Abstract
There is disclosed a self-arming immobilizer system for immobilizing a vehicle. In an embodiment, the system comprises a signal input for receiving a signal indicating the absence of an authorized operator in a position of control in the vehicle; and an immobilizer unit adapted to receive the signal input, and in response to the signal indicating the absence of an authorized operator in a position of control in the vehicle, switch one or more relays to disable one or more circuits in the vehicle to immobilize and secure the vehicle. In an embodiment, upon arming, the immobilizer unit is adapted to passively disarm the vehicle upon detection of a first key fob within a defined first distance from a sensor located on the vehicle. In another embodiment, the first key fob is operable to wirelessly arm or disarm the vehicle from a defined second distance from a sensor located on the vehicle.
