Hi there, i have a 2007 Chrysler Crossfire and the anti theft device goes off for no reason in very cold weather about 0 degrees and below. It is a factory fitted alarm from when the car was new. Do you know why it does this or what can be done to sort it out as my neighbours are not liking being woken up in the early hours. I have even tried taking the fuse out but as this also has an effect on the central locking i had to put the fuse back in.
