2010 Audi A4 Smart Key Replacement - Fast, Affordable & Professional
A call came in from Hope Ranch, Santa Barbara. Owner of a 2010 A4, parked in her driveway, push-to-start refusing to see the fob.
She'd already been to another locksmith. Key was cut, key was programmed, everything looked fine for about a week. Then the car started playing games. Start the car in the morning, no problem. Come back in the evening, the start button just sat there blinking at her. She assumed the antennas in the door handles were failing, because that's what the other locksmith told her.
I got there and the first thing I did was sit in the driveway and read the fob. The transponder chip inside had been enrolled, but the data written to it wasn't a clean match for what her immobilizer expected. On this generation of Audi, the system will accept a close-enough key on initial registration and fire the car up fine. Then it runs deeper verification over the next several drive cycles. By day five or six, it had made up its mind and started rejecting the key intermittently, which is worse than a flat-out rejection because it makes you think the car has an antenna issue.
I pulled the fob open right there on the hood. The CR2032 was also borderline. Not dead, just soft enough that combined with the data mismatch, the system was getting inconsistent signals from the fob.
Programmed a fresh key with the correct data matched to her vehicle, confirmed every button function, walked both door handles, and ran the start sequence twice. No drama.
She'd already paid another locksmith. She still paid less than a dealer quote would have cost her, total, for both visits combined.
