Decided to buy this larger size key safe as the other ones jam so easily when you store more than 2 keys inside.
This one can hold 7 or 8 keys with ease!

Larger Key safe!

Bigger than standard key safe- big enough to hold key card or bunch of keys etc. Nicely made quality product at a good price.

A much bigger space for the keys

Good solid Key safe. Bought the smaller one initially but although good quality, wasn’t quite big enough for what I needed. Works as it should.

Kiwi Steve UK Verified Purchase

Just as is advertised, well built, takes up to 4 x keys depending on type and if without large key tags. I have installed over 100 of these externally all across the UK over the past few years and never had one successfully broken open. So I am very happy to recommend these regardless of where you require to install them.

Good: but improvement is nevertheless possible.

Thersites Verified Purchase

Appropriate size and construction for securing a small-medium size bunch of keys. Several minor ways in which it could be improved. The 4 fixing holes have low tolerance for positioning error and the lowest of these cannot be pilot-drilled with the box already on the wall. If the design doesn't change, fix the lowest screw first and drill pilot holes through the others to locate them correctly.

But if the top & bottom holes were made vertical and horizontal slots, this process would be easier. Also, a useless wire key hook is supplied to go onto the top fixing: It's too flimsy, distorting as the screw is tightened, and it's too low in the box, wasting the internal space above it that long keys need. And while suitable (stainless Philips PH2) screws are supplied, you'll need to have your own plugs for fixing into masonry. I think the screws are a bit short - OK on a brick face, but questionable for old render, especially if textured.

Great size

Great size & easy to fit. As this is the deeper safe you can actually fit in a proper bunch of keys.
