Door Lock

I have been having trouble with my driver side door for awile now. It locks fine but then when I go to unlock it, it refuses to unlock. I have tried the key and the button inside. This is a 1992 Toyota Camry. If anyone has any suggestions or needs more information just post. Thanks.

Welcome to the forum!
Considering the age of your vehicle it is either lack of lubrication or warn parts. I would try to remove the decorative panel and see if you can just lubricate it.
Good luck,

Sam

Thanks for the response. I have already taken off the decorative side panel and lubricated the parts. It acts like it is electricaly locked. Is there a way to disconnect it electricaly so that the key will work? There is a plastic cover over the electrical mechanism inside, is there a way to remove this?
