A friend pulled out and fired up his Home/School Use Only Karate Champ 2-player cab yesterday for the first time since he moved to a new location several years ago.
Unfortunately he seems to have misplaced the coin door key.

Pretty sure it's the original lock with a flat face (similar to below), number 150.

In case he can't find it, does anyone know a good source for a replacement key?

EDIT: Replaced the lock and left the old one in the coin bucket in case my friend ever does find the misplaced key.
