RADAR Keys: Accessible Toilets and Where to Buy

By Scott Smith. Last reviewed 13 October 2026.

What Is a RADAR Key?

RADAR was the name of the charity that started the National Key Scheme, which is now run by Disability Rights UK. Councils, pubs, shops, stations, motorway services and other venues fit the scheme’s standard lock to their accessible toilets. The locks keep the toilets free for the people who need them and reduce misuse, while a single key works everywhere the scheme is used.

Who Can Use One?

The scheme is meant for disabled people and others with health conditions who need an accessible toilet, along with their carers. You do not need to prove you are disabled to buy a key from most sellers, though some ask you to confirm you need one. The key is for your own use, so please do not lend it to people who could manage a standard toilet.

Can You Buy RADAR Keys Online?

Yes. Disability Rights UK sells genuine keys directly, and many mobility shops and online sellers stock them. Genuine keys usually have a recognisable shape and often a large fob or loop handle that is easier to grip. Cheap copies sometimes do not turn the lock smoothly or snap in it, which is the last thing you want when you need the toilet urgently. Look for sellers who state the key is made to the National Key Scheme design, and check recent buyer comments for reports of keys that fail.

Some councils also hand out keys for free or at low cost to residents, so it is worth asking at your local council office or library.

How to Find RADAR Key Toilets

Look for the lock with the scheme’s logo on accessible toilet doors. Several apps and online maps list locations, and Disability Rights UK publishes a guide to toilets in the scheme. Train stations, motorway services and large shopping centres usually have one. Keep the key on your main keyring or on a bright lanyard so it is always with you.

RADAR Toilets vs Changing Places

A standard accessible toilet suits many wheelchair users and people who need rails or more room. It does not suit people who need to be hoisted or changed lying down, and for them a Changing Places toilet is essential. These larger rooms have a ceiling hoist, a height-adjustable adult changing bench and space for two carers. Some are locked with a RADAR lock, while others are opened by staff. Our wheelchair accessible bathroom guide explains the facilities in more detail.

Can You Use a RADAR Key Abroad?

The National Key Scheme is a UK system, and you should not expect the key to work in other countries. Much of Europe uses different arrangements, such as the Euroschlüssel scheme in Germany, Austria and Switzerland. If you are travelling, look up the local scheme before you go.

What If the Lock Will Not Turn?

Most problems come from worn or poorly made copies, or from locks that have been damaged or jammed. Push the key fully in before turning, and turn gently in the direction shown on the lock. If it still will not open, try another key if you have one, then ask staff for help and report the fault so it can be fixed. Councils and venues rely on reports from users to know when locks fail. If your own key regularly struggles in different locks, replace it with a genuine one from a reputable seller.

Keeping Your Key Handy

1. Choose a key with a large handle or fob if you have limited grip.
2. Keep it on your main keyring so you do not forget it.
3. Consider a spare in the car or in a bag you always take out.
4. Pair it with a toilet card explaining your need, if that helps you feel confident.
5. Report broken locks to the venue or council so they can be fixed.

The key often sits alongside other help such as a Blue Badge for parking; our Blue Badge guide explains how to apply.

Frequently Asked Questions

Do I Need a Doctor’s Letter to Buy One?

No, not from most sellers. Some ask you to confirm you have a disability or condition that means you need an accessible toilet.

Is the Key VAT Free?

They can be when bought by a disabled person for their own use, if the seller offers VAT relief.

Will a RADAR Key Open Every Accessible Toilet?

No. It opens toilets fitted with the National Key Scheme lock. Some venues use their own locks or keep a key behind the counter.

Can Carers Use the Key?

Yes, when they are with the disabled person they support.

What Should I Do If I Lose My Key?

Buy a replacement from any seller of genuine National Key Scheme keys, as there is no register to report a lost key to. Many people keep a spare in the car or with a carer for exactly this reason. A brightly coloured head or key ring also makes the key easier to find in a bag.
