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 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. 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.

4.Features
4.1 Door Lock Control
The LOCK relay in the receiver drives the door lock actuators to “LOCK”-side when LOCK button of
transmitter was pressed. The UNLOCK relay in the receiver drives the door lock actuators to
“UNLOCK”-side when UNLOCK button of transmitter was pressed. These facility doesn’t work if the key
is inserted the key cylinder or door is open
4.2 Battery saving
Because of the power source of the receiver is car Battery, it is very important problem to minimize a power
consumption. The receiver’s CPU works intermittently to prevent the battery exhaustion.
5. Derivatives
OKA-110R is an integrated controller for a car body control, includes the keyless entry receiver.
The integrated controller consists of the multiple control functions as follows, centralized door lock,
turn-signal lamp, room-lamp, intermitted wiper, power window timer, ignition key illumination, warning
buzzer and so on.
