Cruciform tubular lock?
Anyone know what to call this thing?
It is similar to a tubular lock in that you have to push down pins to a correct depth before the lock will turn.
I tried picking it but once you set 3 of the pins the tension is so strong on the last pin that it gets locked up. I try releasing some tension, but that usually unsets everything else. I am still working on it. I am not sure if a special tool is required.
