🔧 PRO TIP
The 2009 S4 remote flip key runs on a CR2032, but the battery is only half the story. If the fob stops working at range but still works when you hold it close to the door handle, that is a classic sign the battery is weak, not dead. Swap it before assuming the fob itself is bad. Also worth knowing: if both keys stop responding at the same time, that almost never means two bad fobs. That points to something on the vehicle side, either the antenna ring, the receiver module, or a power supply issue feeding the immobilizer. We scan the car first before cutting anything new.

2009 Audi S4 Remote Flip Key Replacement - Fast, Affordable & Professional

A software engineer working out of an office in Otay Mesa West watched his S4 key disappear into a storm drain. Not dropped in a puddle, not left on a desk. Gone. Into the drain, in the parking lot, during the middle of a product launch week.

He had standups at 9am and a live demo at 3pm. He could not leave the car, could not schedule a tow during business hours, and could not sit in a dealer waiting room for half a day even if he wanted to. He found me through a search and called before lunch.

I drove to his office lot and got to work. The 2009 S4 flip key is a 3-button remote with the transponder built into the key head. The programming goes through the OBD port using professional-grade diagnostic equipment that talks directly to the immobilizer. I ran the full procedure, enrolled the new key, and tested every button before handing it over. The whole job was done in the lot while he stepped outside for maybe twenty minutes.

He made his afternoon demo. His car never left its parking spot. The dealer would have needed him to tow the car in, schedule days out, and wait on parts. That route was not an option for him, and honestly it should not have to be.

Audi S4 Mobile Service FAQ

Real costs, no dealer surprises

What if I need an Audi key after hours or on the weekend?
Call us. Audi dealer service departments run Monday through Friday with limited Saturday hours and typically no Sunday availability. Lose your only key on a Friday evening and you are looking at Monday at the earliest, assuming they have a blank in stock and an open appointment. Owners on Audi forums describe waiting several days just to get on the schedule, and that wait starts after the tow gets the car there. We work nights and weekends because that is exactly when people discover they need a key.
How long does the programming actually take once you are at my car?
Can you make a key faster than the dealer?
I bought a replacement fob online. Can I program it myself or do I need someone with equipment?
My key turns and the engine cranks but then immediately stalls. Is that an immobilizer problem?
