Mechanical Key

If the remote key does not operate normally, you can lock or unlock the door using the mechanical key.
To unfold the key, press the release button, and the key will unfold automatically.
To fold the key, fold it manually while pressing and holding the release button.
NOTICE
Do not fold the key without pressing the release button. This may damage the key.
Remote Key Precautions
The remote key will not operate if one of the following conditions occurs:
- The key is in the ignition switch.
- You have exceeded the operating range limit (approximately 30 m [90 ft]).
- The remote key battery is discharged.
- Other vehicles or objects may block the signal.
- The weather is very cold.
- The smart key is located near a radio transmitter, such as a radio station or airport, which may interfere with normal operation of the smart key.
If the smart key does not operate properly, lock and unlock the door with the mechanical key. If you experience problems with the smart key, it is recommended that you contact an authorized HYUNDAI dealer.
If the smart key is placed in close proximity to your mobile phone, the signal may be blocked by the normal operating signals of your mobile phone.
This is especially likely when the phone is active, for example when making and receiving calls, sending and receiving text messages, and/or sending and receiving e-mails.
Do not place the smart key and mobile phone in the same location, and always try to keep a sufficient distance between the two devices.
