Take it to the delaership, or stealershiip as I like to call them. You can't reprogeam the BCM without the special scan II tool.

SOURCE: Buick Rendezvous 2002 need codes?

the BCM needs to be programmed to operate the computer. a GM techII is now required to calibrate BCM to airbag, stereo, keyless entry, and control pcm data. This is required to make it all work. a gm service should have it done within an hour or less just call and ask them how much it would be to program new BCM. it might cost @$75 to $125 but it is needed, to allow the BCM to work properly.

what you need to do is pull the radio out and write down the serial number then call the dealer for the code. they may charge you 15-25 bucks but that will save you some money
