A person a can open the rear door from the inside. Get into the car from another door that will open and open it from the there.
Something is wrong with your rear door and it is not closing properly in the first place. Your door lock actuator is broken, it will need to be replaced.
replace the door or buy a new car.
door lock actuator stuck,bad door latch if rear door has child saftey on a bad door entry handle.
Don't open your car door into traffic. Use the other door.
The person in the car is to blame because the person riding the bicycle would have no way of telling when the car door would be open. the person in the car could have easily looked in the side mirrors and could have seen if someone riding a bicycle was passing by.Added; The traffic offense charge would be "Opening Door to Traffic."
You would firstly have to get a REALLY BIG door, as the sub will require the space for the bass.
You buy a new motor for the window or open it using the switch beside the driver door (if it is a relitively new car).
If you are talking about the rear door ,then the answer is that there is a small (child) safety pin at each door,you can see it very clear,just turn it to the other side. S.Benjamin
The key would be favorite.
rear washer spills water. check it first.
On my C3, there is a sticker on the inside of the passenger front door, visible only with the door open, if I remember rightly, it is 2.1 BAR front and rear for an empty car, and 2.1 BAR front and 2.5 BAR rear on a heavily loaded car
