2003 C1500 key fob quit. Put new batteries in, nothing. Tried reprogramming, nothing. One quit a year ago, second quit last month. Any help? Fuse? Something?

I don't know if you have tried the keyless entry resync procedure? It is below.

Yes tried that several times. Is their a fuse? Or computor master control? If so, where? I'll check the wiring.

The transmitter sends a signal to the passenger door module, that module sends signal to bcm, the bcm performs its function.

Yes there is a fuse, diagram below.

I tried the reprogram you suggested, no help. But my son suggested leaving the battery unhooked for 30 minutes or so, I tried that, to reset all the computors, and then tried your reprogramming procedure after I rehooked the battery. It worked. Took 2 times, but the key fob works again. Thank you
