The 1100X/F-HA interface module is used when installing remote start
products in Honda/Acura vehicles equipped with a factory immobilizer.
The 1100X/F-HA allows for easy interfacing between the remote start and
the factory immobilizer, while maintaining the integrity of the OEM system.
The factory transponder-based anti-theft system uses a small electronic
chip hidden in the key to send a code to the vehicle’s transceiver
when the ignition is energized. The key must be placed in the ignition
and turned to the RUN position. This energizes a coil surrounding the
key, which in turn energizes the chip, which sends a code to the vehicle. If
the vehicle does not detect the code being sent, the vehicle will start and
then immediately shut off or will just crank, and the anti-theft light will
fl ash. The 1100X/F-HA provides a valid code to the vehicle whenever it is
remote started, but does not affect the immobilizer system during normal
vehicle operation; the immobilizer system remains fully functional.
