Yes, Walmart does copy car keys, but with important limitations. The service is available at most Walmart locations with an Auto Care Center and is primarily for basic mechanical keys. The main advantage is cost savings, often being significantly cheaper than a dealership. However, they cannot program transponder keys or key fobs, which are standard in most modern vehicles. For cars made in the last 15-20 years, a simple key copy will unlock the doors but will not start the engine due to the anti-theft chip.
The process is straightforward. You bring your original key to the Auto Care Center, and a associate will use a key cutting machine to create a duplicate. The service is quick, usually taking just a few minutes. It's an excellent, budget-friendly solution for creating a spare mechanical key for your glove box or for a valet key.
For modern keys, you'll need to visit a specialized locksmith or a car dealership. These professionals have the necessary equipment to clone or program the electronic chip inside the key to communicate with your car's immobilizer system. While more expensive, this is essential for a fully functional key.
| Service Type | Available at Walmart? | Typical Cost (Approx.) | Best For |
|---|---|---|---|
| Basic Mechanical Key Copy | Yes | $2 - $6 | Older cars (pre-~2000), valet keys, door-only spares |
| Transponder Key Programming | No | $50 - $100+ at locksmith/dealer | Most modern cars (post-~2000) for starting the engine |
| Key Fob Replacement | No | $100 - $400+ at locksmith/dealer | Keyless entry remotes |
Before heading to Walmart, check if your key has a small black plastic head; if it does, it likely contains a chip and a simple copy won't start your car. Calling your local Walmart Auto Center ahead of time is always a good idea to confirm their specific services and key blank inventory.

I just went through this. My old Ford pickup has a simple key, and I needed a spare. Walmart did it for under five bucks in five minutes. Super easy. But my wife's newer SUV has one of those fancy keys with buttons. The guy at Walmart told me straight up they can't program those. For that, you have to go to a locksmith, and it cost me over a hundred. So, Walmart is great for basic keys, but not for modern ones.

It's a classic case of "you get what you pay for." Walmart provides a valuable service for basic, pre-chip keys at an unbeatable price. This is perfect for creating a simple door unlock spare or for older vehicles. However, for the vast majority of drivers today, a key is more than just metal; it's an electronic device. For that functionality, you must invest in professional programming, making Walmart a non-starter for modern car key needs.

Think of it like this: Walmart can duplicate the physical shape of your key—the "teeth." That’s the easy part. What they can’t do is clone the tiny electronic chip embedded inside most keys. That chip talks to your car’s computer. No handshake, no start. So, if your key is just metal, you’re golden. If it has a plastic head, you’re only getting half the job done, and it’s the half that won’t get you home.

From a practical standpoint, always check your key first. If it's a thick, all-metal key, Walmart is your most efficient and affordable option. If it's a newer key with a plastic head, save yourself the trip. You'll need a locksmith who specializes in automotive keys or your car's dealership. They have the diagnostic tools to sync the new key's identity with your vehicle's immobilizer system, which is a mandatory step for ignition. The cost is higher, but it's the only solution.
