Passive Anti-Theft System (PATS) - Overview: Overview
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The PATS deters the vehicle from theft by preventing the vehicle from starting unless a valid programmed key is detected inside the vehicle when the START/STOP button is pressed.
PATS does not disable a vehicle that is already running.
