DOOR_LOCK

What it is

Door lock

'true' indicates door is locked

This property is defined as VehiclePropertyAccess.READ_WRITE, but OEMs have the option to implement it as VehiclePropertyAccess.READ only.

How the ID is built

A property ID is a 32-bit value packing four fields. Reading 0x16200b02 apart:

Field	Mask	Value	Means
Group	0xf0000000	0x10000000	SYSTEM
Area	0x0f000000	0x06000000	DOOR
Type	0x00ff0000	0x00200000	BOOLEAN
Ordinal	0x0000ffff	0x00000b02	0xb02

Reading it from an app

CarPropertyManager mgr = (CarPropertyManager)
        car.getCarManager(Car.PROPERTY_SERVICE);

boolean value =
        mgr.getBooleanProperty(VehiclePropertyIds.DOOR_LOCK, areaId);

This property can be read and written, though an OEM may implement it as read-only. It fires a callback whenever the value changes.
