Keyless Entry

The convenience and security of keyless entry systems is increasing in popularity with car buyers. For instance, certain models automatically lock or unlock when you touch the door handle, which is much simpler than having to search for keys in your pocket or handbag. These systems are also more secure than standard locks, as they use rolling codes which change every time you use your key fob.

Key fobs emit a radio frequency with a unique digital identity code that only the vehicle can recognize. When you press one of the buttons on a Jaguar key fob, it relays this code to the car computer, which in turn responds by unlocking the doors and starting the engine. Key fobs can also send a signal to the trunk receiver, which can be used for opening the tailgate without touching it.

Unfortunately, thieves are able to get around these systems. They have been able to employ software that decodes the signals transmitted by key fobs, or remotely reprogram a key using the transponder codes of the car. In this regard, experts advise adding an enclosed protection case to your key fob. These cases limit the distance at which the frequencies generated by the fob are transmitted. They are available at the majority of auto parts stores, and cost less than $10.

Anti-Theft System

The anti-theft system was designed to stop criminals from absconding with Jaguars. It employs a technique called Ultra Wideband to detect and verify the key fob's signal. This helps prevent relay attacks, which can snoop on the signal for unlocking or starting the car if the key isn't inserted in the ignition. The system also includes Guardian Mode, which reports if the vehicle is unlocked or started abruptly. Jaguar suggests that you turn on this feature during the handover process.

The Jaguar XF also features an immobilizer that confirms that the key is being used to start the engine. The immobilizer shuts off the fuel pump, ignition coil, and injectors when the key isn't used. This stops the car from being able to start.

Contrary to older models, modern Jaguars come with advanced security systems that require special tools and equipment for servicing. This includes diagnostic tools like scanners that can 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 to the anti-theft module or using the factory software. This is typically the best method to determine the condition of the anti-theft system. If the technician finds an issue, they might need to replace the device.
