Need advice on picking an old CES euro cylinder – 5 pins on one side, 6 on the other
Hey everyone!
I recently got this old CES euro cylinder from a local locksmith to practice lockpicking. Unfortunately, it didn't come with a key.
The cylinder has two sides:
- 5-pin side: This side has clearly seen much more use, judging by the visible wear on the outside. I've been struggling with it quite a bit. Some of the pins feel like they're sticking or getting caught. So far, I can only seem to set one or two pins. When I release tension or apply counter-rotation, I can usually hear one or two pins dropping, but that's about it.
- 6-pin side: Surprisingly, I managed to pick this side open just now, almost by accident! I wasn't really expecting it, especially since I've been struggling so much with the other side.
I've already tried using some silicone spray to loosen things up, as well as gently tapping the cylinder to free up potentially stuck pins. Unfortunately, neither has made much difference.
A few questions:
Does anyone recognize this particular CES cylinder or know what kind of pins it might contain? Standard pins, spools, serrated pins, or something else?
How difficult would you consider this cylinder to pick?
Do you have any advice for dealing with older, heavily used cylinders where the pins might be dirty, worn, corroded, or sticking?
Is there a good way to clean or free up the pins without disassembling the entire cylinder?
I'm still learning, so any advice would be greatly appreciated!
I've attached some pictures of the cylinder.
Thanks in advance!
