To be honest, if any scumbag wants mine, they can have it!
As much as I like it, I do not want thieving scrotes waking me or my family up in the middle of the night with a knife to my throat demanding the anti hijack pincode or the location of a 'hidden switch'.
I always make sure the keys are somewhere easy to find in the house too...
Its a piece of metal, and it's insured.
But I agree, the standard alarm is very quiet!
