I have turned the key, too, and had to clear the code later.

But just as a word of caution, the proper way is to disconnect the battery and wait some minutes to make sure the airbag system is de-energized before working on the airbag. After the airbag is unplugged and set aside, you can re-connect the battery if you need to move the window.
