Keyless Entry
The convenience and security of keyless entry systems are growing in popularity with car owners. For instance, certain models automatically lock or unlock after you touch the door handle, which is easier than fumbling with keys in your pocket or handbag. These systems are more secure than standard locks, because they utilize rolling codes that change every time you use your key fob. This makes it harder for thieves to sabotage the signal or alter it.
Key fobs emit radio frequencies with a unique identification code that is only recognized by the vehicle. When you hit one of the buttons on a Jaguar key fob, it transmits the code to the car's computer, which then 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 to open the tailgate without touching it.
Unfortunately, thieves have discovered ways to get around these systems. They've managed to use software that decodes the signals sent by the key fobs, or even remotely reprograms a key to the car's number. Many experts suggest installing a shielded case on your key fob. These cases limit the distance that radio frequencies from the fob will travel. They are available in many auto parts stores and are priced less than $10.

Anti-Theft System
The anti-theft system is designed to stop criminals from taking your Jaguar. It utilizes a technology known as Ultra Wideband to detect and verify the signal from the key fob. This stops relay attacks that can block the signal that is used to unlock or start the car when the key is not in the ignition. The system also has Guardian Mode, which reports when the vehicle is not locked or started abruptly. Jaguar recommends activating this feature during the handover procedure.
The Jaguar XF also features an immobilizer that ensures that the key is being used to start the engine. If the key isn't being used the immobilizer will shut down the fuel pump, ignition coil and injectors, stopping your vehicle from getting started.
In contrast to older cars, modern Jaguars come with sophisticated security systems that require specialized tools and equipment for servicing. Diagnostic tools like scanners are used to identify the diagnostic trouble codes of anti-theft modules and to check the real-time data as well as freeze frame. The technician will need to test the analog voltages throughout the entire system. You can do this by connecting a multimeter with the anti-theft module or using the factory software. This is generally the best way to diagnose the anti-theft system. If the technician finds an issue, they might need to replace the module.
Bluetooth
Bluetooth has been in use for over 20 years, and has revolutionized wireless communication. Bluetooth technology is everywhere from lights to cars and smartphones. Both devices must be powered on, and positioned close to each other in order for communication to take place. You may need to go into the settings of the device, based on its type: an iOS or Android phone will include a Bluetooth menu and a desktop computer will usually have one in the Control Panel or the System Preferences.
The first Bluetooth connection is required. Both devices will exchange their unique addresses (which are displayed as hexadecimal numbers). In contrast to other RF technologies, Bluetooth is secure, with encryption and authentication to protect data transmissions. It operates on the unlicensed ISM band and is governed by a set of standard rules and specifications which distinguishes it from other protocols such as ZigBee or WiFi.
Most Jaguar XF models offer Bluetooth connectivity as standard and you can connect your compatible phone to the car through InControl. This is done using the phone's Bluetooth menu; the steps vary from manufacturer to manufacturer and therefore, you should consult the InControl manual to learn how to accomplish it. You may also need to enter a passcode to complete the connection, which will be shown on the vehicle's touchscreen.
