Learn how to spp

I've raked a few locks but havent found it as reliable as spp'ing(there is plenty of info on this site) . If this lock is in use dont pick it you might end up breaking the lock. Aslo its a good idea to put up a photo.
Ive not come across this lock specifically so i'm not sure what type of security pins it has if it has any at all (without checking google).
