Keyless Entry

Some models lock or unlock the door when you touch it, which is easier than trying to find keys in your pockets.

When you hit one of the buttons on a Jaguar key fob, it transmits this code to the car's computer, which in turn responds by opening the doors as well as starting the engine. The key fob also sends signals to a receiver inside the trunk that can be used to open the tailgate without hands.

Unfortunately, thieves have discovered ways to bypass these systems. They have been able to employ software that decodes the signals transmitted by key fobs, and even remotely reprogram a new key using the transponder codes of the car. For this reason, many experts suggest adding an enclosure that is shielded to protect your key fob. These cases limit the distance at which frequencies generated by the fob travel. They can be found at most auto parts stores for under $10.
