Abstract

The invention is a keypad which forms the access code input interface of a mechanical digital lock control panel (03), whereby the key symbol display comprising numbers 0-9 can be randomly and automatically rearranged about when a user inputs an access code. The access code input is actuated via the physical depression of the buttons on the keypad, each button comprising a transparent polycarbonate casing (02) housing a small Light Emitting Diode (LED) array (01) which presents the key symbol for the user. (Figure 1 is to be included along with this abstract for publication.)
