How do you reset engine immobilizer on Hyundai trajet?

To reset the engine immobilizer on a Hyundai Trajet, first ensure that you have the correct key fob. Insert the key into the ignition and turn it to the "ON" position without starting the engine; leave it on for about 10 minutes. Turn the key back to the "OFF" position, then repeat this process two more times (total of three cycles). After the third cycle, try starting the engine to see if the immobilizer has been reset. If issues persist, consult a professional or refer to the vehicle’s manual for further assistance.
