DOOR_CHILD_LOCK_ENABLED

What it is

Door child lock feature enabled

Returns true if the door child lock feature is enabled and false if it is disabled.

If enabled, the door is unable to be opened from the inside.

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 0x16200b03 apart:

Field	Mask	Value	Means
Group	0xf0000000	0x10000000	SYSTEM
Area	0x0f000000	0x06000000	DOOR
Type	0x00ff0000	0x00200000	BOOLEAN
Ordinal	0x0000ffff	0x00000b03	0xb03

Reading it from an app

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

boolean value =
        mgr.getBooleanProperty(VehiclePropertyIds.DOOR_CHILD_LOCK_ENABLED, 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.
