problem with that is, there are many ways around it, alarms, fuel pump cutoff, iginition cut off, battery cutoff, so many ways that ppl know how to get around, now these days none of the above matters, if someone wants your shit, they are going to get it, best thing to my knowledge is low jack, why? because its going to take them too long to locate the module before they are caught, trust me, I know by personal experience (no I don't steal cars), they can take it, leave your crib, but won't even make it to the main roads before you track them.
