El Camino: A Breaking Bad Movie

This movie picks up right where Breaking Bad left off and follows the rest of Jesse Pinkman's (Aaron Paul) escape.  At the end of Breaking Bad Jesse drives off in Todd's El Camino, his keychain can be seen, a bottle opener, this the same keychain that can be seen in the final episode of breaking bad.  Jesse switches cars with his friends. Badger and Skinny Pete.  Skinny Pete's keychain is a die (single for dice) and a generic fob.  Badger's keychain is a posable hand.

Ash vs. Evil Dead

In the final scene of the series, the keys to Ash's Oldsmobile Delta are thrown to him.  His keychain is a bullet (a mainstay for badasses) and a skeleton arm which is just a perfect fit.  This keychain is throughout the show but not easily visible.

Always Be My Maybe

The Netflix movie Always Be My Maybe is a romantic comedy about childhood friends.  Marcus (Randall Park) is reminiscing about his past friendship with Sasha (Ali Wong) after he sees her for the first time in years.  He looks at a souvenir keychain they got at a fair with a picture of them inside it.
