Lazy blink or quick blink?
If a "lazy blinking" key won't work, I have no solution (and if someone figures out one, I also want to know).
But if "quick blinking" key won't work, try removing board from key case, desoldering coin cell battery holder from board, reflowing board solder joints (some previously covered by the battery holder), reinstalling the battery holder and battery, and reassembling. Apparently the solder connection gets unreliable. If you need to press the key really hard or have intermittent function (unreliable operation), this could also indicate the board solder joints need reflowing.
