The RADAR Key, part of the National Key Scheme (NKS), provides people with disabilities and health conditions independent access to over 10,000 locked public toilets across the UK. This large silver key is used by more than 400 local authorities, including the City of York Council, and is found in various public and commercial spaces such as shopping centres, pubs, and airports. Additionally, the “Just Can’t Wait Card” helps individuals request toilet access at certain venues, though it does not guarantee entry.
