Sounds like some lubrication is in order. Just last week my locks played "not gonna work and you can't make me" when using the physical key. When using the remote they worked fine. Real head scratcher lol

 

Yeah these locks are mind boggling. I plan on popping off the whole door panel to see whats really going on. It will act up for weeks at a time and then will be completely perfect for the next few weeks. Tried lining up by the door latch and no luck. Any ideas were to apply lubricant for the door lock? Maybe it's getting caught or sticking when it decides to not cooperate and be stubborn. Right now, it's perfect *knock on wood*

 

Sorry I don't know I got them from a member here, and painted them myself this place can send you the proper color......http://www.automotivetouchup.com/
