Problem:

Added keyless entry to an 2023 Audi A3 8Y MQB49 5D system usingKeydiy KD-X4and now the keyless entry no longer works (locking and starting work). When I pull the handle, the LED on the key flashes, but the car doesn’t unlock. Any solution?

Solution:

Audi A3 5D uses a UWB key that’s why proximity in handles doesn’t work; youmust use original uwb key.
1 uwb key + 1 non-uwb key = no UWB function.

Keydiy FGB08comes with the 5Dbasicprogram. It does not currently support vehicles with UWB functionality.
It only supports the 5D program for all vehicle models.

Customer solution:
It happened to us on VW Polo 5C key , than we added the KD key first and the original key as second and it helped, the Keyless entry and start was working as it should.
It is worth a try.
