Key Duplication: What You Need to Know Before Getting Copies Made

More to Key Copying Than You Think

Most people have gotten a key copied at a hardware store without a second thought. But there are important security, quality, and legal considerations that can affect how and where you should get your keys duplicated.

Standard Key Duplication

Standard mechanical keys can be copied at most hardware stores, home improvement stores, and locksmith shops using an automated key cutting machine. The machine reads the original key's profile and cuts a matching blank. This process takes 2-5 minutes and is inexpensive.

Do-Not-Duplicate (DND) Keys

Many commercial and some residential keys are stamped with 'Do Not Duplicate.' This is a policy restriction — any reputable locksmith or key shop will decline to copy these keys. However, it's not a legal restriction, meaning an unscrupulous shop might still copy them. True security comes from patented key systems, not just the DND stamp.

Patented Key Systems

High-security locks like Medeco, Mul-T-Lock, and ASSA Abloy use patented keyways. Keys can only be duplicated by an authorized dealer with the proper equipment and your explicit authorization. This provides real key control — not just a stamp on the key.

Key Quality Matters

A cheap copy made from a worn original or using a low-quality blank can cause lock problems over time. Professional locksmiths use high-quality key blanks and precision cutting equipment for reliable duplicates.

Transponder and Smart Keys

Modern car keys and many smart home keys contain electronic chips that must be programmed, not just cut. Transponder key duplication requires specialized equipment. Provo Locksmith UT can duplicate and program most transponder and smart keys.
