🔧 PRO TIP
On 2013 and newer Audi MLB models like the A4, A5, Q5, A6, and Q7, the immobilizer module called the BCM2 is encrypted. That's why some locksmiths say "dealer only" on these cars. We carry the bench equipment to read that module directly.

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.

“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.”

Common Audi S4 Pricing Questions

Common pricing questions answered

What is the cheapest way to replace my Audi key?
Call a mobile locksmith before you call the dealer. Audi owners who go straight to the dealer pay $600 to $1,400 or more for a single key replacement. A 2022 A5 owner was quoted $1,400 at the dealer while a specialty locksmith in the Bay Area handled similar work for about $300. On older models like a 2009 TT, one owner bought an OEM style fob online and paid a locksmith $100 to program it. With EZ Car Keyz, a smart key for the 2015 Audi S4 is around 95, and that includes everything. No towing, no ordering keys from Germany, no multi-week wait.
