🔧 PRO TIP
The 2000 A4 is B5 generation, and its immobilizer is the Megamos 48 (ID48) crypto transponder system, not the newer BCM2 found on MLB cars. The key is a 4-button remote flip, FCC ID MYT8Z0837231, part number 4D0837231P. A dying CR2032 kills the remote buttons but won't affect starting since the transponder chip is passive. If your remote range drops or buttons go intermittent, swap the CR2032 first. The immobilizer side is separate.

2000 Audi A4 Remote Flip Key Replacement - Fast, Affordable & Professional

Got a call from a guy out near Refugio State Beach in Santa Barbara. His 2000 Audi A4 flip key had been acting flaky for weeks. Lock button worked from two feet away, unlock did nothing unless he pressed it against the door. He figured the whole key was dying.

I pulled into the lot and he had the key sitting on the hood like it was evidence. Popped the flip housing open right there. The CR2032 was corroded on one contact, and the rubber button pad had a hairline crack running across the unlock side. Classic on these 4D0837231P shells. The B5 A4 flip key housing is over two decades old at this point, and the plastic gets brittle.

Swapped in a fresh CR2032, transferred his cut blade and the ID48 transponder chip into a new aftermarket shell, and tested every button. Lock, unlock, trunk, panic. Range checked from about 30 feet out. Then I confirmed the immobilizer side by starting it three times cold. The Megamos 48 chip read clean each time, no dash flicker, no hesitation.

He kept saying he thought the whole key needed reprogramming. It didn't. The transponder was fine. The remote frequency was fine. It was a worn-out shell and a corroded battery contact. He paid a fraction of what the dealer quoted him over the phone and drove off in about fifteen minutes.

“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”

Audi A4 Mobile Service FAQ

Real costs, no dealer surprises

I lost all my keys for my 2000 Audi A4. Can you still make a new one?
Yes. All-keys-lost on the B5 A4 means pulling the immobilizer data from the instrument cluster, specifically the VDO or Bosch cluster module that stores the Megamos ID48 crypto key data. I read the SKC (secret key code) from the cluster, generate a new ID48 transponder matched to that data, cut the blade to the HU66 profile, and program it at the car. All previous keys get wiped out of the system. Dealers will want the car towed in, the VIN verified through Audi HQ, and a wait for parts. I do it on site, same day.
Do I need to tow my 2000 A4 to the dealer if I have no working key?
How long does an all-keys-lost replacement take on my 2000 Audi A4?
My 2000 A4 key turns but the engine cranks and won't start. Is it the immobilizer?
Can I buy a blank flip key online and program my 2000 A4 myself?
