Yes. I use various cartoon and movie print lanyards for my work keys. Currently using a Nightmare Before Christmas lanyard. I use an AmeriCorps Energy Express lanyard for my personal keys
I haven't had one since I first started working at Walmart back in 2012. Though it kept getting in the way every time I needed to bend over, so I just tossed it.
Both sets of keys have a lanyard. One looks like the Gryffindor tie from Harry Potter (although I'm more of a Hufflepuff—it was a gift), and the other has the state university's logo. I've had the latter since I first started driving, although I never ended up going to college.
