I have a pachislo slot machine and it has 3 key holes…1 at top right to open main door & service door a second one to reset machine inside lower left… and now for the baffling one…there is a keyhole right side under coin slot that one has 3 wires coming off it and the main door key makes it turn left and right but I cant tell what it does. Any suggestions ? ---

Since the OP wants advice/opinions, it doesn’t belong in ATMB. Moved to IMHO. samclem, moderator ---

There is a keyhole under the coin slot with three wires coming out of it? It would help if you have a picture of what you’re talking about along with the make and model of machine. I have an inkling that the wires are supposed to connect to a cylinder lock that electronically detects whether the machine is being tampered with, but I have never heard of them being located right by the coin slot.
