I've had this in all 3 of my S/V40's and when you can't lock the driver's door via the key or fob the best workaround I've found (short of replacing the offending component) is to:

1. Ensure the doors are unlocked so the other three buttons are "up", the

2. Pull the driver's button up with some pliers or a multi-tool to re-set it.

I've found that it will then start locking again & if you lift the drivers door handle when the car's locked that won't instantly open the door.

Sidenote: this problem NEVER happens when my wife locks or unlocks the driver's door, only when I do it! She said I unlock it too quickly and, funnily enough, when I unlock it S-L-O-W-L-Y then, yes, I don't have a problem with the lock and the button rises and falls as it should.

So perhaps being more gentle might help you guys too!
