Smart Key Replacement FAQ

Can you really program a smart key without the dealership?

Yes. Our technicians carry dealer-level programming equipment and code smart keys to your vehicle's immobilizer at your location. It is our everyday work, not a special order.

I lost every key to my push-to-start car. Is that fixable?

Yes. All-keys-lost programming is more involved but entirely doable at your parking spot. We verify ownership, program a new fob from scratch, and your old lost keys stop working.

How long does it take?

Spare fobs usually take under an hour. All-keys-lost jobs can take longer depending on the vehicle. Either way it is one visit, at your car.

How much does a smart key cost in St. Louis?

More than a basic key, but typically far less than the dealership, with no tow bill on top. Call with your car's details for an exact price, or request a quote online and save 10%.

Which brands can you program?

Most major makes, including Toyota, Honda, Ford, GM, Nissan, Hyundai, Kia, Jeep, and premium brands like BMW, Mercedes, Audi, and Lexus. Tell us your model and we will confirm on the phone.
