The convenience and security of keyless entry systems is growing in popularity with car owners. For instance, certain models automatically lock or unlock when you press the door handle, which is more convenient than fumbling for keys in your purse or pocket. In addition, these systems tend to be more secure than standard car locks due to the fact that they employ rolling codes that are changed each time you use the key fob.

When you press one of the buttons on the Jaguar key fob, it transmits this code to the car computer, which in turn responds by opening the doors and then starting the engine.

Anti-Theft System
The anti-theft system is designed to discourage criminals from taking Jaguars. It employs a technique called Ultra Wideband to detect and verify the key fob's signal.
