Picking euro cylinder

[minifhncc]

Hello,

When I used a pick gun to pick a euro cylinder today to change its pins I encountered something quite unusual.

When I initially picked it in the anti clockwise direction it turned with quite a bit of resistance. I stopped turning it until it was turned about 90 degrees in fear that I might break something.

Then I picked it in the other direction, and it turned without any problems (ie. no resistance).

The exact same thing occurred with the other keyhole.

I suspect that one or more of the springs may've become caught in the bottom pin holes. But how could this had occurred?

I had changed this lock once before, without knowing what top pins were used. A possible reasoning is that I changed a pin that used to be longer to a shorter one, and now the stack height is too short.

But if this was the case then why did picking it in the other direction (for both key holes) avoid this problem?

Thanks

This may seem a dumb question, but is the cylinder installed in a door or in a lock? Maybe the problem is not the cylinder itself but something which it interacts with.

I took the cylinder out of the lock to rekey it.

It was not attached to anything and had its cams removed when I picked it.

Sorry, I had to ask... Looks strange to me, maybe the wrench frictions the inner wall of the cylinder while turning one direction? I have no other ideas. Let us know what you find out if you manage to solve this little issue.

Good luck

My initial thought was that, sometimes the angle and position of the tool in the lock causes friction. If it was a spring I'm sure you would have seen cuts in the pin chamber if not seen an actual bent spring when you re-pinned it.
