How do you unlock a locked Honeywell thermostat?

Depending on the model of your thermostat, the process to unlock it may vary. Generally, you'll want to begin by pressing the 'Menu' button. Next, press the '+' or '–' buttons to go to 'LOCK' and press 'Select.' From there, press the '+' or '–' buttons again to go to the 'ON,' 'PART,' and 'OFF' options and press 'Select.' To unlock the keypad, press the 'CENTER' button and enter '1234' as the password. You can do so by pressing the '+' and '–' buttons to change each digit and then press 'Select' to confirm the number. Once you've entered all four digits, press 'Select' to finish unlocking the keypad.
