Abstract
A method of gaining authorized entry into a secure location is provided. The method includes providing an electronic lock having a dial, the lock operably coupled to a microprocessor having memory for storing a user input code and a valid code. The user rotates the dial to activate power to the lock and a first random character is generated. The user again rotates the dial until a first user input character displays in the display. The first user input character is stored in memory and a second random character is generated. After the user has entered all characters of the access code, the microprocessor compares the user input characters with the valid access code stored in memory if the user inputted code comprises an authorized code an indicia is generated on the display to visually indicate to a user that the lock is capable of moving to the opened position.
