well, like stated it only takes seconds to put in a van or the back of a truck. but poping the ignition is the preferred method in my experience. wheel locks and kill switches have certainly worked with many. its not full proof but for the amateur it will stop most.
Lo-Jack is available in Virgina and has over a 90% recovery rate. trust me Lo-Jack works and that 90% recover is exactly what it is. when we get a Lo-Jack hit on a motorcycle its recovered that day almost every time and works far better then GPS locating systems because its radio frequency based and does not rely of satellite tracking which once put into a truck or garage will not work for chit. it works off radio (RF) carrier frequency of 173.075 MHz.
and the beauty of Lo-Jack is once we identify a hit say inside an apartment complex we have hand held Lo-Jack devices that work with in (10) feet so if someone puts it in an elevator and goes up to the 6th floor for example and rolls it into their apartment to strip it we will know which apartment it is.
