Master Lock 150

Difficulty Notes

The Master Lock 150 is considered a step up from the 140 but easier than the 1100. It offers more of a challenge than better-manufactured locks due to poor construction/durability. It is described as the 'Gary' to the 'Ash' (implying a significant but manageable hurdle for new pickers).

Picking Notes

SPP (Single Pin Picking) is implied as the primary method for beginners; raking is advised against for beginners due to bending thinner picks. Tension should be applied at the top of the keyway, preferably using a prybar.

- u/frickdom (5pts): 'I'd skip the rakes though.'

Bitting Variance

Manufacturing variations exist regarding construction and durability, often resulting in poor quality compared to other locks. The pin spacing can be tight, especially when transitioning from standard pin tumblers to wafer locks (though the 150 is a pin tumbler, the comment regarding tight spacing is noted in the context of learning progression).
