Spare Key Fob
I just bought a 2015 RAM 1500 ST. The spare key fob does not work! I got a
message saying "Wrong Key Fob". The emergency key inside the fob unlocks
the door though. Is there some activation that I have to preform in order to get it
to work? My manual is of no use. The fob shown in there isn't even like the
ones I have.
When the car says wrong key fob, the car is detecting the signal from a fob, and if it is the right fob, the signal isn't strong enough for the car to read it. You need to replace the fob battery and you might need to reprogram the car to that fob.
