Abstract
Programmers for an entry control system, which operates to automatically control access to an area upon contact of an electronic key with a data port, employ data carriers housing ROM chips. The chips have a unique data code which corresponds to an elemental key or a code. In one form of the programmer, a membrane keypad addresses the ROM chips for inputting commands to program a controller. In other embodiments, the programming chips are mounted to a flexible board and are positionable to directly contact a receptacle port for the controller.
