The 556U immobilizer interface module is used when installing remote start products in vehicles equipped with

an RF (Radio Frequency) based immobilizer system. This type of system uses a small chip imbedded in the igni-

tion key, called a transponder, to transmit a very low powered RF signal. This signal is picked up through an

antenna (or coil) around the ignition switch which is then sent to the immobilizer's transceiver. Once the correct

signal is received, the immobilizer will enable the ignition and/or fuel systems. If an attempt is made to start

the vehicle and the transceiver does not receive a valid code, the ignition and sometimes the fuel systems are

disabled. The immobilizer system will then render the remote start useless. The 556U bypasses the immobilizer

system only while the remote start is in use, maintaining the factory system's integrity. When the remote start

system is not in use the factory immobilizer remains fully functional.
