Why would a dwarf make a magic passcode, let alone one in elvish.
Because the door was made during a time of friendship between dwarves and elves. The door itself was made by Narvi, a dwarf, while Celebrimbor (yes, that Celebrimbor) carved and inlaid the letters.
The doors were made to be used by both dwarves and elves, and since the dwarves do not teach their language to outsiders, the letters had to be elvish.
Also, you should read the books. And the appendices. And the Silmarillion. It’s a fantastic world (and the books are different from the films in many regards).
