Keyless Entry

The convenience and security of keyless entry systems is increasing in popularity with car buyers. Some models lock or unlock the door when you make contact with it, which is a lot easier than searching for keys in your pockets. In addition, these locks tend to be more secure than standard car locks since they use rolling codes that alter each time you use the key fob. This makes it difficult for thieves to hijack the signal or spoof it.

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

Anti-Theft System

The anti-theft system was designed to deter criminals from absconding with Jaguars. It employs a special technology known as Ultra Wideband (UWB) to detect the key fob signal and confirm that it is genuine. This stops relay attacks that could intercept the signal to unlock or start the car even when the key is not in the ignition. The system includes a Guardian Mode that reports if the vehicle is suddenly unlocked or started. Jaguar suggests activating this feature during the handover procedure.
