Subaru Key Systems
Subaru employs a wide evolution of key technologies, from early mechanical blade keys paired with simple immobilizers to advanced Smart Key systems with encrypted proximity authentication. The immobilizer architecture involves communication between the key, antenna coils, the ID box/immobilizer module, the BCM or Smart Key ECU, and the engine control module. Every “start permission” is granted only when the transponder response matches authorized records stored in non-volatile memory (EEPROM/Flash). Modern Subaru platforms also introduce Smart Keys with proximity antennas, LF/RF communication, encrypted challenge–response systems, and multi-module synchronization.
