1999 Audi S4 Remote Flip Key Replacement - Fast, Affordable & Professional

Lock decoding means I read your car's lock to create a key without drilling, without breaking anything, and without replacing the lock cylinder. The car looks exactly the same when I leave.

A rideshare driver on the highway shoulder in Escondido had his key snap inside the door lock of his 1999 Audi S4. The HU66 blade broke clean off. He had been using a worn copy for years and the tip finally gave out when the wafer pack inside the lock was sticky from age. Another locksmith he called told him the lock would need to be drilled out. New cylinder, new key, big bill.

I used my VVDI2 to read the transponder data from the broken flip key head since the chip was still intact. Then I used my HU66 Lishi to extract the broken blade fragment from the door lock. The HU66 Lishi fits the VAG keyway and can work around a stuck fragment to slide it out without scratching the wafer surfaces inside. Once extracted, I decoded the lock by reading each wafer position for exact cut depths. His flip key, FCC ID MYT8Z0837231, was a 4-button unit that I rebuilt into a fresh shell with the salvaged Megamos chip.

No drilling. No cylinder replacement. His total was $271. The other locksmith wanted $502 or more with a new lock. Destructive entry should always be the last resort.

“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”

Audi S4 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.
