RADAR Key Guide
National Key Scheme — UK accessible toilets
One small key unlocks more than 10,000 accessible toilets across the UK. Here's what it is, who can get one, and where to buy a genuine RADAR key for around £5.
What is it?
The RADAR key (officially the National Key Scheme, or NKS) unlocks over 10,000 accessible toilets across the UK — in shopping centres, train stations, motorway services, council buildings and more. The single key fits all NKS-compliant locks, so you only ever need to carry one.
Who can use one?
Anyone with a disability, long-term illness or condition that means they need access to an accessible toilet. There is no formal qualifying process — buying a key is on a self-declaration basis, and most suppliers sell them VAT-free if you have a relevant condition.
Where to buy a genuine RADAR key
The official source is Disability Rights UK, the charity that administers the scheme. Keys are also widely available from major pharmacies (Boots, Lloyds), Amazon, eBay, and disability-focused retailers. Expect to pay around £5 for a genuine key — be wary of suspiciously cheap counterfeit keys that may not fit every lock.
How to spot a RADAR-locked toilet
Look for a small round keyhole on or beside the door of an accessible cubicle, often with a "National Key Scheme" or "RADAR" plaque nearby. In the Where To Wee app and website, any listing tagged "RADAR Key Required" needs your key — we surface this on every toilet card so you can plan ahead.

Frequently asked questions
How much does a RADAR key cost?
A genuine RADAR key costs around £5 from the official supplier (Disability Rights UK), with VAT relief available if you have a qualifying condition. High-street pharmacies sell them for a similar price.
Where can I use my RADAR key?
The key opens any toilet that has been fitted with an NKS-compliant lock — over 10,000 toilets across the UK. This includes facilities in shopping centres, train stations, motorway services, council buildings, parks, and some private venues.
Do I need proof of disability to buy a RADAR key?
No. Keys are sold on a self-declaration basis. To claim VAT relief, suppliers will ask you to confirm a qualifying condition.
Can I buy a RADAR key on Amazon?
Yes, but be cautious — there are counterfeit keys on Amazon that don't fit every NKS lock. The official Disability Rights UK key is your safest bet for a guaranteed working key.
What if a RADAR-locked toilet is broken or dirty?
Report it to the venue or council that operates the toilet. You can also flag the listing in Where To Wee so other users know about the issue.
