anyone help. when i try to disarm my clifford 600 nothing happens. the only way to do it is manually unlock the door then press the key fob and it disarms. the alarm operates correctly most of the time, just the odd day it does this, any idea what the problem is. any help would be greatful.

 

I've heard of someone else who had this problem, turned out to be inteference with the antenna IIRC. Probably best to get the dealer/installer to check it out I guess.

 

As above.

The 600 has a large antenna which needs sticking somewhere logical - mine was in the windscreen next to the a-pillar.

Get it checked out under warranty
