I was driving on high -way and car just shut off on me...

What is your question?

I started right back up no problem,,car didn't over heat nothing ,no lights came on the dash nothing. I thought because I have a lot of keys on my key chain maybe., (If my other keys hit the ALARM PAD ) would that shut my car off on me ??? Also this is the 1st time it happen to me. I only have 38,798 miles on car ...please help me
