2015 Audi S4 Smart key Replacement - Fast, Affordable & Professional
Push-to-start all-keys-lost on a BCM2 Audi is the job that scares owners the most. No key slot. No way to physically turn anything. The car needs to wirelessly detect a smart fob that is registered to its encrypted BCM2 module before it will even power up. If that fob is gone, the car feels bricked.
A conference attendee at a resort hotel valet in Simi Valley near Sinaloa Lake area on a Saturday night had a 2015 Audi S4 with push-to-start and zero keys. The valet had returned his car but he realized his fob was gone, probably left in a conference room that was now locked. The hotel concierge told him smart key replacement was dealer-only and the dealer was closed until Monday.
I drove to the resort. Push-to-start AKL on BCM2 Audis is more involved than a flip key job because the encrypted module needs to be accessed and its security data read before new keys can be generated. I used my ACDP to pull the BCM2 EEPROM data, sent it to the calculation server, got the return file, generated a dealer-level key, and then performed OBD key learning. His smart key, FCC ID , was a -button proximity fob.
His car started in a resort valet lane on a Saturday night. Total was 95. The dealer route would have been 200 plus a multi-day wait. Smart key AKL on Audi is not dealer-only. It is tool-dependent and process-dependent.

Five Stars From Rescued Audi Drivers
Reviews from customers we rescued
“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
“Super fast service. About 20 minutes from the call he was already there. He had an authentic replacement on hand and made a spare key for my 2017 Nissan Rogue in about 15 minutes. Great prices, friendly, and very professional.”
“I lost my key and called EZ Car Keyz. Marco was great. He arrived quickly, explained everything clearly, and kept me informed throughout the entire process. The service was fast, professional, and fairly priced.”
