As the title states, those keys are ot workimg. Sorry but im really strugglig to type so usimg altermative keys imstead. Tried all steps here https://mysupport.razer.com/app/answers/detail/a_id/9742 to o avail. Had the keyboard for about three years so mo warrramty either. Amy ideas will be very welkome. They just stopped workimg ramdomly last might. Mo physical damage that i recall. 

Had similar issue straight after i bought it, but them i still had a warraty so pretty ammoyed atm

Ok founda different keybaord. One thing i didnt manage to do would be “The best way to reset a Razer keyboard is by going to Razer Synapse 3.0's settings and click "Reset" from the side options” that i found in this thread https://insider.razer.com/razer-support-45/how-can-i-make-my-keyboard-factory-reset-25843
