Medeco locks are engineered for superior pick resistance, drill protection, and key control — making them a trusted choice for homeowners, property managers, and businesses that need lasting physical security.
About Medeco Locks
Medeco is a Virginia-based manufacturer with more than five decades of engineering behind each lock cylinder they produce. Unlike standard residential locks — which can be bypassed with basic picking tools and copied at any hardware store — Medeco cylinders combine three distinct security features in a single mechanism.
The patented rotating pin tumbler system requires both vertical and rotational movement from each key cut before the cylinder will rotate. This dual-action requirement makes the lock significantly more resistant to picking, bumping, and shimming than standard pin tumbler designs.
The keyways and key blanks are also patented, which means Medeco keys cannot be duplicated without authorization from the lock owner. Unauthorized copies simply cannot be cut at a standard key-cutting counter.
About Medeco Locks
The rotating pin system requires each pin to move in two planes simultaneously. Standard picking and bump-key techniques that work on conventional cylinders are ineffective against this dual-action mechanism.
Medeco key blanks are patented and restricted. Keys cannot be duplicated at general hardware stores or copy centers. Only authorized locksmiths with proper dealer credentials can cut replacements.
The cylinder housing includes hardened steel inserts positioned at key attack points. Attempts to drill through the plug are met with material that deflects standard drill bits and resists forced entry.
Medeco deadbolts and knob cylinders install on standard residential door preparations. Most existing door hardware can be upgraded without modifying the door frame or drilling additional holes.
Commercial-grade Medeco cylinders are available in mortise, rim, and padlock configurations. They are well-suited for office buildings, retail spaces, and multi-tenant properties that require high-security key control.
Correct Medeco installation requires proper alignment of the cylinder and strike plate to maintain security tolerances. Arch City Locksmith technicians are trained on Medeco hardware and carry the appropriate tools.
For Homeowners
Homeowners in St. Louis choose Medeco deadbolts and entry sets when they want a lock that performs beyond what standard residential hardware can offer. The patented key control system is particularly valuable after a move, a lease change, or any situation where previous key holders are unknown.
Medeco deadbolts install into standard ANSI door preparations, so in most cases the existing door does not need to be modified. Arch City Locksmith can assess your current door hardware and recommend whether a cylinder replacement or a full deadbolt swap is the right approach for your property.
For Businesses
Businesses in St. Louis that manage multiple keyholders — employees, contractors, property managers — benefit from the key control that Medeco cylinders provide. When a key is lost or an employee leaves, a standard lock can be inexpensively rekeyed. With Medeco, you also have the assurance that copies cannot be made without your authorization.
Medeco commercial cylinders are available in configurations that fit mortise locks, rim cylinders, padlocks, and exit devices. This flexibility means existing commercial hardware can often be upgraded without full replacement, reducing costs while significantly improving the security level.
Why Arch City Locksmith
Arch City Locksmith stocks Medeco hardware, carries the correct tooling for cylinder installation, and services both residential and commercial properties throughout St. Louis and St. Charles counties.
Medeco is one of a small number of lock manufacturers whose products meet ANSI/BHMA Grade 1 standards and carry UL 437 certification. That certification requires the lock to survive extensive physical attack testing, including picking, drilling, and key-duplication attempts under laboratory conditions. For St. Louis property owners evaluating high-security hardware, UL 437-rated cylinders represent the upper tier of commercially available lock security.
Standard Grade 1 deadbolts meet basic residential security requirements, but they do not include key control or advanced pick resistance. A locksmith or experienced burglar with common picking tools can open most standard pin tumbler cylinders in under a minute. Medeco cylinders are engineered specifically to defeat those same techniques, which is why they carry a separate UL 437 rating rather than relying solely on ANSI grading.
Key control is the other meaningful distinction. Standard keys can be copied at hardware stores, pharmacies, and big-box retailers without any authorization from the lock owner. Medeco key blanks are patented, tracked through a dealer network, and cannot be legally duplicated without the owner presenting an authorization card issued at the time of installation.
Medeco cylinders are available as standalone cylinder inserts that fit existing deadbolt housings or as complete deadbolt assemblies. Installing a cylinder insert requires removing the existing plug, which varies in complexity based on the current hardware brand and configuration. Full deadbolt replacement is straightforward on any standard door preparation and typically the cleaner option for doors with older or worn hardware.
Proper installation includes verifying that the strike plate is adequately anchored and that door alignment does not put lateral pressure on the bolt. A Medeco cylinder installed in a misaligned door will experience premature wear, and the security tolerances the manufacturer engineers into the product depend on correct fitment.
Arch City Locksmith provides Medeco installation and service across St. Louis City, St. Louis County, and St. Charles County. We carry common Medeco configurations in stock and can order specialty hardware when the job requires it. Our residential locksmith and commercial locksmith teams both work with Medeco products, so whether the property is a private home or a multi-tenant office building, the same level of service applies.

FAQ
Medeco is a manufacturer of high-security lock cylinders based in Salem, Virginia. Their products are UL 437 certified, meaning they have passed independent laboratory testing for pick resistance, drill resistance, and key control. Medeco uses a patented rotating pin tumbler system that requires each key cut to engage pins in two planes before the cylinder will rotate.
Medeco cylinders are significantly more resistant to picking than standard pin tumbler locks. The dual-action pin mechanism defeats standard picking and bump-key techniques. While no lock is unconditionally pick-proof, Medeco cylinders require a level of expertise and time that places them well outside the capability of opportunistic forced entry.
No. Medeco key blanks are patented and restricted to an authorized dealer network. Standard key-cutting machines cannot cut Medeco blanks, and the blanks are not available through retail channels. Copies can only be made by an authorized Medeco locksmith when the owner presents their authorization card.
Yes. Medeco deadbolts are manufactured to fit standard ANSI door preparations. Most residential and commercial doors do not require modification. If you are replacing only the cylinder inside an existing deadbolt housing, compatibility depends on the current hardware brand, which a locksmith can assess during a visit.
Medeco hardware is priced above standard residential locks. The exact cost depends on the product configuration — deadbolt, mortise cylinder, padlock, or rim — and the quantity needed. Contact Arch City Locksmith at (314) 916-3177 for a quote specific to your property and door preparation.
