Constitution of the Radio Frequency Keyless Entry System with Door Lock Controller for vehicle The radio frequency keyless entry is a system that it controls locking and unlocking the door by wireless remote controller. This system consists of two 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, and security code and function code. The RECEIVER is fixed inside the vehicle. It works intermittently to prevent the battery exhaustion. When the receiver detects the synchronous code, it runs continuously to receive the signals completely. After receiving the signal, the receiver decides which operation will be performed. The user can select the following operations by pressing the button of the remote transmitter. OPERATION LOCK UNLOCK PANIC MODE ACTION Lock the door Unlock the door (the driver side first, then all doors) Flush the light, flush the small light, and beep the horn. (it continues 30 seconds) This receiver also controls wired operation. When the key is in the driver’s side key cylinder, all doors will Unlock if the key is turned to UNLOCK and hold more than one second. In case of the operation time is shorter, the only driver’s side door is mechanically unlocked. It is also available to control the door lock status by using the remote door control switch (both driver’s and passenger’s side). Transmitter f =315.1MHz -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 in the ignition switch. UNLOCK When you push the UNLOCK button once , only the driver’s door unlocks. The remaining door unlock when you push the button a second time. If you unlock the doors with the remote transmitter, but do not open any of the doors within 30 seconds, the doors will automatically relocked. You cannot unlock any of the doors with the remote transmitter if the key is in the ignition switch. PANIC MODE Panic mode allows you to remotely sound your vehicle’s horn to attract attention. To activate this mode , press and hold the PANIC button for about one seconds. Your vehicle’s horn will beep for about 30 seconds. To cancel Panic mode before 30 seconds , press any button on the remote transmitter. You can also turn the ignition switch is in ON. -2- 3.

Features 5.1 Transmission frame The transmission begins immediately in case of LOCK or UNLOCK button is pressed. The transmission frame consists of the synchronous frame and the data frame. The synchronous frame has 81 synchronous codes that it will be used for the receiver to wake up. The data frame consists of 28-bit length identification code, 16-bit security code and function code. 1600 million different identification codes are available. The security code is always changed in case of any of the buttons is pressed. The transmission time is typically 370 milliseconds. 5.2 Battery saving To prevent the battery exhaustion, the microcomputer of the transmitter is usually inactive. When the button will be pressed, the microcomputer wakes up immediately and judges which button is pressing. Then the microcomputer constructs the transmission frame and radiates it from the antenna. After transmitting, the microcomputer switches stand-by mode by itself. -5- 6.
