Smart Key Programming in Dallas–Fort Worth
Push-to-start? Your car uses a proximity smart key that unlocks and starts just by being near you. When you need a new one programmed, we pair it to your vehicle on site — no dealer trip.

A smart key (also called a proximity key or push-to-start fob) lets you unlock the doors and start the car without ever taking the key out of your pocket. That convenience comes from a constant encrypted handshake between the key and the car — which means a replacement has to be programmed and paired precisely to your vehicle’s system.
We program smart keys on site: the proximity unlock, the push-button start, and the immobilizer pairing that makes it all work. You get a fully functional smart key without the dealership markup or wait.
What smart key programming involves
Smart keys are more involved than a basic remote — we handle:
- Proximity pairing — so the car senses the key for keyless entry and start.
- Push-button start — the immobilizer coding that lets the engine start.
- Remote functions — lock, unlock, trunk, and remote start where equipped.
- Add-a-key or all-keys-lost — whether you’re adding a spare smart key or replacing every one.

Common questions
What’s a smart key versus a regular key fob?
A smart key (proximity key) lets you unlock and start the car without taking it out of your pocket — push-to-start vehicles use them. A regular fob still has physical buttons and often a key you turn. Smart keys take more involved programming, which is why pricing can differ.
How much does smart key programming cost?
You’ll see your exact price in about 60 seconds when you book online — it varies by vehicle, since smart keys differ a lot between makes and models. We confirm the exact price when you book.
Can you add a spare smart key without losing my current one?
Yes — if you still have a working smart key, adding a spare is straightforward and cheaper than an all-keys-lost job. We recommend doing it before you’re down to one.
