i like it how i have to use the remote, means any tool using a screwdriver in my door lock my alarm goes off.. okay back to topic with kill switches, i agree, no point having one, i install kill switches in the commo fuel pump circuit, its a pretty flashy kill switch, its a button u press, and kinda activates a relay for a delayed time, rather than holding a button or flicking a switch.. cars are geting harder to steal anyways with immobilisers and stuff btw, the guy who installed my alarm did a flash job, i said i want the loudest siren and stick in under the dash, so if it goes off it deathens the theif, he said not allowed :( there is a dB limit :(
