ABSTRACT:
This invention relates to an apparatus for keeping a spare key in the car. Only when the numbers of the revolving rings are set to the predetermined numbers, a spare key can be taken out because the cap of the apparatus is released from an inlet of the fuel tank. Although a driver has lost his car key or locks the door with his key being left in the car or he does not have a key, he can drive his car by utilization of a spare key which is installed under the fuel tank cap. In case his secret number for the spare key is known to others, he can easily change the number to a new number. And accordingly, although the number for his spare key is disclosed to others, an immediate change of the number prevents his car from being stolen.
