Guys, several alarm systems on the market can operate door locks and a trunk release if you so choose ... You can also get feature like turning on dome light when unlocking doors, blink park lights and other things... What you need to be aware of is if you have a starter interrupt circuit as part of your system. This prevent the car from starting if alarm is triggered. I point this out because, on some alarms, if it alarm fails ( or a fuse blow ) It will leave the circuit open and the car won't start. Check with your installer. When I installed the alarm/door lock system in my 55, I used connectors in the ignition circuit so that I could unplug alarm and replug the circuit in it's conventional state.
