Yes, Home Depot copies car keys, but with significant limitations. The key copying service at their key cutting kiosks is primarily designed for traditional, basic car keys that lack electronic components. If your car key is a simple metal key without a chip (commonly found in older vehicles), Home Depot can likely duplicate it. However, they generally cannot copy modern transponder keys, key fobs, or laser-cut keys due to the specialized programming equipment required.
The process is straightforward. You use a self-service kiosk, like the Minute Key kiosk, which guides you through the steps. You insert your original key, and the machine cuts a new one. It's a quick and affordable option, often costing between $2 and $6 for a basic key copy.
Crucial Limitations to Consider:
For a simple spare key for an older car, Home Depot is a convenient and cost-effective solution. For any modern vehicle, you're better off visiting a locksmith specializing in automotive keys or your car dealership to ensure full functionality.

I tried to copy my Honda key at Home Depot last year. The kiosk made a physical copy just fine, but when I got to my car, it wouldn't start. Turns out my key has a chip in it. The guy at the store said they can't program those. I ended up having to call a mobile locksmith. It was a hassle. So, they can copy the metal part, but if your car is from this century, it probably won't work to start the engine.

As a quick tip, Home Depot is great for duplicating standard house keys or a simple, old-fashioned car key. Think of the basic key for a 1995 pickup truck. For anything more complex—like a key with buttons on it or one that’s thick and plastic—you’ll need to go elsewhere. Their kiosks are automated and can't handle the electronic side of modern car keys. Always check what type of key you have before you go.

It really depends on what you mean by "car key." If it's the valet key or a simple spare for an older model car that you just need to unlock the door, then yes, Home Depot can do it cheaply. But if you need a fully functional key that starts the car, the answer is usually no for most modern vehicles. The convenience is tempting, but the risk of getting a key that only works for the door isn't worth the trip for most people today.

From a cost perspective, Home Depot is the cheapest option by far if your key is compatible. A basic copy costs a few bucks, while a locksmith or dealership can charge $100 to $400. The trade-off is capability. Their service is designed for volume and simplicity, not for the sophisticated technology in today's keys. It’s a perfect solution for a shed or cabinet key, or that old car you use as a beater, but not for your primary daily driver.
