Pro Pick Lock

The Pro-Pick has the ability to open padlocks with the M1, AM3, or M12 keyways.  Pictured below are just some of the various types and brands of locks that use these popular keyways.  It is important to note the following, and why the keyway silhouettes should be the primary indicator for application and functionality

  • Lock and key blank companies that utilize these same keyways may call them by different names or part number
  • Locks with interchangeable cylinders can be fit with multiple types of keyways
  • Additionally, some foreign locks may also use similar keyways, though have alternate interior pin dimensions.  Keys to these more popular foreign locks are currently under development and will be offered in the future as add-ons to the Pro-Pick kit.
