Abstract
Improved squiggle keys and cylinder locks include a squiggle key groove formed along a first broad surface of the squiggle key and a plurality of bittings formed along a second opposite broad surface of the squiggle key. The cylinder lock includes a plurality of rotatable discs that have groove-following elements that are rotated via the groove on the key. The rotatable discs operate to prevent a plug of the cylinder lock from rotating unless a correct squiggle key is inserted into a keyway in the plug. The bittings formed along the second opposite broad surface of the squiggle key are generally circular and have inner regions with a different depth than outer regions of the bittings. As a result, tumbler pins can be located along the inner and/or outer regions of the bittings which enables increased keying capabilities and variations and which enables a common lock to be operated by keys for different cylinder locks.
