5 Best Key Safe Lock Boxes [2018 Update]

The price of a lock box – also known as a key safe – has been dropping in price in the last few years, which means that it’s a win for the customer.
 
You no need to hide the front door key behind the bin or underneath a rock*. A well positioned and secure lockbox are much more secure and offer peace of mind to different types of users.
 
We ask that you review the items listed below and we give our favourite 7 lockboxes and a further 2 you should avoid.
 
* If you still want to hid it under a rock, you can buy a rock shaped lock box which should deter the most ardent of burglars.

1. Supra - C500 Key Safe

This is the only POLICE APPROVED push button key safe

  • Manufacturer: Supra
  • Weight: 1.9 Kg
  • Internal dimensions: 7.9 x 7.9 x 6.3 cm

The Supra C500 key safe comes with a weatherproof cover made of plasticised rubber, helping to stop and rain or snow from weathering the item. As a bonus, it also acts to disguise the key safe from unwitting passers-by.

As tough as it is durable, the item is made of a heavy grade stainless steel and zinc-alloy and comes as a double wall construction.

It is the only mechanical lock box that has been endorsed as ‘Secured by Design’ by the UK Police and has also received accreditation by the Loss Prevention Certification Board.

Positives

  • The only mechanical police approved key safe.
  • Stores up to 6 keys.
  • 2 year guarantee.

Negatives

  • Very expensive.
  • Instructions can confuse some people.

2. Master Lock - Medium Key Lock Box (5401EURD)

  • Manufacturer: Master Lock
  • Weight: 0.39 Kg
  • Internal dimensions: 22.8 x 16.6 x 4.8 cm

A long time favourite, this Master Lock key safe is designed to have up to 10,000 combinations.

It comes with four pre-drilled holes to the rear, allowing you to mark off the holes before drilling into brick, stone or masonry. This item can be fitted with standard DIY tools i.e. an 8mm drill will suffice.

If the keys you’re going to store are for cylinder locks, then this will be good enough. However, with mortice lock keys, it is a bit fidgety. The issue is that the top half of the key safe houses the locking mechanism. This eats up a fair bit of space, meaning the area is little tight, especially if your mortice lock key is bulky. In this instance, we would recommend that you upgrade to the bigger Masterlock 5403EURD Key Safe.

As for longevity and security, the shutter door protects combination dials from weather, dirt and grime. The well constructed zinc casing will frustrate vandals that might be tempted to use a hammer or saw(!)

Positives

  • Indoor and outdoor use.
  • Durable design and scratch proof mould.
  • 10,000 different combinations.

Negatives

  • Can be a bit small for fobs or mortice lock keys.
  • The silver/grey colour does attract attention.

3. Sentinel Push Button Wall Mounted Key Safe

  • Manufacturer: Sentinel
  • Weight: 0.80 Kg
  • Internal dimensions: 26.6 x 15.6 x 7 cm

Takes up to 10 Yale type keys. Like the Supra C500, this is keypad lock box.

The purchase comes with four screws and you’ll need an 8mm bit to screw in to masonry.

The code can be any length and can be in any order, but any single number can only be used ONCE. It is a bit more complicated to use compared to combination digit locks, but some might consider a keypad style lockbox easier to use.

It is fairly spacious inside and it feels like a well designed product. It comes with a waterproof cover which also helps to give it a discreet look.

Positives

  • Push button digits.
  • Stores up to 10 keys.
  • Weather resistant with special paint.

Negatives

  • Somewhat expensive.
  • Not as secure as some other locks.

4. LDS Key Safe - Wall Mountable (KS-005)

  • Manufacturer: LDS
  • Weight: 0.52 Kg
  • Internal dimensions: 9.0 x 8.0 x 3.2 cm

Our favourite thing about this key safe is the outer protective cover. It acts as a weather barrier to stop and snow or rain from getting inside, but it also does a really good job of camouflaging the key safe.

We’re not a fan of having your wall mounted key safe being easy to spot, so once the plasticised rubber cover is on, it seamlessly sits alongside other wall mounted bits an pieces such as a broadband box.

Other than that, it is well build, has a modern feel about it and the size is pretty big inside – enough to hold keys and credit cards.

Positives

  • Key hook inside allows easy hanging of keys.
  • Stores up to 10 keys and credit cards.
  • Comes with a protective waterproof cover.

Negatives

  • A bit on the expensive side.
  • Digits can be hard to see during night-time.

5. Rhino Lock Secure Key XL Combination Safe

  • Manufacturer: Rhino Lock
  • Weight: 0.8 Kg
  • Internal dimensions: 14.5 x 10.5 x 5.5 cm

This combination locak by Rhino is a bigger size, meaning lots of space if you need to put more than a few keys in there. It is also a UK branded item, which is something we look out for. There are many Chinese knock-off sellers that sell on Amazon and eBay, so with something as important as home security, we would always opt for a UK, USA or European based company that carries out more rigorous checks.

With the sizing of it, the case will hold car keys and fobs in addition to the regular keys, cash and cards. It’s not quite big enough to leave your kids lunch in there, but the size is ample enough!

Positives

  • Largest key safe we have bought - lots of space!
  • UK branded item - feels more trusted
  • Rugged and attractive design

Negatives

  • Some buyers say the digits can be a bit stiff.
  • The screws that come with it are not great.
