Out of curiosity, I just opened my two never-used backup infokeys, and one has developed the same problem as yours. They've been stored in a downstairs hutch in normal temperature and humidity. I've seen this happen to LCDs before, but don't know what causes it. Maybe leakage of the liquid? It will likely get worse. Since they're long out of warranty, I doubt there's anything we can do about it. At least they should still work. I'll contact my dealer to see what he's heard.
