Want to tell whether your Audi key is 5C or 5D? Follow these steps based on the key shell design.
Step 1: Gently remove the key shell.
Step 2: Examine the interior surface of the shell.
Step 3: Count the lines of symbols:
5C Key → Has 3 lines of symbols.
5D Key → Has 4 lines of symbols (encrypted type).
Important reminders:
Duplicating a 5D key requires the original key.
If your 5D key includes UWB, a high-version original key is needed for copying.
This guide is only suitable for Audi 5C/5D vehicles. It may not apply to VW 5C/5D vehicles.
For precise identification, use an OBD tool like Keydiy KD-X4 5-in-1 key programmer to check the key chip type and key status directly.
