ABSTRACT:
A fault tolerant method of decoding an electronic key system includes the steps of reading a key return image from one or more actuated keys and comparing the read key return image to the previous key return image. The method also includes the steps of determining the actuated key from a net key return image between the read key return image and the previous key return image.
