open, inject a small amount of lubricant into the cylinder.
4. Work the key into the lock cylinder several times.
5. Wipe away any excess lubricant from the key.
