Do you have any other cards you can use?
Err 02 simply means there is an error communicating with the memory card. It could indicate a problem with the card... but you can get the same error if it's the camera. You would want to test using a different card.
Also... if you remove the card and look inside the card slot, do you see any obvious debris in the slot which should not be there? Or any signs of damage?
That's a fairly old camera, so it may well be the camera.
HOWEVER... even if it is the camera, do not discard it. Your broken camera is actually worth a substantial discount on a replacement. Contact Canon and inquire about the Canon loyalty program. They allow you to trade in your old broken camera for a newer model (which may be a refurb) and a substantial discount off what it would cost to buy a new one. The models available in the program change from time to time so you have to contact them to find out what the current offers are.
Lenses for your existing camaer will work with new models (unless you were to buy a "full frame" camera -- in which case only the "EF" lenses would be compatible). For anything else, (all Rebel bodies, the midrange 60D and 70D bodies, as well as the 7D) all your current EOS lenses would be compatible.
