How to Replace a Jaguar XF Replacement Key Fob

Contrary to older keys made of metal that can be copied for less than $5 at any hardware store, today's high-tech key fobs cannot be replaced easily. Drivers will be aware that it's time to replace the battery when they notice a reduction in the effective range and 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 because of their convenience and security features. For instance, certain models automatically lock or unlock after you touch the door handle, which is much less trouble than fumbling around with keys in your pocket or handbag. Additionally, these systems tend to be more secure than standard car locks because they use rolling codes that change each time you use the key fob. This makes it much more difficult for thieves to steal the signal or alter the signal.

Key fobs emit radio frequency that carry a unique digital identification code that is only recognized by the vehicle. When you press the button on a key fob from Jaguar the computer inside the car receives the code and responds by opening doors and triggering the motor. The key fob may also send a signal to the trunk receiver that can be used for opening the tailgate, without having to touch it.

However, criminals have discovered ways to bypass these systems. They've been able to use software that can decode the signals transmitted by key fobs, or even remotely reprogram a key using the transponder code of your car. Many experts recommend using a shielded cover for your key fob. These cases limit the distance at which the frequencies emitted from the fob can be transmitted. They are available at most auto parts stores and cost less than $10.

Remote Start

You can use your Jaguar XE key fob to lock, unlock and start your vehicle remotely. To activate the feature simply press and hold the lock button while securing your key fob within reach of your vehicle. After the door handles have been not locked, press the start button to begin your engine. If the key fob isn't within range the car will display the "SMART KEY BATTERY LOW" message.

However, that extra function is a cost: the latest key fobs are required to be purchased from the dealer and programmed with your vehicle.

Anti-Theft System

The anti-theft system has been designed to discourage criminals from taking Jaguars. It uses a technology called Ultra Wideband to detect and verify the signal of the key fob. This is to prevent relay attacks that could intercept the signal to unlock or start the car when the key isn't in the ignition. The system also includes Guardian Mode, which reports that the vehicle has been locked or started abruptly. jaguar key programming recommends activating this feature during the handover procedure.

The Jaguar XF also features an immobilizer that ensures that the key is being used to start the engine. If the key isn't being used the immobilizer will disable the fuel pump, ignition coil and injectors, which will stop your car from beginning.

Unlike older vehicles, modern Jaguars have sophisticated security systems that require specialized tools and equipment to maintain. Diagnostic tools such as a scanner can be used to detect diagnostic trouble codes of anti-theft control systems and check real-time data and freeze frame. The technician also needs to physically test the voltages of analog throughout the system. This can be done by connecting a multimeter with the anti-theft control system or using the factory software. This is the most popular method to identify an anti-theft system. If the technician finds problems, they may require replacing the module.

Bluetooth

Bluetooth has been around since more than 20 years and has revolutionized wireless communication. The technology is everywhere and can be found in everything from lighting bulbs to smartphones and cars. To establish a Bluetooth connection between two devices, both need to be turned on and be in close proximity for the connection to occur. You may need to go into your device's settings based on the model. A iOS or Android phone has an Bluetooth menu, while desktop computers usually have one within the Control Panel.

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

InControl allows you to pair an compatible smartphone to most jaguar keys XF models. The steps to pair your phone to the car differ based on the manufacturer, so make sure you read the InControl manual for the precise steps.
