A while back i posted that when winter hit and it became single digits my keyfobs stopped working and then it warmed up and they worked again. Well its been in the high forties low fifties for two weeks and the keyfobs no longer work. Ive checked the batteries and both are above 3V, I tried to reprogram them to the truck with no response, i checked the manual and there is no listing for a relay or fuse for the keyless system. So whats next? I did install one new battery and that didnt help either, and my wireless door fob does not work either even after a new battery also

 

You can get a set of those fobs for 10 bucks. I would start with replacing those.

 

The one is less than six months old that i bought at my dealer

 

Did the truck go into programming mode when you tried to reprogram the remotes or did nothing happen when it was in program mode and you pushed a button on the remote

 

Truck went into program mode but when i got to the keyfob part nothing happened which has me stumped. One brand new batery, other two are good at over 3V, one keyfob less than six months old, one original and one approximately three years old, truck goes into program mode but doesnt respond to keyfobs
