i've cleaned up crank noses and reinstalled a new crank pulley countless times. the crank pulley does *not* "need" a wooddruff key to stay in place. 3 foot pipe over the socket wrench and it's not going anywhere. most people simply don't install them tight enough or the engine isn't properly held in place so you're actually getting full torque onto the bolt.
i've installed a bunch without a key because they're old, not worth a debacle of a repair and given the vehicle/person who owned it, it didn't matter...or some other reason. works %100 of the tim with enough torque.
that being said - you should be able to grind/drill out the key as well. and actually once you get past the initial few millimeters of damage the sprocket may/should slide off and give you enough material to install a new key maybe?
air grinder or dremel tool to cut the sprockets off and then deal with the keyway?

Cut the bad section of the key away - you do not want to drag the sprocket across the messed up key. Then pull off the sprocket - and order a new key from the dealer.

Yes, you're on the right path now.
Props Gary...still pondering cutting the bent part of the key out of the way. But, you said you've torqued em down b 4 w/o a W key?.....I can still fit the pulley on the crank nose with the old key still in.....what is the max ft. lbs it will take?...ideas?
1. just cut/grind/drill the bent part out of the way - the first few millimeters probably. then it'll all come off.
2. or just leave it in place and make it flush so the crank pulley bolts back in place properly. tighten it really good and it's not going anywhere. i've done it countless times - i never use a torque wrench - i just get a socket on there and y 3 foot pipe and give it some good stank, so whatever that works out too!
sounds to me you need to skip all the other talk and just tighten it down as i've suggested - sounds like i'd have it "fixed" in about 4 minutes.
