555X Lexus/Toyota Transponder Kit

The Lexus Immobilizer system uses a low power transponder hidden in the plastic head of the ignition key. When the vehicle is started, the Key Cylinder Module converts the transponder signal and sends a secure, coded signal to the Engine Control Module. If the signal to the ECM is correct, the vehicle will start.

The 555X uses a unique auto-program sequence to learn the secure code from the Key Cylinder Module and repeats it when the remote start is activated, eliminating the need to leave the key in the ignition in order for the vehicle to start. The 555X Lexus Immobilizer Bypass Module integrates into the wiring for the Lexus Immobilizer anti-theft system to allow remote start capability, while still allowing normal function of the factory Immobilizer anti-theft system.
