Restoring encrypted tape at DR site

I'm contemplating encypting my tapes using hardware encryption and the encryption key generated by Backup Exec.  At my DR site I am just guaranteed to have LTO-4 drives (no specific make/model).  If I do a fresh install of Backup Exec at the DR site and then generate an encryption key with the same passphrase that was used to generate the key that was used to backup up the tape, will I be able to restore the tape?  If not, what procdures will I need to put in place to ensure that I can restore the tapes at my DR site?
