Thanks for choosing FixYa and welcome to the site. The alarm is what is causing the vehicle to not start. You may be able to pull the fuse for the alarm to get it started. There should be a code that can be entered to reset the alarm. Check your owner manual. If not, you may have to contact the dealership to get the code to reset the alarm. Try not to use your key fob to unlock the doors as this will only keep the alarm on. I doubt anything else is wrong with the vehicle. The security alarm will kill the vehicle and cause this. If the fuse doesn't work, you need that code. You may be able to take off the hot side battery post for a few minutes and reset everything. Once you do, don't use the key fob for nothing.
