Cosmic Car Key

The Cosmic Car Key is a Hardmode mount-summoning item. When used, it summons a rideable UFO that allows the player to fly and hover indefinitely. It has chance to be dropped by the Martian Saucer mini-boss during the Martian Madness event.

Tips

 * When using this mount, it may be useful to replace other mobility accessories such as any Wings or Boots with damage- or defense-based accessories.
 * While they lack infinite flight time (unless the is used), using wings with hovering abilities in tandem with Lightning/Frostspark/ can provide more speed and mobility.
 * Using wings with a fast ascent speed such as Jetpack, it is possible to fly upwards with the wings, deploy the mount and maintain the speed of the wings beyond the duration of the wings.
 * Using the Rod of Discord can be a great way to travel while using this mount, as you can teleport through tight areas rather than dismounting the UFO.
 * It's possible to give this mount to another player while mounted and still keep using the UFO.
 * The mobility of this mount and the ability to use items while riding it make it a good mount for construction.
 * If one needs to have an infinite flight mount underwater, the Cute Fishron Mount or the are good replacements for the UFO.
 * This mount may not be the best to use in an arena for intense boss fights (such as the and Moon Lord), as its infinite flight time is overshadowed by its not very fast speed, lack of dashing ability, and slow turning speed. It may be preferable to use the Cute Fishron with Honey and Water bubbles (which has a very fast speed along with boosting damage by 15% when in and shortly after leaving liquids) or to not use mounts at all and instead have the, the Expert mode-exclusive drop from the Empress of Light, which provides infinite flight time.

Trivia

 * The buff tooltip is a reference to the film Independence Day, in which a Macintosh computer is used against an alien spaceship.
 * The name of the item might be a reference to a line in a rant about the insanity of everyday life by Eric T. Duckman from season 3, episode 6 "A Room with a Bellevue" from the American adult animated sitcom Duckman. The line goes, "...knowing when it's time to flash the cosmic car key at those Pearly Gates, I won't be in the coffin anyway...".
