Having a spare key at hand is hardly a new concept, but where people might have left them under the doormat or inside a flower pot in the past, these days we’re more security conscious. This might explain key safes’ boom in popularity, and in recent years, more people are investing in lock boxes than ever before.


Your thoughts might go straight to holiday accommodation and temporary rentals, but many people are now opting to store their own personal set of keys in a safe. They can be a great option if you want to leave keys to be picked up by a babysitter or dog walker, or perhaps you or a relative has a regular carer that needs access, or you might just be forgetful.

Either way, if you’re looking for a secure way to store your keys, we’ve picked out 10 of the best key safes on the market. We’ve also put together a helpful buyer's guide to further assist your next home security purchase.

Key safe buyer’s guide

Keys can be hard to remember, and everyone knows that gut-wrenching feeling when you arrive back at your front door after a long day and realise you’ve left them on the other side. In this situation, and many similar to it, a key safe would help save the day.

You could have a friend visiting while you’re out at work, or you could need to let a dog walker in or have a limited amount of keys for a big family. There are all manner of reasons to use a key safe, but if you’re considering buying one, then how do you choose between the thousands available?

Well, the right style of key safe is dependent on your needs, so we’ve made this buyer’s guide to help you find out what these are and the key safe best suited to you. Here we will help you figure out the pros and cons of different styles of safes and assist you in purchasing your next piece of home security equipment.

What is a key safe, and how does it work?

So what actually is a key safe? A key safe is a secure container designed to hold keys and keep them safe, so multiple people can use the same set, and also so you don’t lose them. The safe usually comes with a combination lock or digital keypad that only the owner can tailor and then share with other people they wish to have access to the properties’ keys.

Most key safes ask for a four-digit code to be inputted, which means there are over 10,000 different security codes that you can make.

Why use a key safe?

You might be perfectly alright carrying your key around in your pocket, but once you hear the advantages of a key safe, this might change. They are used for lots of different reasons, with the main two being security and ease of access to your house/property.

And, because key safes are useful for storing keys outside, they have become popular for holiday rentals where the homeowner is not in the area to hand over/pick up the keys.

They also make certain tasks a lot easier in personal properties, such as leaving a key out for family members, plumbers, a dog walker, or a house sitter. Basically, it is the new, safer version of leaving your key out under the flowerpot or the doormat.

How to choose the best key safe for your needs

If you’re unsure about which key safe is going to be best for you, then consider factors such as the size, material, and locking mechanism you want to have. Once you know these, it will make buying a key safe easier as you’ll be able to filter through the hundreds available on the market.

In terms of size, you should consider how many keys you will be wanting to put in at once and if the key safe you choose will allow this. On the material side, there are three main options; plastic, steel, and aluminium. They should all offer you good protection, but metals are typically more secure than their plastic counterparts.

Then on to the locking mechanism, where you should consider whether you prefer a combination lock or a digital keypad. Combination locks are more straightforward to use and require no batteries, while digital keypads can offer more advanced features, like time-limited access codes.

Where to install your key safe to maximize security

When installing a key safe, it's important to choose a location that is hidden from view and not easily accessible. Consider installing it in a discreet location such as a fence, wall, or outdoors on an object like a shed or bin house. Avoid installing it in plain sight or near an entry point where it could be easily spotted.

Another factor to consider is the installation process. Some key safes require drilling and mounting, while others can be placed using adhesive strips. Check the surface you want to place the key safe on and make sure you have the equipment to mount it.

Here are some best practices and top security tips to keep in mind when using a key safe:

  1. Choose a secure location to install the key safe.
  2. Choose a strong and secure code that is not easily guessable.
  3. Change the code frequently to prevent unauthorised access.
  4. Regularly check the key safe for signs of tampering or attempted access.
  5. Consider using a cover or concealing the key safe to make it less visible.
  6. Keep the key safe clean and dry to prolong its life.

How to set up and change the code of your key safe

Now you’ve brought the key safe, the next obvious step is to set it up. You will need to punch a code in, whether that’s digitally or manually. Usually, it’s simple, and you just have to follow the manufacturer's instructions for your specific key safe model.

Some key safes may require physical keys to open the container before setting up the code. If you want to change the code (especially useful for homeowners who are renting out their holiday property), you will probably have to access the internal locking mechanism. You’ll then have to enter the existing code and set a new one.

How to make your key safe last long

Once you have your key safe up and running, let's keep it that way. There are some good practices to maintain your safe so it can continue to guard your keys. Make sure it is clean and dry whilst also avoiding cleaning the safe with harsh chemicals or abrasive materials. Instead, use a soft cloth or sponge and mild soap to wipe it down.

Regularly check the locking mechanism to make sure it's working properly. Extreme temperatures or exposure to sunlight could cause the material to degrade over time, so this is something to keep an eye on. Consider investing in a weather-resistant key safe if you live in an area with harsh weather conditions.
