More info needed. could be many things.

Let me guess, bad battery ??? could be that or something electrical

Maybe try and pull the correct fuses and reset the computer and see if you can clear that out of there, just a suggestion.

common gm failure for the security light is a failed pass-lock sensor, (lock cylder), ...just a guess, could be many things, but this will turn on both lights,
