usually with older European cars, when there is a external boot opening switch, AND there is a key hole on the boot lid (or near it), but NO lever near driver's seat. So usually the only way to open the boot is through that external button if the boot is not locked. If it is locked, then u need to unlocked it with the car key. (a bit inconvenient if the ignition is on).

While Japanese cars usually come with lever swith beside door seal of the driver's seat. AND a key hole near the boot lid, but No external button. so to open the boot, u need to insert the key in to that key hole and turn it. Or use the lever beside driver's door.

Of course above two cases applied to those cars BEFORE remote control keys are available.
