2002 Silverado LT -- my key fob stopped unlocking the doors, changed battery, no improvement, got my spare, it didn't work either, changed battery, still didn't work, it seems as if a fuse or whatever relays the signal has stopped working, any help would be greatly appreciated. Thanks Dennis

 

Did you try to reprogram it?

 

No I didn't reprogram it, it's the original one that came with the truck, and how do you reprogram it?
