To obtain an exclusive unlock code Siglos Karaoke Professional , you must purchase a license directly from the official Power Karaoke

Ensure you didn't copy a space at the beginning or end of the code.

Some online shops selling karaoke music tracks (e.g., KaraokeVersion, Sunfly) occasionally bundle a Siglos unlock code with a purchase of 50+ songs. Again, this is a paid, hardware-specific code.
