I need suggestions for a car alarm system. This is for an older "easy to steal" GM vehicle that will be setting outside all the time. Although it will almost be under the street light, it will still be at risk. I purchased a Viper 350-2 to install but sent it back as it requires "dealer only" hand held device to program it initially. Or to make any changes to the system down the road. The vehicle has PDL. but is old enough that they do not support a remote. So I'd prefer a unit I could do a door remote lock and unlock. Remote start in not really something I need or want. I need a system with a loud alarm, to sense glass breakage, forced entry and these types of things. I already have a new alarm back up battery unit to install with the unit when I find one! Suggestions please??
