Kwiket Bottom Master Lock Pins

Rekeying a Kwikset cylinder means changing the bottom pins in the plug so that a different key lifts the stack to the shear line. Master pins are the extra wafers that let a second key work the same lock, which is how a master keyed system is built.

Pin sizes and depth increments are specific to the system, so a Kwikset pin is not a Schlage pin. Check the system and the number of chambers before ordering, and keep a few of each size spare.
