Enter BIOS and see if those keys work by typing a BIOS password, not setting it though

Then I believe it is a hardware error :(

Do you have a warranty?

To confirm a hardware problem, plug in a USB keyboard. If it works the laptop probably needs a new keyboard

the external keyboard works well

probably some crud has got in between the key cap and the keyboard, can you carefully pry out the key cap or blow out the affected area with compressed air?
