which is one of teh best car alarms out? my friend had a car alarm that would go off if someone tryed to see if the doors were open, and thats teh first thing someone is probably going to do if tehy try to jack your stuff, so i want a alarm that is pretty sensitive that will go off if you punch it lightly or jsut hit it and that has a keychain light or sound that will go off when the alarm goes off, so pretty much what i want is door handle sensors, keychain alarm, motion detector inside car and that is sensitive but not to sensitive~~!
Compustar/Nustart I would say is the best, both in reliability and functionality. Some vehicles will turn the interior dome light on when the door handles are pulled up on. Chances are your friend had one of these cars. What do you drive?
