2013 Audi S4 Smart key Replacement - Fast, Affordable & Professional

Yes, I can make a key for your 2013 Audi S4 with no original. No spare needed. No existing key needed. I build one from scratch at your car. This is called an all-keys-lost job, and it is one of the most common calls I get because a lot of Audi owners bought their car used with one key and never got a second.

A mountain biker at a state park lot in Bridle Path neighborhood in Simi Valley lost his only key somewhere on the trail. He checked his jersey pockets, his pack, the parking area. Nothing. His S4 was sitting in the lot and he had no way to open it or start it. He figured the car was stuck there until a tow could bring it to the dealer.

I got to the park lot and started with my HU66 Lishi. The HU66 Lishi picks and decodes the Audi door lock by reading each wafer position inside the cylinder. It gives me exact cut depths for a new blade without the original key. Once I had the mechanical cut, I moved to programming. I connected through OBD, read the immobilizer PIN, and ran the all-keys-lost sequence which clears previous keys and registers the new one as primary. His smart key, FCC ID , was cut, programmed, and tested right there.

His car started in the same dirt lot. Total was 95. The dealer wanted 200 plus a tow. All-keys-lost sounds like a disaster, but with the right tools it is a routine mobile job on most older and mid-generation Audis.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”

2013 Audi S4 Pricing Questions

What it costs and what you get

Why is Audi key replacement so expensive?
Modern Audi keys are not just pieces of metal. A smart key has an encrypted transponder chip that communicates with your vehicle's BCM2 immobilizer module, plus remote functions that all need to be coded to your specific VIN. Newer Audi models from 2018 and up require online ODIS sessions tied to Audi's backend servers, plus GEKO authorization for security functions. That is why an Audi dealer can quote $600 to $1,400 for a single key. An e-tron owner saw a clean $1,012 invoice broken into three line items. The technology is real, but the dealer markup on top of it does not have to be.
