Bally E-1096-10-79 Please help

[Oddzball]

Hi, I'm new here. I have never owned a slot machine or pinball machine before, but always wanted one. Had the opportunity to pick up what I think according to the plate is a Bally E-1096

I bought it cheap because the guy didn't have the keys and i would put coins in and it wouldn't register that a coin was inserted.

So yeah, I have absolutely no idea whats going on, I opened it up, looked at everything. I dont see anything broken. There are two keys. on on the side under the arm which im not sure if that "locks" the machine maybe? And then the front one which opens it up.

SO i put coins in, doest register (They come right out the bottom, most of the time) and I cant pull the lever.

Pretty please help? I got this as a gift for my wife. She loves slots, and I figure this is cheaper then dumping money in a casino machine.

Thanks.
