Are you wondering about how to lock and unlock Honeywell Thermostats? It is pretty simple to do this, but you should also be familiar with the keys and terminology used for the thermostat.
Many of you are probably wondering how to unlock a Honeywell t4 Pro thermostat or How to Unlock a Honeywell T6 Pro Thermostat?
Don’t sweat; we’ve got this. The Honeywell ProSeries T4 and T6 thermostats may be unlocked and locked using the same method.
Before powering on the newly connected thermostat, be sure it is unlocked. If your children are constantly altering the temperature of a thermostat, you could also lock it away.
The first step while you unlock a Honeywell thermostat is to insert the PIN whenever prompted to start the procedure. You can follow the steps mentioned below to unlock a locked Honeywell thermostat,

What are the various types of Lock Modes available in Honeywell Thermostats?
The chief factor we lock the Honeywell thermostats is to limit who may modify the configuration on the gadgets.
We can choose between a ‘Full’ lock and a ‘Partial’ lock for our devices’ keypads.
Whenever you enter your device’s ‘Menu,’ you’ll notice this choice.
In the Honeywell thermostats, you may choose from three different sorts of locks.
The titles in brackets indicate how they will be displayed on the gadget:
- Full: The ‘Full’ lock option blocks access to the thermostat configurations entirely.
- Partial: Using the ‘Partial’ lock option, you may modify the temperature. All those other options will be unavailable.
- Off: In this lock option, the thermostat’s keypad would be unlocked.
A PIN can be used to unlock the ‘On’ and ‘Part’ locking settings.
If you often stray from your set timetable, but the locking option at ‘Part.’ If you generally leave the gadget to work on a schedule, configure the lock to ‘Full.’
You will save time this way. Please make sure you don’t overlook your lock code, though.
The lock mode is disabled when the lock code is entered and the system is switched to the ‘Off’ option.

FAQ’s About How To Lock And Unlock Honeywell Thermostat
1. When is the best time to lock your thermostat?
You’ll probably want to lock the thermostat in one of three scenarios.
- Children
If you have children who like to be children and touch things they shouldn’t, you might want to lock the thermostat to avoid a spike in your power cost.
- Airbnb
If you own an Airbnb, you could adjust the temperature to a specified setting that would save money on the energy cost. This could also be used to keep temporary renters from turning on the heat when they aren’t in the house.
- Owner of a Building
Suppose you have an office space, for instance, and you have the legal authority to regulate the property’s temperature. In that case, you can opt to lock or temporarily lock the thermostat to maintain a steady temperature all through the structure.
2. How do I release the hold on a Honeywell thermostat?
Simply altering the thermostat temperature will eliminate a temporary hold. To remove a permanent hold, hit the ‘(+)’ and ‘-‘ buttons simultaneously, then tap ‘Cancel.’
3. For how long does a Honeywell thermostat hold function last?
It takes 12 hours for a temporary hold on a thermostat to be lifted. If your thermostat is set on permanent hold, you’ll have to override it to get it off manually.
4. Installing Your Thermostat Lock Box
It only takes a few minutes to install your new thermostat lock.
- Place the lock box rear plate over the thermostat and mark the drill holes with a pencil.
- Drill holes at each of these locations with a drill.
- Plugin the wall plugs
- Attach the rear plate to the wall using screws.
- Attach the front of the lockbox and secure it.
Once you’ve installed your thermostat guard, all you have to do is choose a safe location to put your key and keep in mind you don’t lose it. You should expect a more functional building and lower utility expenditures as long as the thermostat lock guard is still in effect.
5. What You’ll Require for a Thermostat Guard Installation?
Installing the thermostat guard is a straightforward task that will most likely require just the equipment you already have on hand. Aside from the cover itself, you’ll need:
- Pencil
- Drill
- Plugs for the wall
- Screws
- Screwdriver
6. Choosing the Most Appropriate Thermostat Lock Box
To begin, if you have a smart thermostat, see whether it has any virtual lock settings. You may be able to set a passcode to restrict temperature changes to just those who have been authorized. Otherwise, an actual thermostat cover will be required.
For the guard material, you have a couple of alternatives. First, plastic is commonly used for thermostat guards. These are inexpensive, long-lasting, and typically transparent, allowing you to see the thermostat without having to remove the cover.
A metal lockbox would be your second alternative. Because they’re so tough, they’re ideal for places where tampering is a possibility.
The disadvantage is that you can’t see the thermostat before unlocking it, and it can become very much heated if left in the sunlight. So once you’ve decided on the style of thermostat cover you prefer, make absolutely sure you check your thermostat so that you can get one with the correct measurements. The thermostat cover would then be installed.
7. What Is the Purpose of Thermostat Locks?
The ‘lock’ feature on thermostats, including those manufactured by Honeywell, is a relatively new addition. They were created for one simple reason: no one wants someone tampering with their thermostat. So instead of constantly resetting your thermostat to your preferred temperature, you can lock it, ensuring your children cannot reach it.
8. Is it possible to use lock functions on all Honeywell models?
You’re not alone if you don’t like the concept of a lock mechanism on your thermostat. The best part is that you do not need to purchase a Honeywell thermostat with a lock feature.
There are a lot of Honeywell thermostats that don’t have any lock function at all. If you don’t have children, a lock-free thermostat is a must.
Having said that, all Honeywell thermostats that are wi-fi enabled include a lock feature. If you don’t need to keep your touchscreen locked, unlock it and leave it unlocked.
9. Where Can You Get Honeywell Thermostat Unlocking Instructions?
Several Honeywell models with a lock mechanism provide directions on how to unlock it. However, the simplest approach to figuring out how to unlock the specific product is to consult the owner’s manual for the thermostat model you own.
If you are unsure of the model number of the thermostat, check the thermostat’s ID plate on the bottom of the thermostat.
10. Is It Possible to Change the Passcode on Your Thermostat?
The strange thing about a number of Honeywell’s lockable thermostats would be that you can’t alter the preset passcode.
While you may use a PIN to lock the touchscreen, someone who knows what the default configuration is would be able to customize the temperature in spite of your wishes.
11. Can You Always Leave Your Thermostat Unlocked?
While this is mostly a matter of personal opinion, the fact is that most individuals do not require their thermostats to be locked the majority of the time.
Most individuals do not go out of their way to increase or decrease the temperature on their thermostat. If you live in a house with a lot of adults who can follow the rules, there’s no excuse for keeping the thermostat locked.
