<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus capable of surely preventing an electronic lock from being shut up in a vehicle, the electronic lock, and a door remote controller using the electronic apparatus and the electronic lock. <P>SOLUTION: The present invention is provided with a first LF transmission circuit 12a for transmitting a request signal to an electronic lock 20, a RF reception circuit 14 for receiving a response signal with movement information of the electronic lock added to the request signal from the electronic lock 20 and on-vehicle machine side control means 11 for controlling locking/unlocking of a door in an own vehicle based on the change in a reception state of the response signal. When determining that it changes from a state of receiving the response signal from the electronic lock 20 to a state of not receiving the response signal, the on-vehicle machine side control means 11 determines that the electronic lock 20 moves from the response signal and locks the own vehicle, while when determining that the electronic lock 20 does not move, the on-vehicle machine side control means 11 keeps the own vehicle in an unlocked state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
