What Is a RADAR Key? Who Can Use One & Where to Get One

If you have ever come across a locked accessible toilet in the UK, there is a good chance it requires a RADAR key.

A RADAR key, also known as a National Key Scheme key, gives Disabled people independent access to thousands of locked accessible toilets across the UK. You will find them at train stations, shopping centres, public buildings, tourist attractions and many other places.

They are a small piece of accessibility equipment, but they can make a huge difference when you are out and about. Instead of having to find a member of staff and ask for a toilet to be unlocked, carrying your own key can give you quicker and more independent access.

Of course, getting through the door is only part of the picture. The accessibility of the space inside matters just as much. You can read our full guide to what makes a public toilet accessible to learn more about the features that can make a difference.

What is a RADAR Key?

A RADAR key is a large key designed to unlock accessible toilets that are part of the UK's National Key Scheme.

The scheme was introduced by the Royal Association for Disability and Rehabilitation, known as RADAR. The organisation later became part of Disability Rights UK, which continues to support the National Key Scheme today.

The National Key Scheme gives Disabled people a way to independently access accessible toilets that have been locked, rather than having to find a member of staff each time.

What does RADAR stand for?

RADAR originally stood for the Royal Association for Disability and Rehabilitation.

Although the organisation no longer exists separately, the name RADAR key is still commonly used.

You may also hear the same key described as:

• a RADAR key

• a National Key Scheme key

• an NKS key

• an accessible toilet key

What does a RADAR key open?

A RADAR key opens accessible toilets fitted with National Key Scheme locks.

You can find these toilets in places such as:

• train and bus stations

• shopping centres

• supermarkets

• cafés, pubs and restaurants

• tourist attractions

• public buildings

• libraries

• parks

• council facilities

• some public toilets

Not every accessible toilet in the UK uses a RADAR lock, so carrying a key does not guarantee access to every accessible toilet you come across.

Some toilets are left unlocked, while others may use a different system or require you to ask a member of staff.

Who can use a RADAR key?

RADAR keys are designed for Disabled people who need access to accessible toilet facilities.

You do not have to be a wheelchair user, and your disability or health condition does not have to be visible.

There are many reasons someone may need an accessible toilet. This can include people with:

• mobility impairments

• chronic illnesses

• bladder or bowel conditions

• conditions that make waiting for a toilet difficult

• balance or fatigue problems

• non-visible disabilities

• other access needs requiring the additional facilities or space

It is important not to make assumptions about whether somebody "looks Disabled enough" to use an accessible toilet.

Different people need accessible toilets for different reasons.

Do you need proof of disability to get a RADAR key?

This can depend on where you get your key.

RADAR keys can be bought directly from Disability Rights UK, while some councils and local organisations also provide or sell them.

Individual councils may have their own eligibility rules, so it is worth checking your local authority if you would prefer to get one locally.

You can also buy an official RADAR key directly from Disability Rights UK.

Why are accessible toilets locked?

Many accessible toilets across the UK are kept locked and require a RADAR key to enter.

The National Key Scheme was introduced to give Disabled people a way to access these locked facilities independently, without having to find a member of staff each time.

However, a locked accessible toilet is still an additional barrier.

It means Disabled people may need to remember to carry a RADAR key, obtain one in the first place, or find a member of staff if they do not have one. A broken lock, missing key or inaccessible access system can also leave someone unable to use the toilet when they need it.

Accessible facilities should be easy to access when they are needed. While carrying a RADAR key can provide more independence within the current system, ideally Disabled people should not have to overcome an additional locked door to use an essential facility.

Why are RADAR keys useful?

For someone who regularly needs accessible toilets, carrying a RADAR key can remove a lot of unnecessary stress.

Having your own key can mean:

• accessing the toilet yourself

• not having to search for a member of staff

• not having to explain why you need the accessible toilet

• having one key that works with National Key Scheme locks around the UK

• being better prepared when travelling

• having more independence when out and about

This can be particularly important for people who need to use a toilet urgently.

If you have just arrived at a busy train station, for example, the last thing you want to do is spend ten minutes trying to find someone with the toilet key.

Does one RADAR key work everywhere?

A genuine RADAR key is designed to work with toilets using official National Key Scheme locks across the UK.

That does not mean the key will open every accessible toilet in the country.

A toilet may:

• not be part of the National Key Scheme

• be left unlocked

• use another type of lock

• require access through staff

• have a faulty lock

It is more accurate to say that one RADAR key should work with RADAR or National Key Scheme locks around the UK.

Where can you get a RADAR key?

One of the easiest options is to purchase an official key directly from Disability Rights UK.

You can order a RADAR key from the Disability Rights UK shop here.

You may also be able to get one through:

• your local council

• mobility shops

• disability organisations

• some community organisations

• online mobility retailers

If you are buying online, it is worth checking that you are buying a genuine key. Very cheap copies are widely available, but poorly made keys may not work reliably with every official lock.

How much does a RADAR key cost?

RADAR keys are generally inexpensive, although prices vary depending on where you buy one.

Rather than relying on an old price, check the Disability Rights UK RADAR key shop or your local council for the latest cost.

Some councils may also provide keys free or at a reduced cost to eligible residents.

Can you use a RADAR key if you have an invisible disability?

Yes.

You do not need to have a visible mobility impairment to need an accessible toilet.

Accessible toilets can be important for people with many non-visible disabilities and health conditions, including conditions that affect continence, fatigue, pain, balance or how urgently somebody needs to use a toilet.

This is why nobody should be challenged simply because they do not "look Disabled".

Access needs are not always visible.

Is a RADAR toilet the same as a Changing Places toilet?

No.

A standard accessible toilet and a Changing Places toilet are different facilities.

Changing Places toilets are designed for people who need more space or additional equipment than is available in a standard accessible toilet. They typically include features such as an adult-sized changing bench, hoist and enough room for the Disabled person and anyone supporting them.

Some Changing Places toilets may use RADAR keys or other access systems, but having a RADAR key does not mean a standard accessible toilet will contain Changing Places equipment.

You can find out more about the features that matter in our guide to what makes a public toilet accessible.

Does having a RADAR key mean the toilet will be accessible to you?

Unfortunately, no.

This is one of the biggest problems with using a single word like "accessible".

Two accessible toilets can be completely different.

Depending on your access needs, you may need to know:

• how wide the doorway is

• whether access is completely step-free

• how much transfer space there is beside the toilet

• whether transfer is on the left or right

• whether grab rails are available

• whether there is a lowered sink

• whether an emergency cord is present and within reach

• whether there is enough turning space for your wheelchair

• whether the door is heavy

• whether equipment or furniture is obstructing the space

A RADAR key can unlock the door, but it cannot tell you whether the facilities on the other side will work for you.

That is why detailed accessibility information is so important.

What should you do if your RADAR key does not work?

If your key does not unlock a toilet, do not assume that your key is necessarily the problem.

The lock itself may be damaged or faulty.

If you are in a staffed venue, speak to a member of staff and let them know there is an issue.

For council-managed public toilets, there may be contact information nearby for reporting faults.

If your key regularly fails to work in different locations, it may be worth replacing it with an official RADAR key.

Tips for using a RADAR key

There are a few simple things that can make carrying and using your key easier.

• Keep it somewhere easy to reach rather than at the bottom of your bag.

• Attach it to a distinctive keyring or lanyard so you can find it quickly.

• Knock and check whether the toilet is occupied before unlocking the door.

• Check any red or green occupancy indicator before entering.

• Report faulty locks or inaccessible facilities when you encounter them.

• Consider keeping your RADAR key permanently in your handbag, backpack or wheelchair bag.

It is one of those small accessibility tools that can be incredibly useful to always have with you.

Can you use a RADAR key outside the UK?

The RADAR National Key Scheme is a UK system.

Other countries may have their own accessible toilet schemes or key systems, so it is worth researching what is used at your destination before travelling abroad.

If you are planning a trip, do not assume your UK RADAR key will work internationally.

Find accessible toilets and places before you visit

Having a RADAR key can help you access a locked toilet, but knowing what the facilities are actually like before you arrive can make planning much easier.

Sociability helps Disabled people find detailed accessibility information for cafés, restaurants, bars and other places across the UK.

Instead of simply telling you that somewhere is "accessible", Sociability lets you look at the individual features that matter to you so you can decide whether a venue works for your own access needs.

Download the free Sociability app to explore accessibility information before you visit.

You can also add places, photographs and accessibility information yourself, helping the next Disabled person planning where to go.

Final thoughts

A RADAR key may be small, but it can remove a significant barrier for Disabled people.

Being able to unlock an accessible toilet yourself means less waiting, less searching for staff and greater independence when travelling, socialising or simply going about everyday life.

But accessibility does not stop at the lock on the door.

The layout, equipment and condition of the toilet itself still determine whether it is actually usable for an individual Disabled person.

That is why detailed access information matters.
