Discount 1998 Audi S4 transponder key from EZ Car Keyz Oxnard CA
🔧 PRO TIP
The 1998 S4 runs a Megamos 48 (ID48) transponder inside the flip key, and the immobilizer is the Bosch Immo2 system tied to the instrument cluster (part of what Audi calls the Immobilizer II generation). The FCC ID MYT8Z0837231 covers the 4-button remote, and the blade is HU66. If your remote buttons die but the car still starts, that is a separate RF module issue, not the transponder. The remote and the immobilizer chip are two independent systems living in the same shell. Swap the CR2032 first before assuming the worst.

1998 Audi S4 Remote Flip Key Replacement - Fast, Affordable & Professional

A guy down at Channel Islands Harbor in Oxnard had just bought a 1998 S4 from a friend of a friend. Clean car, fair deal, one key. The seller told him a spare would be cheap.

He called the Audi dealer. The number they gave him was not cheap. He had just put down money on the car, first month of insurance, registration. Another big hit for a single key was not in the plan.

He found me online and asked if the dealer quote was normal. I told him it was. Dealers charge what dealers charge. But I can do the same key, same cut, same programming for a fraction of what they wanted because I do not carry the overhead.

I met him in the gym parking lot before his workout. His S4 had the standard B5 platform flip key with the HU66 blade and a Megamos ID48 chip inside, immobilizer controlled through the Immo2 module in the cluster. I used my VVDI2 to read the existing key's transponder data and clone it onto a fresh ID48 blank. Whole process took about 25 minutes, most of that just the tool cycling through the crypto read.

He drove off with two working keys. That second key also means if he ever loses one, the next replacement is a simple add-a-key instead of an all-keys-lost situation, which saves a good chunk down the road.

Audi S4 Mobile Service FAQ

Real costs, no dealer surprises

Do I have to go to the Audi dealer to get a replacement key for my 1998 S4?
No. A mobile locksmith with the right VAG-platform tools can cut and program your flip key on site. A lot of S4 owners assume the dealer is the only path because general locksmiths often refuse Audi work. The Megamos ID48 chip and the Immo2 system need specific diagnostic equipment, which most shops do not carry. The dealer route means ordering the key blank by VIN (part number 4D0837231P), waiting days or sometimes weeks for it to ship, then scheduling a programming appointment on top of that. I carry the blanks and do the full job in one visit, same day.

My 1998 S4 cranks but will not start after a cluster swap. Is that the immobilizer?
