I decided I should do this at least once, so if it were ever necessary I could do it, even a moment of stress because I'm locked out and the FOB won't unlock the door. Carefully read the OM to see what it said, sadly not enough apparently. Pushing the button in with the key, so the cap could be lifted off was straight forward. The key fit just fine. Rotated it 1/4 turn counter-clockwise to unlock the door. The key turned just fine, could feel and hear mechanical things happening in the door. Pulled the handle to open the unlocked door? Nada! Handle pulls out okay, but door is still locked. Turned the key clockwise back to center then 1/4 turn more clockwise. Again it turned easily and I could hear things happening inside the door. Pulled the handle to open the locked(?) door, not expecting much. The alarm went off! Push the alarm button on the fob to turn off the alarm, NOPE! That now won't shut off the alarm? Turn the key back and forth to lock and unlock the car, still alarming. Neighbors starting to stick their heads out the door to see what's up. Pushed the black button on the handle to unlock the driver's door. That unlocked it and turned off the alarm????? Just to make sure fob is okay, tried later to engage the alarm with the key fob. Worked fine and shut off on the second alarm button push. At this point all I am sure of is that if the fob fails to unlock the car, I don't think I can unlock it with the key - although the key turns in the lock. . . . . I haven't tried putting the fob in a foil bag and taking just the key to the car and trying to unlock it to simulate a broken / lost fob. Perhaps if the key is used to "unlock" the door, the door handle button still needs to be pressed to complete the unlock process? Anyone else run into this? Surely I'm just doing it wrong somehow?
