I had a Crimestopper remote start and then I upgraded to a Crimestopper remote start with an alarm system. I installed it myself. It's not that difficult if you are somewhat knowlegable in automotive wiring. I have the model with a two way LCD remote. I didn't hook up the shock sensor. I just have the alarm to go off if my doors are opened. The flashing blue light on the dash should be enough of a deterent.
