PROBLEM TO BE SOLVED: To make it impossible to unlock a door lock by providing a valid/ invalid setting means to set valid/invalid of an ID code without eliminating the ID code memorized in an ID code memory means from the ID code memory means. SOLUTION: It is possible to reuse an ID code of a remote controller without changing it by changing an inable bit of the ID code of the remote controller R which is discovered to '1', and even when an outside discovers the lost remote controller and tries to use the remote controller, as the inable bit of the ID code of the lost remote controller R is already changed to '0' at the time, it is impossible for the outsider to inlock a door lock. A valid/invalid setting means to set valid/invalid of the ID code without eliminating the ID code memorized in a memory part 14 as an ID code memory means from the ID memory means is provided. |
