Keyless Entry

Some models lock or unlock the door when you touch it, which is a lot easier than searching for keys in your pocket. Additionally, these systems tend to be more secure than standard car locks because they employ rolling codes that change each time you use the key fob. This makes it much more difficult for thieves to steal the signal or alter it.

Key fobs emit a radio frequency that has a unique digital identity number that only the vehicle can recognize. When you hit one of the buttons on a Jaguar key fob, it relays this code to the car's computer, which then responds by opening the doors and kicking off the engine. The key fob can also send a signal through the trunk receiver, which can be used for opening the tailgate without touching it.

They've been able to utilize software to decode the signals sent by key fobs, or remotely reprogram a new key with the transponder code for your car. Many experts suggest installing a shielded case on your keyfob. These cases limit the distance that frequencies generated by the fob could travel, and they are available at most auto parts stores for under $10.

Anti-Theft System

The anti theft system has been designed to stop criminals from getting your Jaguar. It utilizes a new technology called Ultra Wideband (UWB) to detect the key fob's signal and confirm that it is genuine. This is to prevent relay attacks which can snoop on the signal for unlocking or starting the vehicle when keys aren't in ignition. The system has a Guardian Mode that reports if the vehicle is locked unexpectedly or started. Jaguar recommends activating this feature during the handover process.

Additionally, the Jaguar XF features an immobilizer which checks that the key fob is used to turn on the engine. The immobilizer blocks the ignition coil, and injectors if the key isn't in use. This stops the car from starting.

Modern Jaguars in contrast to older vehicles are equipped with advanced security features that require specialized equipment and tools for servicing. Diagnostic tools such as scanners are used to read the diagnostic trouble codes of the anti-theft control systems and to check the real-time data as well as freeze frame. Technicians will need to test the analog voltages throughout the entire system. This can be accomplished by connecting a multimeter to 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 discovers an issue, they might have to replace the module.

Bluetooth

To set up a Bluetooth connection between two devices, both need to be turned on and be within a reasonable distance for the communication to take place. You may need to access the settings of the device, based on the type of device: an iOS or Android phone will come with a Bluetooth menu; a desktop computer will usually have a Bluetooth menu in the Control Panel or the System Preferences.

The initial Bluetooth connection will have to be paired with the two devices exchanging their unique addresses which are displayed as numbers in hexadecimal format. Contrary to other RF technologies, Bluetooth is secure, with encryption and authentication to secure data transmissions. Bluetooth operates in the unlicensed ISM frequency band, and a uniform set of specifications and rules distinguishes it from other protocols, such as ZigBee and WiFi.
