Bypassing Factory Theft Deterrent

Systems

Many newer vehicles are now factory-equipped

with anti-theft systems that use either a resistor

coded key or a passive transponder that dis-

ables the fuel system unless a properly coded

key is inserted into the ignition cylinder. To inte-

grate a remote starter into these vehicles, you

must determine which type of factory anti-

theft system is equipped, then use the proper

bypass module for that system.

General Motors Anti-theft Systems:

Many late-model GM vehicles are equipped with

one of three basic anti-theft systems; Passkey,

Passlock, and Passkey 3. Standard Passkey sys-

tems are easily identified by the resistor chip

visible on the shaft of the key. Passlock systems

do not rely on a resistor equipped key. Instead

they use a resistance code generated when the

key is turned in the ignition cylinder. Both of

these systems have an anti-theft indicator in the

instrument cluster. To properly interface into

these systems and retain full functionality of the

factory anti-theft system,use the APV-1 module.

The Passkey 3 system, which is found on GM

vehicles 1999 and newer, is a transponder based

system (described below). Use the APP-1

module to integrate into Passkey 3 equipped

vehicles. This module allows full functionality of

the factory anti-theft system and requires the

use of a spare key.

Passive Transponder Systems:

Passive transponder systems have become the

most popular anti-theft system among vehicle

manufacturers (Ford, Honda, BMW, Toyota,

Nissan and others). This system requires use of

a tiny passive transmitter housed in the base of

the key.This device activates when placed close

to the vehicle’s ignition switch. The starter will

usually crank but the fuel system will be dis-

abled, mot allowing the vehicle to run, if the

transponder is not detected.To properly inter-

face into transponder systems, use the APP-1

module. This module allows full functionality of

the factory anti-theft system and requires the

use of a spare key.
