I was able to solve passworded and pinlocked MacBook model A1286 (late 2011) so I am able to remove pinlock and EFI password for good. All serials and user data remain untouched. Method is fully safe for hardware and software of laptop
Anyway if someone wants help with password or pinlock in Poland or Europe, simply email or PM me.

Unlock is possible if you send laptop , I need access to mainboard. You can expect unlock price around 50EUR.
Unfortunate there are not any remote solution, guess why ? because your system is locked, so not system activity, so not working with net, so not remote solution.
Or try at Apple Store, maybe they can help you.

Problem: Your Mac got locked via iCloud and on boot displays "Enter your system lock PIN code to unlock this Mac." It also sets an unknown password on the firmware so you can't boot from a disc. And you don't know the PIN code for a variety of reasons (not my business).
Thumb resize.

Solution: Mount the locked drive on another machine, find the PIN, re-install the locked drive into the original Mac, enter the PIN, resume your business.

Tutorial:
*I'm going to post the steps I did in my case and suggest steps you might take if your case varies.

Things Needed:
1. Alternate machine with space to mount an additional drive. (works on Mac or PC*)
*If you're using a PC, you'll need to download and install Mac Drive to be able to read the contents from a Windows environment.
2. You might need a SATA to USB adapter if you have a laptop without room for an additional drive.
3. Screw driver to disassemble the Mac.

Step 1: Remove the locked hard drive from your Mac.
You can find detailed guides for your specific machine at Mac Repair - iFixit

Step 2: Install the drive into your alternate machine. But make sure you do *not* boot from it. Boot from your regular drive.
If you do not have an alternate machine, feel free to ask a tech buddy of yours to lend you their machine.

Step 3: Once booted into the alternate system, locate your locked drive.
In my case it was drive D: on Windows. Now browse to \Users\username\Library\Application Support\iCloud
Thumb resize.

Step 4: In the folder "iCloud" find a file named with a bunch of numbers: ##########.lock In my case it was: 1138515150.lock
Thumb resize.

Step 5: I'd suggest that you take a picture of this file name for accurate reference. But you can also just write it down.

Step 6: Once you got the number, power down the machine and remove the locked drive.

Step 7: Install the locked drive back into the original locked Mac.
Follow your iFixit guide from Step 1 in reverse to put the drive back.
*It is important that you put it back in the machine where it was originally locked* so that the motherboard firmware will be unlocked in the next step.

Step 8: Boot up the locked Mac and referencing the number you recorded, you can start trying 4 numbers at a time for the PIN.
Try the first 4, then the second 4, and so on..
For example: 1138, 1385, 3851, 8515, 5151, 1515, 5150.
In my case the PIN was the second to last 4 digits: 1515
If you typed in more than 10 combinations, then it says that you are locked out for a minute. Just restart the machine and continue entering the combinations from where you left off.

Once you enter the right PIN, the Mac will instantly reboot proceeding to where you were at when the lockout occurred. It will also remove the firmware password.

Enjoy your unlocked Mac!!
And please let us know if this method worked for you. Thanks

method not working on 2011 models

Good solution for this is using t e n s y 3.0 board. This board can be easy programed and you can use it as keyboard to give codes for you.

The macbook chip is a high speed eprom . Spi package need a programmer capable of reading writing and erasing. I just need good bins I have everything else . Its really easy guys. The other method with those other self ccontained programmers don't write a new bin but it serosnout the areas o n bios chip thatbthe lock is on.
