ok i have hyundai's factory alarm but i went to my local stereo shop to get a remote start added to my car and the guy told me i need a bypass module where my spare key goes in but is this true? is is dei model 556u the one he said i needed so let me know.
I was told my 04 needed one, but it turned out it didn't. I'm not sure about the 06 but US models didn't have them in 04. I ended up buying one before I figured out I didn't need it, so if you do need it I'll sell it to you cheap.
