Try opening door--turn reset key--close door.
If that doesn't work check battery.

do you mean the quarter size battery?

A couple things to check (Power off)
Locate the door I/O board mounted at an angle on the left end of door below the VFD but is not the VFD driver.
The VFD driver has white plastic cover.
The I/O board is on the front of that panel behind the VFD driver, if you machine has the older VFD display.
You will want to carefully pull the I/O board up about 1 inch and reseat it. Also locate the Cabinet i/O boad and do the same (its mounted to the side of the MPU cover.
How you know you found the I/O boards they have a flat metal handle on them.
The door I/O board will have a connector plugged into the molex near the handle.
The Cabinet I/O may or may not have something plugged into the connector at the handle.

Foster The door I/O doesn't allways have a flat metal handle. I have two machines that both have the 10 button play deck, both of these machines have two door I/O's and both are the Black plastic.  I don't think they will interchange with the metal ones.
