<p>PURPOSE:To prevent elimination of stored data resulting from misoperation by repeating operation of a door switch more than a predetermined number of times so that a rewriting device for changing the identification code of a door lock device operated by a remote control device is held in a rewritable state, and performing rewriting operation thereafter. CONSTITUTION:Should a transmitter 1 be lost or damaged, a rewriting device 11 used in changing an identification code 9 stored is held in a rewritable state by detecting that operation of a door switch 13 is repeated more than a specific number or times. Next, a signal newly output from the transmitter 1 is stored in a storage device 9 and the identification code is rewritten. Rewritting is carried out without replacing components constituting the storage device. Elimination of stored data due to misoperation can thus be prevented.</p> |
