1. A keyless locking system for operation by a user, said system comprising:
- locking means movable between a locked position and an unlocked position; and
control means for controlling said locking means, said control means comprising;
means for selecting one of a plurality of operating states of said control means, said operating states including a lock combination programming mode for entering a programmed lock combination code having variable length, a locked mode for moving said locking means to the locked position, and an unlocked mode for moving said locking means to the unlocked position, said selecting means having an idle state and an active state wherein putting said selecting means temporarily in said active state and returning to said idle state causes said control means to enter said lock mode if said locking means is in said unlocked position, and causes said control means to enter said unlocked mode if said locking means is in said locked position, and putting said select means into said active state for a specified period of time causes said control means to enter said program mode, andmemory means for storing the programmed lock combination code and the programmed lock combination code length, said control means storing the programmed lock combination code and the programmed lock combination code length in said memory means only if the programmed lock combination code has a length that is greater than or equal to a minimum combination code length and less than or equal to a maximum combination code length.
