Hi, I have a 2009 Toyota RAV4 that I purchased not too long ago (about two years) from a dealership. It recently was having issues starting. I checked to see what my OBD2 scanner could bring up, and it gave me a single code for B2799 - "Engine Immobilizer Malfunction". This seems likely since the fuel pump will not prime when turning the key, and it will not start. I have two keys, but both of their remote starts have stopped working. The battery is brand new (not sure if that matters). I searched on these forums and it seems that a few other people have had similar problems, but I have not seen a solution. Is this something I can fix myself, or should I search for professional repair? Thanks.
