Abstract
A customizable combination locking system using textual combinations. The principle object of the present invention is to provide a method to create a lock that is capable of being set in any desired set of letters that spells words that are easy for the user to remember. These words are supplied as a list and the tumbler positions are created from that list. The resultant lock would be commercially viable, as it will use existing, standard lock mechanisms comprised of tumbler rings with ten positions (0-9) and two, three, or four tumblers. The letters that appear in each of the ten positions have been selected through the described process. Having been selected, each lock is capable of being set to one of several thousand actual word combinations.
