🔧 PRO TIP
The 2011 S4 is a B8 platform running the Megamos 48 transponder (CAN variant) inside an HU66-cut flip key, not a proximity smart key. The immobilizer is handled by the instrument cluster on these, not a separate BCM2 like later MLB cars. If your flip key blade looks chewed up or the key wobbles in the ignition, the HU66 wafer pack is wearing out and the blade is next. Get a copy cut from the lock decode, not from the worn blade, or you are just copying the damage forward.

2011 Audi S4 Smart Key Replacement - Fast, Affordable & Professional

Out in the Madera Hills neighborhood in Simi Valley, a rideshare driver flagged me down from a highway shoulder call. His 2011 Audi S4 had the key blade snapped clean off inside the driver door lock. The HU66 blade broke right at the shoulder. He had been running a worn copy for years and the tip finally gave out against a sticky wafer pack.

Another locksmith he called told him the cylinder would need to be drilled. New lock, new key, big bill.

I started with the flip key head still in his hand. The Megamos 48 CAN chip inside was fine, so I read the transponder data with my VVDI2 to save it. Then I slid my HU66 Lishi into the door lock. The Lishi fits the VAG keyway and can work around a stuck fragment without scratching the wafer surfaces. The broken piece came out in one pull.

With the fragment out, I decoded each wafer position for exact cut depths. No guessing from a worn blade, no copying old damage. I cut a fresh HU66 blade, rebuilt it into a new three-button flip shell with the original Megamos chip, and tested every function: ignition start, remote lock, remote unlock, trunk release.

He sat on the guardrail the whole time watching, like he was waiting for me to pull out a drill. I never did. The lock stayed factory, the car looked the same as when I got there, and he drove off for way less than that other quote.

“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

What does a 2011 Audi S4 key replacement include with EZ Car Keyz?
Everything. The flip key shell, the HU66 blade cut to your car's lock code, the Megamos 48 CAN transponder chip programmed to your immobilizer, and the remote buttons synced. I test ignition start, lock, unlock, and trunk before I leave. One price covers all of that plus the mobile trip to you. The dealer splits this into parts, labor, and a separate programming fee that together run dramatically higher. With us it is one number on the phone and that is what you pay.
Is a locksmith actually cheaper than the Audi dealer for a replacement key?
Does the 2011 S4 use a smart key or a regular flip key?
My 2011 S4 key turns but the car cranks and will not start. Is that the immobilizer?
Can I buy a blank Audi flip key online and have it programmed later?
