A key safe is only as good as what it is bolted to · review
A wall-mounted key box with a sliding cover over the dials, which Amazon Basics states protects the mechanism from sand, salt, dust and dirt. Aluminum and zinc alloy, 3.5 × 8.6 × 12 cm (1.4 × 3.4 × 4.7 in).
The conclusion The cover is the reason to pick it. Small, sensible, and dependent on being bolted to masonry.
Key safes do not usually fail by being broken open. They fail by seizing — grit, salt and frost in the dials until the buttons no longer move — and then somebody forces one with a screwdriver and it never works again.
Slides over the dial and keeps the weather off the mechanism. Amazon Basics states it protects against sand, salt, dust and dirt, which is a precise description of what a coastal or exposed wall throws at it.
It is a small thing that decides how long the product lasts, and it costs nothing.
3.5 cm (1.4 in) deep. One or two keys, flat, without a fob. A house bunch will not go in, and it is worth measuring the key you actually intend to leave before ordering. The larger boxes in this hub take twenty keys and cost twice as much.
Bolted to masonry, out of sight of the street, not beside the door it opens. A key safe on a fence post or a stuccoed skin comes off with what it is attached to, and the code becomes irrelevant.
One spare key, on an exposed wall, for somebody who visits.

Because the dials are what fails, not the box. Grit, salt and frost work into an exposed mechanism until the buttons stop moving cleanly, and a key safe that will not open is exactly as useless as one that opens for anybody. A cover is the difference between a box that lasts and one that seizes.
One or two, realistically — the box is only 3.5 cm (1.4 in) deep overall. A bunch on a fob will not go in. If several keys need to live in it, the larger boxes in this hub are the ones to look at.
You can, and you should not. A key safe is only as fixed as what it is bolted to, and a post can be unscrewed, sawn or pulled. Solid masonry, with the supplied through-fixings, is the only sensible mounting.
