Patent-Protected Key Systems for 2020 and Beyond

An Introduction to Key Control 

In a perfect world we would never have to worry about lost keys or keys falling into the wrong hands. Unfortunately, we do not live in a perfect world, we live in the real world. The real world requires us to account for these scenarios if we wish to protect and maintain key systems. We account for these scenarios by practicing key control via patent-protected key systems.
Key control, as defined by Wikipedia, refers to various methods for making sure that certain keys are only used by authorized people. Perhaps the most important method, and the cornerstone to all effective key control, is the key control policy. Key control policies set forth rules and procedures for key systems. They generally cover areas such as the roles and responsibilities for those involved with the key system, key requests and issuance, record keeping and auditing, and maintenance tasks, such as rekeying. When done correctly a key control policy is the blueprint to successful key control. More important, successful key control protects a building, or buildings, and its occupants.

Patent-Protected Key Systems and Key Control

A key control policy’s effectiveness is greatly enhanced with a patent-protected key system. Via utility patents, the sale and distribution of key blanks carries federal law protection. This means protection against the unauthorized duplication of keys. Think about the implications of this from both sides, the locksmith and the end-user. The locksmith is able to offer a key that cannot be duplicated anywhere else and the end-user has the peace of mind that their keys cannot be duplicated without their authorization.  
Multiple factors come into consideration when selecting patent-protected key systems to offer to end-users. Things like buy-ins, annual minimum purchases, required servicing equipment, and availability must be evaluated. Rather than steer you in one direction I will simply present you with options. 
Before I begin discussing said options, I want to point out one very important factor of patent-protected key systems: each new calendar year means their utility patent is either expiring or is one year closer to expiring. While no patent-protected key systems are expiring this year, 2021 will mark the end of patent protection for Medeco’s M3 and Sargent’s XC platforms, barring no extensions. In 2022 and 2023 the same can be said for Arrow’s CHOicE and Kaba’s Peaks Global, respectively. With this in mind I have not included these platforms in the following list due to their shorter patent lives 

Patent-Protected Key Systems

Abloy Protec2

Abloy Protec2

Abloy Protec2


Abloy’s Protec2 platform is the latest in a long line disc-detainer designs that made Abloy famous. 11 discs within each cylinder allow for 1.97 billion theoretical key combinations and incredible pick resistance. While disc-detainer designs are known to rugged, Abloy took things a step further by incorporating its patented Anti Wear System (AWS) to prolong each cylinder’s life. Abloy also incorporated an interactive element into each key for added protection. The Protec2 platform is able to be integrated with CLIQ and its patent expires in 2031. 

BEST CORMAX 

BEST CORMAX

BEST CORMAX


Based on the SFIC format that BEST pioneered, CORMAX utilizes a patented side pin that engages a special slot at the tip of each key. With dozens of keyways broken into two different keyway families, or Series, CORMAX provides an upgrade path for existing BEST standard and MX8 keyways. Multi-milled keys are also available to create large master keying possibilities.  The BEST CORMAX patent expires in 2027. 

Corbin Russwin Access 3 

"<yoastmark
Corbin Russwin’s Access 3 is actually 3 key platforms, each offering their own benefits and price point. AP, or the first level protection, offers key control. AS, the second level of protection, offers key control and additional bump and pick resistance. AHS, the third level of protection, adds drill protection onto the AS and comes with a UL437 certification. Each level is priced differently to assist with providing a solution at any price point. Access 3 is available to fit all existing Corbin Russwin cylinder types, including Corbin Russwin LFIC, and offers integrability with CLIQ. Its patent expires in 2027. 

Kaba Peaks Preferred 

Kaba Peaks Preferred

Kaba Peaks Preferred


Kaba’s Peaks Preferred uses a patented “Peaks pin” that interacts with a hollow milled key. This design is able to be configured into almost any cylinder or core format currently on the market. Peaks Preferred keys are able to be originated using most existing key machines. The Peaks Preferred patent expires in 2024. 

Medeco X4

Medeco X4

Medeco X4


Medeco’s X4 platform is the patented successor to the Medeco Keymark. As was the case with Keymark, X4 offers economic and efficient key control by offering cylinders and cores available to retrofit into almost any existing door hardware under a single keying system. Last year, Medeco was able to secure a 3 year extension to the X4 patent meaning that it will remain protected until 2030. 

Mul-T-Lock Integrator 

Mul-T-Lock Integrator

Mul-T-Lock Integrator


Mul-T-Lock’s Integrator platform builds on their 7X7 platform with enhanced tamper resistance and flexible master keying possibilities. It utilizes a 7-pin cylinder design that interacts with a patented key blank which uses an oval cut in 3 different configurations: internal, external, and twin. The Integrator is able to utilize Mul-T-Lock’s 3-in-1 keying option which allows you to rekey a cylinder up to 2 times by simply turning the key The Integrator patent expires in 2024. 

Mul-T-Lock Interactive+ 

Mul-T-Lock Interactive+

Mul-T-Lock Interactive+


Mul-T-Lock’s Interactive+ is the successor to the original Interactive platform. Using an interactive element on the key blade as well as a pin-in-pin dimple design, the Interactive+ platform is able to provide keys that are backwards compatible and will work with equivalent Interactive cylinders. The Interactive+ is able to utilize Mul-T-Lock’s 3-in-1 keying option which allows you to rekey a cylinder up to 2 times by simply turning the key. Interactive+ offers integrability with CLIQ and its patent expires in 2025. 

Mul-T-Lock MT5+ 

Mul-T-Lock MT5+

Mul-T-Lock MT5+


The MT5+ takes Mul-T-Lock’s traditional pin-in-pin design and adds finger pins that interact with a sidebar as well as an interactive element at the tip of the key. This design provides multiple layers of security and robust master keying possibilities. The MT5+ is able to utilize Mul-T-Lock’s 3-in-1 keying option which allows you to rekey a cylinder up to 2 times by simply turning the key. MT5+ offers integrability with CLIQ and its patent expires in 2025. 

Sargent Degree 

Sargent Degree CLIQ

Sargent Degree CLIQ


Sargent’s Degree platform is very similar to Corbin Russwin’s Access 3. Degree Level 1, or DG1, offers key control, Degree Level 2, or DG2, offers key control and additional bump and pick resistance, Degree Level 3, or DG3, adds drill protection onto DG2 and comes with a UL437 certification. Each level is priced differently to assist with providing a solution at any price point. Degree is available in mortise, rim, and KIK/KIL cylinder formats as well as Sargent’s 6300 LFIC format and offers integrability with CLIQ. Sargent Degree’s patent expires in 2027. 

Schlage Everest 29 

Schlage Everest 29

Schlage Everest 29


Schlage’s Everest 29 platform is the successor to the original Everest platform. In fact, Everest 29 keyways are backwards compatible with their Everest equivalent. Like the Everest, the Everest 29 utilizes a check pin that interfaces with an undercut groove on the key. You can duplicate and originate Everest 29 keys on any machine capable of cutting Schlage Classic keys. The Everest 29 patent expires in 2029. 

Schlage Primus XP 

Schlage Primus XP

Schlage Primus XP


Schlage’s Primus XP builds on the original Primus platform by adding a 7th finger pin position. Primus XP adds tremendous flexibility because it is compatible with all current and many legacy Schlage keyways, including Everest and Primus keyways. Like Everest 29, you can duplicate and originate Primus XP keys on any machine capable of cutting Schlage Classic keys. The Primus XP patent expires in 2024. If applied to an Everest 29 based key system, the Everest 29’s patent protection overrides the Primus XP patents for protection until 2029. 

Patent-Protection and Profit 

If you do not offer patented-protected key systems for your customers to assist with key control, now is the time. It’s a win-win for both sides. Patent-protected key systems are not only valuable from a security standpoint, they’re valuable to your bottom line. Selling and servicing patent-protected key systems creates a steady stream of income since the end-user is locked into your keyway(s). They have to come to you to service the system. Furthermore, it protects your accounts because your competition cannot obtain the materials necessary to service your accounts. Finally, there is tremendous profit. Patented cores/cylinders often times list for at least 4-5 times more than their generic counterpart. If your discount is less 50 on both, for example, it’s easy to see the substantial profit margins. To learn more about patent-protected key systems, please contact your local rep(s) or visit our High Security Library page.

Corbin Russwin Access 3 Pinning Worksheets Added to Tools

We have added two new worksheets to our Pinning and Decoding Worksheets Tool. Both worksheets are for Corbin Russwin’s Access 3 platform.
The first worksheet is a pinning worksheet for Corbin Russwin Access 3 conventional cylinders. This worksheet contains a pinning chart and combinating rules for Access 3 KIK/KIL, mortise, and rim cylinders.
The second worksheet is a pinning worksheet for Corbin Russwin Access 3 large format interchangeable cores (LFIC). This worksheet contains a pinning chart and combinating rules for Access 3 large format interchangeable cores.
The Access 3 is still a relatively new platform, debuting sometime between 2013-2014.  It is analogous to the Sargent Degree platform, in fact, they’re practically identical. For more information, see the Access 3 Technical Manual in our Library.

Peaks Authentic YouTube Channel Launched

Last month Ilco launched their Peaks Authentic YouTube channel. This channel features a growing collection of servicing videos related to Peaks Preferred products.

Creating Pinning Charts for Sargent Degree Cores and Cylinders

Design

The Sargent Degree key system is actually comprised of 3 sub-systems:

  • Degree Level 1
  • Degree Level 2
  • Degree Level 3

Degree Level 1, or DG1, utilizes a patented keyway with conical pins. If you are at all familiar with the Medeco3 BiLevel platform that is essentially what DG1 is.
Degree Level 2, or DG2, utilizes a patented keyway with angled pins that then interface with a sidebar. Furthermore, each key features a “notch” to interface with slider that, again, interfaces with a sidebar. If you are at all familiar with the Medeco3 platform, that is essentially what DG2 is with one exception: there are only 3 labeled pin angles (Left, Center, or Right) and there are no fore/aft positions on the key.

An exploded view of a Sargent DG2 LFIC.


Degree Level 3, or DG3, is DG2 with a UL437 certification.
If you are at all curious of the influence of Medeco designs with the Degree key system, there is a good reason: the cylinders utilize existing Medeco patents (Sargent and Medeco are sister companies under the ASSA ABLOY umbrella).


Pinning Considerations

Sargent sells two pin kits related to the Degree key systems:

  • 437 DG1 Standard Pinning Kit
  • 437 DGM Master Pinning Kit

The 437 DG1 Standard Pinning Kit services DG1 conventional cylinders and LFICs. The 437 DGM Master Pinning Kit allows you to service DG1, DG2, and DG3 conventional cylinders and LFICs. Replacement pins, springs, and covers are all available through Sargent distribution channels

Large Format Interchangeable Cores (LFICs)

Much like the traditional Sargent 6300 LFIC, Degree LFICs utilize two different stack height values: 10 for non-control chambers (chambers 1, 2, 5, 6) and 13 for control chambers (chambers 3 and 4).
Additionally, DG2 and DG3 key sub-systems must utilize a conical pin in the 6th position of LFICs. Due to the physical size limitations of the Degree LFIC, which is essentially the same form factor as the traditional Sargent 6300, there is not enough material left in the core to mill the indicator slot for angled pins. Do not attempt to force an angled pin into this position as it will eventually cause operational problems. This requirement does not impact keys, specifically what angles or depths to use in the 6th position, or vice versa.

Conventional Cylinders

Unlike the previously mentioned Medeco designs/systems, Sargent Degree conventional cylinders do not utilize top pins that match the numeric value of the deepest cut in each respective chamber. For example, in a Medeco Original cylinder with a 4 cut in the 1st chamber, the locksmith must utilize a 4 top pin. With Sargent Degree, the plug total must always equal 10 for conventional cylinders. So, if we have a 4 cut used in the 1st chamber of a Sargent Degree conventional cylinder, our top pin must be 6 (4+6 = 10). In master keyed cylinders and chambers, bottom and master pins (plug total) are added together and subtracted from 10 to determine the top pin. Here is a pinning chart example for a master keyed, Sargent Degree conventional cylinder:

Construction Master Keying

Construction master keying is available for all Degree platforms by using the “lost wafer” design. Similar to a “lost ball” design, a Sargent Degree plugs with the appropriate cylinder option contain a “donut” hole to the left and right of the 3rd chamber. This hole captures a special wafer through typical construction keying change/protocol. As you can see in the illustration below, this design is in place so that only these special wafers can become trapped in the plug.

Sargent Degree cylinders, except hotel function cylinders and LFICs, use the “21 -” option for construction master keying capabilities. LFICs use the “64-DG-” option.

Pinning Chart Tools

We have 4 tools available to assist you with creating pinning charts for Sargent Degree LFICs:
First, we have Sargent’s Degree Key System Technical Manual.
Second, we have two Sargent Degree pinning worksheets on our Pinning and Decoding Worksheets page. One is for 6300/LFICs and the other is for conventional cylinders..
Finally, we have 2 key bitting specifications; one for the DG1 sub-system and one for the DG2/DG3 sub-system.

Medeco Turns 50

On Saturday, Medeco celebrated 50 years in business with a large party at their Salem, Virginia headquarters. I was lucky enough to be there.


Before I discuss the celebration, let me stress how beautiful of a place Salem and the Roanoke Valley is. I took these pictures from Medeco’s parking lot. You would be hard-pressed to find a more picturesque place to live and work.


Hundreds of employees (past and present), their families, customers, vendors, and others in the community attended. There was plenty of food, drinks, games, music, and fun.



There were even keepsakes and souvenirs for the occasion.


Medeco provided factory tours throughout the afternoon. I was fortunate enough to take a tour of the facility. Truthfully, this was the part of the trip I was probably most excited about. No cameras were allowed, for obvious reasons, but I’ll do my best to relay what it’s like while respecting their privacy. I believe I heard, and I may be wrong, that the facility is 132,000 square feet and employs  around 180 people. Suffice to say, it’s a very big facility. When you think of a manufacturing facility things like automation and assembly lines come to mind but with the exception of a few robotics, Medeco’s facility is largely hands on.
There are dozens and dozens of milling and CNC machines, lathes, presses, and then some! Some of the equipment looks like it’s been there since the beginning of Medeco’s journey in 1968, maybe even before then, and some of it looks like it showed up just a week before. They’ve found a way to stick with what works while embracing innovation to succeed. Even more incredible is that it seems that they do just about everything from scratch. They make their own tools, their own prototypes, heck they even make their own machines. If you knew nothing about Medeco and walked into the building blindfolded, you would swear you were inside a machinists’ paradise – in a palace of precision.
In front of a lot of the equipment, I saw piles of brass stock neatly organized. The machines took this stock and made just about every single component and piece of a Medeco key, cylinder, or lock. I saw the machines that make the pins, the machines that make the sidebars, machines that broach keyways into plugs. Machines everywhere, each with a unique purpose.
I particularly enjoyed their plating room. I think we’re all familiar with finished products, pardon the pun. We’re used to seeing the satin chrome plugs and oil rubbed bronze deabolts. But before they hit the plating room, just about every piece is dull brass, literally. The plating room has massive, and I mean massive, tanks to apply the finishes to the various components. I’m sure it’s very much a science to ensure the same bright brass finish produced on a Tuesday is the same as the Tuesday a few years prior.
Everything was something to behold and I’m glad I got to see it. I feel like I could spend an entire week inside and still wouldn’t be able to see or fully appreciate a majority of what goes on.
And if any of you are “lock nerds” like I am, I’ll part with a few more pictures you may enjoy. This was my second visit to Medeco – we stopped by on the way back from ALOA this year. Of course, I had to go see the Mechanical Development Company on that first visit.


Thank you very much to Medeco for the invitation and hospitality. Let’s do it again in another 50!
If you would like to know more about the history of Medeco, I wrote an article about the origins of the “Medeco Original” earlier this year. Check it out.

Tyler's Take: Drafting Key Control Policies

Note: This is article is not a primer for key control policies and procedures. 
I don’t proclaim to be an expert on key control policies or procedures but I have created a few from scratch. Maybe that has taught me just enough to be dangerous. Be that as it may, I’m not going to teach you how to draft a key control policy. I’m going to show you how to reference other key control policies to help you craft your own key control policy. If you already have a key control policy you can still utilize this information to evaluate your key control program by comparing it to what your peers are doing.

Key Control Policy Resources

The first resource is ASSA ABLOY’s Key Control Guide: Developing & Managing Key Control Policies and Procedures. According to it’s introduction it “represents hundreds of years of best practices developed and observed by providing the world’s finest key systems.” The Key Control Guide contains a sample key control policy and a sample key request form. It also contains specific application guidelines for areas such as educational K-12, healthcare, colleges and universities, and general office buildings. Whether drafting or updating a key control policy, you can learn a lot from ASSA ABLOY’s Key Control Guide.
The second resource is actually multiple. One of the most important characteristics of an effective key control policy is that it is readily available to those who are required to adhere to it. This is usually accomplished by making key control policies available online, such as on a college/universities’ website. There are dozens of these key control policies available online. Simply search “key control policy” or “key control procedures” followed by either a pdf or .doc file type extension. For example, use the search phrase “key control policy pdf”. Here are a few results of that search string:

Key control policies aren’t the only key control resource available to you. You can also reference other key/credential request forms:

I utilized other key control policies when I wrote my first for an institution; it was invaluable. Whether writing your first, or 3rd, or just seeing how it compares to your peers, publicly available key control policies are great resources.

Patents That Shaped American Locksmithing, Part 4: The Sidebar Lock

The gallery was not found! Patent Number: 167,088 (Google Patents)
Issue Date: August 24, 1875
Inventor(s): Philo S. Felter

Background

Philo S. Felter might be one of the most underrated and unknown innovators in the history of locks. In March of 1868 Philo received a patent for one of the earliest, if not the earliest, wafer tumbler lock designs (Patent No. 99,013). On August 24, 1875 Philo was issued a patent for another revolutionary cylinder design. Philo’s cylinder utilized a locking bar to prevent plug rotation. Philo called it a “fence-bar”, we know it today as a sidebar. When the proper key was inserted it would lift the “notches in the tumbler” to the proper height to accept the fence-bar. Once this happened, the fence-bar could enter the plug far enough to allow the plug to be rotated.
Taking things a step further, Philo implemented multiple “false notches”, or what we now call false gates, in each tumbler. This greatly added to the lock’s pick-resistance. Additionally, if taking the patent at face value, the new cylinder design was to be paired with rim night latches, which were very popular at the time.
Unfortunately, the sidebar design never really caught on at the time. The sidebar concept laid largely dormant in the American market for the next 58 years. Then, as fate would have it, a new mind revisited the concept.The gallery was not found! Patent Number: 1,965,336 (Google Patents)
Issue Date: July 3, 1934
Inventor(s): John W. FitzGerald
Enter John W. FitzGerald. In July of 1934, FitzGerald received a patent for a wafer tumbler lock design that utilized a sidebar. Utilizing 4 different depths (eventually growing to 6) across 6 positions, this new design offered a great number of possible bitting combinations and, unlike the popular pin tumbler automotive locks at the time, it was very, very pick-resistant.
FitzGerald, unlike Philo, had perhaps the greatest series of circumstances that would ensure that his design would flourish:
First, it was the 1930s. Bootlegging, bank robberies, and automobile theft occurred at an alarming rate. Gangsters, mobsters, and crime rings were rampant; criminals like Al Capone, Bonnie and Clyde, and Dutch Schultz were mainstays in the newspapers of the day for their “activities”. As a result, automotive manufacturers and insurance companies were looking to protect automobiles as much as reasonably possible. A lock that offered greater pick-resistant than it’s contemporaries was right up their alley.

Second, FitzGerald was an employee of the Briggs & Stratton Corporation. By the end of the 1920s, Briggs & Stratton had manufactured and shipped more than 11 million automotive locks to nearly 130 manufacturers, including Chrysler, the Dodge Brothers, Ford, and General Motors. At the time, they were largest manufacturer of automobile locks in the world. Needless to say, the design was in the right hands.

Aftermath

In 1935 Briggs & Stratton began selling it’s new sidebar lock to General Motors. It quickly became a hit and would go on to be perhaps the most popular automobile lock ever made, appearing in all GM models for the next 50 years.
Sidebar designs didn’t end with the Briggs & Stratton and GM; other automotive manufacturers, such as Chrysler and Ford, began to utilize sidebar locks as well. Sidebar designs would find additional, widespread usage in high security locks. High security locks utilizing a sidebar include:

  • Abloy Classic
  • Abloy Disklock
  • Abloy Exec
  • Abloy Profile
  • Abloy Protec
  • Abloy Protec2
  • ASSA Twin Combi
  • ASSA Twin V-10
  • BiLock FG
  • BiLock NG
  • BiLock QC
  • Chicago TuBAR
  • EVVA 3KS
  • EVVA DPI
  • EVVA DPS/DPX
  • EVVA MCS
  • Fichet 450/480
  • Medeco3, or M3
  • Medeco Biaxial
  • Medeco BiLevel
  • Medeco Original
  • Mul-T-Lock MT5
  • Schlage Primus
  • Schlage Primus XP
  • Scorpion CX-5
  • Zeiss-Ikon Sperwellen
  • Zeiss-Ikon SK6 ZSE/ZSV

Sidebar designs aren’t restricted to high security locks, however. The following locks utilize sidebars as well:

  • Kwikset SmartKey
  • Schlage Everest 29 SL
  • Schlage SecureKey (Discontinued)

Much like the Blake brothers and the cylindrical lock, Philo S. Felter’s design was well ahead of it’s time. And while Philo might not have received his rightful “due” for this sidebar design, there is a lot to be said about an idea that, nearly 150 years after it became a reality, continues to be a hit.
