I believe you can loosen or remove something beneath the car to take it out of park. But that’s not going to allow you to switch the car on to release the steering lock or anything else. You’re better off just moving the car by other means (see the suggestion above my post) until it’s sorted. It’s going to be the easier option.
The question really arises as to what surfaceand incline you want to move it on?
Mike's advice will get it to roll as easily as normal but is the harder option. Dollies work well on smooth surfaces but are a pain on anything else. They also have a tendency to move sideways which can be useful but is a risk when going on inclines.
Thanks for the help guys. We took apart the electrical actuator on another transmission we had and made a tool from it to disengage park. This got it off the transporter and we now have a key. Job sorted
