Several types of businesses can make replacement car keys. Your primary options are the dealership for brand-specific service, a local locksmith for often faster and more affordable service, and some auto parts stores that offer basic key cutting. The best choice depends heavily on your car's age, the type of key you have (traditional, transponder, fob, or smart key), and your urgency and budget. For modern keys with electronic chips, programming is required, which is a specialized process.
For older cars with simple metal keys, a local hardware store might suffice. However, most vehicles from the mid-1990s and newer use transponder keys (chip keys) that must be programmed to communicate with your car's engine immobilizer system. This is where the decision gets important. Dealerships have the proprietary software and codes for your specific model but are typically the most expensive option. Independent auto locksmiths, especially those with mobile services, can usually program keys for a wider range of models at a lower cost.
Here’s a quick comparison of common providers:
| Service Provider | Typical Cost Range (Basic Transponder Key) | Service Time | Key Programming Capability | Best For |
|---|---|---|---|---|
| Car Dealership | $200 - $500+ | Often requires an appointment | Full capability for all models | Newest models, complex smart keys, if other options fail |
| Mobile Auto Locksmith | $100 - $250 | Often same-day, on-site service | High capability for most models | Best balance of cost and convenience for most modern keys |
| Auto Parts Store (e.g., AutoZone) | $20 - $100 (for cutting only) | While-you-wait | Usually limited or none | Duplicating a simple, existing key; programming is a separate task |
| Hardware Store (e.g., Home Depot) | $5 - $50 | While-you-wait | None | Pre-1990s vehicles with no electronics |
Before you call, have your Vehicle Identification Number (VIN) and proof of ownership ready, as these are required to legally obtain a key that can be programmed to your car. If you have a spare key, it can significantly reduce the cost and complexity of the replacement.

Honestly, just Google "mobile auto locksmith near me." That's your best bet for a balance of speed and cost. They come to you, whether you're at home or stranded in a parking lot, and can handle the electronic programming for most cars right on the spot. It's almost always cheaper and faster than dealing with a dealership, unless you drive a very new or exotic model. Just make sure you have your driver's license and vehicle registration to prove you own the car.

If it's an older car without any buttons on the key, you can probably get a copy made at a hardware store for a few bucks. But for anything modern, the key has a little chip in it that talks to your car. You'll need a specialist. I tried doing it myself with a kit I bought online, and it was a huge headache. It's worth paying a pro—an auto locksmith—to get it done right the first time without the guesswork.

I recently went through this. Called the dealership first, and they quoted me over $400 and said I'd have to tow the car there. I found a highly-rated local locksmith instead. He was at my office in under an hour, programmed a new key fob in my driveway for about half the price, and I was back on the road. My advice is to always get a couple of quotes. The dealership isn't your only option, and it's rarely the best one for a simple key replacement.
