the machine needs to have the door switches made,(or closed)because it isolates the meters and payouts with the door open and also it is saying invalid key because it has the wrong price of play key in or if the stakes and prizes key is switchable it is set wrong

[ben twilly]

sounds like to me pretty much what lee said. more than likely a screwed door switch, and wrong percentage/stake key. or have you been mucking about with an adjustable stake/prize key?
