Thanks Russell for getting back to me. I tried the steps, but was unsuccessful. However, I did manage to find the direct power source to the keypad......disconnected it and waited for 15 minutes, then reconnected and entered the information as if the keypad was back to factory service codes. Voila.....that seemed to do the trick. It could have been that I wasn't pressing the keypad numbers hard enough or waited too long, but everything is working fine now, so I'll just leave it alone.
Thanks for your assistance.
