This is a two pack sampler: One each of our pair of sidewinders. When you bend the tabs (see picture) into your required direction, the tapered nose of the 0.004" thick shims will lift the lock's pins or wafers up out of the way allowing the bent finger to enter the key cut.

With the pins lifted up and the finger woven into the key cut, there is nothing left to do but pull the key out! Works best on pin tumbler cylinders.

You get the pair (one of each) in a plastic tube.
