How to Replace a Jaguar XF Replacement Key Fob

Keyfobs with the latest technology are not easily replaceable. Unlike older metal keys that can be copied at any hardware store for less than $5, the modern key fobs cannot be easily replaced.

Keyless Entry

The convenience and security of keyless entry systems are becoming popular among car owners. For example, some models automatically lock or unlock when you tap the door handle, which is much more convenient than fumbling for keys in your purse or pocket.

Key fobs emit radio frequency with a unique, digital identification code that can only be recognized by the vehicle. When you press one of the buttons on a Jaguar key fob, it transmits the code to the car's computer, which in turn responds by unlocking the doors and starting the engine. The key fob can transmit 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 reprograms a key to the car's code. Many experts suggest installing a shielded case on your keyfob. These cases limit the distance the frequencies that are emitted by the fob will travel. They are available in many auto parts stores and cost less than $10.

Anti-Theft System

The anti-theft system is designed to deter criminals from taking your Jaguar. It makes use of a technology known as Ultra Wideband to detect and verify the signal of the key fob.

This includes diagnostic tools such as scanners that can detect the anti theft control module's diagnostic trouble codes and also check real-time and freeze frame information.
