You can also pop off the keys of most laptops if it's only certain keys sticking. Pop them off and get a qtip with alcohol, scrub it clean around the key and where the key strikes the bottom when depressed, then pop the key back on.
Most keyboards I've seen now-a-days are all in one unit though so removing the entire keyboard wouldn't do much good unless you are replacing it with a new one.

Sticking with my Pixel 3a, but had it unlocked from Sprint/T-Mobile.
