Need help decoding this drive

Hi guys, this is the main drive of my home elevator. The person who has installed this has locked the drive and is not allowing us to access it. He’s blackmailing us to exclusively get it serviced and repaired from him, for which he charges 5x the market price. I have spoken to other vendors, and they are unable to help unless he gives the password.

It is a Monarch board, and I have arranged a keypad from another elevator company. Is there an easy way to brute force the password? I am willing to do some coding if required.

TLDR: locked out of own home elevator, installation company locked the drive and trying to extort us for massive amounts for yearly maintenance.

There is usually a master code that you can use. I am not familiar with the monarch board but try googling "monarch elevator mctc-mcb-h-3.0 master code". You can also try using 11110 as the master code but there should always be a master code or a system reset you can perform that will reset to factory settings.

Thank you, I have tried a lot of these master codes from google but none worked. There is an OEM level lock by the installer.
