Keyless Entry

The convenience and security of keyless entry systems are becoming popular among car owners. For instance, certain models automatically lock or unlock when you touch the door handle, which is easier than fumbling with keys in your pocket or handbag. In addition, these locks tend to be more secure than standard car locks as they utilize rolling codes that are changed each time you use the key fob. This makes it much more difficult for thieves to smuggle or alter the signal.

Key fobs emit a radio frequency with an unique digital identity code that only the vehicle can recognize. When you press a button on a Jaguar's key fob the computer in the car receives the number and responds by unlocking doors and starting the motor. The key fob may also send a signal to the trunk receiver that can be used to open the tailgate without touching it.

Unfortunately, thieves are able to get around these systems. They've been able to use software that can decode the signals transmitted by key fobs, or remotely reprogram a new key with the transponder code of your car. In this regard, many experts recommend putting a shielded protection case to your key fob. These cases limit the distance frequencies generated by the fob travel. They are readily available at many auto parts stores for less than $10.

Remote Start

Your Jaguar XE keyfob can be used to remotely lock, unlock and start your vehicle. To activate the feature, press and hold the lock button while holding the key fob in the range of your vehicle.

This additional functionality comes at cost. The most recent key fobs are available only at dealerships and need to be programmed in your vehicle.

Anti-Theft System

The anti-theft system is designed to deter criminals from taking Jaguars. It employs a special technology called Ultra Wideband (UWB) to detect the key fob's signal and confirm that it is genuine. This prevents relay attacks, which can snoop on the signal to unlock or starting the car when keys aren't in ignition. The system also has Guardian Mode, which reports when the vehicle is locked or started unexpectedly. Jaguar recommends that you activate this feature during the handover process.

The Jaguar XF also features an immobilizer, which verifies that the key is used to start the engine. If the key is not being used the immobilizer will turn off the fuel pump, ignition coil and injectors, which will stop the car from getting started.

Modern Jaguars in contrast to older vehicles are equipped with sophisticated security systems that require specialized equipment and tools to service. Diagnostic tools, such as scanners are used to detect diagnostic trouble codes of anti-theft control modules and check real-time data and freeze frame. Technicians will also have to physically test the voltages of analog throughout the system. This can be accomplished by connecting a multimeter to the anti theft control module or by using the factory software. This is the most common method to determine the condition of the anti theft system. If the technician discovers a problem, they may require replacing the module.

Bluetooth

Bluetooth has been around for more than two decades and has revolutionized wireless communications. The technology is everywhere, from lights to cars and smartphones. To establish the Bluetooth connection between two devices, both need to be turned on and be close enough for the connection to occur. You may have to access your device's settings based on the type. An iOS or Android phone comes with a Bluetooth menu, while a desktop computer usually has one located in the Control Panel.

The initial Bluetooth connection will need to be established with the two devices exchanging unique addresses, which are presented as numbers in hexadecimal format. Bluetooth, unlike other RF technologies is secure. It employs encryption and authentication to ensure data transmissions. Bluetooth operates in the unlicensed ISM frequency band, and a uniform set of specifications and rules differentiates it from other protocols, such as ZigBee and WiFi.

The majority of Jaguar XF models offer Bluetooth connectivity as standard and it's possible to connect any compatible phone to the car via InControl. This is done using the phone's Bluetooth menu. The steps differ from one manufacturer to the next and models, so make sure to read the InControl manual to find out exactly how to accomplish it. It is possible that you will need to enter a passkey, which is displayed on the screen of your vehicle, in order to complete the connection.
