Programing can only be done once for the life of the module. A new BCM is not programmed. Before the system will function properly it must be programmed to the code that matches the keys.
I had not heard of rebuilt BCMs and I would be cautious about buying one. The BCM can only be programmed once (when new) so I would be curious how a rebuilder could get around that.

BCM --The Body Control Module is located on the right side of the vehicle and positioned under the instrument panel. In order to gain access to the module, it will be necessary to first remove the trim panel.

If I switch out Body Control module on 2003 Buick Rendezvous will my old key Work or is re-programming necessary?

If you remove any Control Module it will need programming. The Body Control Module (BCM) controls your immobiliser system so a replacement unit won't recognise the key or the vehicle and the security system will 'trip' to stop the car starting. I would suggest you pay a specialist to do this because if you get it wrong it'll cause a lot more (probably expensive) problems.

2003 BUICK RENDEZVOUS NO SPARK IN THE PLUGS, IS THERE A FUSE OR RELAY FOR THE COIL PACK

There is a fuse for the ignition control module , fuse #13 ELEC/ENG 15amp . in the under hood fuse box . The odds of the fuse being bad are astronomical . More likely that ignition module or a crankshaft position sensor is bad . There are videos on youtube on how to test gm ignition systems .

Where is the door lock module located on a 2005 Buick Rendezvous

No door lock module , BCM - body control module ! You best bet would be to take your vehicle to a qualified repair shop an have your problem diagnosed . If you replace the module it has to go to the dealer to be programed .

After some running around started the 2003 Buick Rendezvous(it started and sounded good)and the communication center went through a bunch of warning signals then I lost all dash board readings ie: heat...

It's most likely the wiring harness that runs under the body and up through the floor, located under the driver seat. Search online and you will find discussion and repair videos to help you with your issue. (It's too lengthy to go into the diagnostic and repair specifics on this forum.)
