Sparrows Core Shims

The attack is simple wedge the shim over the core and slide it back until it stops.
The object that is stopping it is the top pin of the first pin stack.

With your pick slowly raise up that first pin until the shim finds and slide through the gap between the top and bottom pin.
The shim will now hit the second pin stack …. repeat above…. you get the idea you want to list the pin stacks and keep moving the shim back until it has covered the sheer line.

With the sheer line covered insert your tension wrench and open the lock.

It comes in 3 different sizes, 10 of each.

Some finer tips

  • You will not need a tension wrench until the very end to open the lock.
  • If the shim slide between the Core and the lock frame odds are good this will work.
  • If you can touch the first pin with a straight shim this bypass will work.
  • Handles for shims ….. they exist but it is easier to work these without one
  • This is pretty easy to do and has a very high “that’s neat” factor.
