Hyundai Equus: Keys

Your EQUUS uses a Smart Key, which you can use to lock or unlock a door (and trunk) and even start the engine.
1. Door Lock
2. Door Unlock
3. Trunk Unlock
4. Panic
WARNING - Smart key
Leaving children unattended in a vehicle with the smart key is dangerous even if the Engine Start/Stop Button is in the ACC or ON position. Children copy adults and they could press the Engine Start/Stop Button. The smart key would enable children to operate power windows or other controls, or even make the vehicle move, which could result in serious bodily injury or even death. Never leave the keys in your vehicle with unsupervised children, when the Engine is running.
