Compactlogix 1769-L35E locked

Hello! I'm working on a project. I cannot get online with the PLC. The compagnie who made the program does not exist anymore so they cannot help me. Does anyone knows how to unlock a locked controller ? Do you know a compagnie who can solve this kind of problem ? Otherwise my only option is to wipe the all thing and reprogram it .... which would be bad. Thanks !

There is no way to get around it and discussions about circumventing passwords are not allowed here. While the company may be out of business, you may find an old employee. Try LinkedIn.

I have heard that your local RA office may help you if you can jump through a lot of hoops to prove that you own the machine and are authorised to access the code. That's where I'd be starting.
