Low light option

Designed with a high-vis keypad and dials, this model is best suited to those who anticipate coming home in the dark, or want those they let into their home to be able to find a key safe, without assistance. It's also a great option for those with a visual impairment.

The best key safe: Sentinel Push Button Key Safe Twin Pack

Specifications
Best for: Ample storage
Material: Steel
Capacity: 10
Lock type: Push digit combo

+ Large key capacity 
Reasons to avoid
-Can type in key code any way round and it'll work

Perfect for those seeking a key safe with a large capacity, this is another option worth considering if you're looking to provide safe and secure access to your home.

Large capacity

Capable of holding up to 10 Yale-type keys, this Sentinel key safe has the highest capacity of any option on our list, making it great for large households with lots of doors or cars between them. 

Robust design

That large capacity sits inside a safe that’s made weather-resistant with special paint, and it has a reassuringly robust feel to it, as well as being easy to mount. 

Worth considering

Our only complaint is that while you can set your own combination for this, the key safe will unlock no matter what order you put your chosen numbers in, so it's best that you have a long code to ensure it can't be cracked.

How to buy the best key safe

When it comes to buying the best key safe to suit your requirements, there are few factors worth bearing in mind. These include:

Buttons

We've featured a combination of push buttons and rotation wheels, with some allowing you to set your own memorable number. It's worth considering which will best suit your needs.

Capacity

While it may seem obvious, many people fail to consider what size key safe they actually require, until it's too late. Take time to consider how many sets of keys you intend on storing at a time, and make a choice accordingly.

Design

Key safes with covers are less obvious. Plus, you may wish to consider how your key safe will affect the appearance of the entrance to your home. Something big and bulky will – obviously – have more of an effect than something more slimline. 

Is it actually safe?

While each key box on our list is verified secure by happy reviewers, our top pick all round, the Supra C500, is one of the best selling lockable key boxes on the market, and the first one to be approved by the police as part of the Secured by Design initiative. 

Do you want to replace your lock entirely?

Even more secure than installing a key safe is switching your regular locks for smart locks. This will not only make keys entirely redundant, but allow you to control who accesses your home with even greater precision – it's possible to provide one off access codes to those looking to enter your home.
