Ok, so there is a room on our floor that the school locked since no one is using it(im currently in college). We are attempting to get it open it for a lobby room...
anyways we have compared our keys and all of our keys are very simialar. i didnt know if there was a way to make a master key, and what it possible could look like, i know that they are using best cylinders and our keys have a J stamped on all of them and i think they are for 6 pin locks... is there a guide or more information out there for these keys?
thanks
