Yes, you can get a basic car key copied at many Home Depot locations, but there are significant limitations. The service is primarily for traditional, mechanical keys without any electronic components. If your car is from the mid-1990s or newer, it likely uses a transponder key or a key fob, which Home Depot's key-cutting kiosks cannot program or duplicate. For those, you'll need a dealership or a specialized locksmith.
The key-cutting service at Home Depot is typically done at a Minute Key kiosk or by an associate at the hardware aisle. The process is quick and affordable for standard keys. However, the crucial factor is the type of key you have. A simple metal key that only operates the door and ignition lock cylinder is a good candidate. A transponder key, which has a small chip inside that communicates with your car's immobilizer system, requires programming to start the engine. Simply cutting a copy of its shape will not work.
Here’s a quick comparison of key types and where to get them copied:
| Key Type | Description | Can Home Depot Copy It? | Where to Go Instead |
|---|---|---|---|
| Traditional Mechanical Key | Basic metal key, no electronics. Common in pre-1990s vehicles. | Yes, at a kiosk or service counter. | Home Depot, Lowe's, hardware stores. |
| Transponder Key | Contains a chip that must be programmed to the car. Standard since mid-1990s. | No, they can cut the blade but not program the chip. | Dealership, automotive locksmith. |
| Laser-Cut Key | Higher-security key with a distinct, complex cut. Often used with transponders. | No, specialized equipment is required. | Dealership, specialized locksmith. |
| Smart Key / Key Fob | Keyless entry fob with a push-to-start button. | No. | Dealership is the most reliable option. |
Before heading to Home Depot, examine your key. If it’s a thick plastic-headed key, it almost certainly has a transponder. The most reliable approach is to call your local Home Depot and ask if their key-cutting service can handle your specific car's make, model, and year. For modern keys, an automotive locksmith is often the most cost-effective and convenient solution compared to the dealership.

I tried it last month for my old Ford pickup. It worked perfectly and only cost about five bucks. The guy at the kiosk did it in two minutes. But he told me straight up it only works for basic keys, nothing with a chip. If your key has a big plastic head, you're probably out of luck. For a simple spare, it's a great deal.

As a general rule, Home Depot is a solution for duplicating a simple key, not replacing a modern car key. Their machines copy the physical cut of the key. The issue is that most cars made in the last 25 years have an anti-theft immobilizer system. This requires syncing a new electronic chip to your car's computer, which their kiosks cannot do. You'll end up with a key that unlocks the door but won't start the engine.

I think of it like this: Home Depot is for your house key, not your car key. My son lost the key to his 2012 Honda, and we went to Home Depot first. They cut a new one, but it was useless because it needed programming. We ended up having to call a mobile locksmith anyway. It was an expensive lesson. Save yourself the trip unless you're sure your car is really old.

It depends entirely on your vehicle's age. For an older classic car with a basic metal key, yes, it's a fast and cheap option. For any modern vehicle, the answer is a definitive no. The technology in today's keys is comparable to a small computer, designed for security. The programming process is proprietary and requires specialized diagnostic tools that only dealerships and certified locksmiths possess. Home Depot simply doesn't offer that level of service.
