How do you reset a Hyundai Santa Fe immobilizer?

To reset the immobilizer on a Hyundai Santa Fe, first, ensure that you have the correct key fob. Insert the key into the ignition, turn it to the "On" position without starting the engine, and leave it for about 10 minutes. After this, turn the key back to the "Off" position, wait a few seconds, and then try starting the engine. If the immobilizer light goes off and the engine starts, the reset was successful.
