Alternatives to Volt Start?
I remember reading about an accessory kit for Fords which would watch the chassis batteries, was configured as a key in the Ford PATS system that would allow the engine to be started... but if the vehicle was put in drive or the brake pressed, the engine would be killed. This was to be as a security feature so the vehicle would have to have a "real" key inserted to have it move.
I did a quick search, found plenty of alarms, but none that will autostart on low batteries. Are they still being made?
