The Ministry of Science and ICT of Korea recently updated the “Technical standards for radio equipment for radio stations that can be established without reporting” and allowed additional purpose of “notification” for use of 433.795 ∼434.045MHz.

Now this band is allowed for uses of "Tire air pressure alarm system for automobiles, opening/closing, notification, starting or parking systems of automobiles".
