Medeco M3 Commercial Single Cylinder Deadbolt — Grade 1

Built for storefronts, offices and multi-unit buildings. The Medeco M3 commercial high security deadbolt is UL 437 listed and ANSI/BHMA Grade 1, with a 6-pin Medeco M3 cylinder, hardened steel inserts and a 1" hardened steel bolt. Patented key control means keys can only be cut by an authorized Medeco dealer with your key ID card.

Why choose the Medeco M3 commercial deadbolt

• Grade 1 strength: solid brass body, free-turning collar and 1/4" mounting bolts resist wrenching and prying.
• Pick, bump and drill resistant: UL 437 listed cylinder.
• Key control: restricted 6-pin M3 keys that hardware stores cannot copy.
• Single cylinder: key outside, thumbturn inside.

How to order (keying)

• First lock ($330): comes pinned with 2 keys and your Medeco key ID card.

• Additional lock, keyed alike to my existing Medeco key ($295): text a photo of your key ID card to (818) 723-6800 after ordering.

Choose your backset
