Fast, Affordable & Professional Mobile Service
Lost your car keys? Need a spare key made?
You’re in the right place.
At Armstrong Locksmith, we provide professional car key replacement in Nashville, TN, for almost all makes and models — from standard metal keys to modern smart keys and push-to-start systems. We come to you, get the job done right, and save you the hassle and cost of going to the dealership.
Car keys are one part of what we do. See our complete range of automotive locksmith services in Nashville, including ignition repair and broken key extraction. If it is the remote itself that failed, see key fob replacement in Nashville.
We also have pages covering the makes we see most: Honda and Kia key replacement.
Text your VIN. We identify the correct key profile, chip type, and programming frequency before we leave our Thompson Ln shop.
Our mobile workstation arrives at your location. We cut the physical blade and program the fob to your vehicle’s security system on-site.
We test every button—lock, unlock, trunk, and remote start—to ensure the key is fully authorized by your car's immobilizer.
For the fastest response in Nashville, have these 3 details ready when you reach out:
Note: If you've lost all keys, we can still decode and cut a new one from scratch.
Replacing a modern car key is not the same as cutting a spare at a hardware store. Almost every vehicle built in the last 20 years pairs a cut blade with a transponder chip or a proximity fob that has to be programmed to your car's immobilizer before the engine will start. At our Thompson Ln shop we handle both halves of that job in house: we cut the blade to your lock, then program the chip through the OBD port or, when a vehicle needs it, by reading the immobilizer data directly.
If you have lost every key and there is no working original, we can still generate a new key from the vehicle itself. That all key lost situation takes longer and costs more than adding a spare, so it helps to tell us which situation you are in when you call.
We cut and program keys for almost every make on the road, whether it is domestic, Asian, or European. The common types we handle are:
Several makes have their own page with model detail: Toyota, Honda, Kia, BMW, Mercedes, Audi, and other European car keys. If your make is not listed, call 615-625-8000 and we will tell you honestly whether we can do it same day.
Price depends on your vehicle. A basic transponder key for an older sedan is one of the cheapest jobs we do, while a proximity fob for a late model luxury vehicle costs more because the fob itself is expensive and the programming is more involved. The biggest single factor is whether you still have a working key: adding a spare is quicker and cheaper than an all key lost job where we originate a key from scratch.
In almost every case we come in well under what a dealership charges, and we do not tow your car to do it. You can see typical ranges on our Nashville locksmith pricing page, or call for a firm quote on your exact year, make, and model.
We are one of the few Nashville locksmiths with a real storefront, at 208 Thompson Ln. You can drive in, or we can come to you at home, at work, or wherever your car is stranded. Mobile service is ideal for a lockout or an all key lost job where the car cannot be moved, while bringing the car to the shop is often the fastest route for a straightforward spare. Either way you are working with the same licensed technicians and the same equipment.
Armstrong Locksmith has been cutting and programming car keys in Nashville for 20 years. We are a licensed Tennessee locksmith, license number 406, run by owner Rahim with technicians Kawa and Sako. When you call our number you reach the shop, not a national call center that farms the job out to whoever is nearest.
That difference matters, because dispatch centers are the main source of the price gouging and no show complaints you read about online. We wrote a full guide on how to tell a real Nashville locksmith from a dispatch center if you want to know what to watch for. We will also be straight with you about the rare cases we cannot solve same day, usually a handful of very new models where the dealer still controls the key data.
Can you make a car key with no original?
Yes. If every key is lost we can originate a new one from the vehicle. It takes longer than a spare, so let us know when you book.
How long does it take?
Most spare keys are done in 20 to 45 minutes once we are with the car. All key lost jobs and some European models take longer.
Do you come to me?
Yes. We offer mobile service across Nashville and the surrounding areas, and we also have a walk in shop on Thompson Ln.
Will a new key affect my existing keys?
Adding a key does not disable your other working keys. In an all key lost job we reset the system, which does erase any keys that are not present.
How can I pay?
We accept cash and all major cards, plus Venmo and Cash App. See our payment methods page.
