IMMOBILIZER ANTENNA. An immobilizer antenna is an electronic component of the vehicle anti‑theft system designed to communicate with the transponder chip embedded in the ignition key or smart key. The antenna generates an electromagnetic field that activates the transponder and receives its identification signal, which is then transmitted to the immobilizer control unit or engine control module for authentication. If the code matches the authorized key stored in the system memory, the vehicle allows engine start and normal operation. The antenna is typically designed as an induction coil module installed around the ignition switch or integrated into the start‑stop button or steering column assembly. Proper operation ensures reliable key recognition and secure vehicle protection against unauthorized engine start. Failure symptoms may include engine start blockage, intermittent key recognition, immobilizer warning messages or diagnostic errors in the security system. The catalog includes genuine OEM immobilizer antennas, quality aftermarket modules and tested used components without connector or housing damage. Used parts are inspected for coil integrity, connector condition and signal functionality. Selection is performed by VIN number, immobilizer system type and part number. Timely replacement ensures reliable key authentication and proper operation of the vehicle anti‑theft system.
