A : Door handle authentication pad,
B : NFC Antenna

To unlock:

Place the digital key (card key) near the door handle authentication pad of the driver or passenger side door for about 2 seconds.

If you unlock your vehicle from the passenger side door handle, all the doors are unlocked. If you unlock your vehicle from the driver side door handle, the driver door only or all the doors are unlocked depending on the setting of the Two Press Unlock feature. Refer to User Settings to change the Driver Door unlock mode.

To lock:

Place the digital key (card key) near the door handle authentication pad of the driver or passenger side door.

Before you leave your vehicle, check that your vehicle is locked. When using your Hyundai digital key on the front door handle, listen for the door lock to actuate, and then pull the handle within 3 seconds to confirm the doors are locked.


  • Always take the digital key (card key) out of your wallet or purse. If the card key does not touch the door handle authentication pad or is near other NFC-enabled cards, it may not work properly.
  • You cannot lock your vehicle if: - The Smart Key is in the vehicle. - The Button Start ignition switch is in the ACC or ON position.
    - Any door is open (except for the liftgate).
    - The vehicle battery is discharged. A chime sounds for about 3 seconds. Move the card key more than 4 inches away from the door handle sensor and then try again.
  • When the doors have been unlocked using the Hyundai digital key, and you attempt to lock the doors using the driver door lock switch, the doors are locked and then immediately unlocked when you close the door.


  • If the digital key (card key) is damaged or bent, the sensor may not detect the digital key (card key). If this occurs, contact your authorized HYUNDAI dealer for a digital key (card key) replacement.
  • Be careful not to damage the digital key (card key) or expose the digital key (card key) to extreme temperatures or direct sunlight for a long time.
