Lost your push-to-start fob? “Key Not Detected” on the dash? We replace and program smart proximity keys on site in Fort Worth for most modern push-to-start vehicles — same day, no dealership tow.
Push-to-start cars use a smart proximity fob that the vehicle detects without you ever inserting a key. Replacing one is more involved than a basic transponder — the new fob has to be paired to the immobilizer with the right diagnostic equipment, and old fobs are usually deleted from the system at the same time so a lost or stolen fob can no longer start the car. We do this on site in Fort Worth.
Most modern push-to-start vehicles have a backup method that lets you start the car when the fob battery dies, but it varies by brand:

Yes. When we program a new fob in an all-keys-lost situation, we typically delete previously paired fobs from the immobilizer so a lost or stolen fob can no longer start the vehicle.
