I have a few sticky keys on a Dell Inspiron laptop. As I am typing this note I am having no issues but then occasionally the n and b stick, as well as the space bar.
My laptop is a 2020 Dell Inspiron.

The keys are a low profile. I watched a video online where you sort of pick the edge of the key off and then clean with rubbing alcohol. That helped but the problem seems to come back.
I called Dell and of course it's out of warranty and they say I may have to replace the whole keyboard and by the time I ship it there and back it's $175.
What are my options? If you ever popped a key off there is another tiny white piece underneath that's delicate. I was nervous about trying to take that off for fear I'd snap it and be without a letter. :)
I have never spilled any liquid on the keyboard and generally keep it clean.
