My Chevrolet HHR has a remote lock/unlock clicker. About a year ago it would unlock but not lock the doors. What a PITA! I normally would lock the door as I was getting out of the car. Then there were those times when I'd wonder did I lock it? Walk back to check because, as you know, us full timers always have things we didn't want or have room for in the rig! Well, well, well! Today I decided time to order a new clicker.
Googled Chevy remote and saw a couple of 'you tubes' that looked interesting about repairing the remote. So I watched the one on how to clean the circuit board, but I had done that! Okay so re-do it! Still not working. So I watched the next one about placing small piece of foil at the position where the little button should touch the circuit board. Much like what my brother had me do when my solar powered hummingbird would not light up. It worked! I am a happy camper now.
