PT82

So my boot doesn't open. First it wouldn't lock on the Toad alarm and then after a while stopped opening. I took it to an auto electrician who has chased the fault back to the body module. When he pulled the required wire entering the module and probed it the boot opened.
This is where I am now. He has called two companies who said they can look at it but didn't seem confident. We've even emailed a company in America. Apparently whatever the fault is when it's fixed it will need to be coded to the car?

Does anybody know a company I could call who could help me. It's a Mitsubishi electrics module. Oh and the car is an imported hatch STI.
