Over the last few years the key safe for the post box has grown rapidly in popularity.

Traditional key safes are usually installed by drilling 4 holes in a wall or other flar solid surface, then fixing the key safe to this surface by passing screws through holes pre drilled in the back of the key safe to make a very secure fixing.

Whilst this method is still considered the most suitable for most installations, it does not suit every situation. There are also padlock style key safes where the shackle can be fixed to a railing or such like, but again this does not suit everyone.

So you want to have a key safe but you are not able, or do not want, to find a drill and make the necessary holes in the wall to use traditional fixings. You have looked at padlock style key safes but have no where to fix one so .... is there another option ?

More and more people are giving a resounding yes to this questions. The key safe for the milk box is becoming one of the most popular ways of installing a key safe. The key safe for the post box has a number of advantages over traditional installation methods and is generally very quick and easy to install.

The key safe for the post box has three different installation methods, each with their own positive and negative attributes :
  • The magnetic key safe for the post box

    A small, lightweight key safe with a 3 digit wheel combination.

    The magnetic key safe for the post box is very easy to install, but its size can make it a little difficult to manipulate the combination wheels, and changing the code is a little fiddly. The lightweight construction makes it less robust than the solid metal key safes.

  • The key safe for the post box with glue

    Two key safes are recommended, the Masterlock 5401 and the Supra S5. Both of the safes are traditional key safes that can also be installed with screws. The Masterlock 5401 has a 4 digit wheel combination, the Supra S5 a 10 digit button combination.

    Of the two key sasfes for the post box with glue, the Supra S5 is more robust and has stronger security as well as a full neoprene cover. It is the most popular key safe in the UK. The Masterlock 5401 is easy to use with its hinged door and is probably the most popular key safe in Switzerland.

    The installation with glue is relatively simple requiring no tools. The glue can take up to 24 hours to completely harden, but when set it forms a very strong bond.

    The key safe for the post box with glue should be viewed as a permanent installation.

  • The key safe for the post box with Velcro

    The Masterlock 5401 is recommended for this type of installation. As well as being the most popular key safe for the Swiss market, it is relatively lightweight which suits this installation. The key safe comes compelete with a strip of strong Velcro tape, approximately 10cm by 5cm. This extra strong Velcro tape is able to hold weights of around 7kg, making a very strong fixing.

    The installation of the key safe for the post box with Velcro is very simple and can be completed in literally seconds. From those viewing the key safe after it has been installed, there is no clue that it has been installed with Velcro.

    Once the key safe for the postbox with Velcro is no longer required, it can be removed although this will require some effort to seperate the Velcro strips, but, it can be removed. The ability to remove the key safe along with its very simple installation, are the main benefits of the key safe for the post box with Velcro. Because of these two reasons it is becomming more and more popular with home care companies (SPITEX).

No matter which installation method you choose, each key box for the post box can be installed without tools and with relatively little effort. The main differences are the levels of security offered by each solution, and the permanence of the installation.

How to install your Key box in your letterbox

There are 3 main options for fixing a Key box inside of a milkbox as follows :
Installing your post box key box using glue

We recommend Pattex adhesive as it forms a very strong bond, it can withstand a wide temperature range and it is easy to use.

Install the key box using the glue supplied as follows :
  • Clean the rear surface of the milk box that you wish to attach to
     
  • decide exactly where the safe will be attached remembering to leave a small gap between the bottom of the key safe and floor of the milk box. Use a 50mm spacer (or larger) to create this gap.
     
  • Apply the glue to the rear of the key box following the manufacturers instructions as written on the packaging.
     
  • Hold the key safe in place until the glue starts to dry and it can support its own weight.
     
  • While the glue continues to dry, place a suitable object under the key box to help support its weight while it dries.

When using glue or Velcro, some basic rules should be followed :
  • For key boxes with doors hinged at the bottom of the safe (such as the Masterlock 5401), make sure that there is a minimum 50mm clearance under the safe to allow the door to fully open.
     
  • With hinged door key boxes, attach to the rear wall to make changing the code as simple as possible.
