VATS/PASS Keys Part 2: Ignition Lock Repair & Replacement

15 Sep VATS/PASS Keys Part 2: Ignition Lock Repair & Replacement

Unless you’re driving a classic or a Formula One car, chances are your vehicle has some sort of anti-theft system. If it’s a GM car made between 1986 and 2003, it may have a VATS or PASS ignition. These acronyms stand for Vehicle Anti-Theft System and Personal Automotive Security System.

When your anti-theft system breaks down, it’s almost always you who is inconvenienced the most.

If your key fails, you’ll have to get a duplicate or replacement key. But what if the problem isn’t with the key?

System Failure

The most common cause of system failure is broken or loose wiring in the steering column that connects the ignition lock to the under-dash wiring harness. Chances are your VATS/PASS system will let you know if it’s ready to fail. If the system detects a fault, you should see a warning light or message on the Driver Information Center (DIC). If it comes on while you’re driving, count yourself lucky…kind of. At least you can get to a repair center before you turn the car off, because chances are once it’s off, you may not be able to start your car again until the system is fixed.

Fixing the Broken or Loose Wiring

Fixing it is a matter of replacing the ignition lock cylinder, which comes with a new set of wires that run through the steering column to the main harness. It’s a job best left to someone experienced with vehicle wiring.

Programming a New Key

The new cylinder comes with a key that will operate the cylinder, but won’t start the car. That’s because it doesn’t have a programmable resistor to match the car’s control module settings, which can’t be changed after its initial use. You could replace the control module, but that’s not necessary and is expensive. The solution is to make a new key with a resistor chip embedded and then program the key to work with your controller. Dealers and locksmiths with the proper equipment can get the code from your old key with a device called an interrogator and program the new one to work. If the key is lost, it gets more complicated, but not hopeless. Part One explains the process.
