The reason it looks plain is because they needed to make if fit the "fobgina" under the steering column when the battery is low. There's a slot under the window-wiper stock that you can put the fob in to operate the car if the fob's battery gets too low for the transceiver to pick it up. That's really the only reason the fob is shaped like that.

Nissan/Infiniti does the same thing.

Theres a key inside the key fob

The key inside the fob is used to open the hatch so the doors can be opened if the car battery goes kaput, and not to start the car. You will need a jump if the car battery dies.

Yes, I know. But it doesn't start the car.


Oh! Just realized this is a thread about dead car battery, not fob battery.
