Abstract

An electronic lock system senses codes 26 on a key 15 by means of opto-electronic, magnetic or other electrical means and compares the key code to a code stored internally in a memory. When the key code is equal to its respective stored code the lock activates an electrical clutch operated bolt 2, and changes the internally stored code to a new code. <IMAGE>
