    Just yesterday both my key fobs stopped working. Ive replaced both fob batteries and still nothing. My dash light flashes when car is off and turns off when running. I find it hard to believe that it was my batteries as they were working no problem all this time. This problem is driving me crazy. Any help is appreciated. Thank you

    what dash light if flashing? The truck is stock or has aftermarket remote start? The truck starts and runs fine, the truck battery is good?

    The light with truck and lock on the bottom left of cluster. The truck has factory alarm and truck runs perfectly fine when on. I haven’t changed the truck battery but there’s a little corrosion on negative terminal. And voltage is close to 14 when running.

    so it is just an issue with lock/unlock when using the fobs?

    Yes exactly. I’ve changed batteries in both my fobs. I’ve tried the reprogramming method found online and nothing still. It worked once out of no where at very close range to my door and then nothing again

    For the hell of it, can you put a battery tender or charger on the truck and try again?

    Yeah I can put one on just to see. Would a faulty truck battery be the cause of this?
