1. Constitution of the Radio Frequency Keyless Entry System for vehicle T he radio frequenc y keyless entry is a system that it c ontrollers loc king and unloc king the door by wireless remote controller. This system consists of three components. The TRANS MITTER is a device that transmits the signal when the button is pressed. The transmission signal consists of several synchronous c odes, unique identification c ode , sec urity c ode and func tion c ode. The RE C E IVE R is fixed inside the vehicle.
2. Operation description REMOTE TRANSMITTE LOCK UNLOCK PANIC TRUNK You c an loc k and unloc k your vehicle with the remote transmitter. LOC K When you push the LOC K button, all the doors will lock.
