Keyless entry on one door not working.
 

2014 Civic, when approaching the car door, the door usually unlocks, this works on the passenger side but not the driver side. The remote unlocks all the doors when the button is pressed but acts like I'm not there when I approach that door.

If I press the button on the driver door, the light on the remote does blink but still not working as expected.

Appreciate any help.
