My keyless entry system just starting having some issues. Sometimes when I go to unlock the doors they'll unlock for a second and then immediately relock themselves. Other times it will happily unlock the driver's door but then it will do the crazy unlock/lock thing when I hit the button again to open the rest of the doors. The fob always locks the doors though. I replaced the battery in the remote and its still having that same problem. This problem isn't described in the FSM so I'm hoping someone here has an idea.
