So I have a aftermarket (Crimestopper) car alarm. Unlocking the car with the remote unlocks all doors. My girlfriend and her sister have newer Hyundais with factory remote, and one press unlocks the drivers door only, then a second press unlocks the remaining doors. Is this possible on the 04 Sonata? I need to first find out if it's possible then I can contact the alarm / alarm dealer and see if they can tie it in on the aftermarker alarm.
Thanks :)
