look up any word, like timebomb:
 
1.
(adj.) Describes a Kleptomaniac who specifically targets keys; that person who has a strange, innate desire to lock people out of their rooms or cars.

You know you are keykleptic if everyone snatches their keys up off the table and shoves them down their pockets the second you step into the room.
"He ain't just a regular klepto, he's keykleptic! He's locked me out of my room three times this year, twice when I was in my bath robe"
