There are some lock just about the one you have. I use what they call Shim if you can get it inside of the cylinder than pull out and be sure hold on to the shim. If not have to take it out slow one by one so the spring will not pop out. To put back in use the shim on top of the hole where the spring are and slowing push the cylinder back in. Hoping this would help out and maybe someone else may help. Not sure as I know you have information from another forum which not a member of them. Maybe they can explain better of what I said. I do know Jeffmoss26 member other forum maybe can help out more......Timothy....
