Problem with key fob and theft system
 

Hi, everyone, I’m new here, and I have a problem with my Malibu 2013, I can start my car with the remote, but as soon as I get inside the vehicle and put the key in the key cylinder and try to turn it on completely, it shuts off and activate the anti-theft system, did anyone know why it’s doing this? Or have any idea how to make it work?, thank you everyone
