What does it mean to have a PassLock on your car?
Temporary fixes are a pain in the butt, but permanent solutions can get quite expensive. Passlock is an immobilizer introduced by GM in many mid-to-late 1990’s vehicles. Immobilizers are “electronic security device fitted to an automobile that prevents the engine from running unless the correct key (or token) is present.”
How much of a value can a PassLock system accept?
You can be within about 5% of the value, and it will be accepted by the passlock system as genuine. Once you have assembled the resistors so they represent the correct value, tightly wrap one end of the resistor through and around the exposed copper of the black wire.
Is there a way to bypass PassLock 2?
The easiest way to bypass the Passlock 2 system is to place a resistor between the passlock sensing wire and the ground reference wire. To find these wires, look for three wires that at some point are wrapped together, coming from the ignition barrel. Usually, they are orange/black, red/white, and black.
When do you turn off the PassLock system?
The vehicle learns the Passlock Sensor Data Code and/or resistance on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 12. Your all done, Solder all your new connections.

Why did General Motors start the PassLock system?
Aug 1st, 2005 The PassLock system was designed to prevent vehicle theft by disabling fuel to the engine if attempts are made to start the vehicle without the correct bitted key. PASSLock increased the level of security while retaining the ease of service and costs offered by standard ignition lock systems.
