What Is a Smart Key / Push-to-Start System?

A proximity key fob that communicates with the car wirelessly. You walk up to the car with the fob in your pocket. The car senses it and unlocks the doors. You get in, press the start button, and the engine fires. No inserting a key anywhere.

Smart keys use low-frequency radio (125 kHz for proximity detection) and high-frequency radio (315 or 433 MHz for remote lock/unlock). The car and fob exchange encrypted rolling codes. If the codes match, everything works. If the fob is missing or dead, the car won't start.

How Much Does Smart Key Replacement Cost?

$200-$300 for mainstream brands. $300-$450 for luxury brands. Honda, Toyota, Nissan, Hyundai, and Kia smart keys are on the lower end. BMW, Mercedes, Audi, and Lexus are on the higher end because the fob hardware and programming are more involved.

Dealers charge $300-$800 for the same service. The wait at the dealer averages 3-5 business days. We do it same-day at your location. According to a 2025 AAA survey, smart key replacement is the #1 most overcharged service at dealerships.
