Hi, I have an Ef falcon.  I have an aftermarket alarm with remote
entry.  It is hooked into the central locking, but I don't think it is
related.  Basically, when I lock the doors, the driver's door isn't
actually locked.  The two buttons go down on the doors and the other
three doors lock, but the driver's door can still be opened from the
outside.  It doesn't matter whether I lock the car with the remote or
by pressing the button in the car.  If someone could give me an idea
as to what the drama is, that would be great.  Thanks, Mic.
