What We Offer
Patented Elevation & Rotation
Medeco cylinders require pins to be both raised to a specific height and rotated to a precise angle, defeating conventional picking techniques.
Anti-Drill Hardened Steel
Strategically placed hardened steel inserts within the cylinder face and pins aggressively destroy drill bits and resist extreme physical force.
Protection Against Bumping
Because the pins must be rotated, a requirement standard bump keys cannot fulfill, Medeco locks are inherently bump-proof.
Restricted Key Duplication
Key blanks are protected by utility patents. Duplicates can only be created by an authorized dealer upon presentation of an authorization card.
Medeco High Security in Washington DC
Government contractors, secure facilities, and residential property owners across Washington DC use Medeco when they need locks that standard hardware cannot match. Medeco is manufactured in the USA and represents a genuine advance in physical security over standard residential deadbolts.
DC Local Locksmith installs, repairs, and master-keys Medeco hardware across the DC Metro area.
Mechanical Superiority: Elevation and Rotation
The security in Medeco comes from its patented biaxial pin tumbler design, used in the Medeco M3 and Medeco 4 (M4) systems.
- The Problem with Standard Locks: Normal locks only require a key to lift a spring-loaded pin to a specific height (elevation). Tools like bump keys exploit this simple vertical movement to open the lock violently in seconds.
- The Medeco Solution: Medeco pins feature specialized, angled bottom cuts. The key is milled with corresponding angled cuts. When the key is inserted, it doesn’t just lift the pins; it physically rotates them to a highly specific angle.
- The Sidebar: Only when all pins are perfectly elevated and perfectly rotated will a secondary locking sidebar drop into place. This complex, multi-directional requirement makes Medeco locks effectively immune to lock bumping and exceptionally difficult for even expert locksporters to pick.
Brute Force Protection
Urban security has to resist both lock picking and physical destruction. Medeco cylinders are built for both.
The brass cylinder housings are reinforced with multiple hardened steel inserts precisely positioned in front of critical attack points. If an intruder attempts to drill the shear line or the mounting screws, the drill bit hits this hardened steel and shatters or spins off-center. When paired with a heavy-duty Medeco deadbolt chassis, the system can withstand intense hammering, wrenching, and kick-in attempts.
Total Key Control
For landlords, property managers, and business owners, the greatest security threat is often authorized users making unauthorized key copies. Medeco solves this via structural patent law.
- Medeco key blanks are protected by strict patents and are not available on the open market. You cannot take a Medeco key to a hardware store kiosk or a big-box retailer and have it copied.
- DC Local Locksmith requires formal identification and the proprietary authorization card originally issued with the lock system before we will cut a duplicate key.
- When you fire an employee or an Airbnb guest leaves, if they hand you back the Medeco key, you know with absolute certainty that no unauthorized copies exist in the wild.

Medeco High Security in Washington DC FAQs
Why should I upgrade my home to Medeco?
Most standard hardware store deadbolts share massive security vulnerabilities: they can be 'bumped' open in seconds, the keys can be duplicated easily at hardware store kiosks, and the metal can be easily drilled. Medeco eliminates all three issues. It guarantees no one can copy your key without your permission, and it stands up to severe brute-force and covert attacks.
Can DC Local Locksmith copy my existing Medeco keys?
As an authorized dealer, we can duplicate Medeco keys (such as Medeco M3, Medeco X4, and Medeco 4), provided you have the corresponding security authorization card that matches the lock hierarchy. We maintain strict control protocols to ensure unauthorized individuals, like former tenants or disgruntled employees, cannot obtain copies.
Do I need to replace my whole door handle to install Medeco?
Not necessarily. Medeco manufactures highly versatile cylinders designed to retrofit right into existing hardware. We can often remove the generic cylinder from your current Schlage, Yale, or Kwikset lever or deadbolt, and replace the core with a high-security Medeco cylinder, significantly upgrading security without altering the decorative aesthetic.
Are you licensed and insured for residential work in DC?
Yes. DC Local Locksmith holds a current DC and MD license, is fully bonded, and carries general liability insurance. Documentation is available on request.
Do you offer after-hours service for home lockouts?
Yes. Our dispatch line is staffed 24 hours a day, 7 days a week, including holidays. Quoted before dispatch.
Which lock brands do you install and service?
We install and service Schlage, Yale, Kwikset, Medeco, Mul-T-Lock, and most ANSI-rated residential hardware. We can supply hardware or install what you provide.
Should I rekey or replace my locks after moving into a new home?
Rekeying is the faster option when the hardware is in good condition and serves most change-of-occupancy needs. Replacement is warranted when hardware is worn, damaged, or below ANSI Grade 1 standard. We confirm which path fits your hardware during the quote.
Can you cut additional keys on-site?
Yes. We carry key blanks for most residential cylinders and can cut copies at the time of service.
What is ANSI Grade 1, and do I need it for my exterior doors?
ANSI Grade 1 is the highest residential security rating, tested for 250,000 cycles, 6 attempts at 75-pound force, and pick/drill resistance. We recommend Grade 1 on all exterior doors and Grade 2 minimum on interior doors.
What is your protocol for eviction-related lock changes?
We require a copy of the court order before performing an eviction lock change. We do not perform lock changes on occupied residential units without legal authorization.
