Intelligent key features a smoothly rounded design for convenient carrying. Door lock/unlock and trunk open are equipped with sensors to detect the intelligent key within a range of 80cm.

Tucked neatly inside the Intelligent Key shell is the mechanical key for traditional locking and unlocking. The mechanical key may also be used to activate the ignition.

The TEANA ignition can be switched on or off without a mechanical key. As long as the Intelligent Key is near the ignition knob the driver can turn the switch and start the vehicle.
