How to Replace a Jaguar XF Replacement Key Fob

Modern keyfobs that are high-tech aren't easily replaced. Unlike older metal keys, which can be copied at any hardware store for less than $5, the modern key fobs aren't easily replaced. Drivers will know when it's time to replace the battery if they see a decrease in the key fob's effectiveness range, as well as a "SMART KEY BATTERY LOW" message on their Jaguar vehicle's message center.

Keyless Entry

Keyless entry systems are becoming more popular with car buyers due to their ease of use and security features. For example, some models automatically lock or unlock when you touch the door handle, which is much simpler than having to search for keys in your bag or pocket. These locks are also more secure than standard locks, because 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 radio frequencies that carry a unique digital identification code that can only be recognized by the vehicle. When you press one of the buttons on the Jaguar key fob, it transmits the code to the car's computer, which in turn responds by unlocking the doors and kicking off the engine. The key fob also transmits signals to a receiver inside the trunk that can be used to open the tailgate without hands.

Unfortunately, thieves have discovered ways to evade these systems. They've been able utilize software to decode the signals transmitted by key fobs, or remotely reprogram a new key using the transponder code of your car. To prevent this, experts advise adding an enclosed protection case to your key fob. These cases limit the distance frequencies that the fob emits travel, and they are readily available at many auto parts stores for under $10.

Remote Start

Anti-Theft System

The anti-theft device is designed to stop criminals from absconding with Jaguars. It employs a special technology called Ultra Wideband (UWB) to detect the key fob signal and verify that it's genuine. This prevents so-called relay attacks, which can block the signal that is used to unlock or start the vehicle even when the key isn't in the ignition. The system has a Guardian Mode that reports if the vehicle is suddenly unlocked or started. Jaguar suggests activating 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 beginning.

Modern Jaguars like older models are equipped with advanced security features that require specialized equipment and tools to maintain. This includes diagnostic tools, such as scanners that can detect the anti theft control module's diagnostic trouble codes and verify the freeze and real-time data. Technicians will need to examine the voltages analog across the entire system. You can do this by connecting a multimeter to the anti-theft control module, or by using the factory software. This is generally the best way to diagnose the anti-theft system. If the technician discovers problems, they may need to replace the module.

Bluetooth

Bluetooth has been around since over 20 years, and has revolutionized wireless communication. The technology is everywhere, from lighting bulbs to cars and smartphones. Both devices need to be turned on, and positioned close to each other in order for communication to take place. You may need to go into your device's settings depending on the type. A iOS or Android phone has an Bluetooth menu, whereas desktop computers typically have one within the Control Panel.

The initial Bluetooth connection will have to be established, with the two devices exchanging unique addresses, which are represented as hexadecimal values. Bluetooth unlike other RF technologies is secure. It employs encryption and authentication to secure data transmissions. Bluetooth operates in the unlicensed ISM frequency band, and a standard set of guidelines and specifications differentiates Bluetooth from other protocols like ZigBee and WiFi.

InControl allows you to pair smartphones that are compatible with Jaguar XF models. This is accomplished through the phone's Bluetooth menu; the steps vary between manufacturers and therefore, you should consult the InControl manual to learn how to do it. You may also have to enter a passkey to complete the connection which will be shown on the vehicle's touchscreen.
