Is it possible to brick an FRM by testing it on another car?

A friend of mine has an '07 n54 that is supposedly having electrical issues like, doors not locking, E-brake light permanently on, windows not working ,Etc. He believes his FRM is fried and wants to see if swapping in my '09 n54 FRM will change anything to help confirm his is bad.

My question is, will I have any issues with my FRM once its back in my car? For example, will it have to be recoded or anything like that? I would assume its pretty much a plug and play thing but I would like to avoid bricking or messing up my FRM.
