1.
Constitution of the Radio Frequency Keyless Entry
System for vehicle
The radio frequency keyless entry is a system that it controllers 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.
OPERATION

TRUNK
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 t h e
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 is open or the key is i n
the ignition switch.
TRUNK
When you push continuously the TRUNK button during 0.5s, TRUNK will open.
PANIC
When you push the PANIC button, Siren will alarm.

5. Features
5.1 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 t o
"UNLOCK"-side when UNLOCK button of transmitter was pressed.
These facility doesn't work if the key is inserted the key clinder or the door is open.
5.2 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.
6. Derivatives
OKA-351R 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.
