Type-3 Immobiliser

KAT Immobilizers are specially designed to operate under severe conditions of transportation industries, agriculture and construction vehicles.

The main purpose of KAT Immobiliser systems is to prevent theft of the vehicle by blocking the ignition system of the vehicle. 

The system consists of a control unit (ECU) containing the record of the transponder code, a switch with integrated transponder and an antenna. Alternatively, it is offered with a keypad. The immobiliser system comprises a master unit, a reader antenna and a switch with integrated transponder that is compatible to the KAT Ignition Switch.  The antenna and switch with integrated transponder fulfill their function without the need for an external power source.

KAT Immobiliser models are offered to our customers with certifications obtained from international institutions as a result of meticulous work and a long testing process. The KAT immobiliser systems are offered as 4 separate types according to their hardware specifications.
