If you're going to do it, just replace it with the old switch. With the cost of the new switch, lock and programing you can replace the old switch 5-6 times.

They carry the part at AutoZone for $32 and it's listed under the Boxster.

I found it easier to remove the left front vent and replace it from there. Jeweler's screwdrivers did it from that point since the vent tubing in the way is what requires the stubby screwdriver. You just need a small torx screwdriver (15?) to remove the headlight switch and vent covers if you go in from there.
