How to Replace a Jaguar XF Replacement Key Fob

Modern keyfobs that are high-tech cannot be replaced easily. Contrary to the older metal keys which can be purchased at any hardware store for less than $5, the modern key fobs can't be easily replaced. The battery must be replaced if the range of the key fob decreases and the Jaguar vehicle's message center shows the message "SMART KEY" The battery is low.


Keyless Entry

The convenience and security of keyless entry systems is becoming popular among car owners. Certain models lock or unlock the door when you touch it, which is a lot easier than searching for keys in your pocket. These locks are more secure than standard locks, as they use rolling codes which change every time you use your key fob. This makes it more difficult for thieves to steal or alter the signal.

Key fobs emit a radio frequency, which has a unique digital identity number that only the vehicle can recognize. When you press a button on the Jaguar's key fob, the computer in the car receives the number and responds by opening doors and triggering the motor. The key fob also transmits signals to a device inside the trunk that can be used to open the tailgate hands-free.

Unfortunately, thieves have found ways to evade these systems. They've used software that decodes the signals transmitted by key fobs or even remotely reprograms a new key to the car's security code. In this regard, experts advise adding a shielded protection case to your key fob. These cases limit the distance at which the frequencies generated by the fob will travel. They are available at the majority of auto parts stores and cost less than $10.

Remote Start

Press the start button after the door handles are locked. If the fob for your key cannot be opened, the car will display the message "SMART Key Battery Low".

The added convenience comes at costs. The most recent key fobs can only be purchased from dealers and require programming to function inside your vehicle.

Anti-Theft System

The anti-theft system was created to deter criminals from taking Jaguars. It utilizes a unique technology known as Ultra Wideband (UWB) to detect the key fob signal and confirm it's authentic. This prevents so-called relay attacks that could intercept the signal to unlock or start the car when the key isn't in the ignition. The system also features Guardian Mode, which reports when the vehicle is not locked or started in a sudden manner. Jaguar recommends that you activate this feature as part of the handover process.

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

As opposed to older vehicles that were built in the past, modern Jaguars have sophisticated security systems that require specialized tools and equipment to service. This includes diagnostic tools, such as a scanner that can read the anti-theft control module's diagnostic trouble codes and check real-time and freeze frame information. The technician 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 usually the best way to diagnose the anti-theft system. If the technician spots an issue, they may require replacing the module.

Bluetooth

Bluetooth has been around since more than 20 years ago and has revolutionized wireless communication. Bluetooth technology is everywhere from lighting bulbs to cars and even smartphones. Both devices must be turned on and placed close to each other for communication to occur. You may have to go into the settings of your device, based on the model: an iOS or Android phone will include a Bluetooth menu for desktop computers; while a smartphone will usually have one within the Control Panel or System Preferences.

The initial Bluetooth connection will need to be paired with both devices exchanging unique addresses, which are presented as the hexadecimal value. Unlike other RF technologies, Bluetooth is secure, with encryption and authentication to safeguard data transmissions. Bluetooth operates on the unlicensed ISM band and has a set of standard rules and specifications which distinguishes it from other protocols like ZigBee or WiFi.

Most Jaguar XF models offer Bluetooth connectivity by default and it's possible to connect an compatible smartphone to the car via InControl. This is done using the smartphone's Bluetooth menu. The steps differ between different manufacturers and therefore, you should consult the InControl manual to know exactly what you need to do.
