Anti-Theft System

The anti-theft system was designed to discourage criminals from stealing Jaguars. It employs a technique called Ultra Wideband to detect and confirm the signal of the key fob. This is to prevent relay attacks which can intercept the signal for unlocking or starting the car when the key isn't in the ignition. The system also has Guardian Mode, which reports when the vehicle is not locked or started unexpectedly. Jaguar suggests activating this feature during the handover procedure.
