I have a 2000 cadillac seville sts I shut it off Tuesday went to start it last night and all it does is roll over and nothing else. Everything else works so I am baffled

What is your question?

I am told it is the security system but I think it is people making a guess everything else works as should it just will not start when it rolls over

How long has your 2000 Cadillac Seville had this problem?

one day
