🔧 PRO TIP
The 2000 S4 runs the Megamos 48 (ID48) transponder system through Audi's immobilizer III (Immo3). The key is a remote flip style, FCC ID MYT8Z0837231, part number 4D0837231P, with an HU66 blade and CR2032 battery. If the remote buttons die but the car still starts, it is almost always the battery or corroded contacts inside the fob, not the transponder. The transponder is passive and does not need a battery at all. Swap the CR2032 first, clean the board contacts, and retest the remote range before assuming the worst.

2000 Audi S4 Remote Flip Key Replacement - Fast, Affordable & Professional

A woman staying at one of the smaller hotels along Main Street corridor in Ventura called me around 8 PM. She had one key for her 2000 Audi S4, tried to swap the CR2032 herself, bought the wrong size cell, and bent the battery leaf contacts forcing it in. Remote was dead. Car would not recognize the transponder either because the fob housing was not seated back together right, and the ID48 chip had shifted in its slot.

The dealer she called told her to tow the car in. Two business days minimum once it arrived. She was leaving Ventura in the morning.

I met her in the hotel lot. Opened the 4D0837231P fob on the hood so she could see inside. The contact leafs were bent inward and the ID48 glass transponder had slid sideways off its cradle on the circuit board. Straightened the contacts, reseated the chip, dropped in a correct CR2032, and snapped the housing shut.

Then I tested every button. Lock, unlock, trunk, panic. Walked the perimeter checking remote range. Had her start it twice, turn it off, pull the key, reinsert, start again. The immobilizer III handshake was clean each time, no dash warning, no flashing LED on the cluster.

She just watched the instrument cluster for a few seconds after the last start, like she was waiting for something to go wrong again.

The whole thing took about twenty minutes. A fraction of what the dealer wanted, and she kept her morning plans.

“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.”

Audi S4 Mobile Service FAQ

Real costs, no dealer surprises

I am locked out of my 2000 Audi S4 with no spare key. Can you come to me in Ventura?
Yes. I come to you wherever the car is along Main Street corridor in Ventura. I carry HU66 key blanks, ID48 transponder chips, 4D0837231P fob housings, and the programming tools for Audi's Immo3 system. No tow truck, no dealer trip. I cut the blade on site with my mobile key machine, program the transponder through the OBD port using the instrument cluster's login code, and hand you a working key. All-keys-lost on this generation typically takes 30 to 45 minutes depending on whether the cluster gives up its SKC cleanly or I need to pull it from the EEPROM.
Do I need to tow my 2000 S4 to the Audi dealer for a replacement key?
What do I need to prove I own the vehicle before you make a key?
My 2000 S4 starts fine but the remote buttons do nothing. Is the whole key bad?
Can I buy a 2000 S4 key fob online and program it myself at home?
