ALL cars come with a transponder-type engine immobiliser. The system has a micro chip in the key, relaying information the engine EFI and ignition computer via the immobiliser computer using a "rolling" or changing code. All Camry and Vienta models have remote central locking, illuminated entry and exit, and owner-programmable two-turn door unlocking. Camry VSX and Vienta models have a programmable auto lights-off extension timer, which can vary the time delay between zero and 60 seconds. The doors automatically relock after 30 seconds if the car remains unlocked and the doors unopened.
