If a new battry or jump start does not work, it definitely is not the alternator, at least for now.
It could be :
2. Security system.
3. Ignition switch.
Start by getting the starter circuit checked/tested. Unplug the starter relay in underhood fuse box.
Test for battery voltage at terminal #5. If voltage is available, use a fused jumper to connect with terminal # 3 and note if starter cranks.
