Getting a key duplicated shouldn't drain your wallet, yet many people overpay by defaulting to their local hardware store without comparing options. The price difference between cutting a basic house key at a big-box retailer versus a dedicated locksmith can be anywhere from 50 cents to several dollars per key. Here's where to find the most affordable duplication services and what factors actually affect the final cost.
Hardware Stores: The Accessible Mid-Range Option
Home Depot, Lowe's, and Ace Hardware operate key-cutting kiosks in most locations, making them convenient for quick duplications. Expect to pay $1.50 to $3.00 for a standard house key, with prices climbing to $4.00 to $6.00 for specialty keys like car fobs or mailbox keys. Many of these stores also offer bulk discounts—buying five keys instead of one typically reduces the per-key cost by 15–25%.
The main advantage here is predictable pricing and minimal wait times. However, quality can be inconsistent; some machines are calibrated better than others, meaning your duplicate might occasionally stick or require filing.
Locksmiths: Variable But Often Competitive
Independent locksmiths frequently undercut big-box stores on simple keys. A local locksmith might charge $1.00 to $2.50 per basic house key, but you'll pay more for emergency calls (typically $50–$150 just for the visit) or rush jobs. For residential work without urgency, calling ahead for pricing usually saves money.
The advantage is precision—locksmiths use professional-grade equipment and often catch problems that automated kiosks miss. They're also your only option for damaged originals or severely worn keys.
Dollar Stores and Discount Retailers
Dollar General, Five Below, and similar discount chains often have key-cutting services at rock-bottom prices: $0.99 to $1.99 per key. This is genuinely the cheapest option for basic cuts. The trade-off is limited customization; they handle standard residential and padlock keys only, and don't typically work on automotive or high-security blanks.
Quality here is the real gamble. Some locations use older equipment, and staff training varies widely. Test the key thoroughly before leaving the store.
Walmart and Superstores
Walmart operates key-cutting services in many locations at $1.48 to $2.50 per basic key. While prices sit between discount stores and hardware chains, Walmart's advantage is extended hours—many cut keys until 9 or 10 p.m., convenient for after-work stops.
What Affects Key Cutting Costs
Type of key is the primary price driver:
- Standard house/padlock keys: $1–$3
- Car keys (mechanical only, no chip): $3–$8
- Car key fobs with transponders: $8–$20+
- Mailbox or cabinet keys: $2–$4
- High-security keys: $5–$15
Rush timing adds 25–50% to any price. Quantity typically gets you volume discounts at 5+ keys. Key condition matters too—if your original is badly worn, locksmiths may charge extra to hand-cut from scratch rather than use a machine.
Smart Shopping Strategy
Get the original key tested in the lock before paying anything. Take it to at least two locations and ask for quotes—prices vary by vendor and branch. If you need multiple keys regularly (rental property management, business access), negotiate bulk rates with a single locksmith.
For specialized keys (automotive, high-security), skip discount retailers entirely. You'll either get a non-functional copy or be charged extra when the basic machine can't handle it. Locksmiths or dealerships (for car keys) are your reliable bet.

Frequently Asked Questions
Q: How long does key duplication typically take? Most standard keys are cut within 5–10 minutes at hardware stores and discount retailers; locksmiths usually take 10–15 minutes for basic work but may need 24–48 hours for specialty or high-security keys.
Q: Can you duplicate a key without the original? No—locksmiths can sometimes create a key from a lock itself, but they'll charge $25–$75 for that specialized service and can't use standard cutting machines.
Q: Is there a warranty if the duplicated key doesn't work? Hardware stores and locksmiths typically offer free re-cuts if the key fails immediately, but this must be done within the same visit or within a day.
