Locking Thermostat Cover with Key
Still in plain view. Out of reach without the key.
- Changes take a keyThe hinged door locks with a key, and keys are included. Whoever holds the key decides the setting.
- Easy to readThe cover is clear, so everyone can still see the temperature, and nobody has to ask you what it’s set to.
- Room air gets throughIt’s vented on 4 sides and open at the back, so the thermostat can keep reading the room.
- Screws or tapeThe box has 4 screws, 4 wall anchors and double-sided clear tape, so you can choose how it goes on the wall.
Why cover it
One setting, one key, no more notes on the wall.
Most people who need this have already tried the polite way. There’s a sticky note that says please don’t touch. There’s a reminder in the group chat. Maybe there’s a quiet word with the new hire. It works for about a week. Nobody means any harm. They’re warm, or cold, and the buttons are right there.
A locked cover ends the back and forth without anyone having to be the bad guy. The temperature is still on show, so nobody feels shut out. Changing it takes the key, so requests come to one person and the setting only moves when it’s meant to. In a home, it’s even simpler. A small child who has found the buttons can look but can’t press.
The thing to watch with any cover is the air. A thermostat has to feel the room to do its job, so a sealed box would be the wrong answer. That’s why this one is vented on 4 sides and open at the back. When you mount it, keep the vents clear and don’t let tape cover them. The cover only needs to block fingers, and the room’s air can keep moving through.
Whoever holds the key holds the setting.
Three numbers to check before you order.
Take the width, the height and the depth of your thermostat, then hold them up against 8.26 x 5.7 x 2.55 in. Those are outside numbers, and the cover’s walls use up part of them, so leave room on every side. Depth is the one to watch. If you have a round dial or a bulky smart model, measure from the wall to the thickest point. The door still has to close over it.
Next, look at your wall. Lay a tape measure around the thermostat and check that nothing sits inside the space the cover needs, such as door trim or a light switch. Then choose how to mount it. Screws and anchors suit gyms, offices and restaurants, where the cover will get bumped. Double-sided tape avoids holes, and it needs a clean, smooth wall to grip.
Setup starts with a tape measure
Measure your thermostat
Check its width, height and depth against 8.26 x 5.7 x 2.55 in, and leave room for the cover’s walls.
Check the wall
Make sure trim or a light switch won’t block the cover. Your thermostat stays on the wall, because the back is open.
Pick your mount
Use the 4 screws and 4 wall anchors, or the double-sided clear tape on a clean, smooth wall. Keep the vents clear.
Lock it and test
Close the hinged door and turn the key. Check that you can read the temperature through the front.
Any thermostat more than one person can reach
Rentals, offices, gyms, restaurants and homes with kids. If you’re the one who sets the temperature but you aren’t the only one touching it, this goes on your wall. It comes with keys, 4 screws, 4 wall anchors and clear tape in the box. Measure your thermostat against the outer size and allow room. If it doesn’t fit, send it back inside 30 days. Shipping to the US, Canada, the UK, Australia and New Zealand is free and tracked, and most orders arrive 1 to 3 weeks after ordering.
The thermostat is handled. Next: the doors and windows.
