The Walking Dead Season 4 Episode 4

The group encounters some walkers in a auto shop and one of the members reaches for whatever is near.  In this instance it is a bathroom key with a screwdriver/icepick (hard to tell exactly) keychain.  Keychains save the day again.

Later Rick is prepping a car for a quick getaway.  They keys are in the ignition and the keychain is some kind of vinyl fob.  It is in the shape of the state of Georgia, which makes a lot of sense since the show takes place in Georgia.

Key & Peele L.A. Vice Sketch

Peele's purple rabbit's foot keychain can be seen for extended periods in several overly dramatic shots.
