• Another vehicle's smart key is being
operated close to your vehicle.
If the smart key does not work correctly,
open and close the door with the
mechanical key. If you have a problem
with the smart key, it is recommended to
contact an authorized HYUNDAI dealer.
If the smart key is in close proximity to
your mobile phone, the signal could be
blocked by your mobile phone's normal
operational signals. This is specifically
relevant when the phone is active such
as making and receiving calls, text
messaging, and/or sending/receiving
emails. When possible, avoid keeping the
smart key and your mobile phone in the
same location such as a pants or jacket
pocket in order to avoid interference
between the two devices.
