2018 Audi A3 Replacement - Fast, Affordable & Professional
A vet tech who works at a grooming spot in Pleasant Valley Fields in Oxnard called me about her 2018 A3. Another locksmith had made her a key maybe ten days earlier. It worked fine the first week, then started acting up.
Mornings, the car would start no problem. By evening, push-to-start refused to detect the key. She thought the car had an antenna issue, maybe a failing kessy module or a wiring fault in the steering column.
I pulled the key apart on her dashboard and read the chip with my VVDI2. There it was. The previous tech had used a generic transponder that was close to Megamos AES spec but not a proper match. On the MQB IMMO5 system, a near-miss chip can pass initial registration just fine. The car accepts it, starts, drives. But Audi's immobilizer runs a deeper cryptographic verification over multiple drive cycles. After enough checks, the system flags the mismatch and locks the key out. It is a slow failure that looks like an electrical gremlin.
I programmed a new key with the correct Megamos AES chip matched to her A3's IMMO5 module. Also found her remote battery was low, which was making the intermittent detection worse on the comfort access side. Swapped that too.
She watched the whole thing from the parking lot. Took about 25 minutes. The old key went in her glovebox as a cautionary souvenir.
