Please respect the concept, if something is not working don't force it call the Cache owner.
The cache works right to left, and the door should pop open when the "ball drops" You must sign the log book to claim a find unless something jambs, then please take a picture, so I know what the issue is. The log book is in the locked ammo can, the combo is behind the door.
The cache door should close with a slight tap, but you may have to reset the lock manually.
Have fun, take your time
