What’s Included

Everything between “my key is gone” and “I’m driving again.”

Modern car keys are part metal, part computer. The blade has to be cut to your car’s exact code, and the chip inside has to be introduced to the vehicle’s immobilizer before the engine will start. Our mobile workshop carries both halves of that job — cutting machines, key blanks for most makes, and the programmers that speak each manufacturer’s language.

How a replacement visit works

1. Tell us the car. Year, make and model — plus your location — when you call (561) 366-2611. That tells us which blank and programmer your vehicle needs.

2. We schedule and come to you. The appointment is set on the call. Bring a photo ID and proof of ownership (registration or title) — we verify before cutting, every time, because that’s what keeps this service safe for owners.

3. Cut, program, test. We cut the blade to code, program the chip or fob, and test every button and start with you standing there. You pay when it works.

What to have ready

  • The vehicle’s year, make, model and trim if you know it
  • The VIN (dashboard plate or registration) — helpful for all-keys-lost jobs
  • Photo ID and proof of ownership
  • Any remaining key or fob, even a broken one — a fragment can speed things up

A note on dealership vs. locksmith

Dealerships replace keys too — after you get the car to them, during their hours, on their schedule. A mobile locksmith reverses every part of that: we come to the car, our phones are answered around the clock, and the same visit that cuts the key also programs it. For most drivers it’s simply the faster way back on the road. Read more in our lost-all-keys guide.

Car Key Questions

Before you call.

Can you really make a key with no original?

Yes, for most makes and models. We decode the lock or use the VIN to cut a key to the factory code, then program it to the car. Bring ID and proof of ownership — we verify both before cutting.

My fob stopped working — do I need a new one?

Not always. Sometimes it’s a battery, sometimes the fob lost its pairing, sometimes the fob itself failed. Our key fob programming guide explains the three cases; on a visit we test first so you only pay for what’s actually wrong.

Do you program push-to-start smart keys?

Yes — proximity fobs for push-button-start vehicles are a large part of our automotive work. The programmers in our mobile kit cover most major brands.

How do I book?
