1998 Audi S4 Remote Flip Key Replacement - Fast, Affordable & Professional
Your 1998 Audi S4 uses a Remote Flip Key. On the smart key models, that means a fob housing with 4 buttons on the face, a CR2032 battery inside powering the wireless communication, and an emergency HU66 blade tucked inside for backup entry. The car detects this fob through proximity antennas in the doors and cabin. Without it, the engine will not start.
A graphic designer at her townhouse driveway in Fallbrook had a S4 with a cracked smart fob. The housing had split at the corner from being dropped on the garage floor and the emergency blade was rattling loose inside. The dealer told her the only option was a brand new fob, programmed from scratch. $512. What they did not mention was that the electronics inside her cracked fob were still working perfectly. The circuit board and antenna chip were fine. She just needed a new shell.
I used my ACDP to read the BCM2 immobilizer data as a backup before starting any work. The ACDP reads the encrypted security module data directly, which gives me a safety net in case anything unexpected happens during a shell swap or reprogram. I moved her working electronics into a fresh housing, replaced the weak CR2032 battery, and verified every button plus the comfort access and push-to-start. Her fob, FCC ID MYT8Z0837231, worked exactly like it did before the crack.
She paid $278 for the shell swap and battery. The dealer wanted $512 to replace the entire fob when only the plastic was broken.

“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.”
“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”
