As long as I have the key in my pocket, I can open my car boot only, unlock the whole car, lock or double-lock the whole car, start the car and switch off. No buttons to press, just touching a front door handle in a certain way to unlock and lock, no ignition key in a slot. I know I've locked the car because the wing mirrors fold in. If I accidentally unlock the car as I walk away from it by fumbling around in my pocket for the key or something, the car re-locks itself very quickly unless I've opened a door. I can use the key to do all the locking and unlocking if I want, but I can't be arsed. My car is a three-year-old Focus Titanium.
