Provided is an on-board device comprising: a transmission processing unit (23) that causes a request signal to be transmitted; a reception processing unit (25) that receives a response signal which is a reply from a portable device (1) and which includes a code identifying the portable device; a comparison processing unit (26) that compares the code included in the response signal and a normal portable device code; a locking and unlocking control unit (28) for automatically causing a vehicle door to lock or unlock; a signal detection unit (21) that detects the signal of a locking and unlocking switch; and a debounce processing unit (24) that, on the basis of the signal of the locking and unlocking switch, carries out debounce processing for establishing the ON/OFF state of the locking and unlocking switch. The transmission processing unit causes the request signal to be sent if there was a fluctuation in the signal of the locking and unlocking switch. The locking and unlocking control unit automatically causes the locking or unlocking to be carried out if the comparison was concluded and the locking and unlocking switch ON/OFF state, which was established by completion of the debounce processing, is ON. |
