Yes you should be fine. And it's just the key shutting off that's the problem, the "car" (meaning the engine) is going to be off this entire time anyway.

As long as you don't turn the key off, the ECU stays in flash mode, so you just flash it again until it goes through successfully.

Now I would still fix the OBD port to be on the safe side, because this isn't something you want to mess around with more than necessary, I just wanted to make you aware that if the flash fails because there was an interruption part way through, usually you can just flash it again and be just fine, as long as you leave the key on.
