New keys will NOT fit old doors. Apparently, the manufacturer of digital door processing, Texas Instruments, changed something and an incompatibility arose. I contacted PlexiDor to find out why none of the three new keys worked and they explained the problem. They send me a new circuit board (easy to replace) and 3 additional new keys. Excellent customer service.
