A ten thousandths pin kit is rarely sold. Lock manufacturers each use specific depth and spacing allowing organized master-key systems to be complex, large, and manageable. A standard pin kit offers the exact size variety needed. Using manufacturer depths permits easy keying, but often you must deviate slightly for optimum accuracy.

Andrews and Newell patented removable tumblers which could be taken apart and scrambled. The keys had bits that were interchangeable, matching varying tumbler

Locks are usually re keyed to build master-key systems, make a set of locks share a common key, or to eliminate compromised keys. Sometimes worn pins are replaced with new pins if the old pins become too short to reach the shear-line. The shear-line is the thin line shared by the

There are some systems, like InstaKey, that allow locks to be rekeyed by inserting and turning a specially designed key without removing cores or lock hardware.
