<p>PURPOSE:To improve the burglar preventing effect by preventing the dishonest act such as insertion of foreign material with the structure that a code is input by turning a door key cylinder. CONSTITUTION:When the lock signal is sent from a remote key 2, a control device 1 carries out an alarm mode routine under the condition that all doors are closed, and when each courtesy switch 10, 11, 12 of a door, a trunk and an engine and an intrusion sensor 13 detect the dishonest intrusion, the control device 1 operates a position lamp 15, a tail lamp 16 and a horn 17 for alarming. In the alarm mode, when a key plate 2a is inserted to a door key cylinder and it is turned within ten seconds, the control device 1 catches the code signal by the rotation detecting signal from a door key rotating switch 7, and in the case this code signal coincides with a registered code, the control device 1 cancels the alarm mode. In the case where the key plate 2a is not turned after passing ten minutes, the control device 1 performs the alarm operation to improve the burglar preventing effect.</p> |
