i just got in a carbon fiber trunk lid for my car, any recommendations on how to go about cutting out the key hole? all i can find online is put tape down and drill really slow with a diamond bit.

Dremel, painter's tape, and respirator. Measure twice, cut once.

Carbide grit burrs (they look like a cylinder made of solid sandpaper, but not a sanding roll) work really well, you can get them at Lowes for Dremel tools. Anything with cutting edges like a regular cutter or drill bit will run the risk of splintering the fiber bundles. You can make a pilot hole carefully with something else, but enlarge it with a carbide grit burr.

Jay's all worried about his health, real men don't wear a respirator. Black lung is the way to go..

It cuts and drills just like fiberglass. Put tape down to keep the finished edge from splintering. Also use a drill or hole saw that has as high a tooth count as you can find.

Go to Lowes..

Quick google search, this is what they look like:

Ya, I felt like I smoked a pack of cigs all at once. Carbon dust = no bueno.

It's the epoxy that's the killer, carbon is pretty inert. You can get something similar to asbestosis from the short strand carbon fibers though, it's not that fun either.
