DIRECTED DEI 455G DOOR LOCK INTERFACE

Description

The 455G interface operates many functions of the lock/security system in the 2002 and 2003 model years Chevrolet Trailblazer, GMC Envoy, and Oldsmobile Bravada. The 455G converts the signals from keyless entry, alarm, and remote start systems into signals that can be understood by the vehicle’s data bus. This allows interfacing with the factory security and lock system through the data wire in the vehicle. The 455G controls door lock operation including locking, unlocking, and driver’s door only unlocking. The 455G also provides control of the factory security system. The factory security system can be armed and disarmed when locking or unlocking the doors or disarmed when remote starting while leaving the doors locked. The dome light and headlights will illuminate when the unit unlocks the doors depending on the vehicle model and trim level.
