How to unlock Lux thermostat that's locked?

Resolved Question:

We have a Lux 1500 thermostat and it is locked. I can't unlock it and have tried a sequence to unlock it (up, down, next, hold, reset) and that doesn't work. A little lock shows on the screen and we can't adjust the temperature or make any adjustment.

Optional Information:
Make : Lux
Model : 1500

Already Tried:
Sequence: up, down, next, hold, reset in that order. Tried hitting the reset button while holding all four buttons down at the same time.

Have you pressed "next" 3 times and then "hold"?

That worked! I can now set the temperature. We are satisfied with the result.
