Will removing the battery reset the EFI firmware lock on a Macbook Air 2012 model?

I doubt it. I'm looking on eBay, and amazon where you can send in your Mac and they will reset it for you. There has to be a way if they are doing it.
Not only won't it work, I believe that Apple classify the Air as a model that the user should not attempt to remove the battery. Out of curiosity, why do you want to?
I'm just concerned that's all!. Is there a reason that removing power to the EFI chip won't reset it like it does on all other models?
The way I understand it is that the EFI chip acts like the old EPROM modules, each EFI update re-programmes the chip, and that code remains power or no power....I think that's how it works....
Alright good thing then. Why am I seeing this on eBay and other sites though? They will take it and reset it for you.
This brings me back to say, my sister went to an apple store to get her aunt's reset because she had passed away and they wouldn't reset it without the paperwork you get when you buy it.
I'm also now looking for a way to crack these and find the algorithm that has many baffled. I would assume to see this figured out within months.
I not suggesting anybody try this, but in the old old day's we used to use EPROM burners....Times have changed and that would mean removing the chip, knowing the code etc. I used to play around with custom EPROM's, but my MBA isn't coming apart...
I love how ignorant people like you are. I'm simply a person who seeks knowledge. If you have no way or advice for me, then don't respond at all. I've already figured it out anyway.
Don't be so rude to people.
For the record, only Apple can reset the password. Those services on eBay will just have internal connections.
For the record, stating a fact that someone is ignorant isn't rude. Assuming like he did is, in fact, rude.

It certainly appears that way, since the OP's questions started with an expressed concern that their "employees" may find a way to reset it, then shifted to the OP wanting to figure out how to do exactly the same thing:
While the OP's motives may, indeed, be legit, the direction of this thread suggests a possible alternate interpretation.
