if key not opening than you have an internal problem which you need to open door and remove door panel go around and enter vehicle from passenger side and open door behind door panel are rods with clips that operate release their are also spring on latch itself but usually the clip breaks or becomes disconnected most auto stores carry a replacement clip

you can have a shop reprogram the reciever in the car to accept the remote. once the battery is removed from the remote it resets the code it transmit (Rolling code)

Hyundais have the tendancy to blow the ignition switch, yours was probabbly replaced, and by doing so you will need the Original key the car came with, not the new one included in the kit for the ignition switch.. also have you checked the little battery for the keyfob??? it probabbly went dry.

best regards!

It's probably the key fob battery. Why can't you sue your ignition key to unlock the door?

their is no doubt some way to reset it by turning the key so many times left and right ?? but try this ,and that put key in drivers side lock and lock and open three times slowly then open door on last attempt and try to start within 15 secs of opening the door lock ,also try the spare key in case the chip has fallen out of the key ??

The solution is to pull out the back seat to get into the trunk. There are two bolts holding the bottom part of back seat (bolts located between bottom and top sections). Then pull out bottom section of back seat and you see the hinge for the top section, remove the bolts and then you can lift up and access the trunk. It's not that hard.
