Additional keys can be added to putting in the car. You might be able to put a non remote key in to start the process but that is most definitely off-script and should not work for theft prevent purpose. Zero chance that would work if I did the programming.

There is no "master" key. Mechanically working key can be used to turn the ignition and then any E53 remote synced with GM. For test purposes I've used my E53 and E39 diamond keys across.
