Keys on laptop don't work

[Robotic]

I cleaned my laptop with some electronic cleaner on a paper towel and then later realized that my "y 6 /" stopped working. I popped the keys off and cleaned it. I didn't see any damage or stuff blocking the keys. Anyone know what else I can do. I might have to take it to My Mac Dealer and have them take a look at it.

The keyboard ribbon connector may have come loose for some reason. I discovered this happened on my laptop (perhaps due to heat) and I had to remove the keyboard and push the connector back in. It had come out only about 0.5mm but that caused some of my numpad keys to work intermittently.
