ghostlight, unfortunatly I’m afraid your probably out of luck. There are a lot of different combos ,3,4,5 digit ,RLR,RLRL,RLRLR and LRL,LRLR,LRLRL. Some start from zero,some start from dead stop left,or dead stop right. I’m thinking your brother has your lock(hence the reason you remember the combo) and you have his. I’de try to talk him out of it if it was me🙁giggle):. Good luck, Mark
