Switch 2 prod keys and firmware are compatible when the keys come from the same system update as the firmware or a later one. The current recommended pair is prod keys 22.5.0 with firmware 22.5.0 on Lichii build 117.
What are the three compatibility rules?
- Keys ≥ firmware. prod.keys must contain the master key of the firmware’s key generation.
- Firmware ≥ game. The firmware must be at least the system version the game requires.
- Keys ≥ game. The keys must contain the master key the game was built with.

What happens when keys and firmware do not match?
When keys are older than firmware, the firmware install finishes but Lichii cannot decrypt its system titles, so games crash or the installed version stays blank. When firmware is older than a game, the game refuses to start and asks for a system update.
