my 03 wont turn over but powers up?

[Rufcar]

Today I tried on last time and the security system went off. Nothing worked to shut it off. In one of my remarks I thought I mentioned this happened the last time 2 weeks ago but I was able to shut it off. The key fobs never worked. I did manage to get the fob lights to work today but probably needs programming which I am told cant be done with the security system on. The horn blew until the system shut off until I get back in the car tomorrow to load it. Any last suggestions? I still believe the security system is the problem? Yes? Tkx Jim
