Keyless Entry

Keyless entry systems are becoming more and more popular with car owners due to their convenience and security features. For instance, certain models automatically lock or unlock when you press the door handle, which is easier than fumbling with keys in your bag or pocket. In addition, these systems tend to be more secure than standard car locks because they use rolling codes that change every time you use the key fob. This makes it difficult for thieves to hijack or spoof the signal.

Key fobs emit a radio frequency with an 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 kicking off the engine. The key fob also sends signals to a device in the trunk that can be used to open the tailgate without hands.

Unfortunately, thieves are finding ways around these systems. They have been able to make use of software that can decode the signals transmitted by key fobs or remotely reprogram a new key with the transponder code of your car. Many experts suggest the use of a shielded case for your keyfob. These cases limit the distance that radio frequencies from the fob can be transmitted. They are available at most auto parts stores and are priced less than $10.

Remote Start

Your Jaguar XE keyfob can be used to remotely lock or unlock your vehicle. Press and hold the lock button, while holding the key fob within reach of your vehicle. Push the start button once the door handles are locked. If the key fob is not able to be found, the vehicle will display the message "SMART KEY Battery Low".

This added functionality comes with a price. The most recent key fobs are only available from dealers and require programming to function in your vehicle.

Anti-Theft System

The anti theft system was designed to stop criminals from theft of your Jaguar. It makes use of a technology known as Ultra Wideband to detect and verify the signal of the key fob. This prevents so-called relay attacks that could interfere with the signal to unlock or start the vehicle even when the key is not in the ignition. The system comes with a Guardian Mode that reports if a vehicle is unlocked unexpectedly or started. Jaguar suggests activating this feature during the handover process.

Additionally to that, the Jaguar XF features an immobilizer that ensures that the key fob is being used to turn on the engine. The immobilizer shuts off the ignition coil, and injectors if the key fob isn't being used. This stops the vehicle from beginning.

Unlike older vehicles and vehicles, modern Jaguars come with advanced security systems that require specialized tools and equipment to maintain. Diagnostic tools, such as scanners can be used to identify the diagnostic trouble codes of the anti-theft modules and check real-time data and freeze frame. The technician will need to test analog voltages in the entire system. This can be done by connecting a multimeter to the anti theft control module or using factory software. This is the simplest method of diagnosing an anti-theft system. If the technician detects an issue, they could need to replace the system.

Bluetooth

Bluetooth has been around since over 20 years, and has revolutionized wireless communication. It is a common technology and can be found in everything from lighting bulbs to smartphones and automobiles. Both devices need to be on, and in close proximity to each other to allow communication to occur. You may have to access the settings of your device based on the type of device. A iOS or Android phone comes with an Bluetooth menu, while desktop computers usually have one in the Control Panel.

The initial Bluetooth connection will have to be established with the two devices exchanging unique addresses that are numbers in hexadecimal format. In contrast to other RF technologies, Bluetooth is secure, with encryption and authentication that protect data transmissions. It operates in the unlicensed ISM frequency band, and a standard set of rules and specifications differentiates Bluetooth from other protocols like ZigBee and WiFi.

Most Jaguar XF models offer Bluetooth connectivity as standard, and you can pair an compatible smartphone to the car through InControl. This is done using the smartphone's Bluetooth menu; the steps differ from one manufacturer to the next, so check the InControl manual to find out exactly what you need to do. You may also have to enter a passkey to complete the connection, which will be shown on your vehicle's touchscreen.
