I bought a used Aladdin II slot machine from an auction. I managed to get the key to the door which was locked inside the machine. And I flipped the switch and got it to light up, but that's it. I see a lock on the inside by the hinge and it has a switch next to it. I didn't get a second type of key with the machine, nor a manual. There is a CE code lit up on the front. Please help if you can. Thank you.
