The key fob can also send a signal through the trunk receiver, which can be used for opening the tailgate without having to touch it.

Anti-Theft System

The anti-theft system is designed to discourage criminals from absconding with Jaguars. It makes use of a technology known as Ultra Wideband to detect and confirm the signal of the key fob.

Modern Jaguars unlike older vehicles, have sophisticated security systems that require specialized equipment and tools to service. Diagnostic tools such as scanners are used to identify the diagnostic trouble codes of the anti-theft modules and to check the real-time data as well as freeze frame. Technicians will need to test the analog voltages throughout the entire system. You can do this by connecting a multimeter to the anti-theft module or using the factory software.
