Record your key number
Hyundai Sonata / Sonata 2011 Owners Manual / Features of your vehicle / Keys / Record your key number
The key code number is stamped on the bar code tag attached to the key set. Should you lose your keys, this number will enable an authorized HYUNDAI dealer to duplicate the keys easily. Remove the bar code tag and store it in a safe place. Also, record the code number and keep it in a safe place (not in the vehicle).
