Keyless Entry

Keyless entry systems are becoming more popular with car owners, thanks to their convenience and security features. Certain models lock or unlock the door when you touch it, which is a lot easier than trying to locate keys in your pockets. In addition, these systems tend to be more secure than standard car locks due to the fact that they employ rolling codes that change every time you use the key fob. This makes it much more difficult for thieves to steal the signal or spoof the signal.

Key fobs emit a radio frequency, which has a unique digital identification code that only the vehicle is able to recognize. When you press a button on a key fob of a Jaguar and the computer in the car receives the number and responds by opening doors and triggering the motor. The key fob also transmits a signal to a receiver in the trunk that can be used to open the tailgate without hands.

Unfortunately, thieves have found ways to circumvent these systems. They've been able to use software that decodes signals sent by key fobs or even remotely reprograms a key to the car's code. Many experts suggest adding a shielded case to your key fob. These cases limit the distance that frequencies emitted by the fob can travel. They are readily available at many auto parts stores for under $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 confirm the signal of the key fob. This blocks relay attacks which could block the signal that is used to unlock or start the car when the key is not in the ignition. The system has a Guardian Mode that reports if a vehicle is unlocked unexpectedly or started. Jaguar recommends activating this feature during the handover process.

Modern Jaguars, unlike older vehicles are equipped with sophisticated security systems which require special equipment and tools to service. Diagnostic tools, such as scanners can be used to read the diagnostic trouble codes of anti theft control modules and check real-time data and freeze frame.

This is the most common method of identifying the anti theft system. If the technician finds an issue, they might need to replace the device.
