My keyless entry has been work great till today. I started my truck b4 lunch break and locked it like i allways do, went to unlock it with the number pad on the door and it didnt do anything but just click on the last number.

Any ideas, I was thinking a ground?

 

Ive had a few at work that have been having problems with that there is a updated GEM-smart junction box reprogram for it. That's what controls the door locks and keyless entry among many other things!
