Tonight as I got out of my truck, I touched the electric door lock button and closed the door. Ten minutes later when I came back, my key would not turn the key cylinder either way and I could not unlock the drivers door. I went around to the passenger door and the door unlocked as usual. Both side electric buttons will lock and unlock the doors, but if you pull the manual button located by my shoulder up and down it does feel different, a bit stiff and scratchy. Any ideas? I have not had a chance to look at taking the door interior panel off yet to see what happened.
