When you need a spare key made, your first instinct might be to swing by the nearest hardware store. But a few minutes of comparison could save you money, time, and headaches—especially if you're dealing with anything beyond a basic door key.
Hardware Stores: Speed and Convenience
Hardware stores like Home Depot, Lowe's, and local independents offer key cutting as a side service, typically at their customer service desk. You walk in, hand over your original key, and walk out with a duplicate in 5–10 minutes. Prices are rock-bottom: expect $1.50 to $4 per standard house or office key. This works perfectly if you need a straightforward copy of a residential door key or a basic padlock key.
The catch? Hardware store staff are generalists. They operate one or two machines designed for the most common profiles. If your key is slightly worn, has an unusual blank, or requires precision, you might end up with a key that binds in the lock or doesn't work at all. Returns are common but still eat your time.
Locksmiths: Specialization and Problem-Solving
A locksmith is a trained technician focused entirely on locks, keys, and security. They operate more sophisticated cutting equipment and can handle specialty keys—automotive, commercial, high-security blanks, keys with security pins, and restricted profiles that hardware stores simply can't touch. If you need a key cut from a photo, or if your original is damaged and worn smooth, a locksmith has the expertise to decode the lock and cut an accurate duplicate.
Locksmiths charge more: $5 to $15 per standard residential key, and $15 to $50+ for specialty cuts. Mobile locksmiths will come to your home or office, adding convenience for commercial clients or when you're locked out. The trade-off is scheduling; you won't get the same five-minute turnaround.
When to Choose Each
Go to a hardware store if:
- You need a basic house or apartment key copied
- You're in a hurry and the key is in good condition
- You want the absolute lowest price
- You're duplicating a common key type (standard Kwikset, Schlage, Master Lock)
Go to a locksmith if:
- Your key is worn, corroded, or damaged
- You need a high-security or restricted key (Medeco, ASSA ABLOY, etc.)
- You require automotive key cutting (requires specialized machines and blank inventory)
- You need keys cut from a lock (no original key available)
- You're duplicating commercial or specialty keys
- You need the job done right the first time—especially for critical access points
What to Check Before You Go
Examine your original key closely. Look for:
- Wear or damage on the blade edges (hardware store cutters may struggle with worn keys)
- Unusual head shape or branding that signals a restricted profile
- Depth marks or security notches beyond a simple straight cut
- Age and material (older keys or brass keys sometimes need softer handling)
If you're uncertain, call ahead. A quick phone conversation with either location takes 60 seconds and tells you whether they can handle your specific job.
The Cost-Benefit Reality
Yes, saving $2 on a key cut matters if you're duplicating five keys. But a failed cut wastes your time and forces a second trip. If your key shows any sign of complexity—or if it's for something you rely on regularly—the locksmith's higher fee is insurance against a bad cut. For commercial properties or master key systems, the difference between a hardware store and a locksmith isn't really a choice: only a locksmith should touch it.

Frequently Asked Questions
Q: Can a hardware store cut high-security keys like Medeco or ASSA ABLOY? No—hardware stores lack the specialized blanks and cutting equipment these restricted systems require. A licensed locksmith is your only option.
Q: How do I know if my key needs a locksmith instead of a hardware store? If the key has an unusual shape, multiple depth levels, security pins visible, or shows significant wear, contact a locksmith first to avoid a wasted trip and a bad cut.
Q: What if I don't have the original key to duplicate? Only a locksmith can help. They'll decode your lock directly using specialized tools and create an accurate key from scratch, a service hardware stores cannot provide.
