Did you try getting a jump on dead car day 3? If so what happened? As suggested before, this is probably a starter problem but it could also be ignition switch or even a fuse. Two other possibilities are wiring issues (corrosion on battery terminal, corrosion between battery cable wiring and battery cable terminal, bad ground, etc) or a parasitic drain (something electrical that does not shut off when the car is shut off; light in trunk or glove box, door ajar warning light, etc over several hours these can drain a battery).
Replacing the starter is straight forward and no need to get under the car (can all be done from the engine bay). Basically you remove air filter housing/MAF, unbolt starter and slid it out towards you over the transmission, unbolt/disconnect the wires. Installation is the reverse of the removal. Autozone will test it for you for free because they want to sell you one. There was a recent thread about changing the starter titled ”changing out starter” Do a search.
