I've got a standard alarm fitted to my car (says cat1 on the control module) and it also has a black box behind the centre console and the original siren.
I've been to the dealers and they can programme me a new fob which they will supply for around £80. I think its a fair price but they can't tell me what kind of functions the alarm has.
Does anyone know what that black box is? I think it may be a microwave sensor? as the red light on it still lights up when its behind plastic and I move infront of it.
And could someone tell me the functions. Ie does it chirp when I unlock/lock or full closure etc.
