Keyless Entry

Keyless entry systems are becoming more and more popular with car buyers, thanks to their convenience and security features. For instance, certain models automatically lock or unlock when you press the door handle, which is much easier than fumbling with keys in your bag or pocket. These locks are also more secure than standard locks because they use rolling codes which change each time you use your key fob. This makes it harder for thieves to steal the signal or alter it.

Key fobs emit radio frequencies that carry a unique digital identification code that is only recognized by the vehicle. When you press a button on a key fob from Jaguar and the computer in the car detects the code and responds by unlocking doors and starting the motor. The key fob also sends a signal to a receiver in the trunk which can be used to open the tailgate hands-free.

Unfortunately, thieves have found ways to evade these systems. They've been able to use software that decodes the signals sent by the key fobs and even remotely reprograms keys to the car's security code. This is why many experts suggest adding an enclosed protection case to your key fob. These cases limit the distance at which frequencies generated by the fob travel, and they are readily available at many auto parts stores for under $10.

Remote Start

Your Jaguar XE keyfob can be used to remotely lock, unlock and start your vehicle. Press and hold the lock button while keeping the key fob within range of your car. Once the door handles are unlocked, push the start button to begin your engine. If the key fob can't be opened, the car will display the message "SMART Key Battery Low".

Anti-Theft System

The anti-theft system was designed to discourage criminals from stealing Jaguars. It makes use of a technology known as Ultra Wideband to detect and verify the signal of the key fob. This is to prevent relay attacks, which can interfere with the signal to unlock or start the vehicle even when the key is not in the ignition. The system has a Guardian Mode that reports if the vehicle is not locked or started. Jaguar suggests activating this feature during the handover procedure.

Additionally the Jaguar XF features an immobilizer that ensures that the key fob is being used to turn on the engine. If the key isn't being used the immobilizer will disable the fuel pump, ignition coil, and injectors, preventing the vehicle from starting.

Modern Jaguars, unlike older vehicles, have sophisticated security systems that require specialized equipment and tools to service. Diagnostic tools like a scanner can be used to read the diagnostic trouble codes of the anti-theft control modules and also check for real-time data and freeze frame. Technicians will need to test the analog voltages throughout the entire system. This can be done by connecting a multimeter to the anti theft control module or using the factory software. This is the most common method of identifying an anti-theft system. If the technician finds an issue, they might need to replace the module.

Bluetooth

To set up a Bluetooth connection between two devices, both have to be connected and be close enough for the communication to take place. You may have to access the device's settings, depending on the type of device: an iOS or Android phone will come with a Bluetooth menu; a desktop computer will usually have one within the Control Panel or the System Preferences.

The initial Bluetooth connection will have to be established, with the two devices exchanging their unique addresses that are the hexadecimal value. Bluetooth is, unlike other RF technologies is secure. It uses encryption and authentication to safeguard data transmissions. Bluetooth operates in the unlicensed ISM frequency band, and a standardized set of specifications and rules differentiates it from other protocols like ZigBee and WiFi.
