However, when twisted fast enough I did have great success and having the change dispense correctly. When the quarter did get stuck I had to unscrew the four bolts that held down the mechanism to dislodge it.I do not have a key for it so I did tape the locking mechanism to the inside of the cover so it wont lock accidentally. A locksmith should have no problem figuring out the pin set to be able to make a replacement key. If you have any questions after review of the photos, please feel free to reach out to me.
