In theory Lo jack is easy to defeat.
First find the frequency range used and make a radio transmitter that
transmits noise. This will prevent the receiver from hearing the lojack code
while
the car is in transit.
Next store the car in a Faraday cage. This is a steel cage that is grounded
so it prevents radio signals from escaping. This could be a all metal enclosed
trailer or a sea going shipping container.
When the car is being stored, use a field strength meter to locate the lojack
transmitter. There has to be a antenna near a window so just follow the wire.
Lastly, lojack only turns on when the car has been reported, this gives the
thieves a head start.
