I have a 2003 Honda Accord 4dr, ok when I use the key fob(s) to lock the doors, the doors wont lock, but if I lock the drivers door using the key and then push the lock on the key fob then the other 3 doors will lock and I only then I can alarm the car. I can lock all doors from the inside using the door lock switch. Is it a key fob(s) issue or is a an accuator problem? This is just Too Weird...

 

There was a post today about the multiplexers having to be reset. This was for a 98, but it may work with your accord. Your owner's manual may have the reset procedure for your 03 accord. Let us know what you find.

Well I did try resetting the multiplexers but it did not work, so I guess 03 don't have that feature. I set the wiper intermitter control ring to the middle position and then turn the key to the on position so that the guage lights come on and then I turned it off. closed the door and tryed to lock the door with the key fob. All doors lock but the drivers door. So what do you think is wrong now?

 

I'll have to check (I still have that Helm book...)
I think 2003 begins with the CAN bus, instead of the multiplexers.

Multiplexers were a preliminary type of distributed control for stuff like windows & locks. The CAN bus takes that a step farther & it's basically computer control for all that stuff.
