Otherwise the other three doors are accessible and may be closer to an attacker. I got that from my sister.



Same reason that some (most) keyless entry systems nowadays have you press once to unlock the driver's door only and press again to unlock all doors. A nice feature. I don't know about you guys but if I'm in a sketchy lot at night I lock the doors while in the process of entering the car - the lock button seems to be positioned just right for reaching at that angle

I'm curious as to why some people's cars can unlock all doors with the key, I never knew it to be a Contour feature. Did you all have aftermarket alarms that added it or something? The feature would require an electric signal from the key turning to unlock all doors, seems to be more expensive than is worth it.
Also, was it "turn once and the drivers' door unlocks and turn twice and the rest unlock" or "turn once and all unlock"? (The latter would explain possible glitches or crossed wires in the locking system, the former is, well, sweet that you had it!)
