so i didnt know this until a few weeks ago when i was at the dealership (and this may not help you since yours is three years older, i have an 06) but whenever you unplug the battery for say, an electrical mod, it wipes out the memory in the cars computer. thus losing the programing to the remote.
hope that helps you, or someone else like me that didnt know.
Hmmm, I haven't unplugged the batter since I have owned it. (Which has been 2 weeks now)
But the battery has been recently replaced according to the owner, so maybe something went wrong with the setup? I guess I get an idea when I take it to the Hyundai dealership.
yeah they are weird I have the same dilemma. If it was working before, I recommend making sure the little rubber bumper under the hood is making good contact with the trigger plunger under the hood, if not buy a new one, those things get compressed with time. Next get your little transmitter open it up and test the battery, if its good, make sure the battery housing did not separate form the board, if it did you don't have to re-solder it, just make sure the two contact pins are going through the board....then put a folded piece of card material in there to keep the battery housing in contact with the board. The push togethet the key fob and test it out. If it lites up.
Go to the tib, unlock the door manually, start the tib, shut off engine, turn key to
ACC, press lock button and keep repeating this process till u get the front and rear emergency lites to flash, they are the same lites for the keyless entry.
Gotta get those lites to flash for the fob to work.
