Master Lock 130

Difficulty Notes

The Master Lock 130 and 140 are classified as 'Yellow Belt' locks. They are described as 'trivially easy' compared to a Sparrows revolver. One user noted the Master Lock #3 was harder than the 130 due to bitting. The 130/140 are considered good for beginners to get a 'quick satisfying pop'. The 150 is noted as having one lever higher (Orange Belt).

Picking Notes

SPP (Single Pin Picking) is mentioned as a technique to learn on acrylic locks. Raking with a 'snake rake' via rocking is noted as a method that works but takes time. Bypassing is possible by retracting the locking lever (specifically for the 121, but context implies general padlock mechanics).

Sources (r/lockpicking):
- u/Bodhisattva_Picking (2pts): '...identifying correctly whether not not you're moving one pinstack or multiple. This is greatly important for SPP.'
- u/throwawaytnt (3pts): 'You can rake them open with a snake rake via rocking, but that can take a while...'
- u/JosephFaolan (2pts): 'To bypass, you can retract the locking lever.' (Context: 121, but relevant to padlock bypass mechanics discussed in thread)

Tension Tips

For acrylic practice locks, users advise to 'disregard your tension entirely' initially to focus on pin feel. For real locks, users emphasize learning 'how much tension is needed' and the 'feel' of the tension.

Sources (r/lockpicking):
- u/Bodhisattva_Picking (2pts): 'When you're using it [acrylic lock], disregard your tension entirely and just use your pick to really get a feel for each pinstack...'
- u/Evl_Stache (5pts): '...learn the feel of how much tension is needed and what you feeling'

Bitting Variance

Acrylic/clear locks are noted to have poor tolerances compared to real locks, making them feel inaccurate despite showing pin movement. The Master Lock 130/140 are widely recommended as starting points. The Master Lock #3 is noted for having super tiny keyways and being difficult to pick despite being easy to rake. The Master Lock 150 is a step up (Orange Belt) due to an additional lever. Some users mention finding rusty or unknown locks in garages that were harder than expected.
