## Questions & Answers

**Q: Didn’t come with instructions how do I install?**
A: Take your Thermostat off the wall run the wiring through the holes on the backing plate replace with the same screws you take the thermostat off the wall with wire Your thermostat back up and put the face plate on in Lockett

**Q: How do I contact someone for a key? My package came with a locked thermostat box and no key?**
A: Return the box...it is the best way.

**Q: If I buy more than one, will all the keys be the same key?**
A: the covers I bought were keyed differently.

**Q: can this be mounted vertically or horizontally?**
A: Although I think it was designed to go over a vertical thermostat, which is how my thermostat was mounted. I see no reason why it wouldn't work horizontally. I will say although it is lockable and designed to keep reasonable people out it is not very heavy duty, it would be very easy for someone other than my 90 year old mother to break into it.

### ⭐⭐⭐⭐ Good Product
*by G***8 on December 24, 2020*

This product is well made. I had to use the 2nd mounting plate for wall mount to make the cover work with my thermostat. That said, the fit was still a bit tight as seen in the attached photo where the temperature setting levers interfered with the cover box and does not allow for free movement for temperature adjustment. The problem with the dimensions that the manufacturer listed as the 'inside dimension' is that it is the inside dimension of the cover but it does NOT take into account of the key lock opening protrusion into this space on the backing plate where the thermostat has to fit into!!! This key lock opening is in the back plate so it technically is not inside the cover but makes a difference. As can be seen in the enclosed photo, the thermostat is installed as low as possible and is forced against this key lock opening and yet, the temperature control levers on top still comes into contact with the cover box!!! Be sure to measure your thermostat height INCLUDING the temperature set levers and add ONE INCH just to be sure it will fit!! I give it a TWO STAR for incorrectly stating the inside dimension as it should have taken into account of the protrusion of the lock opening that is on the back plate!!!
