🔧 PRO TIP
The 2010 S4 runs the Megamos 48 chip (CAN variant) inside a 3-button flip key with an HU66 blade, part number 4F0 837 220. The immobilizer is IMMO3/IMMO4 depending on how it was configured from the factory, tied to the instrument cluster and the ECU. If the CR2032 in the remote side dies, the remote buttons go dead but the transponder still starts the car since it is passive. Swap the CR2032 first before assuming it is an immobilizer fault.

2010 Audi S4 Remote Flip Key Replacement - Fast, Affordable & Professional

Out in the Santa Susana area of Simi Valley, early morning, a woman was at a rental car return lot trying to switch back to her own 2010 Audi S4. One problem. Her only Audi key was not in her bag. She had left it at a hotel she checked out of an hour before. The hotel searched and found nothing. The key was gone.

She had a flight in six hours and an S4 she could not start.

She called the Audi dealer. Earliest appointment was the following week. Then she called me.

I got there in about 35 minutes. Her S4 uses the 4F0 837 220 flip key with a Megamos 48 CAN transponder and an HU66 blade. I connected my Smart Pro to the OBD port, pulled the immobilizer PIN from the ECU, and ran through the IMMO3 procedure to program a fresh key matched to her car's security. Cut the HU66 blade on my Condor, programmed the remote with FCC ID IYZ3314, and tested every function. Lock, unlock, trunk release, engine start.

She returned the rental, started her own car, and drove to the airport with time to spare. The dealer would have meant a week-long wait, rental extension fees, and a missed flight. She got a working key in under an hour, right there in the lot.

Audi S4 Mobile Service FAQ

Real costs, no dealer surprises

How long does it take to replace a key for a 2010 Audi S4?
If you still have one working key, adding a spare takes about 15 to 20 minutes of programming time once I am connected to the OBD port. The instrument cluster already knows a valid key exists, so the process is shorter. If every key is lost, the job runs closer to 30 to 45 minutes because I have to extract the immobilizer data from the ECU and generate a new key from scratch through the IMMO3 or IMMO4 procedure. Either way, the full visit from my arrival to you holding a tested, working flip key is typically under an hour.
How fast can you get to my location in Simi Valley?
Can I actually get a 2010 Audi S4 key made the same day I call?
