Can You Duplicate a "Do Not Duplicate" Key?

Keys stamped "Do Not Duplicate" are not legally restricted — they are simply a request by the key manufacturer. Joel Locksmith can cut copies of these keys. However, truly patented and restricted keys (such as Medeco Biaxial, Mul-T-Lock Classic, or BEST PRIMUS) require authorization through the key manufacturer's dealer network, as they have legal patent protection.

Standard Keys — We Can Copy
  • Kwikset, Schlage, Weslock
  • Master Lock, American Lock
  • Most USPS mailbox keys
  • Stamped "Do Not Duplicate" keys
Restricted Keys — Authorization Required
  • Medeco Biaxial and M3
  • Mul-T-Lock Classic and MT5
  • BEST PRIMUS and IC Core
  • Abloy Protec and Disklock Pro

Why Choose Joel Locksmith for Key Cutting?

Hardware stores cut keys too — but they use old, worn-out machines and unskilled staff who often produce keys that don't work on the first try. Joel Locksmith uses professional-grade duplicating equipment maintained and calibrated regularly, and our technicians inspect every copy before handing it over.
