Ordered these from Ebay, costs about 10 bucks to do it, just throwing it out there if anybody finds it old. My cold car had a flip out key like this and i quite missed it. It uses the same components in ur original key and you cut a new key for it at a shop for about 2 bucks or so. Sry if I messed up, this is my first post, and I have quite a bit more to post if people find this stuff interesting.
The Second link is a sticker, for the back of the remote key, a little space for it. You can rock it without it if you like tho aha.
