i cant find the keyhole??

Sorry but your question needs to be clearer, unless there's another part to this question I've missed.

You need to explain what the function of the keyhole is for and what car its on and what button for you mention. That way someone may be able to help.
But in case you don't get replies anyway and its a car phone your local library some do keep vehicle workshop manuals our one in London did. Or sneek a peek in the books in Halsfords.
