Smart key precautions
The smart key may not work if any of the
following occur:
The smart key is close to a radio
transmitter such as a radio station or
an airport which can interfere with
normal operation of the transmitter.
The smart key is near a mobile two
way radio system or a mobile phone.
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.
