What do such engineers do to recover or reset the firmware password? I long ago forgot my MacBook Air's firmware password, but haven't needed it until now. I'm quite comfortable opening up my laptop, even if it voids my warranty, but cannot find any information on how the reset is performed.
With older models, one needed only to change the hardware configuration (e.g. amount of installed RAM) and then reset PRAM three times to force a reset of the firmware password. I presume this is not possible because the MacBook Air has no user-removable parts (since RAM is soldered to the motherboard, for example) but it is not clear what alternatives exist.
Apple probably require all those in the know to keep it to themselves, but no doubt some hacker has figured it out. I'd be grateful if they would share!

It's not the sort of thing a hacker can easily 'figure out' -- as I understand it, the procedure involves calling Apple's Service Provider Support, proving you're an authorized service provider, reading them a code from the computer and typing in the countercode they give you..
Mind you, that doesn't mean you're out of luck. If you have admin access, and a 10.6.x install DVD or USB key for your Mac, this MacEnterprise posting has instructions to use setregproptool to enable/disable the firmware password. If you have Lion, it's probably on the recovery partition somewhere, but I haven't investigated.
An AASP does by no means 'bypass' the Firmware Password, it is simply removed with a tool specific for that exact machine.A specific Key combination is used on the Firmware Password screen on the Mac that needs it removed, this presents a unique Hash code on the screen of the Mac.Generally this Hash code needs to be sent to Apple Technical Service Provider Support, they will send the AASP the unique 'file' that is used to remove the password from that specific machine.
There is no 'Home' solution yet for the removal of these kind of passwords on updated models, an AASP or a Apple Store can do it for you.

Let me save you a huge headache — don’t set an EFI password on your Mac unless you have the original receipt for that machine.
If you buy your Mac off Craigslist, like I did, and your daughter writes half a novel for her high school class but never backs it up elsewhere (note – always back up your stuff!), and then her MacBook Air suddenly won’t boot up, the EFI password the previous owner put on the laptop will prevent you or Apple from accessing the hard drive or ever using the computer again.
Hypothetically, of course.
If you don’t want to have to tell your daughter she loses her computer and will need to wait a week while you find a way to connect her SSD to another Mac and find her files, disable that EFI password now.
Here’s how.
What’s an EFI password? Also known as an open firmware password on older Macs, it’s a low-level password that prevents access to your Mac’s troubleshooting routines, like Recovery partitions or Target Disc modes. Essentially, it’s a way to lock your Mac down to keep thieves from accessing your data via one of these methods.
If you’ve set it and want to disable it, and you know the password, here’s what you can do.
Hold down your Mac’s power button until it shuts off. Then, holding down the Command and R keys on your keyboard, press the power button to power your Mac back up. You’ll get into the Recovery System this way. If you’ve previously set the EFI password, enter it here.
Next, you may need to select the language you want the Recovery Partition to use.
Click on the Utilities menu and choose Firmware Password Utility. Click the Turn Off Firmware Password button, and enter the password you used again. Finally, click Turn off Firmware Password again, and then restart your computer.
If you’re in a seriously high-risk industry and you’re concerned someone might want to grab your data using the Recovery partition or by booting from a separate hard drive, an EFI password is a sure way to make sure your computer is inaccessible, even to you should you forget the password.
For most people, it’s overkill. But if you do set one, do yourself (and your hypothetical daughter who ignores your pleas to back up her computer) a favor and write that password down in a ton of places so you never, ever forget it. That’s a horrible security practice, but I sure wish someone had done so when they set it on our MacBook Air.
