Lost Smart Key

Smart Key Precautions

The Smart Key will not work if any of the following occurs:

  • The Smart Key is near a radio transmitter, such as a radio station or airport, which may interfere with normal transmitter operation.
  • The Smart Key is near a two-way mobile radio system or cellular phone.
  • The Smart Key of another vehicle is used near your vehicle.

If the Smart Key does not work properly, lock or unlock the door using the mechanical key. If you have a problem with the Smart Key, contact an authorized HYUNDAI dealer.

If the Smart Key is in close proximity to your mobile phone, the signal may be blocked by your mobile phone's normal operating signals. This is especially important when the phone is active, such as when making and receiving calls, exchanging text messages, and/or sending/receiving e-mails.

Do not place the Smart Key and mobile phone in the same pants or jacket pocket, and always try to maintain sufficient distance between the two devices.

CAUTION

Keep the Smart Key away from electromagnetic materials that block electromagnetic waves to the key surface.
