Master Lock Speed Dial
The Master Lock Speed Dial combination lock is quite a departure from the old school number dial combo locks. The way you unlock the Master Lock Speed Dial lock is a series of up / down / left / right movements with the round joystick. Just like the video games of the early 90's. Pretty cool little lock and apparently it is difficult to hack with a shim, although some youngster thinks he has a hack for the Speed Dial, check it out after the break (not sure if it is real or not, seems a tad to easy).
The lock was set to “no-movement” combination, So, when it is cleared (squeezing the shackle)it is in an opening position. When movement is made, the lock is locked.
I think the kid is naive, but his father may be not.
