I'm having a related problem. Using the remote, all doors unlock, but sometimes the driver's door doesn't. I can see the lock tab/button is trying to come up, but something is stopping it, as if it's rubbing. What do you think about spraying a lubricant into it?Yes, each door has an actuator. The most common problem is a failed actuator in the offending door. The next area to check is a broken wire in that door. My CRV had both issues in the driver’s door. Ensure that you order the correct model actuator as there are Japan and England versions. Japan versions VIN start with JH while English versions start with SH.
