PURPOSE:To obtain a remote control key providing time information in good accuracy by outputting key code time information from the first microcomputer during at least the remote control operation of unlocking the remote control door. CONSTITUTION:The positive electrode of a battery 11 is connected to a first microcomputer 12 and the negative electrode of the battery 11 is grounded. Between this load and the terminals P1, P2 of the first microcomputer 12, a remote control lock switch 17 and a remote control unlock switch 18 are connected. The computer 12 controls the indication control of the first indicator 13 and the drive control of a transmission circuit 14. The computer 12 contains a RAM and a timer and sends unlock key data during pushing the switch 17 and sends time data in the next. As the key code and time information are sent from the computer 12, temperature environment becomes better than a car clock and thus time information with high accuracy can be obtained. |
