VATS keys are essentially the first electronic keys and, as such, provide a much-needed improvement in vehicle safety from their predecessors. VATS keys have resistors embedded in them, and when someone inserts a VATS key into the ignition of their vehicle, an electrical current runs through the resistor inside.

How does the GM VATS system work?

VATS is a General Motors (GM) security system that has a resistor embedded in the blade of the key. ... The sensor then sends a signal to the control, which GM has moved several times over the model years. The control then sends the code to the PCM. If the code is correct, the PCM will allow the car to start and run.
