Which ones exactly?? That's really vital info to provide.

If by chance you are talking about 789uiojkl, it's because you have Mouse Keys turned on in Accessibility preferences.

Please reset the SMC 2-3 times back to back with no external peripherals connected to the computer. The link below shows how to do the reset.
