Most modern cars unlock their doors with a simple button press on the key fob, which sends a coded radio signal to the vehicle's receiver. If the fob is dead or lost, you can often use the physical metal key blade hidden inside the fob to manually open the driver's door. Some models also allow unlocking via a keypad on the door handle or through a smartphone app.
