a virtual network formed of said first wireless control node and said second wireless control node, said virtual network enabling said first wireless control node and said second wireless control node to communicate with each other and to actuate said first plurality of said devices and said second plurality of said devices, respectively; and

a third wireless control node positioned external to the vehicle and capable of becoming part of said virtual network so that said third wireless control node can communicate messages to at least one of said first wireless control node and said second wireless control node, said at least one of said first wireless control node and said second wireless control node utilizing such messages to further control the functioning of at least one of the devices within the vehicle, wherein:

the vehicle includes at least a driver door and a passenger door,

said first location being associated with said driver door,

said second location being associated with said passenger door,

said first module and said second module further including at least one manual controller coupled to the devices of said door associated with each of said first module and said second module,

each manual controller configured to provide messages to control at least a selected one of said associated devices in response to an operator actuating one of said manual controllers,

said first module further including a first manual controller coupled to said first wireless control node and configured to provide messages to said first wireless control node in response to the actuation of said first manual controller by the operator, and

said messages from said first manual controller being sent by said first wireless control node to at least one other wireless node to control a device coupled to said other wireless node in response to said actuation of said first manual controller.

2. The apparatus of claim 1 wherein said first wireless control node and said second wireless control node communicate with each other in accordance with a Bluetooth wireless standard.

3. The apparatus of claim 1 wherein said vehicle further includes:

a plurality of other systems performing a different function relating to the operation of devices of the vehicle;

a data bus for communicating with each of said other systems; and

a gateway for communicating between said data bus and at least one of said first wireless control node and said second wireless control node.

4. The apparatus of claim 1 wherein:

each of said doors having a door lock associated therewith; and

said devices associated with each of the doors includes a door lock motor that is mechanically coupled to each of said door locks and said door lock motor being adapted to perform the functions of locking and unlocking said door lock coupled thereto in response to a set of messages from said third wireless control node.

5. The apparatus of claim 4 wherein said third wireless control node is a key fob.

6. The apparatus of claim 1 wherein:

each of said doors having a window and a mirror;

said devices associated with each of the doors also including a window motor and a mirror motor for respectively operating said window and said mirror;

said window motor being adapted to perform the function of moving said window in response to a set of said messages from said first wireless control node; and

said mirror motor being adapted to move said mirror in response to another set of said messages from said first wireless control node.

7. The apparatus of claim 1 further including:

a third module positioned at a third location within the vehicle, said third module having a fourth wireless control node;

a fourth module positioned at a fourth location within the vehicle, said fourth module having a fifth wireless control node;

additional devices being coupled to each of said fourth wireless control node and said fifth wireless control node;

each of said additional devices being adapted to perform a predetermined function in response to a selected message from said wireless control node coupled thereto; and

said fourth wireless control node and said fifth wireless control node being adapted to form a virtual network with each other and with said first wireless control node and said second wireless control node so that said wireless control nodes can communicate the messages to each other to enable some of said wireless control nodes to utilize the messages from others of said wireless nodes to control the function of at least one of the devices coupled thereto.

8. A method for communicating messages for controlling the functions of devices within a vehicle, each of the devices being adapted to perform a predetermined function in response to a selected message from a wireless control node coupled thereto; said method comprising the steps of:

placing a first wireless control node at a first location in the vehicle;

placing a second wireless control node at second location in the vehicle;

enabling the first wireless control node and the second wireless control node to form a virtual network so that the first wireless control node and said second wireless control node can communicate at least one message to each other to actuate a device;

positioning a third wireless control node external to the vehicle;

enabling said third wireless control node to become part of said virtual network so that said third wireless control node can communicate a message to at least one of said first wireless control node and said second wireless control node;

further enabling at least one of said first wireless control node and said second wireless control node to utilize a message from said third wireless control node to further actuate the functioning of at least one of the devices within the vehicle;

verifying that said virtual network has been formed;

authenticating that said message from said third wireless control node is a valid message;

conveying said message to at least one of said first control wireless node and said second wireless control node in response to said authentication of the validity of the message;

providing a command to a device in response to said message;

associating a wireless control node with each door of the vehicle;

coupling a manual controller to each of said wireless control nodes associated with each door of the vehicle;

adapting each of said manual controllers to initiate a message in response to actuation of said manual controller by an operator thereof; and

arranging at least one of said wireless control nodes to send said message initiated by said manual controller coupled thereto to at least one other wireless control node to control a device coupled to said other wireless control node.

9. The method of claim 8 further including the steps of:

providing a plurality of other systems in the vehicle;

causing each of said systems to perform a different function relating to the operation of devices associated with the vehicle;

utilizing a data bus to communicate with said other systems; and

enabling a gateway to communicate between said data bus and at least one of said wireless control nodes.

10. The method of claim 8 further including the steps of:

providing a door lock motor for operating a door lock associated with a vehicle door;

adapting said door lock to perform the functions of locking and unlocking said vehicle door associated therewith in response to said operations of said door lock motor in response to selected messages; and

enabling said third control node to provide said selected messages to at least one of said first wireless control node and said second wireless control node.
