Smart Speakers Are All The Rage Today Except....

We have written numerous articles over the last 12 years about locks, lock systems, safes, master key systems, doors, repair techniques etc.

Curiously, smart speakers like those offered by Amazon, Google and others have certainly made many of our lives significantly easier but they are found wanting too, as the above video, comediclee shows,

We posted the above video to our social networking pages and are seeing increasing views and likes from our viewers.

It does bring up a topical discussion though and one we feel is important to our readers here too.

Some of the articles we have written about new age smart locks can be seen here

In the above video, the man returns home only being unable to gain entry. Smart locks, for all their good intentions, suffer from many issues that should be considered prior to purchase.

Issues that can include:

  • Poor Battery Life
  • Weathering
  • Low Security
  • Hardware Failure
  • Increasing Insurance Premiums

Poor Battery Life

Many of today's smart locks operate using 4 AA batteries. We suspect manufacturers decided to use these low power systems due to their extremely cheap price points. 
I find repeatedly, customers often calling for locksmith services where their batteries have failed and they either do not have their mechanical over ride key available or their product has no mechanical key over ride function

It's not just digital smart locks. We are also seeing increasing calls to open safes, where battery failure is a common symptom. Often there are additional issues besides poor battery life including internal wiring not lasting or corroding that contribute to other issues where just replacing dead batteries may seem like a simple fix.


Weathering is another common pitfall that occurs repeatedly with battery operated smart locks. Often, once installed the lock will operate efficiently for sometimes 3 months before the user may need to replace batteries. But even correctly installed locks suffer from earth movements that affect the correct alignment of doors into their frames. This will often make operating the deadbolt too difficult for the motor inside the product to correctly throw the bolt. People may leave their homes expecting their door to lock behind them automatically, whereas they are often unaware that the product failed to adequately lock and secure their doors.

Other weathering issues rarely considered include, many digital smart locks are installed to external doors or prime entry doors, Sure the batteries might be on the inside but the keypad will be outside and naturally affected by changing weather. In some regions high humidity can cause internal  components to attract condensation. The water can make internal electrical components to short circuit. Also, when the weather patterns change to cold conditions, the freezing air and rain etc can cause batteries to wear down faster.

Low Security

Many manufacturers, to compete in the global marketplace, decided to use lightweight materials in the construction of their products. Security and access control are some of the reasons some people choose battery operated lock systems. Why anyone who cares about their families security and peace of mind, would choose to spend ~$195+ for a poor quality digital door lock, that is designed to fail within (often) 2 years, puzzles me!

Remembering that it is often all about price, how much is the security and ease of use worth to you?
Often consumers may spend hundreds of dollars on clothes and shoes or thousands of dollars on furniture, electronics or art only to secure their homes with cheap lock systems, It doesnt make any logical sense.

Hardware Failure

Like mentioned above, "the pain of poor quality lasts longer than the pleasure, cheap price provides"


"if you only want to pay peanuts expect to get monkeys"

Consulting your local trained professional locksmith before purchasing locks or other door hardware would be your best approach, in my opinion. Locksmiths have deliberately chosen to train to provide customers with quality offerings aimed at making your lives easier and secure.

You trust your mechanic to fix your car, You trust your electrician to keep your lights working. You trust your plumber to keep the water flowing. Doesnt it make perfect sense to trust your locksmith to keep your home secure?

Increasing Insurance Premiums

An often overlooked issue that many purchasers of digital door locks rarely consider is how installing a digital door lock might affect the amount of insurance you pay.

A number of companies including Walmart, Amazon and others are embarking on delivering groceries and purchases made online to homes and entering your homes to deliver, stock the fridge etc. These new services are attempts to deal with the porch theft phenomena that has resulted in recent years with the expanding delivery markets, While this practise might be considered more secure and more convenient, are you really willing to open your private abode to persons you dont know?

Insurance companies are salivating at the opportunities presented by allowing access to your private dwellings from people who "don't belong".

Also, many digital door lock users will give each user a code. How sure are you that any person is not sharing a code? How would you know if someone who is not authorized, enters your home?

Mechanical keys provide much more immediate security than digital locks because you must have and use a key to operate your lock. Besides the significantly cheaper cost of mechanical products, no requirement to replace batteries ever, even the ease to lock your door if weather affects your installation, you are better protected by using a key to access your property.

This article is primarily about digital battery operated products. Many commercial systems are significantly more expensive for good reason. They are made with higher quality components, often use stronger batteries or are hard wired to mains power. You see many commercial installations that use card/fob access control systems where you simply present your credential to a user interface. These are deliberately hard wired systems, because they last much longer and work continuously without having to maintain batteries.

Walmart To Offer Free In House Delivery Including Stocking Your Fridge

A new service by Walmart, introduced this week is set to compete with Amazon for home deliveries of products ordered. Except that Walmart will have their couriers unlock your door, enter your kitchen, open your fridge and stock your purchased groceries on your behalf.

All you have to do is install a wifi operated lock to your entry door, give permission to Walmart employees to enter your home and to stock your fridge.

That all sounds wonderful, doesnt it?

Amazon introduced a similar service last year after successfully merging their acquisition of Ring and Bleep into their company, We wrote a few articles about Amazon Key and related services here.

Are you owner or resident,willing to allow people you dont know, permission to enter your home when youre not there, have access to your kitchen and pretty much the run of your house?

Are you prepared to pay the increased insurance premiums that will no doubt be incurred?

Even if these companies compel their employees to wear body cameras, so you can view them as they enter your private home, are you really going to open yourself to the privacy concerns?

Modern technologies are great in idea and sometimes in practise. But some ideas are just plain silly.
As a locksmith security specialist, experienced technician and appraiser, I continue to explain to my customers the pitfalls of some modern electronic battery operated security products. Many will agree with me once they understand the potential security and privacy concerns.

I often discuss with clients about their current push button battery operated deadbolt they may have fitted. In many of these discussions, the client points out that, after the third or fourth time replacing the batteries, they will go back to using the mechanical key. The most common reason, is they did not expect the regular and repeated need to replace batteries, adding significantly to their cost of their chosen product. Combine this with they being locked out of their residence when they least expect it and still requiring to call a locksmith to pick their lock open due to not carrying their key.

Electronics do indeed improve our quality of life. But at the exhorbitant cost of a ~$250+ electronic lock, that is more prone to power failure, weathering, house and door movement etc, requiring increased maintenance over the mechanical products that have been around for hundreds of years, the cost differences alone, one might think to keep using and relying on maintenance free security.

Door Repair - Replacing Broken External Frame Part

 We havent written in our blog for over a month, although we still have been busy with projects.

One project we completed recently, was for a returning client that requested a door repair.

A powerful wind storm had taken hold of his storm door and the door closer failed because the screws that hold the bracket to the frame were not long enough to effectively hold the door to the frame.

The result is what was pictured here, the frame breaking in half, exposing the poor workmanship that contributed to the problem.
 You can see in this second image, where the door frame broke away from the rest of the frame and the exposed hole in the top corner underneath the brickwork.

When we arrived initially to survey the project (free quote), we advised the client that the usual practise was to completely replace the door and frame.

The client inquired as to the cost and we informed them that the average cost in the St Louis region was between $1500 and $2400 depending on the selection of replacement door and frame.

The average cost for a standard external door and frame (no glass window in door) in this region, at discount hardware chains like Menards can be ~$480-$700 depending on color, style and preference. Average installation by a trained and qualified technician can be ~$800 - $1200.
 Notice the shape of the protruding cinder blocks and brickwork.

You can also see how the original door frame is constructed,

The use of round wooden splints to connect the outer part of the original frame to the other section of the frame displays the 'cheapy" construction of an average door and frame.
 This image shows the bottom portion of the brickwork and cinder blocks and the threshold.

The client did contact a few other door installers at our advice to compare costs and called us back because we were the only ones to offer a solution that did not require complete door and frame replacement.

Our cost effective solution was to provide a single piece of hardwood 4x4, custom shaped onsite to the shape of the brickwork and cinder blocks, enabling complete coverage of the exposed cavity.
Because the house was still settling and the foundations shifting (after 50+ years since original construction), the door cavity was crooked and we were required to carefully carve the inside of the hardwood piece to accurately fit around the different protruding bricks and cinder blocks. We used our orbital saw, our power file and hand chisels to expertly carve the inside of the new piece to the required shape of the fitting.

We then attached the outer piece to the inner existing frame with 4" countersunk wood screws and embedded them deeper into the new hardwood single piece, so we could fill the holes after and provide a satisfactory look.

We made sure to have enough length to shape around the threshold too, but the shape of the brickwork still revealed a significantly different size gap at the bottom from the top.

The finished result is not perfect, but significantly improved from before and much longer lasting.

Way more competitively priced than complete door and frame replacement, the total end cost to the client was $870 including all parts and labor.

We caulked around the top and sides of the new trim and frame with water-resistant Silicone caulk (to protect from future wet weathering).

We suggested the client to paint the frame themselves at their convenience (as we are not professional painters). 
An interesting yet time consuming repair, that saved the client a lot of money and looks and operates great,

Remembering back to the beginning of this post, where we mentioned about poor workmanship often being a cause of future issues......

Keyless Security Has Turned The Corner - No External Interface Means Nothing To Attack

VL464 Versatile Deadlock
Pictured here is the fabulous Versatile Deadlock from Outlocks, the distributor of Knock-N-Lock technology, we have previously discussed here over the years.

Knock-N-Lock technology is an upmarket Israeli designed and manufactured, high-security lock system that is virtually impregnable.


Because there is no external keyhole. No keyhole means nothing to attack.

This version of the deadbolt lock is available in hardwired or wireless (battery) operated versions.
It is rather industrial looking but is extremely secure because a would-be attacker will have no knowledge of it's location inside your door.

All Knock-N-Lock products operate with the use of a unique external keyfob

This keyfob is the only way to operate the product.

Following is a video that explains the unique locking system uses and how the technology works.
We have been receiving numerous inquiries from customers lately desiring the highest form of security, due to attackers finding methods to beat virtually all other systems they have installed.

There are a number of products made that we can show you after the break.
All operate with the use of the unique fob.

The product is in use in many Asian countries and is finding traction in North America too.

Tellcard Systems EGT - Awesome Standalone Commercial Digital Access Control Product

 The Tellcard EGT is one sensational product. I have fitted 2 of these commercial digital locks of late and they not only look very professional, they are simple to fit, straightforward to program and easy to operate.

I found these products on recommendation through The Society Of Professional Locksmiths, an organization of like minded professional locksmiths, where I am a founding member.

Tellcard offered a promotion a while back to get their products further into the market. Initially I was shy, but thought "why not".

And I'm very pleased with the end results. But more importantly, so are my customers.
 Inside view is as important as outside view, in my opinion because this is the point of view everyday users will see all the time. The Tellcard EGT houses a battery pack that is easily accessible meaning replacing batteries is a simple task.

Life expectancy of the battery pack with typical use (20,000 operations) in a year is about 12 months.

The extra nice feature of this product is that it is not only operable by battery. It also includes connections within for hard wiring, which means you can also hook it up to your internal alarm system and enjoy mains power without requiring to replace batteries. If power fails, the batteries will be your back up power to maintain access control.
 The particular fitting of this unit was to an existing door where someone had previously installed a handle and separate deadbolt. (You can see where the lazy installer used a knock in bolt instead of a correct wooden door installation bolt) This is the outside view of the application.

We were required to drill 2 additional holes, 1 just below the crossbore hole (deadbolt) and one a little farther below where the original commercial lever or knob would have been.
The inside view shows a clearer image of the original holes where the commercial lock once sat.

The end product and fitting, in the first image above displays a beautiful product that fits with the buildings decor and maintains a uniformity with other products in the building.

We also master keyed the mechanical key cylinder in the lever to allow for the building manager to enjoy unfettered access without having to have multiple differing keys for all doors in the building.

ERA Bolts Makes Securing Unusual Doors A Painless Yet Simple Exercise

 A project we completed this week for a medical surgery was to help them comply with modern HIPPA codes that many AHJ's (Authorities Having Jurisdiction) are requiring medical surgery centers, across the country to comply with.

The call was received to find suitable and cost effective locking solutions to secure cabinets in patient examination rooms that hold drugs and supplies that need to be secured from unauthorized access.

Also requested was a solution to secure a set of double doors on a closet used for the centers computer server. The double door closet was unusual because the doors had been split in two, effectively creating four (4) separated leaves. We suggest this was done to minimize the space being used inside the server room, which also doubled as another patient examination room.

Era Bolt Installed Into Upper Leaf
Installing the ERA bolt, which is a door security bolt that uses a standard STAR type key and mortising it into the bottom of the upper door, allows a simple method for connecting the top leaf to the bottom leaf.

The upper leaf on both sides already have roller bolts that hold the top leaves into the steel door frame.

The ERA bolt is a simple install into the bottom of the upper door on both sides.
Chiseling The Strike Plate Into The Bottom Leaf

The bottom leaf of each door already had flush bolts installed to connect the bottoms to the floor beneath, so all that was required was a simple solution to connect top and bottom leaves.
Many other technicians choose to use surface mounted barrel bolts that sit on the inside surface of each door and while this is a simple and cost effective solution also, it means a user is required to reach around the rear of each door to operate the barrel bolts. The ERA bolt solution allows front operation using a standard key and is painless to perform easily.

In the first image above, you can see we installed a lever storeroom lock to match the upper door. Use of the locks individual key is required to open the lock and the handle cannot be left unlocked.
rather than simply providing the operating key to the authorized computer server technician, we decided to install a Supra mechanical combination key box to the metal frame of the door, to house the operating key. This onsite container means that the server technician is not responsible for possessing the operating key and potentially losing it, requiring the lock to be rekeyed. A user with the combination can access the mechanical key box onsite to operate the door lock. This also offer a significantly inexpensive option to battery operated door locks that require the constant need to replace batteries.

Supra Mechanical Combination Key Box Installed To Door Frame

The actual original request was to install cupboard locks to selected cabinets. We used CompX Double Door Hidden Cupboard locks to provide simple security to double door cabinets and simple cupboard locks on cabinets in each patient examination room.

Cannon Safe Digital Lock Replacement

A few weeks ago we were referred by a continuing client (who has been regularly using our services for about 10 years now), to a parishioner who required some professional services to help with her malfunctioning safe.

The safe in question is made by Cannon Safe Company and is a large 2000lb container most often used as a rifle safe but in this case became the safe for the family business records.

The safe was originally purchased about 20 years ago and worked flawlessly for that time. It used a LaGard brand digital safe combination lock with a purpose made digital dial with the company logo (a canon) on it.

Cannon sold the safe with a lifetime warranty and honored that warranty by sending out a replacement lock and digital dial. The only issue was the customer having tremendous difficulty communicating with Cannon customer service. First, they took 30 minutes to answer the phone, then they kept the customer on hold for 3 hours before dropping the call. The customer called back 3 times with the same result each time, before seeking outside assistance.

Her parish piut her in contact with me and I attended the site, rang and spoke with customer service, organized a replacement lock and the whole call took 45 minutes total.

I then attended a week later to complete the install along with some extra jobs requested.

See the images below

Charlie M. (St Louis, MO) November 2015

Danny was pleasure to meet and was very knowledgable. He explained several lock replacement options but I decided none of them were a good fit for a storm door, however, I did replace a lock on my entry door with a type of lock I had never seen before. I would highly recommend this company.
Patricia J (Bridgeton, MO) March 2014
They were prompt and showed up when he said he would show up. He knew his stuff. I had ordered new handles and he was honest enough to say that we don't need them that he can fix the doors and he did. Made me lock and unlock my doors to his satisfaction so that I knew what to do. Am very, very pleased with the service and cost.
Joyce K (Glencoe, MO) May 2015

The owner spent a longtime with me on the phone helping diagnosis the problem. He was on-time, friendly and helped resolve my issue. I will definitely use him again!

Chris C (Lake St Louis, MO) July 2013

I had a very pleasant experience with Master Key Systems. They came out, did the job (which took longer than expected) and they did not change the price they quoted me. Now, I am not certain that it was a great value for the money because I don't have a comparison, but they did what they said, when they said, for the price they said. Enough said!!!

Antonio B (Saint Louis, Missouri) March 2013

Professional.. Upfront about charges. Fixed the sticky door within 20 minutes. I will recommend Master Key for exterior door issues.

Danny was a master craftsman, knowledgable and professional. I will be calling on him again in the future as well as passing on his services to friends and family.

Marsha L (Saint Louis, MO) July 2012

Danny was excellent! I called him on a Monday to fix a sliding glass door. He happened to have the exact part we needed (and it was not an easy find - we had looked everywhere) and he came over Tuesday evening. He stayed until 8:00 until the job was done, and cleaned up afterwards. He was courteous, professional, and efficient! I could not be happier!

Rachel P Maryland Heights, MO (July 2012)

He did an excellent job. Got there on time and quickly solved the issue. Was very pleasant and explained the situation and how to keep the door from sticking in the future. Would definitely use Master Key LLC again!

Neil F. (Saint Louis, MO) April 2012

Danny was very friendly and knowledgeable, although his apprentice seemed to do most of the work, Danny kept an eye on him to make sure it was done right. He had very reasonable pricing for re-keying.
Greg D (St Louis, MO) October 2011

He was extrememly fabulous and helpful and did a wonderful job. He was very professional.
Shannon M. (Arnold, MO) October 2011

Growing up spending so much of my time in Italy, the uniqueness of the Nova Classico left quite an impression on me. To be able to have and enjoy them in my own home here in the states is a nostalgic indulgence I'm enjoying beyond words. Thank you Danny for coordinating this transaction.

Joseph M (Chicago, IL) September 2011

great job. hired on the spot and he did job right then at great price

Ron B (Arnold, MO) July 2011

I searched the internet and found your services. I received three phone calls within several days. A service call was scheduled. Two gentlemen arrived promptly, analyzed the problem and fixed it.
James & Florenc M Saint Louis, MO July 2011

The repairman was on time and did an excellent job of fixing a very stubborn door lock. He was persistent and cleaned up the work area afterwards. I would use this service again.

Brenda F (Saint Peters, MO) June 2011

Danny at Master Key Systems has succeeded in making the purchasing of our Meroni door locks, from Italy, an absolute breeze. Even though I live in Australia with a 16hr time difference and was ordering door knobs from Italy that weren't in stock, the whole process was faultless. Danny was prompt and efficient with all his emails and made sure we had covered every possible variable so that the product I received was exactly as required. I would have no hesitation in recommending Danny for your next purchase.
Patrick Carr (Canberra, Australia)

Your product really helped because I needed to secure a nurse's station adjacent to a waiting room and needed a pocket door. Unfortunately, no real options were available to lock a pocket door effectively that would keep me compliant with HIPAA and secure an area that stores medical supplies. This was vitally important as this particular waiting room was for "waiting detox patients". Thank you very much.
Randall R The Fritz Clinic (Birmingham, Al) March 2011

Danny was very polite and knew what the problem was and how to fix it. He also gave me some information about other issues that could arise with my door and locks. Will hire again if I ever need that type of work done.
Jason M Imperial, MO March 2011

I had an exterior basement door that dragged when opening and closing. The hinges were not fitting properly and the door frame had shifted, probably due to the age of the house.The screwswould not go far enough into the wall without hitting stone...even using a special drill bit. Dan worked a long time drilling and sanding to shore up the door as best as possible. I know it will never be perfect. He could have easily sold me a new door and the same issue would happen. He was honest, thorough, and did an excellent job without charging me a fortune. I'm satisfied with the door now. If you want an honest, experienced man, Then Dan is the man

Roger M Saint Louis, MO March 2011

I purchased the Cowdroy P697 Pocket door lock with key over the internet. I emailed questions before my purchase and was provided with the answers quickly by return email. The purchase was quick and easy and the lock was shipped immediatly. Installation is quick and easy. But you do need to convert millimeters to inches (use the internet) in the installation instructions. And the lock looks great and works great. I will do business with them again. THANK YOU
