Yes you could possible void your cars warranty. My Toyota dealer programmed my windows and panoramic roof to open and close via remote free of charge it took them less than 10 minutes

Probably because seat belt alarms on every seat became mandatory in the EU from September 2019, whereas previously (from 2009) only the drivers seat had to have a seat belt alarm.

I don't see any reason they could affect the warranty.  The warranty is for replacing things which wear out/break/stop working prematurely.
