Keyless Entry

The convenience and security of keyless entry systems is gaining popularity among car buyers. For example, some models automatically lock or unlock when you touch the door handle, which is more convenient than fumbling for keys in your purse or pocket. These systems are more secure than standard locks because they utilize rolling codes that change each time you use your key fob. This makes it harder for thieves to steal the signal or alter it.

Key fobs emit a radio signal with a unique digital identification code that only the vehicle is able to recognize. When you press one of the buttons on a Jaguar key fob, it transmits this code to the car computer, which responds by opening the doors and starting the engine. Key fobs can also send a signal through the trunk receiver, which can be used for opening the tailgate without having to touch it.

However, criminals have discovered ways to circumvent these systems. They've managed to use software that decodes signals generated by the key fobs, or even remotely reprograms a new key to the car's code. Many experts recommend using a shielded cover for your key fob. These cases limit the distance that the frequencies generated by the fob are transmitted. They can be found in the majority of auto parts stores, and are priced less than $10.

Anti-Theft System

The anti-theft system was designed to stop criminals from taking Jaguars. It uses a unique technology known as Ultra Wideband (UWB) to detect the key fob signal and verify it's genuine. This helps prevent relay attacks, which can snoop on the signal used for unlocking or starting the car if the key isn't inserted in the ignition. The system also includes Guardian Mode, which reports that the vehicle has been locked or started unexpectedly. Jaguar recommends activating this feature during the handover process.

Additionally the Jaguar XF features an immobilizer that checks to see if the key fob is being used to start the engine. If the key is not being used, the immobilizer will disable the ignition coil, and injectors, preventing the vehicle from beginning.

Modern Jaguars like older models are equipped with advanced security features that require specialized equipment and tools to maintain. This includes diagnostic tools, such as scanners that detect the anti-theft control module's diagnostic trouble codes, and then check the freeze and real-time data. The technician will also need to physically test analog voltages throughout the system. This can be done by connecting a multimeter with the anti-theft control module or using the factory software. This is the most commonly used way to diagnose an anti-theft system. If the technician finds an issue, they could have to replace the module.
