I know you posted this years ago, hopefully you’ve found more information on them since. I have 4 total in my house we just bought. The main front door does have the original american eagle cover as well, but its the only one set up to have had it, but all are fully in tact. But no one knew the combinations or how to go about using them. I took a couple apart and have gotten one working again but I’m trying to get the rest to work, and I’d like to change the combinations but I cant find anything anywhere with the instructions on how to do so, and I haven’t convinced myself to go against the nice little sticker in it on the cover of the combination area that says both-do not remove the bolts to this cover piece, and do not attempt to change the combination with out the proper instructions- but I think I’m going to have to. 2 of them the dial doesnt sound or feel like its actually moving the pieces inside. does anyone have the instructions on changing the combinations or suggestions on what I should do to fix the dial itself?
