A key safe is a type of outdoor safe to store spare access keys to your home. While these safes have their benefits, they may also come with some risks to your home security, including the risk of invalidating your home insurance.

Key takeaways

  • Some insurance companies may reject a claim for theft if keys from a key safe were used to enter home

  • There are insurance-approved key safes on the market but whether specific ones are covered will vary depending on the insurer

  • Smart door locks and keyless entry systems are considered a safer option

What is a key safe?

A key safe or key box is a secure, weather-resistant box, typically mounted on the exterior of a property, that holds a spare key.

Key safes are normally accessed via a key safe code or digital keypad. 

Why might I need a key safe?

You might need a key safe to grant access to your home to people that don't have house keys for your property.

These might include:

  • Carers

  • Cleaners

  • Dog walkers

  • Tradespeople

  • Children

Key storage is also often used by Airbnb hosts, holiday homes, and short term lets – but bear in mind it will invalidate your home insurance if you haven’t declared using it as a holiday let.

Do key safes invalidate home insurance?

In some situations, a key safe can invalidate your home insurance policy.

It depends on your insurance provider and the specific policy you have in place. The best way to find out if the use of a key safe is covered by your house insurance is to check your policy documents or contact your insurer.

If you make a claim for a break-in on your home insurance, most insurers require evidence of forced entry to approve the claim. However, what is defined as 'forced entry' can become complicated when key safes are involved.

Some insurance companies may reject a claim for theft if keys from a key safe were used to enter home. Others may accept that a burglar breaking into a key safe counts as forced entry.

Some insurers will only accept your claim if you use a certain type of key safe, or one that meets particular security standards – more on that below.

Whether a key safe invalidates your buildings insurance can also depend on how you use it. If your key safe is of an acceptable standard and is used correctly and safely, your claim is more likely to be accepted.

But if it’s broken, poor quality, left open, or if too many people know the code, a burglary claim may get rejected.

Bear in mind, too, that if your key safe is for the use of paying guests – such as an Airbnb or sublet – standard home insurance won’t cover your property. You’ll usually need to take out a specialist insurance policy for your rental business.

What are the alternatives to key safes?

There are various alternatives to key safes when it comes to keeping a spare key somewhere, or letting people access your home.

Most of the alternatives are safer than just stashing a key in a plant pot or under a doormat.

In home insurance terms, it depends on what your policy says, as to whether a key safe is the best option.

Before picking one, check if you’ll be covered by your home insurance:

Key safes

Key safes themselves are generally considered quite secure (if certified by certain independent security bodies), and can be used quickly and easily by anyone who knows the code. They’re also relatively cheap and easy to install.

However, they can be broken into, and rely on the use of a physical spare key.

Smart door locks and keyless entry systems

Locks that use smart technology or other keyless systems – for instance, using a digital code, fingerprint, key card, or app – are somewhat more secure.

They also give you the option to only allow entry to someone once, and it’s quick and easy to change the code whenever you want.

On the down side, they’re a little more difficult to install, and require a power source too. Anything that requires an app will also add an additional barrier for people who don’t live there.

Video intercom systems

With a video intercom, you can grant access to your door remotely, often by using an app on your phone or other gadget – Amazon Ring is an example of this.

The main benefit is that you can personally see who is trying to gain access, and remotely open the door yourself. They’re much more expensive than a basic key safe, however, and require extra steps to install.

Are there insurance-approved key safes available?

Yes, there are insurance-approved key safes on the market. Again, however, bear in mind that different insurance providers vary in what they approve.

Some things you can look out for in key safes include:

Secured By Design

This is an official police security initiative. These products meet the ‘Police Preferred Specification’, meaning the UK police officially considers them safe.

Loss Prevention Standards (LPS)

The Loss Prevention Certification Board (LPCB) is a body that sets security standards. You can see products that meet their standards, and learn more about what each one means, on Red Book Live.

Sold Secure

This is a testing and certification house for security products, including key safes.

ISO accreditations

This means a product has been tested by an external, independent body, to meet certain standards.

Finding home insurance that allows key safes

The only real way to find home insurance that allows key safes is to check providers’ individual policies.

You’ll also have a better chance of having a claim accepted if your key safe is approved by one of the organisations listed above, and if you’ve taken clear steps to keep it secure – such as by installing it away from the front door and out of public view, and regularly changing the access code.
