How to replace the PassLock sensor on a GM car?
Find the three wires that connect the Passlock Sensor to the Body Control Module and substitute our circuit for the Passlock Sensor. Perform the “Relearn” Procedure so that our Body Control Module recognizes our new circuit. Go to Radio Shack and buy a Mini Terminal Block, and a package of 2200 ohm (2.2k-Ohm) resistors.
How do I Turn Off the PassLock sensor?
•The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK. 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.
When did the Chevrolet PassLock system come out?
One of Chevrolet’s solutions for stopping thieves from driving away with a car is, coincidently, doing the same thing to the actual owner. Passlock is an immobilizer introduced by GM in many mid-to-late 1990’s vehicles.
How long to relearn PassLock sensor data code?
Turn OFF the ignition, and wait 5 seconds . Repeat steps 1 through 4, 2 more times for a total of 3 cycles/30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
What does the sensor do on a GMC Sierra?
A sensor tells the security system whether the key is in the ignition or not. This is a common feature in the GMC, Pontiac, Oldsmobile, Saturn, Chevrolet and other past and present GM brand vehicles. The wire, which is connected to that sensor, comes loose or corroded and needs to be secured or cleaned.
What are the problems with the GM PassLock system?
If you decide to bypass your Passlock system, please contact us with the outcome so that we can pass the information along. By far, the most common problem with the VATS system is broken wires in the steering column. These wires connect the ignition lock cylinder to the under-dash wire harness.

Where is the PassLock switch on a Chevy?
The switch allows the car’s passlock system to be switched on or off by splicing with a yellow wire that’s plugged into the cylinder lock. Once completed, the new switch should be placed underneath the dash right below the key hole.
