Technician A says the passive keyless entry (PKE) system consists of a fob transmitter and a receiver inside the vehicle. When a key or button is pressed,the receiver recognizes the key’s code and activates the vehicle’s electronic door locks. Technician B says the remote keyless entry (RKE) system consists of an electronic key that is carried on the person’s body. Once the electronic key is in close proximity to the vehicle,the vehicle unlocks the door without the need for any buttons or keys to be pressed. Who is correct?
