1. Defender Wall Mounted Combination Key Safe

Best mid-size combination safe

best key safes Defender Wall Mounted Combination Key Safe
  • If, like me, you have a habit of losing keys or locking yourself out, this is the ideal type of key safe for you. The combination lock means that all you need to remember is the code!
  • Even if an intruder managed to rip the key safe off your wall, the keys are kept safe inside. They’d need to breach the safe itself to get at the contents.
  • Made with a solid zinc alloy body, the rounded corners and protective coating make this safe hard to get at. It’s well resistant to sawing and if positioned properly, hard to pry off as well.

  • More than a few users have complained about the drilling template that comes with the key safe. Check and re-check the measurements before you start drilling into your wall.
  • For some reason, this key safe doesn’t have an internal hook to hang your keys off. Compared with the other Defender product on my list, it’s a little less user-friendly.
  • Defender recommend using a 5 mm masonry drill bit to get the Thunderbolts in. Several users have complained that these holes are too tight. I’d go with a 5.5 mm bit to be sure.

Home safety aficionados Defender produce plenty of handy safety and security equipment. They also make a solid little combination key safe that’s perfect for stashing a spare. It’s big enough to fit a bunch of keys, and because it’s got a combination lock, you’ll never need a key to open it.

I’m a big fan of combination locks on key safes, and this one feels pretty good to me. The tumblers are smooth and each number on them is etched and painted, so they’ll last for ages. You can close the mechanism off from the worst of the weather with a sliding door too.

Classed as a medium-sized key safe, it will comfortably hold up to five Yale-type keys, so it’s got plenty of room in the interior. You mount it to a wall with four “Thunderbolts” that are luckily supplied, tighten them down, and you’ve got a safe place to stash your spare key. It’s an ideal key safe for someone with a rental property, an elderly relative, or forgetful children!

2. CDC DIGI Combination Key Lock Box[ SAVE 31% ]

Best budget combination key safe

best key safes CDC DIGI Combination Key Lock Box
  • This key safe offers excellent value for money. It might not have the extra features compared with the Master Lock light up safe, but it does the job you need it to do.
  • I like the fact that you get five screw holes in the back of the key safe. It means you have more options for mounting it, and you can add an extra screw for more protection.
  • Tumbler combination locks are a lot more intuitive compared with the push button system found on some key safes. They’re easier to operate, even for young children or the elderly.

  • Even though this little key safe has a weatherproof coating and a flap to cover the tumblers, several users have complained that the mechanism can seize up over time.
  • As some users have pointed out, the extra hole in the back of the safe leaves it open to the weather. It’s worth covering up the extra hole with tape or sealant for long term use.
  • The four screws that you get with the safe to fix it to the wall are a bit on the small size. They’re probably strong enough for the job, but for peace of mind I’d use bigger ones.

When you need to leave a key outside your home, holiday rental, or anywhere else that requires access, the best solution is a key safe. One of the best budget key safes I’ve come across recently is the CDC DIGI combination key lock box. It’s inexpensive, solidly built, and has an easy-to-change keycode to keep your valuables secure.

It doesn’t get much simpler or more streamlined than this little safe. It’s constructed from a zinc alloy that has good strength properties and has a weatherproof vinyl coating to protect it from the elements. Alongside good internal space is a four-tumbler combination wheel that allows for 10,000 possible combinations.

Attaching the safe to the wall is pretty straightforward too. Like most of the key safes on my list, it comes with four fixings and plastic wall plugs. You use the included wall template to drill pilot holes, tap in the plugs, and then do up the screws through the back of the key safe. Easy to fix to the wall and boasting a simple mechanism, it’s not going to fail any time soon.

3. Supra C500 Wall Mounted Key Safe [ SAVE 35% ]

Best push button key safe

best key safes Supra C500 Wall Mounted Key Safe
  • This is a wonderfully small and streamlined key safe. If you need to conceal where you stash your spares, you can really hide this little safe. It’s the smallest one on my list.
  • It’s the original police-accredited key safe. If they think it’s a good idea, I’m inclined to believe them!
  • Even though it’s small, the zinc body on this key safe is incredibly solid. A burglar wouldn’t bother to try and saw through it.

  • Compared with the Master Lock 5420EURD, there’s no weatherproof cover. Rainwater and dust could work its way into the mechanism over time.
  • There are fewer possible combinations to choose from compared to a combination lock - so it’s a bit less secure.
  • You can’t set a true combination. If you press the four numbers or letters in any sequence, the key safe will open.

For more than 60 years, Supra have continued to innovate in the field of locking systems for homes and commercial properties. They’re one of the most trusted brands when it comes to choosing the best key safe box.

I checked out the Supra C500 Wall Mounted KeySafe, and love the robust design. The Supra key safe uses a hard zinc alloy body that can resist puncture and is, as they say, “as safe as your front door”. The push-button lock allows you to choose your own entry code between 1 – 12 characters using numbers and letters.

This Supra key box is part of the police-backed “Secured by Design” initiative, so you can trust this is the best outdoor key safe that money can buy.

4. Master Lock Light Up Combination Key Safe

Best with light up dials

best key safes Master Lock Light Up Combination Key Safe
  • This is a solid, dependable key safe from one of the best names in the business. Master Lock have a solid reputation built over decades, and lots of people trust them with their valuables.
  • The weatherproof cover is a snug fit and will make sure no water can get into the key safe.
  • The light up dials mean you can place the key safe in a concealed location. It’s easy to see, so you could hide it away and still enter the combination.
  • The internal space inside the key safe is large enough for a small bunch of keys. There’s plenty of room compared with the Rhino secure home lock.

  • The light up part of the key safe requires batteries. They’ll probably last for ages, but it’s another consumable you’ve got to think about.
  • Several users have complained about the quality of the included mounting screws. For a seriously secure fixing, upgrade them to wall bolts or concrete screws.
  • Unless you position the key safe in a concealed area, a burglar could pull it off the wall with a crowbar. Make sure it’s positioned where it can’t be pried.
  • There’s nowhere to hang your keys inside the key safe. A couple of little hooks would make all the difference.

One of the biggest names in home security for more than a century, Master Lock make some of the best key safes on the market. The 5425EURD light up combination key safe is like having a mini fortress that only you can get into.

Their four-digit combination key safe is a weatherproof and totally reliable place to stash your valuables. You can stop leaving the spare key under the mat now. It’s an ideal outside storage space for entry cards as well thanks to the large internal size of the safe.

One thing I really like about this key safe is the light-up dial. When you open the weather cover, a small LED illuminates the combination rollers from behind. No more fumbling for a torch in the dark when you’ve locked yourself out!

This is a great solution for anyone who rents out their property or needs to leave a key for site access. You can give out the combination, and then change it at any time. Mounting the key safe is straightforward, and the instructions included with it are easy to follow.

  • The only key safe on my list to have a handy hook inside to hold your keys. It seems so obvious, but even the Master Lock 5425EURD has forgotten one.
  • The weatherproof front is just that. It’s a rubber case that envelopes the whole key safe. When it’s in place, nothing’s getting in or out.
  • The fact that Defender include Thunderbolt fixings is great. Compared to the smaller screws that come with other key safes, they’re much stronger.
  • There’s plenty of internal room in this key safe. Enough to store a bunch of keys, which is a welcome design feature.
  • A push-button locking system can be much easier to use for people with mobility problems. Rolling tiny tumblers isn’t ideal for anyone that has finger dexterity issues.

  • Several users have complained that the weatherproof case breaks too easily. The rubber “hinge” on the bottom wears out and splits, letting the cover fall off.
  • Compared with the four tumbler combination lock on the Master Lock 5420EURD, the push button system isn’t as secure. You can punch in the four number code in any combination.
  • Unless you locate this key safe in a corner, it might be easy to pry off the wall with a crowbar. Compared to the Supra C500 it’s square in shape. I prefer a rounded key safe.

For more than a quarter of a century, Solon Security have produced quality home security products under the Defender brand name. Gaining a Secured by Design accreditation, you can trust that their key box will be one of the best key safes in the business.

I like the Defender outdoor key safe I tried out. It’s simple, robust, and well designed. The large push buttons on the lockbox are easy to see and operate. This makes it handy for anyone with mobility problems. The entire front is covered with a rubber weather shield, so there shouldn’t be any problems with the wind and rain.

Lastly, the included Thunderbolt self-tapping bolts are some of the most secure fixings around. Luckily, they’re much easier to install than they are to remove. You can be sure that one of the best outdoor key safes on this list won’t fall off any time soon.

  • The internal space is incredibly generous. You get more than double the room compared with the Master Lock 5420EURD.
  • Unlike the Dexter Innovations key safe, the lock mechanism doesn’t steal a lot of the precious space.
  • You don’t just get one override key, but a pair of them.
  • Being able to override a combination lock is clever. If you run a holiday let and change the code so often you forget it, you can always use your backup.

  • This key safe doesn’t feature a weatherproof cover. The combination rollers are exposed to the elements, which could shorten their working life.
  • As good as the roof design looks, I’m worried that a thief could hook a crowbar under the “eaves”. It could be a weak spot.
  • It’s a sturdy key safe, but it’s made from an aluminium alloy. For extra protection against attack, I would always opt for steel. It’s harder to pry or drill.

Specialist security company Rhino Lock are a UK based firm. They’ve made it their business to manufacture a range of the best external key safes for the UK market.

The first thing you notice about the Rhino Secure Home lock is the design. Shaped like a miniature house, this master lock key safe is instantly recognisable. It adds a touch of character to your home security as well. The roof section should act as real-life weatherproofing as well.

Our favourite feature of this combination key safe must be the failsafe emergency key. It seems simple but having a way to bypass a forgotten code or damaged tumbler is another level of security. Combination locks are great, but if you forget the combination sequence, you’re stuffed!

7. Dexter Innovations Wall Mounted Key Safe

Best for small footprint

best key safes Dexter Innovations Wall Mounted Key Safe
  • I like the extra security fittings you get with this key safe. It comes with wall plugs as well as screws, and a big washer to stop it being pulled through a wall.
  • You can install the key safe on a wall or through the peep hole in a door. It makes it possible to install it if you’re not allowed to drill into an external wall in a rental property.
  • Dexter Innovations are a family-run UK business. They pride themselves on good quality control, which makes a change.
  • Changing the code is a piece of cake. It takes about 20 seconds once you’ve done it a couple of times. It makes the key safe a lot more secure if you’re keen to change the code often.

  • This key safe has one of those small weather covers that can work loose over time. They slide downwards as well, meaning that gravity is against them staying closed.
  • Opening and closing the key safe door can be tricky. There’s no easy way of getting a grip on the door. It helps to keep out thieves but can keep the owner out as well!
  • The internal space is good, but a lot of the top part is then filled up with the lock mechanism. You can’t easily store a bunch of keys, just single ones.
  • Compared with the excellent Master Lock 5425EURD’s light up keypad, it can be hard to see the tumblers on this one in the dark. Make sure you’ve got a torch to hand.

With an interesting roster of useful gadgets, Dexter Innovations have produced one of the best external key safes I’ve tried out. It’s got a larger internal space for your spare keys without being enormous on the outside.

It’s remarkably easy to install on a wall with four screws, and it should stay secure for a long time.

I like the sliding weather shield that protects the combination tumblers from the elements. This complements the black stealthy look of the lock box. It also helps it blend into the background effectively. This outdoor key safe is a simple solution for keeping several keys safe when you’re out and about.

  • The unique padlock style key safe presents new options when it comes to home security. You can leave keys or other valuables attached to door handles, fences, or railings if you need to.
  • The weatherproof cover is hinged, so you don’t need to worry about losing it when you open the key safe.
  • You could use the key safe with a length of chain or security wire as a combination padlock if you needed it.
  • The four combination rollers give you a possible 10,000 numbers to choose from. This makes it much harder to guess compared to the Supra 500 wall mounted key safe.

  • If you use this key safe on a door handle, make sure it doesn’t get in the way of the door frame. It can stop it from opening from the inside.
  • It’s bigger than you might think. 17.5 x 7.2 x 4.2cm is probably too large for some doorknobs. Carefully measure where you want it to go, to avoid disappointment.
  • A shackle type lock isn’t quite as secure as one permanently attached to a wall with anchors. This key safe is more suited to allowing temporary access than anything else.
  • Compared with the Master Lock 5420EURD, the internal space is shorter. It might not be big enough for some security key cards.

Another stellar key safe from the trusted team at Master Lock, the 5420EURD select access lock box is a formidable bit of kit. If you don’t fancy drilling into your wall or it’s not possible to mount your key safe, this is like a padlock with benefits.

Featuring a snug hinged weatherproof cover and sturdy steel construction, this is a tough and lockable key store. It won’t get damaged by the wind and rain and has space for four large keys inside.

I really like the removable shackle on this key safe. It means you can fit the entire assembly over a doorknob or on a railing if you need to. It makes this key safe wonderfully versatile, an ideal solution for estate agents, holiday home rentals or other times when temporary access is needed.

The four-digit combination lock feels completely solid and clicks round with positive stops on the numbers. I think this is an ingenious way to temporarily give access to someone, or when you can’t permanently attach a key safe to a wall.

Harry's Smart Buying Tips

  1. The best key safes should have a robust zinc or aluminium body to protect them from hammering and prying.
  2. It’s important that the combination keys or push buttons are either protected by a waterproof cover or weather shield.
  3. Don’t neglect wall fixings – ensure quality bolts and screws, washers and plugs are all provided.
  4. It goes without saying that the space inside the key safe should be large enough to contain your keys and valuables.

How to Choose the Best Key Safe

Not having enough sets of keys for each household member is a common problem, and if you or members of your family are regularly finding yourselves locked out of your home, a key safe is a great option. 

Hiding your key in the vicinity of your home (such as under a doormat or in a plant pot) is a huge security risk, as thieves these days know exactly where to look. The best key safe should be virtually impossible to tamper with, so only those with the code will be able to access your keys. 

Key safes are also very useful if you are heading off on holiday and relying on a friend to water your plants, running a B&B, or having someone in to walk the dog while you are at work. Some key safes can be set with temporary codes, which is a great option if you’re having guests staying for just a short time. 

There’s a range of key safes on the market today and, as you’d expect, it’s essential that your key safe is good quality and robust. Not sure what to look for? Take a look at this buyer’s guide. 

Access Method

The first thing to look at is the access method. Key safes are digital, mechanical or electronic. For combination key safes, you should select a safe that has a very large choice of possible combinations. The longer the code, the harder it will be for someone to guess it. 

The most common type of key safe is a three or four-dial combination key safe.

Digital safes are another good option. These allow you to access the safe using a smartphone app and usually connect via Bluetooth. 

Build Quality

It’s essential that your new key safe has a good build quality to prevent it from being broken into. The design should be tamper-resistant. 

Poor quality key safes will be easy to break into and may be able to be pried from the wall, putting your security at risk. 

Weatherproofing

Even if your key safe is going to be installed undercover, for instance in a doorway, it’s still important that it’s weatherproof. A key safe without full weather resistance will weaken over time and be easier to break into.

The key safe itself should either be fully weatherproof or come with a weatherproof cover. Make sure you purchase a key safe which has been designed for use outdoors if you’re going to be storing it outside your home. 

Wall Fixings

The wall fixings are arguably just as important as the access method of the key safe. If it’s not firmly attached to the wall, someone may be able to pry it off and get inside. Use the wall fixings that come included or, if there are no fixings included, ensure you purchase good quality fixings. 

Size

The size is something not many people think about but is actually very important. How many sets of keys are you wanting to store? If you are only wanting to store one small set of keys, you won’t need a large key safe. If you’re wanting to store a number of keys, you’ll need more space inside. 

Those with a lot of space inside may have hooks for hanging your keys. These can also be installed inside your home and used to store spare car keys, house keys or garage keys. 

Security & Safety

Many people are against key safes because they believe they are easily tampered with. So long as they are installed correctly and not in plain sight, you shouldn’t have any problems with your key safe. 

One thing to look for is a police-accredited design. These have a ‘Secured by Design’ logo, meaning they conform to the Police Preferred Specification. Generally, these will be safer than others on the market as they’ll have anti-tamper mechanisms. 

It’s important that your key safe is installed in a concealed area. While it doesn’t need to be completely hidden, you should follow the manufacturer’s guidelines when it comes to installation. While very high-security key safes can be installed within sight, poorer-quality boxes should be placed out of sight. 

While hiding your key safe seems like a good option, this isn’t actually as safe as you may think. Having a key safe which is hidden away means that if a burglar does work out its location, he’ll be able to tamper with the safe without being seen. In this instance, having a key safe at the front of your home can be safer, perhaps combined with a video doorbell

Providing your code is changed on a regular basis and the key safe is installed correctly, you shouldn’t have any problems with security. 

It’s worth checking with your insurance provider before installing a key safe, as some key safes can invalidate your home insurance. 

Extra Features 

Key safes these days are much more advanced than they used to be, and many come with extra features to help make them easier to use. 

Light-up dials are a great option if you’re returning home in the dark. You should make sure the dials are only illuminated when you either press a button or remove the cover (as a light-up key safe will be very noticeable for thieves!). Light-up dials will make it easier to get into the safe quickly, and may be a welcome feature in the pouring rain! 

Digital key safes can connect to your smartphone. These usually work alongside an app, which will inform you every time the safe is opened or someone has attempted to open it. These are generally very secure.  

The ability to create a temporary passcode is also a feature of many digital key safes. This is a good option for those running B&Bs, who want their guests to have access only for a short period of time. It can also be handy if you’ve got builders, gardeners or other tradesmen who need access to your home for a few days or weeks at a time.

Key Safe FAQs

Although all key safes are built differently, opening them is usually quite similar. You’ll have to input the code before either turning a knob or pressing down on a slide mechanism. If it doesn’t work the first time on a tumbler combination key safe, you roll the numbers around to reset them. On a push-button key safe, there should be a “clear” button that resets the process.

The best key safes allow you to change the code easily, and some even allow you to choose a code length from 1 – 12 digits. The process will vary depending on the key box, but it will usually involve the following steps:

  1. Enter the correct code to open the key safe box
  2. Pressing an internal lever or button will allow you to set a new code on combination tumbler locks
  3. For push-button key safes, press the internal button to reset, then use the included key to input a new code
  4. Close the key safe again for the new code to be set
