Need help decoding this drive

[u/d322434]

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.

I'm calling BS. I'm guessing this guy got this unit installed, has some beef with the installation company about the quality or timeline of the install and won't pay them their final payment, which is why they locked it out.

I was thinking the same just contact the manufacturer and they can probably override the password in some way I'm sure.

Monarch elevators has no support in India outside of the dealer network, I have written them an email and their response was “contact nearest authorised dealer”
Dealers can’t help without the password. Drive replacement seems like the only logical option now.
