glad to help. not sure what you got going on but if you are dealing with the ones with the chrome rectangular cover and you just want to rekey em you can take it off (bend the tabs just enough to it will come off as they are brittle) & mix/match pins/tumblers to match a different key as needed if you have some spare cyls to play with or clean one up if it is sticky. you want the "heights" the same so the barrel will turn in the cyl with the key installed.
