Hi again Chris. Two things are needed to time up the bottom of the engine ...a crankshaft pulley that hasn't slipped and a woodruff key in place, so I would have though the key was in place before the balancer shat itself. (You were lucky it didn't take out the cam belt!). The reason I say that is even if the timing is out a tiny bit the engine check light will likely come on, at least intermittently. Ask me how I know 
!!
If you can't locate the key it's Peugeot number is 6979.06. I doubt you'll be able to locate a new one but maybe a scrappy will have one. I have a feeling the key will be the same on the HDi's and the GTi-6's but I haven't actually checked that. I'll try & find some time to check on servicebox later.
Attached are the parts diagrams for the pulley / crankshaft etc if that's any help.
Cheers,
James
Thinking about it some more I don't think the woodruff key could fall out with the crank sprocket still in place. Only a very small piece of it engages with the crank pully (maybe a couple of mm). Are you sure the sprocket is fully seated?
