My brother-in-law just gave me a gunsafe, it has an S&G combo lock,
3 #'s to unlock, also has a change key with it. He said I should probably change the combination just to be safe, I trust him but he had never changed it since he bought the safe. So, I tried to change the combo , finally did get it changed safely, and it's working fine. However, I'm curious about something. The old combo was: 9-27-68. I cleared the old combo, put in: 10-21-66 and removed key. The lock would unlock on those numbers but when I tried to relock it would jam. The lock lever would go down ok, but when i tried to turn the dial back it would jam. I finally gave up on those numbers and put it another set , staying away from that range and it worked perfectly. I really don't mind, but , like I said , I'm curious. Btw, the lock says r6700 series, and it's splined on 50. Anybody know?Thanks, Rick
