my wife got her purse stolen sat. out of her car at her grandmothers house. well lost alot of her personal stuff , but also my other set of keys with alarm on it. well everybody knows my truck because i'm always changing wheels. her address + keys with alarm, not good!! well i havent had any prob, yet !! i had a old truck back in the day with alot of stereo stuff and rims, well my dad had a friend wire a kill switch, so you had power it just wouldn't turn the starter. well i went to a audio(alarms) place to day a the did it for me on my dodge. he first tried to sell me a $200 dollar alarm system,but i told him that all it's going to do is let me know it's gone and make it louder so i can here which way he went. really didn't think that was funning, but i did!! so he shut up and did it for me. just put a switch under the dash( out of sight) so if somebody breaks in they aren't going anywhere. all power, no starter!!! they may take everything in there but they aren't getting the truck or wheels.(cost $20. seeing my truck in my drive way- priceless).
