Doing it the MacGyver way I take a piece of string and make a key pulling rig by tying a multi-loop knot.
Since this doesn't need any fancy knot, you can actually do this by tying an
overhand loop, then pulling one of the ends through the loop and back up. You should now have 2 loops.
Once you got a string with two loops in it, take two popsicle sticks. Place one loop in the gap between backspace and the enter key and push it down with the popsicle stick. Pull the loop to the bottom edge of the keyboard so it will hook under the key and make sure it can't come back up the gap by pushing the stick to the bottom.
Take the second stick and push the second loop between the enter and right shift. Pull the loop to the top edge and keep it in place with the stick.
Now the rig should be stuck under the key. Pull the ends up whilst making a circular motion to wiggle the stabilizer and key stems.
EDIT: This works great on spacebars too, even those with really tough vanilla G80-3000 keycaps - forget about two wire key pullers when you can do it cheap and sound!
