i'm started lock picking few years back just for fun and recently came across my lock picking set again and thought that i might continue my hobby to improve.
i'm able to open simple wafer locks that i tried. however, i'm having trouble with this lock.
upon releasing the tension wrench, i can hear few clicks but no matter how hard i try to pick, it just wouldn't open.
can anyone tell me whats wrong ? and what lock is this considered as ?
also, im using a southord set and picking this lock with a half-diamond pick.


pardon my ignorance.
thank,
mark
