2001 Alero Warning Lights and gauges wont work

I had an issue with my ignition so I replaced the switch and cylinder. Afterwards it would not turn over so I reset the Pass Lock and it started right up, but now none of my warning lights come on except service engine soon when starting and then it goes off. Also none of the gauges are working either, and I also noticed that the lights for my rear defrostwer and a/c and all those other little lights for the climent control are not working. Can anyone tell me whats wrong? P.S. I have checked fuses and also removed gauges and center consil to make sure everything was connected properlly.

Bad BCM?
