My P&J went in yesterday for an upgrade to the sound system,an amp in the boot and some significantly better speakers,a nice easy install you'd think. They rang me last thing yesterday to tell me that thy couldn't get the car started,so I'm assuming the immobiliser has kicked in somehow. Is there any sort of re set button/procedure for this?. I'm sincerely hoping they haven't knackered my car.Any ideas ato where to start? I'm going to their workshop later with the spare key in case that may work.
