New 2013 Audi S4 key fob when all keys lost from EZ Car Keyz Simi Valley CA
🔧 PRO TIP
The 2013 Audi S4 is a B8.5 generation car, which means it sits in a sweet spot for mobile key work. The immobilizer system on these reads the transponder during the start sequence, and the door lock cylinder is still a full mechanical cylinder you can pick and decode. That matters because on an all-keys-lost job, decoding the lock gives you the cut without needing a key code printout from the dealer. The VAG-compatible diagnostic tools that cover the broader VW Group ecosystem work well on this generation, which is part of why parts and programming support are solid compared to later models that moved to more locked-down online authorization. If you're just dealing with a fob that stopped triggering the doors but the car still starts, check the fob battery before assuming the worst. A dead battery in the fob kills remote functions but the car may still start if you hold the fob close to the start button area.

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

I got a call from a guy over in the Royal/Kadota area of Simi Valley. He'd been out on the trails, mountain bike still strapped to the roof when he got back to the parking lot and started checking his pockets. No key. He went through the pack, the jersey, the hydration vest. Nothing. Just his S4 sitting there, locked, with the bike rack on top.

He'd already called the Audi dealer while he was still sweating from the ride. They told him he'd need a tow, a wait for parts, and at least a couple of days. He found me after that.

I pulled up and started at the door cylinder. Picked and decoded the lock to get the exact cut depths for a new blade, all done mechanically without touching any electronics. Once I had the cut, I moved to the OBD port, read the immobilizer data, and ran the all-keys-lost sequence. That process clears every previously registered key and enrolls the new one as the primary. Nothing from his old fob would open or start the car after that point, which is actually the security feature working correctly.

The new key turned over the S4 right there in the lot. Bike rack and all.

He'd been mentally preparing for a tow bill on top of whatever the dealer was going to charge. The mobile job was a fraction of that, done on site, and he drove home the same afternoon.

“My Chevy key snapped while I was running errands in North Oxnard. He removed the broken piece from the ignition, cut a new blade, programmed the transponder, and tested everything thoroughly. The whole job was smooth and professional. Best automotive locksmith I have used.”

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Audi S4 Mobile Service FAQ

Real costs, no dealer surprises

Why is Audi key replacement so expensive?
A few real reasons stack up on these cars. The key itself contains a programmed transponder that has to be enrolled into the immobilizer, and that enrollment requires the right diagnostic equipment and the ability to read or calculate the immobilizer PIN from your specific vehicle. That PIN is not printed anywhere you can easily find it. On newer Audi models, that process requires a live connection to the manufacturer's backend authorization system, which adds cost and time whether a dealer or an independent shop is doing it. The 2013 S4 is a B8.5 car, which means it predates those stricter online authorization requirements. A qualified locksmith with proper VAG-compatible tools can handle the work without the manufacturer's server session, which is one reason the job stays more reasonable on this generation than on something from 2018 forward. The dealer charges what they charge partly because of the technology and partly because of overhead. The technology is real. The markup on top of it is negotiable when you go elsewhere.
