Ballers

Spencer Strasmore (dwayne the rock johnson) comes back to his old firm to try and buy his former division in the company.  He brings a million dollars cash with him to make a statement with his offer.  He has the money in a fendi man-bag, what else would you put a million dollars cash in.  The bag has a light bulb keychain (bag charm) on it.  This keychain is made from sheepskin.  These keychains are more of a bag charm but they have key rings on them and can be used as a keychain.  So I am going to count it as such.  I have added a closeup picture of that keychain, it is a different color though.

This was most likely put in the show as product placement as are most of the other clothes and fashions.  Designers will quite often give their clothes to shows so they get screen time and publicity.

Zootopia

Judy Hopps cracked the case and races back to Zootopia.  She takes her parents farm truck.  Their keychain is a felt (fiber art) carrot.  Quite appropriate for rabbits that are carrot farmers.

Last Man on Earth

From season 3 episode 1.  The group is trying to flee their malibu mansion due to an unexpected arrival of armed people.  Their cars are blocked in by the A team van that Todd was driving.  They frantically search for the keys while Todd describes the Mr. T keychain in great detail.  They find them but not before the outsiders greet them.  The keychain is a Mr. T figure and a talking device with appropriate catch phrases.

From season 4 episode 18.  Tandy Phil Miller (Will Forte) gives the key to an RV, to his Brother (Jason Sudeikis) so that he can leave and find more people.  The keychain features a Mexican flag behind the Virgin Mary.

Star Trek: The Next Generation

From Star Trek: The Next Generation season 2 episode 12.  Riker, Data, and Worf are investigating a strange alien structure on a planet.  They beam down to discover it is a recreation of a pulp novel where the setting is the Hotel Royale.  They receive room keys from the front desk and are confused by the ancient keys and keychains.  They most likely have never seen anything like them before.
