WHY DO MY KEYS SEEM TO RESIST AND DRAG
There could be many reasons - Dust, crumbs, hair, or other particles can accumulate under the keycaps over time.
If anything sticky like coffee, or even sweat has gotten into the keyboard, it can leave behind a gummy residue that increases resistance.
On mechanical keyboards, the switches (the parts under each key) can wear out, leading to uneven resistance or a "draggy" feel due to friction in the stem or spring.
I hope this helps!
