Different levels of tension on the lock make a big difference in picking. A lot of tension makes the feedback of the lock more clear, but moving the pins precisely hard. Very light tension makes it easy to manipulate the pins but can make it difficult to detect feedback (for example, without accidentally manipulating the pins). In the end it's all about the lock and tension needs to be adjusted depending on the situation. The following exercises are intended to give an initial idea of the range of tension. | |||
===== Minimum tension ===== | |||
# Without tension slide the tip of the pick across the pins from the back to the front, slightly pressing each pin. Notice the spring tension from the pins. | |||
# Apply tension, so light that the tensioner almost falls out of the lock. | |||
## In case of a padlock: Padlocks typically have springs that push the core back to their starting position. If you work with a padlock, check the amount of tension you need to turn the core until it stops turning due to the pins blocking further rotation. Feel how much tension you need to need to rotate the core, just to the point where the core stops rotating when the pins block it but not more tension | |||
# The tension you have should be so little that you just cannot pick with it. Try to move the pick from the back of the lock to the front again, brushing over the pins and feel if you have the same spring tension from the pins. Do you feel a pin that seems like a speed bump in the road compared to the others you brush over? Does it feel more solid? If yes, try to reduce the tension a bit until you can't feel that anymore. | |||
# Now purposely, while brushing with your pick from the back of the lock to the front over the pins many times, minimally increase and decrease the tension. If the tension is such that you feel one pin acting like a speed bump while the other pins don't and you know that if you slightly decrease the tension that speed bump effect is gone, then you found the minimum tension you need to pick this lock. | |||
===== Tension on the binding pin ====== | |||
For this exercise it helps, if you have one, to set your practice lock up with only one pin chamber (only one key pin, driver pin and a spring). Without a practice lock, remember and apply the exercise to the speed bump pin of the previous exercise. | |||
# Tension the lock with the minimal tension that we discovered in the previous exercise. | |||
# Now, while leveraging on the warding of the lock with the back of the pick, feel how little pressure the pick has to provide on the pin to make it move. Release the pressure on both pick and tensioner and repeat this a few times. | |||
# Now apply a bit more tension on the lock and feel again what that does with the pressure from the pick that is needed to move the pin. (Note: don't go to extremes as it can break your pick) | |||
# Try this exercise with lighter and heavier tension. | |||
# Apply heavy tension to the lock and put light pressure on the pick. The pin shouldn't move with this combination. | |||
# Now slowly release tension until, with constant pick pressure, the pin starts to move. Can you alternate tension such that the pin move slowly a little bit, stops with heaver tension and continues to move when the tension is decreased again? How many times can you move and pause the pin until it moved its maximum? | |||

Beginning Pin Tumbler Picking
CommunityLocksThis is where we talk about selecting and sourcing locks for beginning practice. Although there seems to be a lot of people beginning their lockpicking training on padlocks, cheap double euro cylinder can be a better choice; by sawing it in halves, you get two training locks. Gut them (just watch for the skeletonized cores!) and you can progressively pin them to learn your way around the keyway. This also saves you pain of learning security pins right at the beginning - just use standard drivers at the start and start adding security pins into the mix when you are ready.
ToolsTo begin to learn Single Pin Picking (SPP), at least two tools are needed: one to manipulate the pins and one to rotate the lock plug. A pick with a hook profile is often recommended for SPP. It is generally recommended to use a turning tool that fits in the keyway without blocking access to the pins while still providing feedback and control of the rotation. Listed here are a few suppliers where hobby lockpickers frequently buy these tools

ExercisesThe following section provides exercises to help new lock pickers develop their new skills. Like with many other activities, it's recommended to learn good habits from the start instead of unlearning bad habits later. These exercises try to support such a good start. Angling the lock pickThe lock pick often needs to be angled to navigate the lock smoothly. The general idea is that you can move the pick around in the lock without scraping the sides of the pick against the lock, as this can take useful feedback away. This often means the pick needs to be angled clockwise or counterclockwise a few degrees.
Typically the pick requires an angle of 5 or 10 degrees. Also, in general, pins need to be manipulated without disturbing other pins. This generally means the back of the pick should be as far away from the pins as possible, while the tip is able to manipulate one pin at a time.
It is possible that the angles differ by even 90 degrees. Note that the pins in the back of the lock require a significant smaller angle. Feeling where you areWhile lock picking it is generally important to know which pin you are touching and, perhaps more importantly, to know if you are touching a pin. One reason picks break with beginners is that by accident the lock itself is pushed by the pick instead of the pin. An excersise that can help with knowing where you are is the following:
