I did that several times. soon after I tried starting it and now it doesnt even attemp to start, no clicking, no nothing. Now the security light is on on the dash when I have the ignition on. Any idea what this could be? Thank You1

HI there, I am Cam. Can I get your first name? "

What is the battery condition? Did you try a boost or charging it?
