🔧 PRO TIP
Around 2013, Audi encrypted the BCM2 module on A4s. That means all-keys-lost on a 2013-2016 A4 requires physically removing the BCM2 from the trunk area, reading it on a bench, and then programming your new keys. It's a 2-4 hour job, but it beats a tow plus dealer markup.

2012 Audi A4 Smart Key Replacement - Fast, Affordable & Professional

She was at the outdoor mall in Spring Valley pushing her infant in a stroller when her bag was snatched off the stroller handle. Car keys, wallet, phone. She borrowed a phone from a store employee and called her husband first, then the police, then me.

Her 2012 Audi A4 was in the garage and she had zero keys. The Audi dealer told her husband they could order a key but it would take 3 to 5 business days and the car would need to be towed. They recommended a full immobilizer reset since the stolen key could still open and start the car. Combined estimate was over $700.

I got there that evening. All-keys-lost is different from adding a spare. When you add a key, the car already trusts an existing key and just registers a new one. AKL means I clear the entire key memory so the stolen key can no longer start the engine. I used my IM608 to access the immobilizer module, wipe the old key data, and program two new smart keys from scratch. Her fob, FCC ID IYZFBSB802, was a 4-button proximity key. I decoded the lock, cut the emergency blade, and had both fobs working before the police finished taking her statement.

She drove home that night with her baby. Total was $326 for two new keys. The dealer estimated $597 plus a tow and a week-long wait. The stolen key is dead to the car.

“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”

Audi A4 Mobile Service FAQ

Real costs, no dealer surprises

My key broke in the ignition. Can you get it out?
Yes. On older Audi models with a traditional ignition cylinder like the B7 and B8 A4 or 8P A3, broken key extraction is a common call. One 2009 A4 owner had the key jam in the ignition and the car would not start. A 2007 A3 owner had the same issue and ended up needing the lock mechanism pulled and a pin replaced. We can extract the broken piece without damaging the cylinder in most cases, then cut a new blade from the original code and program a replacement. On push-button Audi models, the emergency blade can snap in the door lock if forced, and we handle that extraction the same way.
