Can a repo man break into garage to repo a motorcycle

First its not a good idea to piggyback your question on someone else's. This can lead to confusion. You should start a new thread. So I've moved your question to its own thread.

No, they cannot break into private property.

They can not legally break into.
Bt then I know many that don't mind bending the law, and once they have it, merely lie about breaking in.
