1. Constitution of the Radio Frequency Keyless Entry System for vehicle The radio frequency keyless entry is a system that it controls locking and unlocking the door and the trunk and the panic by wireless remote controller. This system consists ofthree components. The TRANSMITTER is a device that transmits the signal when the button is pressed. The transmission signal consists of several synchronous codes, unique identification code, security code and function code and crc code. The RECEIVER is fixed inside the vehicle. It works intermittently to prevent the battery exhaustion. Whenthe receiver detects the synchronous code, it runs continuously to receive the signals completely. After receiving thesignal, the receiver decides which operation will be performed. The user can select the following operations by pressing thebutton of the remote transmitter. OPERATIONACTION LOCK lock the door UNLOCKunlock the door TRUNKopen the trunk PANICalarm the horn Transmitter f = 313.85MHz -1- 2. User's manual (provisionally) REMOTE TRANSMITTER You can lock and unlock your vehicle with the remote transmitter. LOCK When you push the LOCK button, all the doors will lock. You cannot lock any of the doors with the remote transmitter if any door is open or the key is the ignition switch. UNLOCK When you push the UNLOCK button, all the doors will unlock. You cannot unlock any of the doors with the remote transmitter if any door isopen or the key is in the ignition switch. TRUNK When you push continuously the TRUNK button during 0.5s, TRUNK will open. PANIC When you push continuously the PANIC button during 0.5s, horn will alarm. -2- 3.

The transmission frame consists of the synchronous frame and the data frame. The synchronous frame has 320bit synchronous codes that it will be used for the receiver to wake up. The data frame consists of 24bit length identification code, 16bit security code and 4bit function code and 8bit crc code. 16million different identification codes are available. The security code is always changed in case of any of the buttons is pressed.Thetransmissiontimeistypically 300 milliseconds. 5.2 Battery saving To prevent the battery exhaustion , the micro-computer of the transmitteris usually inactive. When the button will be pressed, the micro-computer wakes up immediately and judges whichbutton is pressing. Then the micro-computer constructs the transmission frame and radiates it from the antenna .After transmitting, the micro-computer switches stand-by mode by itself. -5-
