Anyone have luck with this on a 2015 Volkswagen Passat Syncro?

Hoping someone can confirm this works for a newer Volkswagen Passat Syncro.

Common questions about key programming, fob issues, and replacement options

Key Programming
Some vehicles allow DIY key programming using specific sequences (like turning ignition on/off with original keys). However, most modern cars require specialized equipment only locksmiths or dealers have. Check your owner's manual for your specific model.
