Bypassing GM vehicle anti-theft systems (VATS)

Vehicles with the GM VATS (Pass Key) systems have a resistor embedded in the

ignition key. If the VATS decoder module does not measure the proper resistance

when the vehicle is started, the starter and fuel pump may be disabled for up

to ten minutes.

The VATS wires will be two very light-gauge wires coming out of the steering

column. The colors of the wires vary, but they are often contained in orange tub-

ing - either both will be white wires, or one wire will be purple/white and the

other white/black. Determine the value of the resistor in the key. Then follow the

diagram below to bypass VATS during remote engine start operation. If the BLUE

status output from the relay satellite has been programmed for factory security

re-arm, then use the (H3/5) BLUE/WHITE 2

status output from the control

module to control the relay.

Note: When connecting to the VATS wires, it is not important which wire is

cut.
