Make a couple of trials (i think 3) so that you can get a password **key**. Take this code and:

 - Go to https://bios-pw.org/
 - Key in the key code that you have in the *input field* and click on **Get password** button
 - A list of generated passwords will be displayed depending on the model of your computer.
 - So select your matching password and set it to unlock *BIOS*.   


**PS**: *Save it somewhere for further usage, otherwise, retry the above steps in case you got to unlock BIOS again.*
