Master Key Systems Explained - How To Design Your Master Key System

Today marks 10 years from when we wrote an article about Master Key Systems and we revise that post today and include it here for your pleasure.....

We wrote (November 25, 2009):

As a blog author and locksmith, as a business owner and statistician, I keenly watch the results using Google Analytics, of the search terms people use while attempting to gather knowledge that may help them to be more aware when purchasing products or services.

I am noticing a significant number of searches recently about master keying although, it may be due to a cardinal lack of understanding about the principle.

It seems that many searches recently are from people who assume that all deadbolts are master keyed. This is simply not true. It is a fallacy.

A deadbolt, or any other lock for that matter, must be purposely master keyed.

There are no pre-fabricated master keys for residential or commercial deadbolt locks.

In bygone years, manufacturers of some bit-key type mortise deadlocks, did produce some of their ranges with a purposely designed flaw allowing for a "skeleton" key to operate. This skeleton key was often referred to as a Master Key.

There are some manufacturers of coin machine locks or cam locks, that routinely produce their locks to be master keyed. The primary benefit in using master keyed coin or cam locks is for commercial situations like an office complex that uses on-site maintenance to minimize the quantity of keys a janitor or other service person can be required to carry. (source...)

Many of the same things we wrote about 10 years ago are still true today.

We here at Master Key Systems America LLC/ St Louis Locksmiths are proud of our continuing longevity in the locksmith trade, currently just a tad over 35 years in the business.

We are lucky enough to have worked on 4 different continents and been exposed to many differing types and styles of key systems, that all have their benefits (and issues) for users in their respective regions.

We are one of the leading Bilock Extreme Security Dealers in the USA, having offered Bilock for the last 14 years, locally,

We have worked with the product regularly since 1983, when we first entered the trade. The product was first made available about 5 years prior.

We explain to customers when designing their master key systems, that our preferred method of creating their system requires establishing a list/spreadheet of doors in their property that they want to operate by key.

We usually survey the premise and will often mark all keyed doors with an individual number often on the hinge or inside of the door frame.
This enables each door to be recorded individually. We will often include details like, hinge location/size/make, door hardware (type of lock), color, kickplate (if required), strike plate type etc.
This allows us to immediately know what the original door products are, if ever asked in future. And allows us to know immediately which keys operate which doors.

On the spreadsheet, we will list each door and it's number across the top of the graph, separated into columns.

We will list the names/employee number of key holders in the left side column.

We will then check the name under the corresponding door each person requires to access.

This simple method allows us to accurately design each system and account for all users.

We prefer to offer all our master key systems using Bilock because it is a restricted keyway that is protected from unauthorized duplication. This means no one can get a key copy without the written permission of the designated authorized signatory. This prevents too may keys being out there and not accounted for. No one can get another key made without the owner/manager's knowledge and permission.

We color code all our Bilock keys for simpler identification. We also emboss the system number, key number and issue number on each key, that means each key is an original and NOT a duplicate.

The method of designing a master key system is important to control access to areas required and dramatically improves the security of a premise.

We still like to recommend mechanical access control key systems because they are virtually maintenance free, require no reliance on batteries or electricity, are significantly cheaper than electronic products and are specifically designed to last 25+ years.

Should you wish to know how master key systems can benefit you and your security, feel free to contact us or your local legitimate locksmith for more personal detail.

Danny was very professional and friendly at the same time. He not only gave me the quote and fixed the exterior door and explained his work. He was prompt and upfront about the work and did the work. He came in time took care of it on the same day. (Sasheethn K St Louis MO) June 2018d out problems but assured not urgent. Please feel free to have Danny pass out my number for my total experience review 314-351-5553

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

Showed up on time for appointment. Was very knowledgeable about the project and offered a solution beyond what I asked to be done.
Stephen G (Chesterfield, MO) May 2015

Daniel was right on time, assessed the problems I had with two doors, made the repairs, and explained what caused the problems to begin with .... He is a "door expert" and a true professional. I highly recommend him.

Vince V (St. Louis MO) May, 2015

Danny was fabulous! He went over my concerns and he provided me with more than a fair quote. He was there when he said he was going to be there. I would highly recommend Danny. Cheers!
Denise S (Imperial, MO) May 8, 2014

Hired Danny to re-key locks on "new" house purchase. He advised to replace with new deadbolts & door knobs on 3 entry doors instead which I agreed with. All doors have 1 matching key & the safety of excellent quality product & workmanship. He also added new strike plate to door frame to complete project.. I recommend as your 1st & only call to a Locksmith.

Denise F (St. Louis, MO) April 3, 2014

Danny was very helpful in solving a pretty complex problem involving many lock.
Scott C (Eureka, MO) March 27, 2014

Needed patio door track to run smoothly. Arrived early, fixed door and explained what he was doing during repair. Quick and easy. Door works great, my wife will now speak to me, and I've become a better dancer.

Mike W. (Arnold/Oakville MO) July 2013

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.
Muthu R (Ballwin, MO) July 2012

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
