The '''Lojack Stolen Vehicle Recovery System ''' is an aftermarket vehicle tracking system that allows vehicles to be tracked by police, with the aim of recovering them in case of theft. The manufacturer claims a 90% recovery rate. The name "LoJack" was coined to be the "antithesis of hijack", wherein "hijack" refers to the theft of a vehicle through force.
LoJack’s core business comprises the tracking and recovery of cars, trucks, construction equipment, commercial vehicles and motorcycles. However, LoJack is expanding into new markets through licensing agreements and investments in areas such as cargo security and people at risk of wandering (probationers, parolees, and Alzheimer's patients). LoJack Corporation claims that over 300,000 vehicles have been recovered worldwide since the product was introduced more than two decades ago.
