Where to get a replacement key depends on your car's age and key type

You have three main routes: a dealership, a locksmith, or a big-box retailer like Home Depot or Walmart. Which one works best depends on whether your car has a basic metal key, a key fob with buttons, or a smart key that communicates with the car's computer. Dealerships charge the most but handle every key type. Locksmiths are usually faster and cheaper for older cars. Retailers split the difference on price and work for many common vehicles, but not all.

The fastest option is often a mobile locksmith who comes to you, though you'll pay a service call fee on top of the key cost. If you're locked out of your car right now, that's your best bet. If you have time and your car is still under warranty, the dealership might replace a lost key for free or at a reduced cost — check your paperwork first.

Key Takeaways

  • Dealerships work on any car but charge $200 to $500 for a key fob or smart key, while locksmiths typically charge $50 to $200 depending on the key type.
  • You'll need your vehicle identification number (VIN), proof of ownership like your registration or title, and a photo ID to get a replacement key from any provider.
  • Basic metal keys take 15 minutes to cut at a retailer; key fobs and smart keys take 30 minutes to an hour and may require programming at a dealership.
  • Mobile locksmiths can meet you at your car or home but charge a service call fee ($50 to $100) on top of the key cost.
  • If your car is newer and uses a smart key, the dealership is often your only option because the key must be programmed to your specific vehicle's computer.

Gather your documents before you contact anyone

Have your VIN ready — it's on your registration, insurance card, or the driver's side dashboard. You'll also need proof of ownership, which means your registration, title, or insurance card. Bring a photo ID. Some providers ask for these over the phone; others need them in person. Having them ready speeds up the process.

If you don't have your registration handy, you can find your VIN on your insurance card or by looking at the metal plate on the driver's side of the dashboard where it meets the windshield. Write it down before you call. The VIN tells the provider what kind of key your car uses and whether it needs programming.

Dealership: the most expensive but most reliable option

Call your car's dealership and ask for the parts or service department. Tell them you need a replacement key and give them your VIN. They'll tell you the cost and how long it takes — usually one to three business days if they have to order the key, or same-day if they stock it. Bring your registration and ID when you go in.

Dealerships charge the most because they program the key to your car's computer system, which is required for any key with a fob or smart features. For a basic metal key, expect $50 to $150. For a key fob, expect $150 to $300. For a smart key on a newer car, expect $200 to $500. Some dealerships offer roadside information or will replace a lost key free if you're still under warranty — ask when you call.

Locksmith: faster and cheaper for most vehicles

Search for "automotive locksmith near me" or "car locksmith [your city]" and call three or four shops for quotes. Tell them your car's year, make, model, and what kind of key you need. A basic metal key costs $15 to $50 to cut. A key fob costs $75 to $200 depending on whether the locksmith has to program it. A smart key usually requires a dealership, but ask anyway — some locksmiths have the equipment.

Locksmiths are faster than dealerships for straightforward keys and often work on weekends or evenings. Many offer mobile service, meaning they come to your car or home. You'll pay a service call fee of $50 to $100 on top of the key cost, but you avoid a trip to the dealership. Check reviews on Google or Yelp before you call — look for shops that have been in business for at least three years and have mostly five-star ratings.

Retailers: a middle ground for common vehicles

Home Depot, Walmart, and some Ace Hardware locations cut car keys in-store. Go to the key-cutting counter and tell them you need a car key. They'll ask for your VIN or your car's year, make, and model. Basic metal keys cost $2 to $10 and take 15 minutes. Some retailers also cut key fobs for $50 to $150, but they can't program smart keys.

The advantage is speed and low cost for straightforward keys. The disadvantage is that they don't program key fobs or smart keys, so if your car requires programming, you'll have to take the key to a locksmith or dealership afterward. Call ahead to confirm they cut keys for your car's year and model — not all retailers stock blanks for every vehicle.

What happens after you get your replacement key

If you got a basic metal key, you're done — it works when ready. If you got a key fob or smart key, the provider will have programmed it before you leave. Test it in the car to make sure the buttons work and the car recognizes it. If the key doesn't work, go back to the provider the same day and ask them to reprogram it.

Keep your receipt and the new key in a safe place. If you lose this key too, you'll have an easier time the second time because you already know where to go. Consider hiding a spare key in a find lockbox at home or giving one to a trusted friend or family member — it's cheaper than paying for another replacement.

Do I need to reprogram my car's computer after getting a new key?

The locksmith or retailer programs the key before you leave. You don't need to do anything else. Test the key in your car to make sure it works. If it doesn't, go back to the provider the same day and ask them to reprogram it at no extra charge.
