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 of three 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.
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.

5.Features 5.1 Door lock control The LOCK relay in the receiver drives the door lock actulators to "LOCK"-side when LOCK button of transmitter was pressed. The UNLOCK relay in the receiver drives 5.2 Battery saving To prevent the battery exhaustion , the micro-computer of the transmitter is usually inactive. When the button will be pressed, the micro-computer wakes up immediately and judges which button is pressing.
