In order to replace the card you will need to remove the keyboard. You can do this using this guide.

CAUTION: Before you begin any of the following procedures, turn off the laptop , unplug the power adapter and remove the battery. Note that computer parts are very sensitive to static electricity so ground yourself before touching anything inside you computer by using grounding strap or touch a metal faucet  pipe.
