On my 2008 Hyundai Accent the passenger door stay stuck it won't open unless you use a key on the outside of the door.
What could be the problem
The cable from the door handle to the latch could be the problem.
Have you removed the door panel??
Yes I removed the door panel . Why could that cause it ND how can I fix it.
Did you notice any issues with the cable? The cable can break. If that's not the case then I would replace the door latch.
Well the cable seems to be there ND not broken I want to say cuz the lock frm inside won't unlock it's feels like it's stuck or something but until I insert the key on outside of the door ND hold the key to the left I could open the door frm inside or out.
