You close the door and immediately realise that you have forgotten your key. In a situation like this, which many of us know well, a key safe can make your life much easier. It provides a secure storage facility for keys of all kinds, to which only authorised persons have access.

In an emergency, you simply enter your personal numerical code and remove the spare key. With our large key safe guide, we want to help you find the ideal key safe for you. Whether it should be wall-mounted or just hung up temporarily depends on your personal preference.

We have compared the two types and listed their respective advantages and disadvantages. This should make your purchase decision as easy as possible.


  • A key safe is a secure storage option for keys of all kinds. It is particularly suitable for allowing several people access to the flat, even if personal handover is not possible.
  • A key safe is protected against unauthorised access by a numerical code. You can choose between a key safe with a combination lock and a key safe with push buttons.
  • A basic distinction is made between wall-mounted and bracket-mounted key safes. Each variant has different advantages and disadvantages, but a wall-mounted key safe generally offers greater theft protection.

The Best Key Safe: Our Choices

There are many key safe on the market. But not all of them are convincing in terms of quality and security. To make it easier for you to choose a key safe, we have compared and rated several models. These key safe are our favourites:

Key safe: Purchase and evaluation criteria

To help you find your way through the many different models, we advise you on the criteria you should consider when choosing a key safe. The aspects that help you compare different key safe with each other include:

In the following paragraphs, we will explain the individual purchase criteria in more detail.


Depending on what you want to use a key safe for, a different key capacity is ideal. Typically, a mini key safe can hold up to 8 keys, which is usually more than enough for a single household.

If you need a key safe for a company or hotel, then a standard or large version is usually suitable. These can hold up to 20 or 50 keys and are usually equipped with key hooks to keep the safe tidy.

If you want to store a key card in the key safe, make sure that the key safe is the right size.

On the other hand, keep in mind that a key safe should not stand out too much in the first row. A mini key safe has the advantage that it can be easily hidden and placed in a variety of locations.

Locking mechanism

A key safe is secured against unauthorised access by a numerical code. There are usually two different types of locking mechanisms:

  • Key safe with combination lock
  • Key safe with push buttons

A key safe with a combination lock is the classic mechanical variant. The correct combination of numbers is entered by turning number wheels, whereby the length of the number code is usually limited to 4 digits. A key safe with a combination lock offers the advantage that the number code cannot be guessed from the wear of the knobs.

In the second variant, the numerical code is entered via a keypad, which is usually equipped with 10 digits. Since the number of digits can be extended beyond 4 digits, a key safe with push buttons offers even greater security against unauthorised access.

In addition, a key safe with push buttons offers the advantage that after entering an incorrect numerical code, there is usually a short waiting period, so that it is almost impossible to guess the code just by trying.

A Key safe with push buttons and app-controlled key safe usually only work electronically. We recommend that you choose a battery-operated model that does not need to be connected to the mains.

You can also find a key safe with a Bluetooth function that you can also connect to your mobile phone. You can then open the key safe quickly by pressing a button on your smartphone. You can also share access to your key safe with several people via an app, so you always have an overview of who is using the access and when.


To ensure that access to your property is secured in the best possible way, the key safe should be particularly robust. Some manufacturers divide their products into several security levels, which can help you choose the key safe with the appropriate security level.

Please note that a key safe are not covered by insurance!

If there is no information about the security level, the weight and the material of the key safe can also be important factors when choosing a suitable security device. As a general rule, a key safe should weigh at least 500 grams and consist of several layers.

The heavier it is, the higher the security it offers. As far as the material is concerned, key safes made of stainless steel offer the most reliable security in the first place. You can also often come across plastic models, which are a cheaper option but also less robust and much easier to crack.


Depending on where you want to install a key safe, you should be aware that not every model is suitable for severe weather. If you plan to mount it in a place that is not protected from rain and wind, then it makes sense to choose a weatherproof model.

Above all, it is important that the push buttons or number wheels are protected against moisture and cold. In addition, no water should penetrate the housing, as this could damage the locking mechanism and the keys inside.

So if you want to install the key safe outside in an uncovered place, choose a model that consists of a weatherproof housing. Aluminium housings, for example, are particularly weatherproof. Models with a protective flap that protects the code fields from the weather are also useful for outdoor use.

Key safe: Frequently asked questions and answers

Below we answer the most important questions related to the topic of key safe.

What is a key safe?

If you have ever locked yourself out of your own four walls in a hectic rush, then you certainly know how much time and effort it can take to gain access to your home.

A locksmith can cost up to 150 Pound at the weekend.

In such a case, a key safe would make your life much easier and save you a lot of money and nerves.

A key safe (often referred to as a key safe) is a special form of a classic safe that is used for the secure storage of all kinds of keys.

Since you can attach it directly to your house or in the immediate vicinity, it can give you or a trusted person access to the property in an emergency.

To make sure that no unauthorised person can get into your flat, the key safe is secured with a numerical code. You enter the code and remove your key quickly and easily in an emergency.

What types of key safe are there?

If you want to buy a key safe, there are basically two alternatives you can choose between. They differ in the way they are mounted.

Type Advantages Disadvantages
Key safe for wall mounting usually weatherproof, higher theft protection thanks to fixed anchoring, often equipped with key hooks drilling required, can only be mounted on straight surfaces
Key safe with bracket can also be mounted in hard-to-reach places, simple and quick attachment usually less robust, often without key hook

A key safe with a bracket is particularly useful for temporary use. It can be quickly attached to a wide variety of places, such as a railing or grille. However, since it is usually easier to crack, you should pay attention to a robust design when buying such a key safe.

In general, the wall-mounted version offers greater theft protection because it is firmly anchored in sturdy masonry with screws and dowels. In addition, you can also install such a model in the wall recess, which provides even more secure protection against break-ins.

For whom is a key safe useful?

In principle, a key safe is particularly useful if several people need access to a property without the owner always having to be present in person. This includes, first and foremost, larger families with children. Because if the child locks itself out of the flat, a parent does not have to rush out of work to let it into the house.

A key safe can save the emergency services valuable minutes in an emergency.

In addition, a key safe is ideal for holiday home landlords. It makes it possible to let guests into the house without having to hand over the key personally each time. It is also useful for letting tradesmen, cleaners or babysitters into the flat when no one is at home.

You can also use it to safely store other keys that you don't need every day. For example, you can store your car key or cellar key in a key safe.

How much does a key safe cost?

The price of a key safe varies depending on the manufacturer, the capacity and the material it is made of. In general, the average price range can be from 13 to 100 euros, although the price of a high-quality stainless steel safe with additional features can be much higher.

Type Price range
Mini key safe (up to 10 keys) approx. €13-40
Standard key safe (more than 10 keys) approx. 20-100€

So a key safe does not necessarily have to be a particularly large investment. It is quite possible to find a model with a reasonable price-performance ratio that offers reliable security for a reasonable price.

With cheaper key safes, we definitely recommend that you proceed with caution, as the lower cost should not come at the expense of security.

What are the alternatives to a key safe?

If you decide not to use a key safe, a locksmith is not the only solution when you lock yourself out of your home. We can advise you on how to replace a key safe:

Alternative Description
Leave keys with neighbours The easiest and quickest option is, of course, to ask your neighbours to keep the spare key to your flat. However, there is the disadvantage that the neighbours do not always have to be available immediately.
Key deposit service An alternative is the so-called key deposit service, which provides safe and reliable storage of your spare key. If you have misplaced or lost your key, the duplicate key will be brought to you by the quickest route.
Hide the key yourself Another option is to hide the emergency key in the vicinity of your home. However, it is better not to hide a key under a doormat or flowerpot, as these are the first places thieves look. Instead, you can find a variety of instructions on the Internet on how to make a safe key hiding place yourself.

Where should I install a key safe?

Before installing a key safe, it is important to think carefully about the best place for it. As a general rule, it should not be noticed immediately from the street. At the same time, you should be able to see it from your home.

Suitable places include a garage, a utility building or a shed next to the house. It can also be advantageous if your neighbours have an eye on the safe so that they can alert you in good time if an unauthorised person tries to tamper with it.

With a wall-mounted key safe, you should also pay attention to the strength of the wall. In general, when mounting a key safe, it is not recommended to mount it on an irregular masonry or an odd surface.

How do I set the numerical code of my key safe?

A great advantage of key safes is that you can change the numerical code individually. The individual steps differ depending on whether it is a combination lock or a combination code.

The standard procedure for setting an individual number combination for a key safe with a combination lock is as follows:

  1. Open the key safe with the valid opening code. When first used, the default combination is usually "0000".
  2. Push the reset button to the position specified by the manufacturer. This step may vary slightly depending on the specific model.
  3. Set the desired combination of numbers. Make sure that the individual number wheels are positioned correctly.
  4. Return the reset button to its original position.
  5. Close the key safe and adjust the number wheels.

If you have a key safe with an electronic numerical code, consult the user manual or the manufacturer to find out how to programme the user code. In principle, you can choose any three- to eight-digit code for most models.

What should I do if I have forgotten the numerical code for my key safe?

If you have forgotten the code, it is first and foremost important not to panic. It can happen to anyone and does happen quite often. Many people immediately reach for a bolt cutter and try to break into the key safe.

However, we would not recommend this to you, as an unprofessional emergency opening of high-quality models can take forever and usually leads to irreparable damage to the safe.

Sometimes there is no other option than to turn to a professional safe opening service. A professional can open the key safe in many cases without destroying it, so that you can eventually set a new code and continue using the safe afterwards. The costs of a professional emergency opening are usually much lower compared to a new purchase.


A key safe is a perfect solution for all notorious key forgetters. It is also useful for letting an authorised person into the flat without personal contact. A key safe can also be very useful in the event of an emergency, as the emergency services can get inside the flat more quickly.

To ensure that your keys are reliably protected from any attempted break-in, the key safe should be robust and ideally made of solid metal. A wall-mounted key safe, which is firmly anchored in the brickwork, provides special theft protection.

When buying a key safe for outdoor use, you should also consider whether the model is weatherproof and will ensure the safe storage of your keys even in bad weather.
