Unable to pick tubular lock with HUK set
In the meantime I wonder if I'm doing something wrong, its embarrassing all the tutorial videos make it seem so easy. I spent hours trying different number of rubberbands on the tool and the fingers look like they are keying right but no sign of the lock budging. It appears to be a regular old tubular size 7.8 lock with 7 pins, it also has a number marking in front that says s877 which I have no clue what it means. Any tips on this, if its not opening easy with the tool am I just wasting my time? Also is there any place I can order a known susceptible tubular lock that I can practice on with the HUK keys? I see theres a bunch on amazon, not sure which is a good option to practice on for a newbie like myself!
Thanks!
