Airsoft guns are considered firearms for purposes of the criminal code, so unless something negligent happens they don't have to be "locked up". That being said, they shouldn't be easy to steal or able to attract attention. Your living situation is unique so it's up to you to take care of it. However, let's say there was a search of your house, for something unrelated, and airsoft guns were found loaded in a bag in your closet, you shouldn't get in trouble like it was a real firearm. Remove battery, remove ammo, it is now a paperweight. It was a good question though.
