All you have to do is place the key fob in close proximity to the car's reader. There RFID reader's location is marked on the steering wheel for your convenience. Just hold the key fob next to the reader and depress the start button. The RFID value is read and compared in a similar manner as an actual transmission. However, it may lack some level of full encryption used in a transmitting environment. This does not mean there is no encryption. It just may be less than that used by the transmitter.
