Bottom line up front: if you don't have a single working key left, that's what the trade calls "all keys lost" — and it's a bigger job than cutting a spare, but it's very fixable. Here's what's actually involved, what drives the cost and time, and what to have ready when you call.
Why it's more than cutting a new key
Your key isn't just a piece of cut metal anymore. Modern vehicles have an immobilizer — the car won't start unless it recognizes a chip inside the key or fob talking to it. Making a working key means programming it to your specific vehicle's immobilizer, not just matching the shape of the old one.
Why "all keys lost" is the harder version
If you still have one working key, a tech can usually add a spare pretty quickly — the car already trusts a key to learn from. With no working key, there's nothing to learn from. So the tech generally has to retrieve the secure immobilizer data for your exact VIN from the automaker (or read it directly from a module) before a new key can be programmed. That extra step is the whole difference between a spare and an all-keys-lost job.
What drives the cost and time
There's no honest flat price, because it depends on:
- Your make, model, and year
- A simple transponder key vs. a proximity/smart fob — smart keys cost more
- Whether the secure code is readily available or has to be requested through the automaker's secured process
- Whether data has to be read off a module on the bench
- How many keys you want cut and programmed
That's why we quote per vehicle instead of posting one number. Tell us the year/make/model and VIN and we'll give you a straight answer.
You'll need to prove the car is yours
Because we're credentialed to pull this secure data, we're required to verify you own the vehicle — a valid photo ID matched to the registration or title and the VIN, plus a signed authorization. That isn't red tape for its own sake; it's exactly what stops someone from having keys made to a car that isn't theirs. Bring your ID and your registration or title.
Dealer vs. a specialist
Straight talk: the dealer usually wants the vehicle towed in and can be slower and more expensive. A specialist who does this work regularly can often handle it more directly. Either way, no one legitimate can make you a key without proof of ownership — if someone offers to, that's a red flag.
How to get started
By appointment at the shop. Call (210) 439-7905 with your year/make/model and VIN, have your proof of ownership ready, and we'll get you scheduled. If the vehicle can't be moved, arrange a tow.
We're at 4715 N Stahl Park, Suite 105, San Antonio, TX 78217.
Year / make / model, the VIN, and proof of ownership (photo ID + registration or title). That's what lets us quote accurately and start without delay.
Curious why your corner shop couldn't just do it?
It's not that they didn't want to — modern key work is gated behind a credential and, on many vehicles, a secure gateway.
