Keyless Entry

Keyless entry systems are becoming more and more popular with car buyers due to their ease of use and security features. Certain models lock or unlock the door when you touch it, which is much easier than searching for keys in your pocket. These locks are more secure than standard locks, as they use rolling codes that change each time you use your key fob. This makes it more difficult for thieves to hijack or alter the signal.

Key fobs emit a radio frequency with an unique digital identity code that only the vehicle can recognize. When you hit one of the buttons on the Jaguar key fob, it relays this code to the car computer, which responds by unlocking the doors and starting the engine. The key fob can also transmit a signal to the trunk receiver, which can be used to open the tailgate without having to open it.

Unfortunately, thieves have found ways to circumvent these systems. They have been able to make use of software that can decode the signals transmitted by key fobs, and even remotely reprogram a new key using the transponder code of your car. To prevent this, experts advise adding a shielded protection case to your key fob. These cases limit the distance that the frequencies that are emitted by the fob can be transmitted. They can be found in most auto parts stores and are priced less than $10.

Anti-Theft System

The anti theft system has been designed to deter criminals from theft of your Jaguar. It uses a technology called Ultra Wideband to detect and verify the signal of the key fob.
