How to Replace a Jaguar XF Replacement Key Fob

Keyfobs with the latest technology are not easily replaceable. Unlike older metal keys which can be purchased at any hardware store for less than $5, the modern keys cannot be easily replaced. The battery must be replaced when the key fob’s range decreases and the jaguar key fob vehicle's message center displays the message "SMART KEY" The battery is low.

Keyless Entry

The convenience and security of keyless entry systems are growing in popularity with car owners. For example, some models automatically lock or unlock when you tap the door handle, which is much easier than fumbling with keys in your bag or pocket. These locks are more secure than standard locks, as they use rolling codes which change each time you use your key fob. This makes it harder for thieves to hijack the signal or alter it.

Key fobs emit a radio signal with a unique digital identification code that only the vehicle is able to recognize. When you press a button on a Jaguar's key fob the computer in the car receives the number and responds by opening doors and triggering the motor. The key fob can also send a signal through the trunk receiver, which can be used for opening the tailgate, without having to touch it.

However, criminals have discovered ways to evade these systems. They've been able utilize software to decode the signals transmitted by key fobs, and even remotely reprogram keys using the transponder code of your car. In this regard, many experts recommend putting an enclosure that is shielded to protect your key fob. These cases limit the distance at which frequencies that the fob emits 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 or unlock your vehicle. Press and hold the lock button, while keeping the key fob within reach of your car. After the door handles have been unlocked, press the start button to start the engine. If the key fob isn't within range, the car will display the "SMART KEY BATTERY LOW" message.

All new Jaguar models are equipped with remote-starting capability. This feature allows you to start your car from your smartphone. This feature is particularly useful when you're returning home from a long drive or when it's too cold to turn on the heater.

However, this extra functionality comes at a price: the latest key fobs should be purchased from the dealership and programmed to work with your vehicle.

Anti-Theft System

The anti theft system was designed to stop criminals from stealing your jaguar keys. It utilizes a unique technology known as Ultra Wideband (UWB) to detect the key fob signal and verify it's genuine. This prevents so-called relay attacks that could intercept the signal to unlock or start the vehicle even when the key is not in the ignition. The system includes a Guardian Mode that reports if the vehicle is locked unexpectedly or started. Jaguar recommends activating this feature as part of the handover process.

The Jaguar XF also features an immobilizer, which verifies that the key is being used to start the engine. If the key is not being used the immobilizer will disable the fuel pump, ignition coil, and injectors, preventing the car from starting.

Contrary to older models that were built in the past, modern Jaguars come with sophisticated security systems that require special tools and equipment in order to service. This includes diagnostic tools, such as scanners that read the anti theft control module's diagnostic trouble codes and check real-time and freeze frame data. 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 the most common method to identify the anti-theft system. If the technician detects an issue, they could have to replace the module.

Bluetooth

Bluetooth has been in use for more than two decades and has revolutionized wireless communications. Bluetooth technology is everywhere from lights to cars and even smartphones. Both devices must be turned on, and positioned close to each other in order for communication to occur. You may have to access the settings of your device, based on the model: an iOS or Android phone will come with a Bluetooth menu for desktop computers; while a smartphone will usually have a Bluetooth menu in the Control Panel or System Preferences.

The initial Bluetooth connection must be paired with both devices exchanging their unique addresses that are hexadecimal values. Bluetooth unlike other RF technologies is secure. It uses encryption and authentication to protect data transmissions. It operates on the unlicensed ISM band and comes with a set of standard rules and specifications that distinguishes it from other protocols, such as ZigBee or WiFi.

Most Jaguar XF models offer Bluetooth connectivity as standard and it's possible to connect any compatible phone to the car through InControl. The steps to pair your phone with the car will vary based on the manufacturer, so make sure you read the InControl manual for exact steps. You may be required to enter a passkey, which is displayed on the touchscreen of your vehicle, to complete the connection.
