LuxPRO Thermostat Locked? (How to Unlock)

Are you wondering why your LuxPRO Thermostat got locked out? You’re not alone; it happens sometimes—perhaps you got it locked in error or so. The lock feature in your thermostat helps prevent anyone else from tampering with your temperatures and other settings, so it’s not a defect.

And the good news is, you can easily unlock the thermostat yourself in a few seconds. If you’re not sure how to do that, you want to keep reading as I’ll walk you through the steps to unlock your LuxPRO Thermostat. Let’s begin!

How to Unlock a LuxPRO Thermostat

Generally, here’s how to unlock a LuxPRO Thermostat:

Press the NEXT button on your thermostat three times (NEXT, NEXT, NEXT), then press the HOLD button. This will remove the padlock icon from your LuxPRO Thermostat display, showing it’s been unlocked.

If this method doesn’t work for you, it appears that your thermostat model requires a code to unlock. What this means is, some LuxPRO thermostat models require the user to set a 3-digit code when locking it. And you must enter the code to unlock the unit. So tap the Closed Padlock icon on your thermostat display, and then enter the code and tap NEXT to unlock it.

If you’ve lost the code, or you’re probably not sure how your thermostat got locked, try the default code (000) to see if it works. If it doesn’t work, then you want to reset your thermostat to unlock it.

To reset your LuxPRO Thermostat, find the reset button on the right or left side of the device (a white circle button labeled “R. Reset”). Next, press and hold the button for about 5 seconds. This will reset your thermostat and remove the key lock.

Note: This reset will remove all your custom settings, so you’ll have to start all over again to program your thermostat.
