Will not start

But it will not unlock or lock doors should I try a new fob?

Sorry lost first part of reply. Tried security reset, no luck. Tried activating fob not sure if it is good, replaced batteries. We just bought the vehicle. I am confused it said when panic. Button was held it would shut off security. Light which it did but it will not lock or unlock doors. Should I get a new fob or does that have any effect on it? It will still fire and start but immediately shuts off. I have searched the web purchased book everything for the past week and nothing works. My husband is not mechanically illiterate he has always worked on our cars and everybody else's, but he is just about ready to burn this vehicle to the ground. Any other ideas? Thank you

If this was not working would it cause vehicle to not start? Is there a fuse or module that could be blown? Would it be smart or not to bypass security to see if that would possibly work and what are the chances of crank shaft sense if that was out it would not crank would it? Thanks again

Just went through trouble shooting video. Up to testing coil for spark. All is good so far. Key remote is no good do we have to have one?
