Well this sucks that you can't use the old system of password unlockers for Dell.

I have 3 of these Lattitude 5420 systems that I'm asking for help with. I will start with one for now and test it out first.

Early thanks to whom helps out!!!

Out of curiosity. If one unit has been wiped of the admin pw with the fixed BIOS file, can I use the same BIOS file from the first one on the other 2 since I have to re-enter the service tag anyway?

upload here all you wanted to be unlocked. this unlocked bios cannot be used in other laptop.

Thanks Rex!! Worked like a charm.

Ok it took me a bit to grab the other BIOS images since one was an XMC chip. Now that I figured that out after searching, here they are.

How many have you got,don`t you want to learn how to unlock them yourself, a hex editor is all you need.

I'm hoping it's the last. But you are right, the laziness got the better of me. I just compared the previous fixed files and the original lock file with hex comparator. Is it really that easy? I was worried Dell went all Lenovo on us.

I'll try it myself and see.

[OntarioTL]

Ok, got it to work on the first try. Not as easy as I said. Simple to compare when you have a fixed and original BIOS. Hard to find the same string when address locations are off a little per BIOS image.
