Directed Wegfahrsperren-Interface UNIVERSAL

The 556UW / 556U remote start interface module is used when installing
remote start products in vehicles equipped with a transponder or RF
(Radio Frequency) based immobilizer system. This type of system uses a
small chip imbedded in the ignition 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
556UW 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.
