How does Proximity Key Fobs Operate?

Proximity Key Fobs allows the user of car to lock, unlock and start the vehicle without the requirement of the car keys. Proximity key fobs are recognized by the antenna embedded in the car and communicate with the antenna through the radio waves signals. And when the proximity key comes nearby the car, the car doors automatically lock and unlock with mere touch on the car handle. Vehicles equipped with proximity or smart key fobs can unlock the immobilizer and start the car without placing a key in the ignition. However the basic requirement for such ignition is that the proximity key fobs should be inside the vehicle. And for security reasons proximity key fobs transmit different frequency signals and antenna embedded inside the vehicle received the signals and prompt new frequency to be created.
