Difficulty Notes

Newer models generally have security pins; older ones do not. The 570/575/576 series has a dead core. It is considered a good beginner lock for those with security pins if they have no false sets, but tolerances can be poor.

Sources (r/lockpicking):
- u/davidromano67 (2pts): 'It's kind of a crapshoot, generally speaking the newer ones have security pins and the older ones don't.'
- u/bluescoobywagon (1pts): '...Master 570/575/576 (which has a dead core).'
- u/LockPickingFisherman (1pts): 'This one will have no false sets and should be difficult but still accessible to a beginner'

Picking Notes

City rake is destructive on locks with security pins and poor tolerances. Genesis picks are thinner and less flexy than standard picks.

Sources (r/lockpicking):
- u/davidromano67 (2pts): 'I find the city rake to be an absolute destroyer of worlds when it comes to locks with security pins and poor tolerances or lousy bitting.'
- u/LockPickingFisherman (2pts): 'I suspect your luck will improve with the Genesis picks. They're probably more refined and definitely thinner and less flexy.'

Bitting Variance

Manufacturing variations exist between older and newer stock (older lack security pins, newer have them). The 570/575/576 series shares the same core as the Master 605. The 570/575/576 series uses the W81 keyway. Some users note that clicks can be misleading as they may result from the pick slipping off warding rather than a pin setting.
