It was perfect in my mind. The only thing that mattered was your characters skills and attributes, not how well the player could manipulate a mini game.
The way I would do it is to remove thresholds entirely and let anyone try any lock with any skill, however if you fail the lock jams. This would allow the setting up of extremely hard locks in order to limit access to something really valuable. Sure, you could try to get it with a skill of, say, 40, but you're almost certainly not going to.
Failure would mean either getting the wrong location with the bobby pin or the wrong password, and increasing one's skill would increase the chance for the chosen position or password to be correct. Basically, I would restore the character's skill as the determining factor.
