Medeco is widely regarded as the premier American high-security lock brand. Their rotating pin mechanism provides pick resistance that standard pin-tumbler locks can't match. Combined with restricted keyway control, Medeco protects both the physical security and the key duplication process.

Medeco products include cylinders (M3, X4, Biaxial), deadbolts (Maxum, 10+1), mortise cylinders for commercial retrofits, and high-security padlocks. Medeco Nexgen adds electronic override for access control integration. All products use the signature rotating pin cylinder and restricted keyway.

Treasure Coast Locksmith is authorized for Medeco service in the tri-county area. This means we can cut replacement keys for Medeco restricted keyways (which can only be cut by authorized dealers), rekey Medeco cylinders, install new Medeco hardware, and integrate Medeco with existing security plans.

Medeco technology, products, and authorized service

Medeco's reputation is built on their rotating pin mechanism - a patented design that requires keys to not only lift pins to correct heights but also rotate them to correct angles. This dual-action defeats picking techniques that work on standard pin-tumbler locks.

Rotating Pin Mechanism: Standard pin-tumbler locks only require pins to be lifted to correct heights by the key cuts. Medeco pins must also rotate to specific angles defined by the angled cuts on the key. Picking tools can't easily manipulate both the lift and rotation simultaneously, providing excellent pick resistance.

M3 Cylinders: Current commercial Medeco standard. Three pin rotation angles plus side bar mechanism. Pick resistance significantly better than Medeco Biaxial (earlier generation).

M3 is the current Medeco commercial product for offices, banks, healthcare, and high-security applications.

X4 Cylinders: Updated Medeco design with additional security features. Used where maximum security is required. More expensive than M3 but provides even higher attack resistance.

Biaxial Cylinders: Earlier Medeco generation. Still common in installed base but superseded by M3 for new installations. We service Biaxial locks where they remain installed but recommend M3 upgrades for new work.

Maxum Deadbolts: Medeco's commercial Grade 1 deadbolt. Integrates Medeco high-security cylinder into robust commercial deadbolt construction. 1-inch throw, hardened bolt, and heavy-duty strike.

Used in commercial applications where both deadbolt security and key control matter.

Commercial Cylinders: Medeco makes rim cylinders, mortise cylinders, and standard cylinders compatible with commercial lock bodies from other manufacturers. Upgrade existing Schlage, Sargent, or Corbin Russwin lock bodies by replacing standard cylinders with Medeco. Common retrofit approach.

Restricted Keyway: Medeco's restricted keyways mean standard hardware stores cannot cut replacement keys. Only factory-authorized dealers can duplicate keys, and duplication requires key number or authorization card. This prevents unauthorized duplication from lost or borrowed keys.

Key Control System: Medeco maintains factory records of all authorized key holders and authorized duplications. Businesses can require authorization for any key cutting, providing audit trail of who received keys when. Essential for key control programs in sensitive applications.

Master Key Systems: Medeco high-security master key systems combine physical pick resistance with restricted duplication. Large institutional master key plans use Medeco for key control where standard master key systems would be vulnerable to unauthorized duplication attacks.

Authorized Dealer Status: Only authorized Medeco dealers can cut restricted keys, order replacement Medeco hardware, and provide Medeco services. Treasure Coast Locksmith maintains Medeco authorization for the tri-county area. Authorization requires ongoing training and compliance with Medeco's key control policies.

See Medeco for product information.

Key Duplication Process: When you need a new Medeco key, authorization must be verified. Typical process: present existing key plus authorization (business card, letter, or signature card), verify identity, cut new key, log the duplication in our records. More formal than standard key duplication but provides key control benefit.

Medeco lock service FAQs

Common questions from Treasure Coast businesses with Medeco high-security locks.

Are you authorized to cut Medeco keys?

Yes. Treasure Coast Locksmith is factory-authorized for Medeco service in the tri-county area. We can cut replacement keys for Medeco M3, X4, and legacy restricted keyways.

Authorization required because Medeco restricted keyways cannot be cut by non-authorized dealers.

How much does Medeco service cost?

M3 cylinder replacement: $195-$395 per cylinder. Maxum deadbolt installed: $495-$895. Restricted key duplication: $35-$75 per key.

Master key system design: quoted per plan complexity. Premium over standard hardware justified by security and key control benefits.

What is Medeco's rotating pin?

Medeco keys have angled cuts that rotate the pins as they lift. Standard pin-tumbler pins only need to lift to correct heights; Medeco pins must lift AND rotate. Picking tools can't easily manipulate both actions, providing excellent pick resistance compared to standard cylinders.

Can I get Medeco keys cut at hardware stores?

No. Medeco restricted keyways can only be cut by authorized dealers. This is intentional - prevents unauthorized duplication and provides key control.

For duplicates, come to us or another authorized Medeco dealer with proper authorization.

What authorization do I need for key duplication?

Usually a signature card or letter from the business or building owner authorizing you to obtain keys. Sometimes business card with matching ID. Policy varies by customer - strictest customers require more verification, more flexible customers require less.

We maintain records for audit trail.

Can Medeco cylinders replace my existing commercial locks?

Yes. Medeco cylinders fit most commercial lock bodies (Schlage, Corbin Russwin, Sargent, Best, Yale) as replacement cylinders. Keep existing lock body and trim, upgrade just the cylinder for pick resistance and key control.

Common retrofit approach.

Should I use M3 or X4?

M3 is current Medeco commercial standard and suits most applications. X4 is for maximum security applications where added cost is justified. Most commercial customers choose M3.

Consult with us during specification for specific application guidance.

Do you service older Biaxial Medeco locks?

Yes. Biaxial is the earlier Medeco generation still widely installed. We service Biaxial locks and can cut Biaxial keys.

For new installations we recommend M3 upgrade but service existing Biaxial for as long as Medeco supports the product line.

Can you design a Medeco master key system?

Yes. Master key system design using Medeco hardware for large facilities needing both physical security and key control. Plan documentation, cylinder specification, key coding, and delivery.

More complex than standard master key systems but provides maximum key control.

What about Medeco padlocks?

Yes. Medeco high-security padlocks for gate, container, and outdoor applications. Uses Medeco cylinder technology.

Common for commercial gates, yard security, and container locks where high security is needed.

Can you handle audit and key control reporting?

Yes. Key control records maintained per Medeco authorized dealer requirements. Duplication records, key holder lists, and audit-ready documentation available for customers needing compliance reporting.

Common for schools, hospitals, and government facilities.

How do I know my existing locks are Medeco?

Medeco products have 'Medeco' stamped on the cylinder face and keys typically have 'Medeco' stamped on the bow. Restricted key notation often present. Bring a key or photo to our shop and we can identify the specific Medeco product generation and provide appropriate service.
