`ABSTRACT
`There is provided a mobile terminal capable of being
`protected against unauthorized use by a third party without
`using a dedicated key device . A plurality of mobile terminals
`are previously registered mutually . When unlocked among
`them , one mobile terminal communicates with another
`mobile terminal in a communication range of short - range
`wireless communications , unlocks the above another mobile
`terminal , and when out of the communication range , locks it
`again .
