Ok so i bought a kwikset deadbolt to practice with and i can get it fine even if i put mushroom pins in it. i can get my house door i can get my neibors door (of course it was ok with them if i did because i asked before i did anything) but i have two master locks one a 5 and the other a three i got the three to open one but that was it and i cant get the 5 to do anything so is there anything i can do to try and learn padlocks cause it is really frustrating me.
