When you hit one of the buttons on a Jaguar key fob, it sends this code to the car computer, which in turn responds by opening the doors as well as starting the engine. The key fob may also transmit a signal to the trunk receiver that can be used for opening the tailgate without having to open it.

Unfortunately, thieves are able to bypass these systems. They have been able use software that decodes the signals sent by the key fobs and even remotely reprograms a key to the car's number. For this reason, experts advise adding an enclosure that is shielded to protect your key fob.

Anti-Theft System

The anti theft system is designed to deter criminals from taking your Jaguar. It uses a unique technology known as Ultra Wideband (UWB) to detect the key fob signal and verify that it's genuine. This blocks relay attacks which could interfere with the signal to unlock or start the car when the key isn't in the ignition.

Modern Jaguars like older models are equipped with sophisticated security systems which require special equipment and tools to service. Diagnostic tools, such as a scanner can be used to identify the diagnostic trouble codes of anti-theft control systems and check real-time data and freeze frame.

This is usually the best method to identify the anti theft system. If the technician discovers any issue, they could require replacing the module.
