How to fix difficult-to-press buttons on the keyboard?

Question

Keyboard

Hello, I have problems with my computer (laptop). After the active use of one key (Whether it's a double with a run in the game), it started to jam for me. No, it presses well, but it is very hard to press
When writing text, I have to press it for 2 minutes to finally print it
Almost the same problem with a wireless mouse, I press it and after 1 week of active use it misses some clicks
Change the mouse did not try what to do?

Perhaps the dirt got inside, or maybe the contacts in the buttons are bad.
Disassemble and check - it may be enough to clean the contacts with something, or you may have to change it.
