My keypad says I need a key when trying to perform a management operation (78* set time, 73* set date, etc).
You have programmed the lock using a green or red key from your system software. When you programmed the lock you selected the option to require key under the users tab.
Uncheck the require a key option under the user tab. Reprogram the key and upload the data to the lock. This will will then allow you to program without a key.
