I don't know what I did but the thermostat is locked and I don't know how to get it unlocked. What do I have to do? Thanks.

4 KEYLOCK To prevent tampering with any of your settings or temperatures, most of the front panel buttons can be locked out by pressing the following four-button sequence: NEXT, NEXT, NEXT, HOLD. This sequence of keys will lock and also unlock these items: UP, DOWN, NEXT, HOLD, the Rotary Dial, and the Software Reset button. The “H” Humidity button, and both of the Mode slide switches are not locked out. When the Keylock is activated, a padlock icon will be visible in the area above the clock as shown below. The Keylock will be disabled if the Hardware Reset button is pressed.
