Schlage Rekeying Guide

Schlage Rekeying Guide

Schlage is one of the most recognized Lock Brands in the USA Today. Schlage is unique though. Most Lock Manufacturers are known for great residential locks (like Kwikset) or great commercial locks (like Sargent) but it is rare for a lock manufacturer to be known for great, high quality residential and commercial locks. But it goes even further, Schlage is also the most knocked-off commercial lock brand in the industry today! Just about every “good” aftermarket or imported lockset uses a very similar if not exact design. To this day, Schlage sets the standards on what a good lock looks and feels like. So, if you are in the Locksmithing Industry you will run into Schlage or Schlage knock-offs on a normal basis.

Quick Jump:

Before we go to deep I want to provide a quick history lesson...

Walter Schlage - History of Schlage Locks

Schlage Locks History

Walter Schlage was a mechanical engineer by trade. He was born in Germany but immigrated to the United States during the early 1900s. After leaving his job at Western Electric Company, Schlage opened up his own lock shop in San Francisco. The company was officially incorporated. A century later, it’s now one of the most recognized trademarks in the United States. Schlage Locks are centered on style and convenience which in my opinion has made Schlage a household name, staying up to date on current design trends at the same time making the locks easy to install and use.

Go even deeper in the History of Schlage.

Schlage Rekeying

Since Schlage makes both residential and commercial locksets, I am going to break them down separately although they share many similarities the differences are important to point out. As I pointed our above, since Schlage’s design is knocked off so much the information here will also apply to all locks that are using the Schlage Design. The good news is the tools and pinning kit needed to rekey the Schlage Locks are the same for residential and commercial!

Schlage Lock Pinning Specifications:

  • Depths: 0-9
  • Bottom Pin #’s: 0-9
  • Master Pin #’s: 2-9
  • Top Pin #’s: 1-3
  • Plug Diameter: .500”

LockVoy Rekeying Kit

Schlage Rekeying Kit’s and Tools.

I recommend 3 Types of kits that are available to rekey Schlage Locks.

The Starter (compact kit)

A small compact plastic kit, made by LockVoy. This kit is perfect for basic residential or commercial Schlage Lock rekeying, it even comes with the tools needed to rekey Schlage Locks. The downside is that it only has the #2 Schlage Master Pin, so you can do some very basic master keying and is most used for Schlage residential lock rekeying.

The Heavy Duty Professional Kit (lasts a lifetime)

The other recommended kit is this heavy duty, metal case rekeying kit. It has all of the Schlage Pins and is built to last a lifetime. If you plan to rekey Schlage locks for the next decade, then this kit is the way to go!

The Universal Kit (.003)

A .003 Universal Pinning Kit has every Schlage pin plus much more. In this one kit you can rekey Schlage Locks, Kwikset Locks, Weiser Locks, Sargent Locks, plus many more! One other benefit is that the pin sizes go up by .003 (for example .240”, .243”, .246”, .249”) this allows you to work with old, warn down keys.

Rekeying Schlage Residential Locks

Most Schlage residential levers and knobs are known as F-Series and will have a C clip on the back of the plug you will have to remove to rekey them. They also have what is known as a compressible cap, this cap makes it very simple to remove the cylinder from the lock housing however it is very problematic, and you will want to take great care with it. Many, when new to rekeying want to “pop” off the cap to rekey it from the top of the cylinder, this is a mistake as it wears down the part of the cap that holds it on and will lead to future issues down the road. Residential deadbolts are pretty simple to rekey and are very similar to Schlage Commercial Deadbolts, you just need to take of the back cylinder cap to take apart and rekey.

A word on master keying Schlage Locks with a compressible cap...

It is possible, but it is not recommended as the cap will pop off eventually. If you must only use a 2 step system and add master pins as sparingly as possible and try to even out where they go in. For example, put a master pin in the #1 chamber and #5 Chamber. Don’t put master pins in #1,#2,#3 chambers, spacing them out is your best option. Also, make sure you have extra t-pins (top pins) and springs to match the t-pins.


Rekeying Schlage Commercial Locks

Schlage Commercial Locks are some of the easiest locks to rekey once you have the lock plug out of the lockset. Simple remove the clip or cylinder screw cap off the back and rekey. Schlage Commercial Locks are also great locks to master key.

I hope this information not only answered any questions you had about rekeying Schlage Locks but also gave you some additional information to make sure you are prepared for Schlage Commercial and Residential Locks.
