Car Immobiliser System

The immobiliser system is the car’s built-in anti-theft system that prevents the engine from starting unless the correct key or transponder signal is recognised. It is a vital part of vehicle security. In the Carkeyhelper service, the System entry specifies the exact immobiliser type used in that particular vehicle, such as EWS3, CAS3, Immo3, or other manufacturer-specific systems. This information helps identify the correct programming method and compatible key type.
