Tips for Audi A6 C5 Key Matching Process
1. The key matching requires a Megamos ID 48 key [the Xhorse super chip cannot be matched successfully], and the generated IMMO instrument data must be written back, and matching learning is required.
2. After reading the data, remember the PIN code, because the PIN code will be needed in the subsequent matching process. The learning process requires a clear ignition signal, and the matching will not be successful if the operation is wrong. The matching process must follow the prompts, such as waiting for 5 seconds and waiting for 2 seconds.
