Keyless Entry
Keyless entry systems are becoming more and more popular with car buyers, thanks to their convenience and security features. Some models lock or unlock the door when you make contact with it, which is easier than trying to locate keys in your pockets. These systems are more secure than standard locks as they use rolling codes which change every time you use your key fob. This makes it difficult for thieves to steal or spoof the signal.
Key fobs emit a radio frequency that has a unique digital identification code that only the vehicle can recognize. When you press one of the buttons on a Jaguar key fob, it transmits the code to the car's computer, which then responds by unlocking the doors and then starting the engine. The key fob can also transmit a signal to the trunk receiver, which can be used for opening the tailgate without having to open it.
Unfortunately, thieves are able to bypass these systems. They've managed to use software that decodes the signals transmitted by key fobs, or even remotely reprograms keys to the car's security code. Many experts recommend using a shielded cover for your keyfob. These cases limit the distance that frequencies generated by the fob could travel, and they are available at a majority of auto parts stores for less than $10.

Anti-Theft System
The anti-theft system is designed to discourage criminals from taking Jaguars. It utilizes a technology known as Ultra Wideband to detect and verify the signal from the key fob. This helps prevent relay attacks, that could intercept the signal used for unlocking or starting the vehicle when the key isn't inserted in the ignition. The system has a Guardian Mode that reports if a vehicle is unlocked unexpectedly or started. Jaguar recommends activating this feature during the handover process.
The Jaguar XF also features an immobilizer that ensures that the key is used to start the engine. The immobilizer shuts off the fuel pump, ignition coil, and injectors when the key isn't being used. This stops the vehicle from being able to start.
In contrast to older cars that were built in the past, modern Jaguars have sophisticated security systems that require specialized tools and equipment to maintain. Diagnostic tools, such as scanners are used to read the diagnostic trouble codes of the anti-theft modules and to check the real-time data as well as freeze frame. The technician will need to examine the voltages analog across the entire system. You can do this by connecting a multimeter with the anti-theft control module or using the factory software. This is the most popular method to identify an anti-theft system. If the technician detects an issue, they could need to replace the device.
Bluetooth
