I have a 2003 Hyundai Sonata and the power locks in it won't work. At first I thought it was the key but the unlock button works. The lock button doesn't work in neither the car not the remote. Is it just a bad fuse or is it more complicated than that?
The owners manual will give you a list of the fuses and what they opperate. It would be unusual to have the fuse to the lock mechanism be different than the un-lock fuse. There must be a universal lock component somewhere that is the culprit. Could be a loose connection , burned wire or a short. I wouldn't know where this component would be on a sonanta. You would need a Haynes or other repair manual to know where this component would be.
