Car key copying costs between $3 and $30 for a basic metal key, and $50 to $500 for a modern key with a chip or remote functions
The price depends on what kind of key you need copied. A straightforward metal key from a hardware store costs the least. A key with a built-in chip that communicates with your car's ignition system costs more. A key fob that locks and unlocks your doors remotely costs the most. Where you go matters too — a big-box hardware store, a car dealership, and a locksmith will each charge differently for the same key.
The age and make of your car affects the price. Older cars with basic keys are cheaper to copy. Newer cars with security features built into the key are more expensive. Some dealerships charge by the hour for programming, which can push the cost higher if the job takes time.
Key Takeaways
- A basic metal car key costs $3 to $10 at a hardware store, but may not start your car if it has a security chip.
- A key with a transponder chip (which most cars made after 2000 have) costs $50 to $200 to copy and program, depending on your car's make and year.
- A key fob with remote lock and unlock buttons costs $100 to $500 to replace, and dealerships are usually the only place that can program them.
- Locksmiths are often cheaper than dealerships for chip keys but may charge a service call fee on top of the key cost.
- Getting a spare key made before you lose your only one saves money, because emergency key replacement often costs more.
Basic metal keys from hardware stores
A plain metal key with no electronics costs $3 to $10 at most hardware stores, locksmiths, and big-box retailers. Stores like Home Depot, Lowe's, and Ace Hardware have key-cutting machines and can copy a key while you wait, usually in under five minutes. You hand them your original key, they cut a blank to match, and you pay at checkout.
The catch: this key will open your car door and turn the ignition cylinder, but it will not start the engine if your car has a security system. Most cars made after 2000 have a transponder chip inside the key head — a tiny computer that talks to the car's ignition system. A plain metal copy will turn in the lock but the engine will not turn over. You need the chip to start the car.
A hardware store key is useful as a backup for opening a locked door or for a spare you keep at home, but it is not a working replacement key for driving the car.
Keys with transponder chips
A transponder key has a small chip embedded in the plastic head that sends a coded signal to your car's computer. When you insert the key and turn it, the car checks that the signal matches. If it does, the engine starts. If it does not, the engine stays off — this is the car's anti-theft system.
Copying a transponder key costs $50 to $200, depending on your car's make, model, and year. The cost includes both cutting the physical key and programming the chip to your car. A locksmith usually charges $50 to $150. A dealership usually charges $100 to $200. The difference is that a dealership has the exact programming equipment for your specific car model, while a locksmith uses a universal programmer that works across many brands.
You will need your original key or proof of ownership (like your registration or title) to get a new transponder key made. Some locksmiths and dealerships will program a key without the original if you show ID and proof that you own the car, but policies vary. Call ahead to ask what they need.
Key fobs and remote keys
A key fob is a remote control that locks and unlocks your car doors and sometimes opens the trunk. The fob contains a transmitter that sends a wireless signal to your car. Some fobs are separate from the key; others are built into the key itself. Replacing a fob costs $100 to $500, depending on the brand and features.
A dealership is usually your only option for a key fob, because the programming is specific to your car's make and model. Locksmiths sometimes program fobs, but not all of them have the equipment. Call your car's dealership first — they can tell you the cost and whether they have fobs in stock. If they do not, they can order one, which usually takes a few days to a week.
Some newer cars have a smart key or keyless entry system where you push a button to start the car instead of turning a key. These cost $200 to $500 to replace and must be programmed by the dealership.
Dealership versus locksmith pricing
A dealership charges more than a locksmith for the same key, but they have the exact equipment and software for your car. A dealership typically charges $100 to $200 for a transponder key, while a locksmith charges $50 to $150. For a key fob, a dealership might charge $200 to $500, while a locksmith (if they offer the service at all) might charge $150 to $300.
A locksmith may also charge a service call fee of $50 to $100 if you call them to your home or car. A dealership does not usually charge a service call fee, but you have to go to their location during business hours. If you are locked out of your car and need a key made on the spot, a locksmith's convenience may be worth the extra cost.
Before you choose, call both and ask for a quote. Tell them your car's year, make, and model, and what kind of key you need. Ask whether the price includes programming and whether there are any extra fees. Some locksmiths offer lower prices but may take longer or require you to leave your car with them while they work.
What affects the total cost
The year your car was made is the biggest factor. Cars from the 1980s and 1990s often have straightforward keys that cost $5 to $20 to copy. Cars from 2000 onward almost always have transponder chips, which cost more. Luxury brands like BMW, Mercedes, and Audi have more complex security systems and charge more to copy keys — sometimes $200 to $400 for a single key.
Whether you have the original key matters. If you do, copying is faster and cheaper because the technician just needs to cut and program a match. If you do not have the original, they have to reprogram your car's system to accept a new key, which takes longer and costs more. Some dealerships charge an extra $50 to $100 for this service.
The number of keys you order at once can affect the price. Some locksmiths and dealerships offer a small discount if you order two or three keys together instead of one. Ask about this when you call for a quote.
How to save money on car keys
The cheapest time to copy a car key is before you lose your only one. Get a spare made while you have the original — this costs the standard rate and takes minutes. Keep the spare in a safe place at home, not in your car or wallet.
If you lose your only key, you will pay more. You will have to go to a dealership (most locksmiths cannot reprogram a car without an existing key), and the dealership will charge extra for the reprogramming work. This can cost $150 to $400 instead of $100 to $200.
Shop around before you commit. Call at least two locksmiths and your car's dealership. Ask each one for a full quote that includes cutting, programming, and any service fees. Prices vary widely, and a five-minute phone call can save you $50 to $100.
Frequently Asked Questions
Can I copy my car key at any hardware store?
You can get a basic metal key cut at any hardware store, but it will not start your car if it has a security chip. For a key that actually works, you need a locksmith or dealership that can program the chip.
What do I do if I lost my only car key?
Call your car's dealership first. They can make a new key and reprogram your car to accept it, but this costs more than copying a key when you have the original — usually $150 to $400. A locksmith may be cheaper, but call ahead to confirm they can reprogram without an existing key.
How long does it take to copy a car key?
A basic metal key takes 5 to 10 minutes at a hardware store. A transponder key takes 30 minutes to an hour at a locksmith or dealership. A key fob may take a few days if the dealership has to order it.
Will my car insurance cover a lost key?
Most car insurance policies do not cover lost or stolen keys. Check your policy or call your insurance company to be sure. Some roadside information programs (like AAA) cover locksmith fees, so check whether you have that coverage.
Can a locksmith copy a key fob?
Some locksmiths can program key fobs, but not all have the equipment. Call ahead and describe your car's year, make, and model. A dealership is the safest choice if you need a fob programmed.
