All my functions don't work. Only the trunk and panic. Is there a way that I can reprogramm it, so that it relearns all the functions? Thanks. '11

Kia Optima models do not have keyless entry remote fob smart keys that are onboard programmable and therefore require special equipment in order to program the keyless entry remote fob smart key. Locksmith time, might want to buy another fob as a 3rd backup. Locksmith will charge about $50 to program 1-3 fobs, same price for all usually, hence got a 3rd. Luck.

Sounds like it’s defective or the battery is dead.
