🔧 PRO TIP
The 2001 Audi S4 uses a remote flip key with a transponder chip that has to be matched to the immobilizer before the car will run. The fob and the ignition authorization are two separate things. A used fob you find online might lock and unlock the doors after syncing, but if the transponder isn't enrolled in the immobilizer, the car cranks and dies every time. Both halves need to be handled together. Also worth knowing: the flip key blade on these wears at the pivot hinge over time. If the blade feels loose or the hinge pin is walking out, the key can cut out mid-drive when vibration breaks contact with the transponder coil. Don't sleep on a wobbly hinge.

2001 Audi S4 Remote Flip Key Replacement - Fast, Affordable & Professional

I got a call from a guy in West Santee, over near the older industrial pocket off Prospect Avenue. He was in a parking structure attached to his office building and his 2001 Audi S4 wasn't going anywhere. The flip key blade had physically snapped at the hinge pivot, which happens on these after enough years of being grabbed wrong out of a tight pocket. Half the blade was still in the ignition cylinder and the other half was in his hand.

The parking structure had a low clearance on the entry ramp, which meant the tow truck the dealer suggested was a non-starter. They told him to call back when the car was at the dealership. That was their answer to a man standing in a parking garage holding a broken key.

I drove into the lot, parked one level up, and walked down with my bag. Extracted the broken blade from the cylinder using a thin extractor, no drama. Cut a new blade to match his vehicle and assembled the flip mechanism. Then connected to the OBD port, read the immobilizer data, and enrolled the transponder so the car would actually start and not just crank.

I tested every button, confirmed the remote synced, started the car twice. He drove out of that garage about forty-five minutes after I arrived. The dealer was still waiting on a callback.

He mentioned what the dealer had quoted him over the phone, not including labor to extract the broken blade. He paid a fraction of that, and I came to him.

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 availability and nothing on Sunday. If your only key fails on a Friday evening, you are looking at Monday at the earliest, and that assumes they have the correct fob blank in stock, which for a 2001 S4 is not guaranteed. Owners on forums routinely describe being told parts need to be ordered before any programming appointment can even be booked. We work nights and weekends specifically because that is when keys fail and people are stuck.
How long does the programming take once you are at my car?
Can you make a key faster than the dealer?
My S4 cranks but immediately stalls. The key is in my hand. What is happening?
The remote buttons stopped working but the car still starts fine. Do I need a whole new fob?
