Mephisto Pachislo Style Token Japanese Slot Machine Yamasa Co. - No Key As Is

Description

Sold as is.
It powers on, lights and sound work but it has an E4 error message.  A google search says that it has something to do with the hopper and is usually an easy fix but I do not have the key.  The lock might not be the original, it looks different from others I've seen online.  I don't know how much work this will need to be operable again.
It is SUPER LOUD when first plugged in, after about 5 minutes the volume automatically lowers.
It's in good condition, just some light cosmetic wear from normal use, see photos for condition.
Local Pickup Only.
