Abstract
A keyless entry system includes a portable transmitter that transmits a lock signal and an unlock signal, each of which contains a unique identification code, for a predetermined period, and an operation unit that locks and unlocks doors of a vehicle in response to the lock signal and the unlock signal from the portable transmitter. The operation unit includes a receiver that outputs a lock command signal or an unlock command signal having a predetermined time length, and a controller that drives an actuator to lock or unlock the doors of the vehicle in response to the lock command signal or the unlock command signal from the receiver. The time length of the unlock command signal from the receiver is shorter than the time length of the unlock signal from the portable transmitter.
