Driver side door won't unlock with keyless entry
 

Okay first off this is a buddy of mine at work that's having an issue with his FR-S.

It was a cold night came out the morning try to unlock the car the driver side door wouldn't unlock on the passenger side and when he turned the car over after using his manual key to get in the driver side door his windows wouldn't work so he had to reset them.

Is there a way to determine if the little actuator went bad or is it needing to be rekeyed, I told him he might need to pull off the door panel to check the connections but he is not very mechanically inclined.

I've had this issue when I've locked the door from inside using the door button. Somehow the system got confused. I had to hit lock and then unlock on the remote. Seemed to help.
