A new BCM self-programs to match the first ignition key used after installation. After that it cannot be reprogrammed. When you install a new BCM, simply insert your existing ignition key, turn it to the RUN position (don't actually start the car), wait for the normal warning light self test to complete (about 10 seconds) then turn off the ignition. Your new BCM is now programmed to match your key and the car will start normally.
However, if you're referring to the outside lights when you say that they are staying on, that is not related to the BCM. The BCM handles door locks, retained accessory power for windows and radio, rear hatch release, various warning lights and chimes, interior courtesy lights, VATS, keyless entry, and the optional alarm system. Exterior lights are not related to the BCM except for the alarm flashing the parking lights when triggered.
