the keys j and u on my MacBook don’t work anymore is there anyway to fix this

No much you can do with these newer Macs but there are a couple of long shots to try at home:

— Do an SMC reset. Instructions here: Reset the SMC of your Mac - Apple Support

You have not shared the model of your Macbook Pro with us, so note in the article that the reset steps vary with model. If the SMC reset fixes it, call it done.

— Check the battery for swelling. Diagnose looking for these classic symptoms:

• • Unexpected trackpad and/or keyboard behavior.
  • The gap between the display and the deck is not even when the display is closed.
  • The gap between the bottom plate and chassis is uneven in places.
  • Some of the screws that hold the bottom plate have popped out.
  • The trackpad surface is higher than the surrounding deck surface.
  • The computer "rocks" a bit on a known flat† surface.

† — I find solid-surface and "granite" countertops very effective flat test surfaces.

The battery is NOT a user-serviceable part in Macbook Pros made in 2012-2013 and later. A swollen battery must be dealt with immediately because the swelling exerts enough force to bend metal and potentially rendering your computer irreparable

Plug in an external keyboard as a work around to get you going again...

until you settle on a resolve for your issue

Setup an appointment at an Apple Store and have it looked at. It may require a keyboard replacement.
