Any suggestions on what lubricant is best to use for the door locks on the 2002 CRV? The driver's side lock is sticking and the key will not always go in. I have seen this thread discussed before, but never saw a specific suggestion on what lubricant would, hopefully, do the job. I want to try that first, before going through the hassle of replacing the cylinder.

 

Krown T40.

 

Graphite powder. They sell it in Home Depot/Lowes etc, near where they make keys.
