<p>PROBLEM TO BE SOLVED: To provide a keyless entry system, by which a mean consumption power in an intermittent reception system can be reduced. SOLUTION: The keyless entry system has a transmitter 20 transmitting a binary-coding pulse signal D containing at least start bits and a proper identification code by the operation of a user, a receiver 10 receiving the signal D from the transmitter 20, and a control section 11 outputting an output signal for, conducting desired operation intended by the user when the identification code received by the receiver 10 and a registered code stored in a storage section 14 are decided and both codes coincide. A reception section 12 brought to the power-supply state capable of receiving the signal D at every fixed time, brought to the power-supply state capable of receiving at least the identification code when the continuous reception of partial bits in a plurality of bits constituting the start bits under the power-supply supply state is determined by the control section 11 and brought to the power-supply interrupting state when no continuous reception of the partial bits of a plurality of the bits constituting the start bits is determined by the control section 11 is mounted on the receiver 10.</p> |
