replaced battery, and alternator ran well for 2 days and now nothing. I have dash lites, but no key up for starter. battery lite turns red [ message center] and security flashes and keeps going after you pull key out of it. how to reset, or bypass. I don't want to remove cable from battery and lose any codes, what do u guys think?

The first steps are to charge and test the battery and all it's connections. Once started, have the charging system tested.

You have a problem NOW that needs to be diagnosed so now is the time these things needs to be tested.
