Keyless Entry

Keyless entry systems are becoming more popular with car owners because of their convenience and security features.

Key fobs emit radio frequency with a unique, digital identification code that can only be recognized by the vehicle. When you press the button on a key fob of a Jaguar the computer in the car receives the code and responds by opening doors and starting the motor. Key fobs can also send a signal to a trunk receiver that can be used to open the tailgate without having to open it.

Anti-Theft System

The anti-theft system was designed to discourage criminals from stealing Jaguars. It employs a special technology called Ultra Wideband (UWB) to detect the key fob's signal and confirm it's authentic. This is to prevent relay attacks which can snoop on the signal for unlocking or starting the vehicle when keys aren't in ignition. The system comes with a Guardian Mode that reports if the vehicle is suddenly unlocked or started. Jaguar recommends activating this feature during the handover process.
