Abstract
An electronic lock that requires the user complete a wear leveling action prior to entering in the passcode. The wear leveling action causes the user to touch one or more portions of the touch interface that may not be associated with the passcode to distribute wear of the touch interface. These area(s) of the touch interface selected for the wear leveling actions could be determined based on a pseudorandom number generator and/or by tracking usage of the touch interface to identify less used areas.
