Retrofit into existing lock housings

An electric cylinder looks like a normal key cylinder, but it has a chip inside. It fits into the lock you already have, so there is no door cutting and often no wiring. Each key is programmed with who can open which door and when. If a key is lost, you delete it in the software instead of rekeying. The cylinder also keeps a log of every entry. That makes electric cylinders a smart choice for offices, clinics, hotels, and public buildings across the DMV.
Most models draw power from a battery in the key, so doors need no new cables.
See who opened each door and when, which helps with HIPAA, security reviews, and incident checks.
Lost or stolen keys are blocked in minutes from your software, with no costly rekey needed.
King Locksmith And Doors Inc. is a commercial locksmith and door company serving Maryland, Washington DC, and Northern Virginia. Our technicians install, program, and repair electric cylinders for small businesses, government agencies, hospitals, hotels, and enterprises. We match each cylinder to your existing locks and how each door is used. From one office suite to a full campus, we plan the key system, set up the software, and train your staff so everything runs smoothly.
Not every electric cylinder suits every door. Use these five checks to match the right cylinder to your locks, your security needs, your budget, and the way your team works each day across every site.
Electric cylinders come in mortise, rim, key-in-knob, key-in-lever, and euro profiles. The right one depends on the lock body already installed on your door. Getting the size and cam right means a clean swap with no drilling or door damage.
We check the cylinder length, cam type, and door thickness before we order. This avoids returns and project delays. It also lets us keep your current handles, trim, and finish in place on every door.
Some electric cylinders draw power from a battery in the key. Others keep a battery inside the cylinder itself. Key-powered models need no upkeep at the door, which helps on remote gates, cabinets, and utility rooms. This design also means fewer parts to fail.
Cylinder-powered models can work with simple fobs or phones, but each battery needs changing on a schedule. We help you weigh battery care against the convenience your staff wants every day.
Offline systems store access rights in the key. Staff update their keys at a wall programmer or through a phone app. This works well for large sites with many doors and no network at each door.
Online systems push changes to doors right away, but they cost more to set up. Many DMV clients mix both, using online control at main entries and offline cylinders on interior doors. We help you choose the right balance.
Look for cylinders tested to ANSI/BHMA A156.30 or UL 437 for high-security use. These tests cover lock picking, drilling, and forced attack. Ratings matter most on server rooms, pharmacies, and evidence storage.
Government and healthcare sites may also need specific approvals or audit rules. We confirm what your policy or insurer requires before we recommend a product, so you meet the standard the first time. We also flag doors where a lower grade saves money.
The software is where you add users, set schedules, and pull reports. Some platforms run in the cloud, while others install on a local server. Pick one your IT team can support and secure.
Think about growth too. A system that handles 20 doors today should handle 200 later without a full swap. Ask how license costs change with size. We design key plans that scale with new floors, buildings, or tenants as you grow.
Both types fit the same lock bodies, but they work differently. Here is how electric cylinders compare with mechanical key cylinders on the points that matter most to facility managers.
