The Honeywell Thermostat Lock and Unlock Settings

The Honeywell thermostat offers you different lock settings, and it’s essential to understand them all. On the display screen, one of three settings will appear. For example, if your Honeywell thermostat is unlocked, it will display ‘off.’ On the other hand, there’s the partial lock setting. If your display screen shows’ part,’ you can change the temperature and nothing else.

However, the final setting is ‘on,’ which means that no settings, including temperature, can be altered until you unlock the Honeywell thermostat. If this is the case and you’re clueless about changing the setting, keep reading to learn how to unlock Honeywell thermostat.

When to Lock Your Honeywell Thermostat

There are several situations where you might need to lock your Honeywell thermostat; below are some.

You Have Kids

Kids will always be kids, right? Therefore, they tend to touch things they’re not supposed to. You might want to lock your thermostat when you can’t keep watch to prevent the electric bills from soaring.

You Run an Airbnb

If you run an Airbnb, you might want to keep the temperature at a certain level to reduce mounting electricity bills. This could also help you prevent temporary tenants from leaving the thermostat on when they leave the room.

Building Owner

If you own a building, you can legally choose to control the building’s temperature. You could also choose to partially lock, so occupants can control the temperature but nothing else. Alternatively, you can lock it to ensure a consistent temperature throughout the building.

How to Unlock Honeywell Thermostat

There are four types of Honeywell thermostats: T4, T6, 8000, and the VisionPro series. The steps for unlocking are slightly different, and we’ll explore them below.

How to Unlock Honeywell T4 Thermostat?

You have to follow three steps when unlocking this Honeywell thermostat; we’ve outlined them below.

First, press the ‘unlock’ option on the display screen.
The thermostat would then prompt you to enter a 4-digit password. If you haven’t reset the password, the default is 1234.
You can use the +/- buttons to choose the digits in the password. Simply press the ‘select’ button to move on to the next digit.
After pressing ‘select’ for the final digit, the password will be accepted if correct, and your thermostat will automatically unlock for your use.

How to Unlock Honeywell T6 Thermostat

Unlocking the Honeywell T6 model is easy if you have a 4-digit pin. However, if you don’t know the pin, you might have to go through many more steps to unlock the thermostat. The Honeywell T6 series has a touchscreen feature, and when the thermostat is locked, you’ll see a lock symbol on the screen. Below are simple steps you should follow to unlock the model.

Press the ‘lock’ icon on the screen, and a prompt to enter the passcode will appear.
It’s important to remember your passcode if you want to proceed with this step. Use the +/- signs on the screen to input the correct digits. Press the ‘select’ option after each correct digit.
After the last digit, your thermostat will unlock, and you can access the settings.

If you’re learning how to unlock Honeywell thermostat and don’t remember the passcode to your Honeywell T6 thermostat, there are some steps you can follow to still unlock your thermostat.

Open the Honeywell thermostat’s faceplate and look for a four-digit code at the top corner of the thermostat.
Your pin is the sum of that code and 1234. This means if the code is 1000, your pin would be 2234.
Once you get this pin, enter it into the thermostat using the steps above, and it will unlock your thermostat.

How to Unlock Honeywell 8000 Series Thermostat

Another type of Honeywell thermostat that’s relatively common is the Honeywell 8000 series. The steps to unlock this thermostat are quite similar. However, these models have a complicated user interface that can be difficult to unlock, especially when you didn’t lock it yourself. When locked, the display will read ‘locked,’ while it will display 0670 when unlocked. Below are the steps to unlock this Honeywell thermostat.

To begin, press and hold ‘Auto’ and ‘System’ together to start the unlocking process.
This would pop up a blank space in the middle of the screen; press and hold this blank key until the display screen changes again.
You will then see four digits on the left corner of the screen. You have to use the arrows on the screen to change the displayed numbers to 0670; this is the passcode.
Rather than choose between one and zero to select the locking mode, you’ll have to set the displayed digit on the right to zero with the arrows.
Once you enter the pin completely and select zero, click ‘done.’ This would finalize the process and unlock your thermostat.

How to Unlock the Honeywell VisionPRO Series

Unlike other Honeywell thermostat models, the VisionPRO thermostat is quite complex and follows different steps to unlock. However, below are the steps to unlocking this thermostat.

Begin by pressing ‘menu’ on the display screen.
Now, use the arrow button on display to navigate to settings.
Now, hit the ‘select’ button to continue.
A prompt would appear to enter the four-digit passcode to unlock settings, use the up and down arrow buttons to enter the four-digit passcode.
Press ‘done,’ and the thermostat will unlock, giving you access to the settings on the keypad.
