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.

Facial Recognition Technology Has Really Come Of Age Thanks To Apple Iphone - Check Out This facial Recognition Security Device From About 10 Years Ago

Almost 10 years ago we wrote an article about some facial recognition technology and especially one particular product that we also sold a number of.

The post we wrote in December 2009 was one of the last posts that year, but proved to be wildly popular. I dont know why exactly.

I have sold about 4 of these units and I believe my customers are still using them today.

Face Recognition Security - For Doors

I have been touting the use of biometric access control systems, especially residential fingerprint controlled door locks, for quite some time.

Recent experience installing some of these products has lead me to understand some of the pitfalls of the technology, especially age related syndromes that affect interface operation by elder users.

Here is a new product, recently released that adopts a variation in biometric access technology.

Facial recognition technology is still in it's infancy compared to other existing biometric systems (like fingerprints etc). Embrace the world of advanced time attendance systems. Beautifully designed to compliment any imaginable décor, this facial identification time attendance system recognizes faces in 3D by utilizing the internal dual sensor and dual camera that allows it to establish an incredible facial recognition algorithm in a fraction of a second.

At a Glance...

• Lock and unlocks doors
• Face recognition technology
• Record employee attendance
• Time keeping and data logging
• Export and Import from a TXT file
• Download recorded data via USB or TCP/IP
• Included software for detailed record keeping and analysis

Scammers Still Infuriating The Wider Market and Industry - Post Revisited

A little over 5 years ago we posted the article below and have seen significant numbers of pageviews therein.

The issue of scammer locksmiths continues to plague the wider consumer market, but it's not just locksmiths. It is also a number of other once highly respected industries too.

In the article below, there is a video by #ABCTHELOOKOUT which was a current affair series exposing nefarious alleged scammers in a host of differing services.

We still advise all our customers and all consumers to be cautious when choosing your desired professional.


From June 2013....


We have warned consumers many times over the past 5 years about the slew of scammer companies posing as locksmiths ripping off victims, all across the United States and Canada.

These perpetrators are now invading many other countries operating similar scam operations in Australia, New Zealand, Great Brittain and other European countries.

This news is not really news to the locksmith industry but thanks to the Network Television companies, like #ABC, prime time television now has provided a much wider net to expose the shenanigans.

My good friend and colleague, Mike Bronzell of All Hours Locksmiths in Chicago, has been one of the leading voices exposing these crooks for the last 10 years. I joined Mike about 5 years ago in Chicago to watch a case filed against Dependable Locksmiths by the Illinois Dept Of Professional Regulation. that prosecuted one David Peer for running a similar scam company. (the court found the company guilty of fraud and fined them and cancelled their business licenses, but they simply popped up again under a different name to continue their victimizations. Just this year, in February we discovered that all charges against this company had been dropped and the judgement overturned due to improper court procedures)

The leader of the company operating these scams has finally been exposed, thanks to the in depth investigation and reporting by the team at #ABC's The Lookout, a highly acclaimed television series developed to provide the marketplace with expose's on many ripoff artists scamming consumers across the USA.

Meni Agababayev is the name of the owner of this company. 




The video above is the whole episode from this weeks #ABC's The Lookout, but the actual story we are referring to runs for the first 20 minutes.

Door Frame Repair - After Break In, Using Strikemaster II

We just completed another repair project on behalf of a property management company, where the tenant had been the victim of a burglary attempt where the door was kicked in and the frame failed.

We are not painters and advise our clients of such during the estimate phase. We are happy to perform the required repairs quickly and at the residents convenience.

Below you can see the "before" images and understand what we were about to encounter.

 This view is from the Garage side of the door we were to repair.

We advised the property manager that future painters would also be required to repair the walls and gaps around the exterior side of the frame.

Whomever had rehabbed this place, obviously decided to cut corners to save money (a common action of house flippers)

 You can see the damage to the interior trim, the location where the strike for the entrance set and deadbolt has completely been broken out. Also the paint on the inside wall was torn away in the attack.

Here is a better angle of the damaged door frame.


This project type is one of our common project requests. Customers requiring to fix a broken door frame after suffering from door frame failure resulting from a kick-in attack.

When considering to repair or replace the entire door and frame, understanding that the average cost in the local market to supply and install a new door and frame can be ~$1100 - $1500 for a quality professional to install a standard door and frame, it becomes worthwhile to seek alternative solutions that reduce cost while upgrading the security of the location.

Enter the Strikemaster II. This phenomenal security and repair product is expertly designed and manufactured in the USA. A Safe Homes is a company based in the Carolinas that is on the forefront of product development, especially when it comes to safety, security and protection of the doors we all use daily.

This next image shows our completed repair using new trim and the Strikemaster II expertly installed,

Comparing this to the before pictures shows the entire gaping hole left by the door kick-in (where the entrance set latch and deadbolt go), is now completely hidden.

You can still see the area that requires painting, another project for another tradesperson for another time.

 This image shows a different angle of the new trim and the still damaged paintwork.

Professional painter and decorators will first use caulk to seal the gaps between connecting pieces, Some painters will also remove the trim and paint the wall, then re-install the trim, creating more professional looking lines, that can then be caulked after the paint dries

This final image of the completed project shows a better view of the Strikemaster II. the unique patented product uses a 2 part process to create a "laminating" effect. Also the outer steel uses a lip designed to hook around the edge of the door frame. This lip is an integral part of the product design, because it increases the strength of the product when being attacked.

Strikemaster II also uses stainless steel screws about 3" long, that tie the product, through the flimsy thin frame, to the stud behind, effectively anchoring the new product and providing almost impenetrable strength.

Being 5' long and using 8-10 stainless steel screws, combined with the lip and the laminating effect, the product is very strong because a new attempt to kick-in the door will spread the weight applied by the kicking action across a wider surface.


It is unfortunately, all too common that a great many homeowners, property managers, residents and tenants just are not proactive enough to anticipate future events like door frame failure, by installing products like this in advance of an event. Perhaps purchasing new designer shoes is of greater importance than providing security protection for your family and colleagues.

Speaking to your local locksmith can provide you with some great knowledge and experience to effectively mitigate issues and events down the road.

This entire repair project cost about $300.00 and they could maintain their existing door and frame. Compare that to the average door and frame replacement cost, that does not apply similar door frame strengthening to prevent another kick-in attempt and you effectively spent almost a thousand dollars more without increasing security and protecting your family and possessions satisfactorily.

Repairing Building Entry Door Using Plast-Aid

Often we find ourselves receiving calls from customers who request repairs to their entry doors on commercial premises.

There are many and varying types, styles and functions of entry doors, used across the world. In the United States, many commercial entrances use aluminum shopfront entrances, often installed by professional shopfitters.

Last week a client called us to repair a shopfront aluminum entrance door on their church entry.
This door was probably about 40 years old, judging from the style, the lock, the fading etc.

The initial repair was simply a readjustment of the door closer to enable correct closing distance.
We explained to the client that the use of double cylinder locks on primary entrances is a violation of building codes/life safety codes. We recommended they contact their local AHJ (Authority Having Jurisdiction) to get in writing, permission to use an inside cylinder on their entry door, while explaining that potentially, their insurance could be void if someone was locked inside and unable to easily escape. Life safety codes trump security, especially on commercial dwellings.

Here is an image of the outside of the front entry door. You can see where someone previous to me, decided to attempt to upgrade the security of the door, by installing a long metal plate along the door edge, to attempt to prevent a would be intruder from gaining access without damage.

While this is a great suggestion to increase the security of an entrance, in this particular case, the installer actually reduced the security of this entrance by removing the strike plate from the door jamb making the gap between the edge of the door and the door jamb too wide - preventing the deadlatching activator from operating correctly and making the latch mechanism easily able to be loided (latch pushed in using a screwdriver or plastic card)

This image shows the strike removed from the door jamb.

We thought of multiple ways to effect a simple repair to this issue, to reduce the gap between door and jamb, when closed.

We settled on a repair using the fabulous Plast-Aid moulding repair product.

We combined the Plast-Aid powder and ointment to a sufficient amount for the project, letting it cure to the point of a useable putty.

We applied the putty to the door jamb, where the strike plate would normally fit and let it harden sufficiently to recreate the function that the strike plate would provide.

The Plast-Aid product hardened in about 10 minutes and made the region of the door that the deadlatching pin was to hit, wider ensuring that the pin would then activate the security of the latch mechanism.

You can see in the next image, the door almost closed and the Plast-Aid repair product, jutting out sufficiently to encounter the deadlatching activator,

The local AHJ had already been and required them to change the double cylinder into an inside turnbutton, while allowing them to continue using the paddle on the inside and not having to replace the whole fitting with a panic exit device.

this image shows the latch mechanism fully seated in the strike hole (where the strike would normally have been fitted), contacting the deadlatching activator and securing the latch mechanism from loiding.

This whole project enabled us to maintain using the custom made blocker plate installed by the previous technician but repair the deadlatching feature and provide  stronger security, as intended by a dealatching lock system.

Pocket Door Repairs

Being a professional contractor who specializes in locksmith services and door repair services and products, allows me to offer unique and specialized products and services to a varied range of clients.

We have been continued members of the Home Advisor network, coming on 12 years, ever since it's early inception as Service Magic. The parent company of Home Advisor, ANGI Repair Services, recently completed their acquisition of Angie's List and have melded the Angie's List network into the Home Advisor network to create the largest lead generation service online.

We receive a great many leads from the network and over the years have been lucky to receive 370+ reviews from satisfied clients.   (View Our Home Advisor Page Here And Read Our Reviews)

One of the not so common requests we receive is "Repair Pocket Doors".

It has become an interesting and increasing number of inquiries from customers who suffer from pocket doors that drop wheels or tracks not holding sufficiently longer and doors not straight.

There are obviously far too few tradespeople in my region, capable enough to repair pocket doors.

Below, find some images we took on a recent pocket door repair. The customer could not find anyone to perform the repair (before me) with almost all contractors they contacted, refusing to repair stuff preferring to only tear out and replace. Doing such, would add significant cost to projects and take much longer than just a repair.

dont forget to remove all the little nails

In the images above, we display the methods we use to create as little mess as possible and performing the dismantle without the need to cut into the wall, we always survey and estimate all repair jobs in advance and inform the customers that we are not painters and do not paint and caulk.
We always tell the customer that they may need to caulk and paint afterward.

Being careful to cut the edges of the trim and frame will allow you to pull the trim without affecting too much of the existing paintwork,

Remove the trim from top and sides of one side of the door only. Dont forget to remove all the little nails you find, to avoid having difficulty taking the door out and difficulty reattaching the trim after completing your repair.


We deliberately do not show the inside workings in this example repair because we dont want to give the whole farm away.

The next images are the after images with the repair completed and the trim reattached. You can see, that using this method can save you a lot of money and heartache. We reattached the trim using our nail-gun and the end result is a repaired and suitably operating pocket door.

 Here you can see the reattached trim and the slight damage to the paintwork, that the customer will fix themselves.

 This is the completed door from inside the bathroom

 Another look from inside, post repair

And this is the look after cleanup from the vanity side of the bathroom.


The entire project took about 3 hours to complete and did not involve any new parts, apart from some nail-gun nails.

Sliding Doors Are One Of the Weakest Links In Your Home - What Can You Do?

We originally posted the following article in June 2010. Consulting your local trained professional locksmith can help you to understand the many and varied products we can supply and services we can perform to improve the security of these sliding patio doors




The above video is actually an explanation of how to replace a sliding door installation with french style doors but it does highlight the ease in pulling the common sliding door from it's tracks.

I am called upon often to repair sliding doors, that have become increasingly harder to operate. There are multiple reasons that doors can become inoperative, but we will leave that for a later article.

The reason I decided to include the above video here is to highlight the extreme weakness that almost all sliding patio doors suffer from.

You can see how easy it is to lift the door from it's track. When the door is closed, it is usually held locked by just a metal hook. Often that hook is all that is preventing the door from being opened. I have seen many instances where the sliding door is the principle method of surreptitious entry. Often intruders simply use a large screwdriver or prybar/crowbar (found in most automobiles) and lever under the bottom of the door, raising the whole door frame enough to remove the door completely from the track. Even while still locked.

There is a very simple and cost effective measure that can be applied to prevent most sliding doors from being removed in this fashion.

Simply, install a self-tapping screw into the top track, so that the head is protruding enough to allow the door to still slide but reduce the lift, or amount the door can be raised.

Some lock manufacturers include anti-lift pins in their locks to help with this problem, but often the parts are made from die-cast aluminum, which is weak and brittle.

For about 50 cents you can prevent the door from being lifted off it's track.

Many people insert a piece of dowel or length of wood into the track behind the door. While this is probably one of the cheapest and best methods for preventing the door from sliding open, it does nothing to stop the door from lifting up.

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.
