Question: Security light on car wont start unless jumped off it shuts itself off no warng if I let off gas pe

I purchased a used 2000 nissan altima almost 2 weeks ago. The only issues that I could tell was for some reason for different reasons like ideling or even driving it would sometimes hesitate and then all sudden shoot off. I just started a new job Monday and I have to drive through a electronic gate to enter the factory I work at as well as I am required to use and carry a electronic badge that allows each room to unlock I use it approx 20 times a shift. Nothing went wrong Monday or tuesday but wensday I made it to work with no issues but after my shift I went to start it and got nothing. I had it jumpstarted but I noticed the SECURITY light was now on. I turned the defroster on and it shut off. I jumped it again and still the security light never went off. I was so scared it would shut off the that I never let off the gas pedal the entire 20 miles home. Today I have had to jump-start it everytime I went somewhere and it even shut itself off in the middle of the street!!! Completely dead! I have dug and searched to see what could be causing this and the only thing I can see is my car key has the bottom tip of one sides black coating missing I can see (an d touch) the blue chip that is for the security system. The manual states that a keys chip if came in contact with exp another device with chip or even a toll booth. Like I said I drive through a gate to enter use a electronic card all night and even walking through a metal detector. Is it possible to have caused my car to not start on its own at all if it somehow somthing interfered with the chip in NY key and activate the security system? Is there a way to bypass the security system and completely reset it?
