Your HYUNDAI uses a smart key, which allows you to lock or unlock the doors (and trunk) and even start the engine.

4. Make sure the doors are locked by checking the position of the door lock button inside the vehicle.
WARNING
Do not leave the keys in the vehicle with children unattended. Unattended children may insert the key into the ignition switch and operate the power windows or other controls, or even set the vehicle in motion, which may result in serious injury or death.

This will enable or disable the two-touch unlock function. Repeat this procedure to turn the function on or off again.

NOTICE
To avoid damaging the remote key:
- Keep the remote key away from water or any other liquids and fire. If the inside of the remote key becomes wet (from drinks or moisture) or overheats, the internal circuit may malfunction, and the vehicle may be excluded from warranty coverage.
- Do not drop or throw the smart key.
- Protect the remote key from extreme temperatures.
Mechanical Key

If the remote key does not operate normally, you can lock or unlock the door using the mechanical 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 (approximately 90 ft [30 m]).
- The remote key battery is discharged.
- Other vehicles or objects may block the signal.
- The weather is very cold.
- The remote key is near a radio transmitter, such as a radio station or airport, which may interfere with normal remote key operation.
If the remote key does not operate properly, lock and unlock the door using the mechanical key. If you have problems with the remote key, contact an authorized HYUNDAI dealer.
If the remote key is in close proximity to your mobile phone, the signal may be blocked by your mobile phone, preventing normal operation. This is especially important when the phone is in use, for example, when making or receiving calls, sending or receiving text messages, and/or sending or receiving e-mails.
Do not place the remote key and mobile phone in the same pants or jacket pocket, and always keep a sufficient distance between the two devices.
