Ingition Switch problem
no, you just need to ONLY replace the cylinder and if the new key has a chip in it get a copy made and use that one with your old master key held next to it to start the car.
How do I go about replacing the fuel door/trunk
First off obtain the shop manual for your model. It will give you steps and photos on how to fix almost anything on your vehicle.

First things I would look at is,did they put 10w30 oil in and not 5w20 or 0w20,it makes a difference in mileage (if they run out of the correct viscosity oil they WILL put in what they have).
Did the service include a spark plug change?Is the spark plug gap correct?
Did they do a brake service?Is a brake dragging,a little to tight?Did they clean the throttle body?Maybe the engine was running a little lean before and now is at the proper fuel mixture,with less MPGs but running clean at the exhaust.
Weather conditions?Head winds and colder temps reduce MPG.
