Keyboard key "g" stuck

Hello everyone,

I've just noticed my "g" key is stuck along the lower edge. If I press on purpose on that location, there is no motion. Right along the edge, and "a little bit" to the center of the key.

It may be just a problem of cleaning underneath the key. But, I have not easy access to a Genius Bar. There is a premium reseller where I live.

My computer is a MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports).

I will buy a can of compressed air, and try that first. If that doesn't work. Do you think I could clean it by myself? After watching a few videos, even though none of them showed the same keyboard I have, I get a pretty good idea on how to do it.

Thanks!

Carlos
