1. An electronic key apparatus comprising:
- encrypted code storage means for storing an encrypted code for unlocking an electronic lock;
pass data storage means for storing pass data;
data input switch means for inputting the same pass data as that stored in said pass data storage means;
data coinidence detection means for detecting a coincidence between the data input by said data input switch means and the pass data stored in said pass data storage means;
manual switch means; and
encrypted code transmission means for transmitting the encrypted code stored in said encrypted code storage means to said electronic lock when said coincidence is detected by said data coincidence detection means and said manual switch means is operated.

Abstract
An electronic key apparatus wherein an encrypted code for unlocking an electronic lock is stored in an encrypted code storage register. A password is stored in a password storage register. The same password as that stored in the password storage register, is input via a switch. The password input by the switch is compared with the password stored in the password storage register, by a coincidence detection circuit. When a coincidence is detected, the encrypted code stored in the encrypted code storage register is transmitted to the electronic lock, by a transmitter.
