I remote started my santa Fe and the doors would not unlock. I pushed unlock button many times. After a while I decided to use the key to open the driver door. I inserted the key in the ignition and turned it to the ON position. I drove home and when I turned the key to off position the engine did not turn off. I tried several combinations on the fob, turned the key on and off, shifted from park to drive. Nothing has worked. Has anybody experiences this? Any suggestions?
