2010 Audi Q5 keyless sensor issue

[Gaellat]

I replaced the door handle on my 2010 Q5, but it still doesn't work. I tried changing the settings, but no luck. The trunk works fine, but the other doors won't unlock with the keyless sensor. What could be wrong?

It could be an issue with the keyless entry system, sensor malfunction, or wiring.
