How To Re-key Old Yale Mortise Deadbolt Locks

How do you re-key old Yale mortise deadbolt locks? 

This week we completed a re-key project for a new customer that involved these 75 year old Yale double cylinder mortise deadbolts. Pictured here is the image of one cylinder installed to the outside of the back door. At the left of the image you can see where someone had deliberately drilled the connecting screw to remove the ability to unscrew the screw from outside.

To be able to remove the cylinders from these really old Yale mortise deadbolts, both inside and outside connecting screws require to come out before the cylinders can be removed for re-keying.

Getting the screws out is not difficult, but that's why we are called as opposed to a handyman or carpenter contractor.

Just about any locksmith with some experience will know the method and skill required to easily disassemble any lock that uses these type of blind screws or bolts, without destruction and enabling the ability to reuse the same screws or bolts when putting the locks back together.

 Pictured next is the image of the cylinder on my bench, already removed from the door. You can clearly see the connecting screw hole.

This image displays the reverse side of the Yale mortise deadbolt cylinder. This style of Yale Mortise deadbolt lock was designed using the original rim style of pin tumbler cylinder, originally patented in 1865 by Linus Yale Jr.

Rekeying these types of older Yale cylinders can be a trap for younger players or less experienced technicians and we will explain the method below to help you with disassembly.

My pointer here is aimed at the retainer clip that holds the tail piece and cover to the rear of the cylinder and core. It is necessary to carefully squeeze the ends of the clip together first.

The next image shows me applying pressure to the retainer clip to allow the clip to be withdrawn from the back of the core.

Here you can see the clip beginning to come out of the cover plate that holds the tail piece on. Carefully use an awl to lever the clip from the core.

This image shows the retainer clip, almost fully withdrawn from the tail piece cover assembly. If you're careful enough, you will not damage the tiny clip enabling you to reuse it for reassembly,

Next, we were also required to disassemble an equally as old entrance knobset to extract the cylinder core for re-keying. To be able to remove the core (plug) from the cylinder it is necessary to remove the rear tail piece and cap assembly and retainer circlip, before you can then remove the core (plug) from the cylinder and replace the tumblers.

Here is an image of the tail piece assembly and retainer circlip removed and the cylinder ready for re-keying.

Some technicians may choose to not disassemble the clip and tail piece, preferring to remove and replace the top cap from the bible (top pinning chamber).

We choose to not show the actual re-pinning method and combination of the re-keyed locks, to protect the customers interests.

AI Powered 3D Security Camera Manufacturer Closes Down

Back in mid 2017, a new company formed to produce and sell an ambitious new product called the Lighthouse AI Security Camera.

Well known former Google manager Andy Rubin was instrumental in the development of this technology.

Well, another one bites the dust....

The company just announced that they are closing due to insufficient sales orders of the revolutionary product.


Originally the company claimed...

The camera is powered by AI and a 3D sensor that can supposedly distinguish people from pets and recognize faces. Its onboard laser (similar to the 3D sensing devices used by self-driving cars) can measure the structure of what it sees and therefore differentiate objects and people from one another. Because of this capability, Lighthouse promises that you won't be bothered by false security alerts from shadows or pets because the camera can tell small objects from large ones.

The AI also understands normal speech patterns, so you can ask the camera questions like, "Did anyone walk the dog between 10 and 11 am?" The different types of tech within the camera work in tandem to deliver a full experience.

"Custom optics for a time-of-flight camera that directly measures the 3D structure of the environment," CEO Alex Teichman says in a blog post. "Recurrent neural networks for computer vision specifically tailored for use cases within the home. And a natural language interface to simplify -- and amplify -- the user experience."

A announcement on their website (in the source) below explains they are shutting down and closing their doors. It seems apparent that not enough customers were happy to pay $300 for each unit and a $10/month access fee for this advanced technology.

The announcement thanks their few customers for their interest.

Solar Powered Power Option For Controlling Electronic Security Products

In June 2010 we posted an article (below) about solar powered power options designed to be used to enable electronic security products.

We have seen a great number of pageviews for this particular post and thought we'd follow up that article with an opinion about the multitude of electronic wireless, battery powered products that continue to enter this (getting) crowded market segment.

In a number of other articles we have written here, we have continued to question the benefits and quality of many battery powered security products.

We believe that the battery powered security devices, specifically deadbolts, entrance sets and the like can offer only 2 primary benefits that can make them appealing.

These benefits are:
1. The ability to remotely lock or unlock the product and the ability to inquire as to the lock status (is the door locked or not)

2. The ability to set automatic locking on the product, to ensure your product locks independent of human involvement.




Understanding that many consumers today are increasingly interested in the many and varied battery powered options, aimed at simplifying their lives, unfortunately the convincing sales pitches will rarely tell you about the genre's shortcomings. Specifically, the need to be constantly replacing batteries to maintain continued operations and the other primary issue, being that as all doors and frames move with weathering, settling, ground movements etc. your beaut $200+ deadbolt or entrance set WILL become useless before long and suffer electronic operability issues.

We believe that the best security offered by deadbolts and entrance sets, is still the mechanical options that can be physically operated by hand. When a condition occurs that inhibits your ease of use, mechanically you can still play with it to get it to operate. Electronically, this is not possible.

Key Cutting Across The World

Key cutting shops pop up all over the world.

The following images are of key cutting enterprises around the world. We have visited a lot of similar businesses in the different countries we have lived, worked and visited.

Feel free to add your images in the comments section. Post are subject to moderation.

If you recognize any of the locations, please mention where they are. Thanks.

You can see that key cutting goes hand in hand with hardware and locksmithing, but also engraving and other general mercantile many people require.

I have no doubt this shop in somewhere in England.

Talk about a hole in the wall!

Godrej - 19th Century Indian Manufactured Money/Cash Box/Safe - Open And Make Key

 Godrej were a 19th century Indian manufacturer of money boxes, safes and cash boxes who closed down in the early 20th century.

A few months ago, a customer contacted us to get their money box opened and have a key made.

We made sure to take some pics of this very old box and how we made the key.

After combing through multiple key blank provider sources and trying to find even something close, our misfortune to find an appropriate key blank made us decide to modify another key blank that was suited to another product.

This particular box, we sourced back to about 1908. It appears to be in surprisingly great condition for it's age.

You can see the key blank we decided to use to modify.

This money box used a coin slot/note slot on the reverse side
of the key operated lock. The slot has a welded on flap inside that is designed to prevent removing coins or notes from the locked box.

 Some of the tools, we locksmith craftsmen choose to use when impressioning keys to locks include a selection of files.


In this case we used a 4" warding file as our primary file of choice for this project.

The impression system of key fitting is a long time treasured skill, unique to the craft/trade of locksmithery. There are many books written over the years that teach the skill to new players, but practise makes perfect. After all, "Repetition Is The Mother Of Learning", according to popular theory.

One of our most popular posts in this blog is "How To Open And Make Keys To Antique Furniture Locks" and explains the method to impression keys to old fashioned 'skeleton key' type locks without damage.

You can see in this pic, we were required to drastically modify our selected blank and hand file the key. We were required to reduce the guage of the key to enable it to enter the keyway, because we could not find a suitable blank.

The finished key works beautifully in the lock, maintains it's originality (and antique value) and can only be withdrawn from the lock when the door is closed and locked.

Not a difficult project for an experienced locksmith, but rewarding nonetheless.

There are many talented locksmiths around this country and the world who still practise the art of impressioning today.

The skill is unique to the locksmith trade and one that can save customers money and heartache when needing service to their antique lock, safe or furniture product.

History Of Locks - Sargent & Greenleaf

Sargent & Greenleaf are arguably the second most well known lock industry brand. Right behind Yale. Their history dates back to 1857, when young James Sargent, an engineer with Yale & Greenleaf, decided to branch out on his own with his invention, a magnetic dial combination lock.

Halbert Greenleaf was the partner and financier (known today as Venture Capitalist) of Linus Yale Jr. Yes, the same Linus Yale Jr credited with the invention of the modern day pin tumbler lock cylinder system, which was awarded it's patent in 1865. Their joint company was called originally Yale & Greenleaf. Halbert Greenleaf ended his partnership with Linus Yale Jr. at the outset of the American Civil War to become an officer in the Union army. After completing his service, Halbert sought out his former employee James Sargent and decided to finance his company, creating what we know today as Sargent & Greenleaf.

The above 7 minute video gives a brief history of the evolution of the company from it's roots.

It is interesting to see in the video, some of the products that Sargent & Greenleaf produced, many of which are still in operation today in the field. Products like the reversible panic exit device, door security bolts, entrance door hardware, push/pull plates among others.

Below find a 15 minute industrial video from the 1950's that shows the production of Sargent & Greenleaf products.

Hosse & Hosse - A Brief History Of keys

Keys have been in use since nearly 4,000 years ago, according to clay tablets that depict keys used in the Babylonian Empire. The first of these keys looked nothing like the historic keys we might imagine today. Some, in fact, may have been as long as an arm and quite heavy. No way you’d have a keychain filled with these keys.

Similar keys were used in Ancient Greece, most likely to lock temples and other structures of significance. They keys were so large that women carried them over their shoulders. You can view one of these at the Museum of Fine Arts in Boston—the key that once locked and unlocked the Temple for Artemis Hemera in Arcadia.

The Beginning of Modern Keys

Where we begin to see the stirrings of modern keys was Rome. The Romans took the technology developed by the Greeks and refined it for more common use. Of course, only those with belongings to protect were concerned with locking their doors. The keys of this time resemble the skeleton keys we think of when “historic keys” some to mind, but they weren’t quite as advanced.

A Step Up in Technology

During the 6th century, European keys took another leap forward. Lever tumblers within locks were created, so keys could be even more specialized. One look at these keys, and you can see exactly how they may have preceded our modern keys. These keys also featured more decorative accents, which often featured crosses or the shape of a bishop’s miter.

Fast-Forward…Way Forward

Lock technology didn’t advance much for hundreds of years. The advancements that were made mostly occurred in England, most notably the double-tumbler lock invented by Robert Barron in 1778. Then in the 1860s, Linus Yale, Jr. of Massachusetts brought us right into the future with his cylinder lock. From that point on, lock technology grew by leaps and bounds.

While we still use some variation of the models produced by Linus Yale, Jr., we also have some technology the Ancient Greeks and Babylonians might have considered supernatural. Current transponder keys make it possible to enter and exit a vehicle without even touching the key.

And, believe it or not, Hosse & Hosse can help you with historic locks and transponder keys. The lock mechanisms from Ancient Greece are no longer in use, so we can’t help you there. However, if you’d like to repair a lock or produce a duplicate key for your home built in the 1800s, we can. We can also reproduce the transponder keys for your cars and keycards for digital commercial locks if you lose them.

That’s one of the most fascinating things about being Nashville’s locksmith and security hardware provider for 150 years. We’ve seen it all, and we can still do it all, too.

Hosse & Hosse Safe & Lock have been proudly serving Nashville Tennessee for 150+ years, providing the region with locksmith and safe sales and services, architectural hardware, entry systems and good old fashioned customer service.

Unlocking Antique Furniture Locks

Antique furniture locks come in all shapes sizes and styles. Often people lose their keys when the pieces are locked. As a locksmith, I have been called upon numerous times to open and make keys to these antique furniture pieces.

Many antique furniture pieces including curio cabinets, use really old hardware made from brass and iron. Many of the locks are small and can be rusting.

The most efficient and easiest method for opening a locked drawer or door, is to impression a new key to the lock. The impression system of key fitting is the one skill that is unique to locksmithing.
Impressioning is used daily by few locksmith technicians these days and the art and talent is diminishing.

Impressioning enables the use of a keyblank, some hand files and some practised techniques to produce working keys to locks without the need to dismantle the piece of furniture. Largely, there is also rarely any damage to the woodwork, which is a good thing, because this maintains the value of the piece.

How does one impression an antique cupboard lock?

1. Select Key blank
2. Cut down flag to enter keyway.
3. Blacken the flag (with carbon or a match)
4. Insert key into keyway and turn as far as it will go.
5. Turn and wiggle key numerous times.
6. remove key from keyway
7. Examine keyblank for "impressions"
8. File minimally, where the impressions occur on the keyblank

This method need to be continued until such a time that the key operates the lock smoothly. It is a talent that few tradesmen technicians still use today. It definitely requires practise, but it save the needs to dismantle a perfectly good lock.
