So I downloaded this pack:

Unfortunately, there is an issue.

The Noose, SUV, and CVPI models do not have collisions on their doors. I am not exactly someone who can use a model with a problem like that... so how can I fix it? If that's even possible?

I downloaded zModeller2. I activated the free trial. But obviously, the model is locked. 

 

I posted a comment on it, and the creator of the pack said they don't have the files any more, so they can't help me (but that was for a different issue I believe).

What can I do, if anything?

Sadly no, Collisions are model or 'coded' into the model itself, and if it is locked only the person that locked the file can add it. (if the still have them that is). I hope this answers your question

I know it's not the "done thing", but since the guy who made it doesn't have the files any more... could I unlock the model somehow?

I'm not to sure about that.
