How do you fix fob problem Kia Sorento?

To fix a fob problem with a Kia Sorento, first, check the battery in the key fob and replace it if it's dead. If the fob still isn't working, try reprogramming it by following the vehicle's manual instructions, which typically involve turning the ignition on and off in a specific sequence. If these steps don't resolve the issue, there may be a problem with the vehicle's receiver or the fob itself, and consulting a professional or a Kia dealer may be necessary.
