Oldsmobile – VATS System, Keys and Programming Solutions in Puerto Rico | Certified Locksmith
What is the VATS system in Oldsmobile vehicles?
Oldsmobile vehicles use the VATS (Vehicle Anti-Theft System) , one of the first electronic anti-theft systems. As a Certified Locksmith in Puerto Rico , I know this system works differently than modern transponders.
Key with resistor (visible chip)
The key has a metal pellet that contains a specific resistance.
Vehicle resistance reading
The car measures that resistance when the key is inserted; if it doesn't match, it blocks the ignition.
Common problems in VATS systems (very important 🔥)
The car won't start even though the key turns.
The system does not recognize the correct resistance and activates the lock.
Wear on the key or contacts
The pellet may wear out or the contacts inside the cylinder may fail.
VATS module failure
The system may stop reading correctly even with the original key.
Typical symptoms of VATS failure
Safety light on or flashing
It indicates that the system does not validate the key.
The car doesn't "crank" or doesn't start
The system completely blocks the ignition.

It is an electrical resistance system, and requires a different diagnosis.

Frequently Asked Questions about VATS
Can a VATS key be programmed?
