My lock and unlock switch on the key fob starting having issues about a month ago. I could unlock it but not lock it. Now both buttons stopped working. Just tried troubleshooting it. New fresh pair of CR2016s from Duracell. Didn't help. My leds are both lighting up as I push the buttons. So I tried a computer reset with ground on the positive side of battery to drain computers. When that didn't work tried reprogramming. Cannot get it to chip in programming mode after following the procedure of trunk open drivers side open and valet 5 times. Check continuity on the valet switch and its fine. The locks and alarm work fine if I use the key to lock and unlock. Chips too when I do it.

Any more ideas? Bad key fob? I've taken it apart and looked at the little PCB board under a micro-scope couldn't find any signs of damage.

 

You might post this on the X300 area as they are the same and you have more people on board

Thanks for the advice, I posted over there and then ended up figuring it out on my own. Was just a water damaged key fob. I didn't notice it when I replaced the microswitches the first time because damage was only on the back side of the PC board.
