Yup. Mine unlocks no matter what you do from the drivers door. The passenger door still works, so being basically lazy, I lock up with this door. Occasionally it acts up also. When that happens I lock the door by pushing down the lock (with the door open) then inserting the key and holding it in the lock position as I shut the door. This seems to be the failsafe method to date.
What needs to be done is a simple redjustment of the locking arm that connects the key throw to the electric switch box.
But I am lazy... :|
