Have a 2008 Accent that sometimes the remote will not unlock the doors. Dealership can't get it to mess up for them. Anyone know what's going on. New battery in remotes and car. Reprogramed both remotes. This has happen 6 times.
Where is the car when it happens? In the driveway? In the parking lot @ work? At the mall? Everywhere? Possibly if its just one place you have a source of interference that's causing it. Or perhaps its a tempeture isse does it happen only @ night or early in the morning? Perhaps that might giv you some things to think about at least if you can give us a bit more inpit perhaps we can help more. Do your corner lights flash when you have the problem or is it like you never pushed the buttons? How far away from the car are you when your hitting the buttons?
