the security light has nothing to do with your alarm. It's the VATS system in the key. The value it read from the key did not match what the car was expecting to see. It could be the key cylinder going bad, but one easy thing to check first is the ground connections at the top of each kickpanel. If they are a little loose, the BCM can not get a good reference to ground, and will not get an accurate read on your key.

Another cause could be that the module on the key got dirty or wet causing an incorrect read. Wait 20 minutes or so. It should be ok after that.
