A proper key is required to defeat the immobilizer anti-theft function and start the car. Unless terminals were reversed causing a blown fuse, the only thing i can think of that would cause a no start and security light is using a key not properly programmed to the vehicle. Try a different key. Also, are you 100% certain the battery you installed is strong and fully charged -- able to handle a load?
