Where to Get Keys Duplicated & Which Keys Can't Be Copied

Where You Can Get Keys Duplicated

Most standard mechanical keys can be copied in several places. Hardware stores, big-box home-improvement retailers, and dedicated locksmith shops all offer key duplication services. Many grocery stores and pharmacies also have self-service kiosks that cut basic keys.

For simple house keys that use pin-tumbler or wafer mechanisms, a hardware store or kiosk often works fine. The machines are automated and can duplicate common key blanks in a few minutes. Price typically ranges from $2 to $6 per key.

If you need a high-security key, a transponder car key, or any key marked "Do Not Duplicate," you'll need a professional locksmith. Mobile locksmiths bring the equipment to you, which is especially convenient if you're locked out or need multiple copies cut on-site. A trained locksmith can also verify you own the lock before duplicating restricted keys.

Which Keys Can Be Copied Easily

Standard house keys are the easiest to duplicate. Most residential deadbolts and door knobs use common keyways, Schlage SC1, Kwikset KW1, or Weiser WR5. Any hardware store or locksmith can cut these in minutes.

Basic padlock keys and filing-cabinet keys also fall into the simple category. As long as the locksmith or kiosk has the correct blank, duplication is quick and inexpensive.

Older car keys (pre-1995 for most makes) are purely mechanical and can be copied anywhere that stocks automotive blanks. They have no chip, so programming isn't required.

Keys That Require Special Equipment or Authorization

High-security residential keys, brands like Medeco, Mul-T-Lock, and ASSA, use restricted keyways and require patent-protected blanks. Only authorized dealers can duplicate them, and you'll usually need to show proof of ownership or a key card issued when the lock was installed.

Transponder or chip keys for cars made after the mid-1990s contain an embedded RFID chip that must be programmed to your vehicle's immobilizer. Cutting the blade is only half the job; the chip needs to match your car's security system. A professional automotive locksmith can cut and program these keys, often at a fraction of dealership prices.

Smart keys and key fobs also require programming. These don't have a traditional blade, duplication involves cloning the electronic signal and pairing it with your car. Dealerships and automotive locksmiths handle these, but kiosks and hardware stores cannot.

Some commercial properties use master-key systems or keys stamped "Do Not Duplicate." While the stamp isn't legally binding in most states, reputable locksmiths will ask for authorization or proof of ownership before copying them. This protects building security and limits liability.

Do Not Duplicate Stamps and Legal Restrictions

"Do Not Duplicate" stamped on a key is a request, not a law. In most jurisdictions, a locksmith or key-cutting service can legally copy a key with that marking. However, many professionals refuse out of caution, duplicating a restricted key without permission opens the door to liability if the copy is misused.

Certain government and utility keys are illegal to duplicate under federal or state law. Keys marked "U.S. Government," post-office box keys, and some municipal master keys fall into this category. Attempting to copy them can result in fines or criminal charges.

High-security key blanks that are patent-protected require authorization. The manufacturer controls distribution of blanks, so even if a locksmith wanted to copy your Medeco or Abloy key, they can't without being an authorized dealer and verifying your ownership.

When to Use a Mobile Locksmith Instead of a Kiosk

Self-service kiosks are cheap and fast for basic keys, but they have limits. The machines stock only common blanks, so if you have an unusual keyway or an older lock, the kiosk may not have the right blank. Quality can also vary, automated cutting sometimes leaves rough edges or incorrect depths, and the key may not work smoothly.

A professional locksmith brings precision and flexibility. They can identify uncommon keyways, cut keys by code (useful if you don't have an original to copy), and test the duplicate in your lock before you leave. Mobile locksmiths come to your home, office, or car, so you don't have to remove the lock or make multiple trips to a store.

If you're locked out and need a key duplicated immediately, a mobile locksmith is the fastest option. They arrive with a full key-cutting setup and can rekey your lock on the spot if needed. For residential, automotive, and commercial locksmith services, mobile service eliminates downtime and extra errands.

How to Know If Your Key Can Be Copied

Look at the head of the key. If it's stamped "Do Not Duplicate," "Restricted," or bears a brand name like Medeco or Mul-T-Lock, you'll need authorization and a trained locksmith. If the key has a plastic head with buttons (a key fob) or a visible chip inside, it requires programming as well as cutting.

Check the blade. A standard pin-tumbler key has a series of cuts along one or both edges. Wafer keys (common in file cabinets and some car doors) have cuts on the flat faces. Both types can usually be copied at any hardware store if the keyway is common. Dimple keys, tubular keys, and sidebar keys require specialized equipment, so head to a locksmith.

When in doubt, call a professional. A quick photo or description over the phone can tell you whether a locksmith can duplicate your key and whether they need to come to you. For more guidance, visit our locksmith blog or reach out through our contact page.

Cost and Turnaround Time

Basic key duplication at a hardware store or kiosk runs $2 to $6 per key and takes less than five minutes. High-security residential keys cost $15 to $50 each, depending on the brand and whether you need to show a key card. Turnaround is usually same-day if the locksmith has the blank in stock.

Automotive transponder keys range from $50 to $150 for cutting and programming, compared to $200 to $400 at a dealership. Smart key fobs can run $100 to $300, again significantly less than dealer pricing. Mobile locksmiths often match or beat these rates with the added convenience of on-site service.

If you need multiple copies, for family members, tenants, or employees, ask about bulk pricing. Many locksmiths discount per-key costs when you order five or more at once. Rekeying all your locks to a single key can also be more cost-effective than cutting dozens of duplicates for mismatched locks.
