Default Replace PCM in 2000 L-series wagon

I'm trying to change a PCM (engine computer) on a saturn 2000 L-series wagon. The old unit starts and runs the car but is giving intermittent service lights. The new unit won't start the car and while cranking the security light blinks. Is there something special about changing the PCM I don''t know about? Thanks --- Mike
