Keyboard Bug?

Hello, today I was playing a game (Which unfortunately happened to be ranked) and when I loaded in my keys for my abilities would not work, this includes my backing, opening the shop and summoner spells. This has happened to me before but after reconnecting it just went back to normal, but this time it didn't and I tried reconnecting 3 times, but to no avail. Ending up losing the ranked game, so just to test it out I went into a custom with my friend and the keys still wouldn't work. I checked my keyboard, and even tried messing with the settings, but nothing worked. Is there some fix to this?
