Kad uljucis komp dode ti takav error message "keyboard is locked out - unlock key" onda ljepo:
It locks access to the keyboard for security reasons, such as in a business environment where someone else might be able to access the computer when the user is away.
You might have to check inside the case, the keylock should have 2 wires running to a jumper on the motherboard. If it is disconnected, reconnect it. Some systems use a 5 pin plug that holds the wires for the power on LED as well.
Also see if you can find a jumper, computer shops should have plenty lying around. Try it with a jumper on, and with a jumper off, one of the two should allow access to the keyboard. Often the proper jumper is marked, sometimes it's not, so you might need a motherboard manual to identify it.
