Medeco M3 Residential Single Cylinder Deadbolt

Stop lock picking, bumping and unauthorized key copies. The Medeco M3 residential high security deadbolt uses Medeco's patented rotating-pin cylinder with hardened steel inserts, and its keys can only be cut by an authorized Medeco dealer with your key ID card. Classic residential look for homes, condos and rentals.

Why choose the Medeco M3 deadbolt

• Pick and bump resistant: UL 437 listed high security cylinder.
• Drill resistant: hardened steel inserts protect the cylinder.
• Key control: patented, restricted 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. Every new Medeco customer starts here.
• Additional lock, keyed alike to this order ($295): buying more than one? Add your extra deadbolts with this option and they will all open with the same key as your first lock.
• Additional lock, keyed alike to my existing Medeco key ($295): already have Medeco? Text a photo of your key ID card to (818) 723-6800 after ordering.

Example: 3 doors = 1 "First lock" + 2 "Additional lock, keyed alike to this order." Need more keys? Add Medeco Extra Key to your cart. Want it installed? Add Deadbolt Installation.

Choose your backset
