Problems resetting BIOS password. Dell Latitude e6420

[Ethanh100]

Hi,
I have a dell latitude e6420 that I got from a friend of mine who has been using it for a while and he gave it to me. I installed a fresh install of windows 10, and noticed that the BIOS on the laptop was locked with a password. I needed to change the boot priority order so I didnt have to spam f12 every time i booted up to select the proper partition. I knew that this could be resolved by a CMOS reset so I unplugged the bios battery for a minute or two and plugged it back in, however the password was still there. I researched into this and found the bios key generators and decided to try it. The bios was giving me the system number shown in the picture below, so I plugged it into https://bios-pw.org/ and it gave me 4 or 5 codes, all which did not work. Can someone help me unlock this? Thanks
