I don't know a whole lot about Hyundai's myself (I'm a BMW guy), but my sisters 2003 Tiburon GT V6 has what I think is a small problem to fix. The batteries died in the alarm remote, and now after replacing the batteries, the remote won't work. Does the remote just need to be re-set; if so, does anyone know how to do this? She doesn't have the manual, and she's in Ohio (I'm in California). I've done this in my dad's 528i. Thanks!

The keypad also isn't working, maybe that's a just a fuse?

 

Try flipping the battery around and cleaning the contacts inside the remote with some Isopropyl alcohol and an old toothbrush. It doesn't need reprogramming. Hope this helps.

 

Thanks, I'll have her try that out.
