Call five locksmiths in Louisville about a replacement car key and you will get five numbers, some of them ten times apart. That is not because four of them are lying — it is because "car key" describes at least six genuinely different products, and the person quoting you $19 is quoting a different one from the person quoting you $600.
Here is what actually drives the price, what a fair number looks like in this market, and how to spot the quote that is going to change when the van arrives.
The six kinds of car key
Price tracks key type more than anything else. Find yours on this list and the range stops looking random.
| Key type | Roughly what it is | Typical Louisville range |
|---|---|---|
| Basic metal key | No electronics. Pre-1998 vehicles, plus modern trunk and glovebox keys. | $15 – $50 |
| Transponder key | Metal blade with a chip in the head. The chip has to be programmed to the car. | $120 – $260 |
| Remote head key | Transponder key with the lock/unlock buttons built into the head. | $150 – $300 |
| Laser-cut / sidewinder | Thicker blade with a milled track down the center. Needs a milling machine, not a duplicator. | $180 – $340 |
| Proximity smart key | Stays in your pocket. Push-button start. Domestic and Asian. | $220 – $480 |
| European smart key | Same idea, far more protected. Mercedes, BMW, Audi, Land Rover, Volvo. | $350 – $950 |
If you do not know which you have, the shortcut is: does your car have a push-button start? Then it is a proximity smart key. Does the key have a plastic head noticeably thicker than the metal needs to be? Then there is a chip in it.
The second variable: do you still have a working key?
This is the one most people do not know about, and it moves the price more than almost anything else.
If you still have one working key, a locksmith can read it and add a second alongside it. Fast, cheap, low risk. If every key is gone — what the trade calls all-keys-lost — nobody can read anything, and the security data has to be extracted from the vehicle itself. On some platforms that means removing a module and working it on a bench.
| Scenario | Domestic / Asian | European |
|---|---|---|
| Adding a spare (you have a working key) | $95 – $300 | $240 – $520 |
| All keys lost | $220 – $480 | $450 – $950 |
What else moves the number
- Time of day. Overnight, Sunday, and holiday calls carry a surcharge. It should be quoted before dispatch, never added at the end.
- Distance. A call in Shelbyville costs more than one in St. Matthews because someone drives an hour each way.
- Erasing lost keys. After a theft you want the missing key wiped from the vehicle's memory. Some shops charge separately for this. It should be included.
- The emergency blade. Every smart key hides a mechanical blade for when the battery dies. Cutting it to your door lock is part of the job, not an upsell.
- Programming-only jobs. If you supply your own fob, you pay labor only — but you carry the risk that the fob will not accept programming.
Locksmith versus dealership
For key work specifically, an equipped mobile locksmith is usually 30 to 50 percent below dealer pricing, and that is before the tow. A car with no working keys cannot be driven to a dealership, so the dealer route means a tow bill and a service appointment that may be several days out.
That said, the dealer is genuinely the right answer sometimes. A small number of very recent models have key programming restricted to franchised dealers with no aftermarket access. An honest locksmith tells you that on the phone rather than charging a service call to discover it.
How to spot a quote that will change
The bait-and-switch pattern in this industry is well documented and it works like this: a very low number gets quoted on the phone, a technician arrives, and the price multiplies once your car is apart or you have already waited an hour.
- A price quoted without your vehicle details is not a price. Anyone who quotes before asking your year, make, and model is quoting a number designed to get a van to your location, not to describe your job.
- "Starting at $19" is an advertising figure, not an offer. It usually refers to a service call fee, with the actual work priced separately once they arrive.
- Ask for the total, out the door, including the call-out. Then ask what would make it change. A straight answer is a good sign.
- Ask where the company is based. A national call center that dispatches an unvetted subcontractor is the structure most complaints come from.
- Expect to be asked for ID. A locksmith who does not verify ownership is a locksmith who will open your car for someone else.
What we charge, plainly
We quote a firm number on the phone once we have your year, make, model, and ideally the VIN. That number includes the call-out, the key, the cutting, and the programming, and it does not change when we arrive. If we get there and the job turns out to be genuinely different from what was described, we re-quote before touching anything and you are free to decline.
Our published ranges are on the pricing page, and they are ranges rather than a single number for the honest reason that a 2009 Civic and a 2023 Range Rover are not the same job.
