How old is the laptop? Keypads do wear out. When mine went south once, it was first evidenced by a “drifting” cursor on the monitor screen, even though my mouse was perfectly still and I wasn’t operating the joystick or touchpad. Later, as my keypad worsened (and I still didn’t understand what was wrong) my center keys stopped working: in particular, I, J and K started to fail frequently.
At that point I called IT support (it was a work machine), and a half-hour later I had a new and perfectly functioning keypad (the surface under the keys that the keys operate) installed.
Your issue may very well be a foreign object under the key. I’d try @LuckyGuy‘s recommendation as the fix that is least intrusive and least likely to cause damage. Removing keys can be a problem; I’ve seen the attachment parts break as that was attempted.
