Is there a fuse or circuit breaker got the keyless system? The thing doesn't work and I've looked in the owners manual and the fuse box and can't find anything. I wish I could get at the pad with a test light but I really don't want to remove the door panel.
Do the power door locks and the key fob work? I think they are on a common power supply. It appears all the logic for the keyless entry is done in the "Smart Junction Box," which also has connectors for other vehicle systems.
The keypad is connected to the SJB at connector C2280C, which also connects the door ajar switches. If the door ajar indicators are working, it would seem to rule out a lot of components, and narrow you down to the keypad itself.
