Hello and welcome to the forum. If you or a family member has a button battery stuck inside your ear canal, you need to receive prompt help to remove that. An urgent care or emergency room is suggested. Trying to remove on your own with something like a Q tip is a bad idea as it can push it further into your canal. Foreign objects in the ear can cause irritation, infection or hearing loss. While it is not a serious emergency, it does need to be removed and within a day is ideal.
