I'm a newbie here. Hello Hyundai owners
I changed the battery in the key fob. Now the fob doesn't lock or unlock the car. How do I reprogram the fob?
I have a car with the key on the dash light. The power driver's seat doesn't extend anymore. I can set the AC on cold,turn down the dash lights. Turn the car off,& on again. The AC will be at 73°,& the dash lights will be on high. The radio will also change. All of the above issues have all started after I changed the battery in the fob. I went to the dealer. Tech removed both battery cables,& touched them together to short out the car system. I still have the above issues. Can someone please tell me how do I fix these issues?
