that's what i was thinking, so wouldn't you want it inside the car or an easily acces but secret area, rather than under the LP?
I was watching the Show "it takes a thief" and the installed something on a boat that kills the ignition over the internet/cell phone. The guy got a text message from anywhere if the boat started up when the system was armed, and he could shut it down if he needed. it also tied in with GPS tracking he could monitor over the internet if it was being towed away and not started...i don't know if it was a loJack system or not though.
