@luckykey3,
Not knowing what your search title is or what category yo choose when searching for the key chains are, it's hard to say why they are harder to find and more expensive. Instead of searching for keychains, you might want to try key rings in clothing shoes and accessories.
I found a fair number of those items listed using a couple of different searches, and yes some are high priced. The reasons for that could be, the suppliers aren't making as many anymore. The sellers have no stock but instead of ending the listings they raise the price (typical chinese seller trick) Shipping costs have risen....
As for your comment:
Most individual ebay sellers have no photographic training, so they do not think of the consequences when photographing white items on white backgrounds. They will also use their flash when photographing shiny items, or when they are too close to the item, and other mistakes.
Product photography takes time to learn, and most don't take the time to try to figure out how to take the photos correctly. A lot of them use their phones for taking the photos as well. Phone cameras do not offer enough features to do product photography correctly, they are designed for general photography, like scenes or selfies...
