I know they say use the proper tool but I never have... just be careful and use a very small tipped flat screw driver and pry adequately in one of the two corners that can be accessed. Try and support the corner as best you can or even place a pencil or similair width at the corner for leverage. Just gently but progressively work it up. You can alternative between the two corners but usually this makes the other corner dip downwards again.
Do remember to note the orientation of it though...
I just did this the other night actually...
Once I used a bit of rigid wire folded in half with the very ends crimped up by pliers, I've always meant to get the right tool just never bothered too, probably because I've never ordered a chip by itself...
Be aware of static electricity... but over the last 25 years simply ensuring I touch the inside casing of my computer I've never fried a chip yet...
