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 disables the fuel system unless a properly coded key is inserted into the ignition cylinder. To integrate 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 systems 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, VATS/PASSLOCK bypass module must be installed. The Passkey 3 system, which is found on GM vehicles 1999 and newer, is a transponder based system described below. interface into transponder systems, a transponder bypass module must be installed. These modules allow full functionality of the factory anti-theft system and usually require the use of a spare key. ADDING TRANSMITTERS To add a new transmitter to the system have the desired transmitters ready and follow the Code Learning sequence. To enter Code Learning Mode: 1. Turn the ignition on, off, on, off and leave on. • The siren will chirp. 2. Press the Override switch. • The status LED will turn on red. • The siren will chirp. 3. Press the Lock Button on the transmitter. • The siren will chirp. 4. Repeat step 3 for each additional transmitter, up to four total transmitters. 5. Turn off the ignition. • The siren will chirp 3 times. NOTE: If a transmitter is lost or stolen, make sure to code all 4 transmitter memory locations. (Example: If only one transmitter is used, repeat step 3 three more times to remove any previously programmed transmitters.) 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 disabled, not allowing the vehicle to run, if the transponder is not detected. To properly 20
