Keys and cuffs compatible?

I do this search on ebay uk:https://www.ebay.co.uk/sch/i.html?_from ... s&_sacat=0

Two people selling some high security handcuffs but also 2 keys show from the resulting list. Are these two keys a high security key for the same handcuffs shown in the search?

please give us an exact item to look at, not just a search list
