Can you unlock a locked BIOS?

On the computer motherboard, locate the BIOS clear or password jumper or DIP switch and change its position. This jumper is often labeled CLEAR, CLEAR CMOS, JCMOS1, CLR, CLRPWD, PASSWD, PASSWORD, PSWD or PWD. To clear, remove the jumper from the two pins currently covered, and place it over the two remaining jumpers.

What does it mean when a BIOS is locked?

If it’s BIOS-locked, that means there is a password set on the BIOS that will appear on startup. Without it, you will not be able to use the computer.
