I'm trying since last week to open a CISA with 4 pins with no success. I bought 3 DVDs and 2 manuals about lock picking and I understood a lot, but I still can't get any results. I also got problem when I try to put the hook inside the lock due to the way the cisa is made. I don't know. If you have any suggestion please let me know. Here is the cisa.
