If a vehicle equipped with the LoJack® System is stolen, the owner reports the theft to law enforcement.


Once the theft is recorded in the national stolen vehicle database, the vehicle's LoJack® unit is activated*, emitting a uniquely coded Radio Frequency signal to a network of law enforcement cars and aviation units. 


Law enforcement use LoJack Tracking Computers installed in their vehicles to pick up the signal being emitted from the stolen vehicle. Vehicles can be detected in areas such as garages, shipping containers or dense foliage, where other systems may be less effective.


*LoJack unit activation is contingent on vehicle being located within LoJack's coverage area that spans counties across 29 states in the U.S.  See for details.
