Thread: Key FOB Doesn't Work

Think I might invest in a Nanocom. I'll have to look further into this one.

Anyway after that all my issues were gone. Never really figured out how to make sense of it all.

I had the terminals cleaned and a new battery put it in when I first got it. It shouldn't be that, but who knows.

Next time when the fob refuses to work after a longer rest unlock and lock back with key without opening the door then try again with fob cos the BCU goes to sleep and this trick wakes it up

I've got two fobs, but one fails to work (it used to), even after replacing the battery. Light still dhows up on the fob, but won't talk to the car. I haven't tried resyncing it yet, but seems odd that one would suddenly stop working.

This won't set off my alarm will it? Where is the fob receiver located in the car? Not quite sure where to find it in RAVE.

The alarm will not go off as long as you dont open the door but the BCU might wake up if that's the problem and the fob will work then, the receiver is in front of the rear sunroof under the roof lining bolted to the roof where it curves up ... see RAVE - alarm system and horn - repairs
