Juggling thirty keys, or handing out copies you can’t track? King Locksmiths designs grand master, keyed-alike, and restricted keyway systems, installed by insured technicians with genuine hardware from leading brands, upfront pricing, and 25 years serving the DMV. Call now or schedule online.
A master key system gives each person exactly the access their role requires: one key for the owner, a sub-master for managers, a change key for every tenant or office. A restricted keyway stops unauthorized duplication, and a proper keying schedule lets us rekey one door without disturbing the rest.
Handyman setups with cross-keyed cylinders create ghost keys that open doors they never should. Licensed, Bonded & Insured, King Locksmiths has engineered key hierarchies across Maryland, Washington DC and Northern Virginia for 25 years. Request a free master key quote today.
Property managers running dozens of units and government facility directors with strict key control requirements keep calling King Locksmiths because our systems work exactly as drawn, every key accounted for, from Maryland through DC into Northern Virginia.
King Locksmith was the absolute best! They communicated incredibly well, were prompt, reasonably priced,, super efficient and really, really nice. Definitely 5 stars! Don’t look any further. A must use company!!!
We had a great experience with King Locksmith and Doors. They were professional, prompt, and knowledgeable from start to finish. They took the time to explain everything, completed the job efficiently, and made sure everything was working perfectly before they left. It’s clear they care about their customers and take pride in their work. I highly recommend them to anyone looking for reliable, honest, and high-quality locksmith service. Thank you again!
Big shout out to technician Vernon. I ran into an unexpected problem in changing the code on an older lock that I have successfully done a couple dozen times in the past 20 years. I called King Locksmith and they sent me Vernon. Although not familiar with my old lock, he had the expertise to find the info he needed to resolve my issue. Not only was he very competent, he has very good customer service manners and accepted my attempts to be helpful.
A neighbor recommended this company for trickier doors in an older house. Mightily impressed by Vernon, master locksmith, a new hire at King Locksmith and Doors, who was knowledgeable and personable. He was able to reinstall a lever and lock that had been removed by a handyman (who then could not figure out how to put it back in), and bring it back to full function, thereby securing a whole area of the house. Vernon also assessed other doors and locks that have been giving us trouble, outlining the process for repairing and replacing each. We will be using King Locksmith and Doors again, and requesting Vernon when we do!
Their professionalism and customer service is superb. This team will follow up regarding status of technician name and arrival times, delivery of parts ordered, etc. From the moment you call you are treated with respect and courtesy. They did an outstanding job.
King Locksmith and Doors did an amazing job installing my new screen door! The whole team was professional, on time, and very easy to work with. They helped me choose the right screen door for my home, and the installation came out perfect. Everything looks clean, fits great, and works smoothly. You can tell they really care about the quality of their work. I’m very happy with the results and would definitely use King Locksmith and Doors again for future projects!
King Locksmith never disappoints!!! I hired them for the second time after an amazing experience a few years ago. Hard to believe that they could improve, but their service — and their team — has only gotten better! From first contact on the phone (and I apologize for not remembering the name of the lovely, helpful woman I spoke with who arranged the serrvice call super promptly) to the actual service less than 24 hours later, King Locksmith is stellar!!! Vernon, the locksmith who performed the work at my house, was phenomenal. Not only did he address the problem with my lock, he went above and beyond devising an elegant solution to what could could have been a slap-dab job had it not been performed by a professional like Vernon. He is a true asset to the King Locksmith team! You’re lucky to have him! Highly recommend King Locksmith!
We couldn’t turn our knob inside or outside to enter or exit. King Locksmith saved the day on a Saturday no less🤗 This is the third time I’ve used them. They are definitely my go to for locksmiths in a lockout or if you just need to change the locks.
I had such a wonderful experience with King Locksmith and Doors Inc. This is the first time I’ve used their services, and they truly exceeded my expectations. My most recent project was a major storefront door repair after a burglary. The glass was broken, the lock was badly damaged, and the door was almost falling off the hinges. From the moment I contacted King Locksmith and Doors, they professionally walked me through the entire process and provided upfront pricing with no surprises. The very same day, they sent two skilled and professional technicians who completed the work efficiently and within the timeframe they promised. The replacement glass arrived within a week, and they returned exactly as scheduled to install it. They handled everything with great care, responsibility, and professionalism. What really stood out to me was how smooth and stress-free they made the entire process. Their communication, professionalism, and attention to detail gave me confidence from start to finish. I will definitely continue using their services for any door or lock issues in the future. Thank you very much to the entire team at King Locksmith and Doors Inc. for making everything simple and stress-free!
This is the 2nd time in a few years I have used King Locksmith. Always a great job in my experience. This time they repaired a bi-fold door that wouldn’t stay in its track. Technician came the same day and was able to fix it. So nice not to have the door wobbling around anymore.
From a four-door office to a multi-building campus, King Locksmiths engineers every level of master keying for homes, businesses and institutions across the region. Call for a system consultation today.

Master keying is mathematics before it is metal. Get the pinning chart wrong and doors open for the wrong people. Our designers get it right the first time, on every property.
Every system we build starts on paper: a keying schedule mapping who opens what, then a pinning chart that keeps change keys from stumbling onto master combinations. Our technicians have engineered hierarchies for apartment portfolios, medical suites, schools and storefront chains across Maryland, Washington DC and Northern Virginia for 25 years.
That volume means we catch cross-keying risks and expansion dead-ends before installation, so the system works on day one and grows cleanly for a decade.
Master keying is priced by scope, never by surprise. Before we touch a lock, you receive a written quote covering hardware, labor and key blanks, and that number holds unless you add doors.
Your free estimate is shaped by three things: how many cylinders and access levels the schedule requires, whether you choose standard, restricted or interchangeable-core hardware, and the condition of the locks already on your doors.
When a master key goes missing, every door it opened stays exposed until the system is re-pinned. King Locksmiths dispatches technicians already positioned throughout Maryland, Washington DC and Northern Virginia, putting a locksmith at your door in 20 to 50 minutes.
Regional coverage means same-day slots instead of a three-day wait, a tech who knows the route rather than an out-of-area dispatcher, and lost-key lockdowns handled before close of business.
Licensed, Bonded & Insured means the technician re-pinning your building is vetted and any incident is covered, with documentation your insurer will accept.
ALOA and SAVTA membership signals training in current keying standards rather than trial and error. Our local awards come from DMV customers, not paid directories. As a Leading Door Hardware Brands Supplier, we install genuine Medeco, Schlage, Mul-T-Lock and ASSA ABLOY cylinders and key blanks, never gray-market parts.
Fast regional dispatch meets upfront pricing. Reach a King Locksmiths master key technician in 20 to 50 minutes across the DMV. Call today or book your appointment online.
King Locksmith And Doors Inc designs, installs and maintains master key systems for residential, commercial and institutional properties across Maryland, Washington DC and Northern Virginia, alongside lock installation, door repair and access control. Whatever you manage, call and we will map your keying.
Homeowners rarely think about master keying until a rental unit, an in-law suite or a detached garage turns one house into three access zones. We give the owner a single master key while renters and caregivers carry change keys limited to their own doors.
Single-family houses, townhomes, condos and rowhouses across the region get the same treatment: a restricted keyway to end secret copies, quality cylinders, and a keying schedule you actually understand.
Stop wondering who still has a copy. A restricted keyway master key system from King Locksmiths ends the guessing. Call for a free home quote today.
Offices, storefronts, restaurants, medical suites and government facilities need access that follows the org chart. We engineer grand master and great grand master hierarchies with sub-masters for departments, floors or buildings, using commercial-grade cylinders and SFIC or LFIC cores where turnover runs high.
Fire-code egress requirements stay intact, master key compatibility with existing hardware is verified before quoting, and installation is scheduled around your hours so operations barely notice.
Interchangeable core master key systems let you swap cores in seconds. Ask King Locksmiths about SFIC and LFIC solutions for your property. Call or book today.
We walk the property, list every door and user group, then hand you a written quote before anything is ordered.
Our locksmith drafts the hierarchy and pinning chart, reviews it with you, and finalizes it before cutting one key.
Technicians pin every cylinder to the chart, install or rekey hardware, and stamp keys by level, never by door.
Every key is tested on every door it should and shouldn't open, then logged and handed over with your schedule.
Master keying is one piece of what King Locksmiths does. From hardware to doors to electronic access, we secure the whole building. Explore the services below or call for a combined quote.
