ahh thats gay someone did that to one of my zs once and broke a plastic retainer clip so the whole locking cylinder was inoperable. I had to buy a new one and install it.
I suggest buying a new one and installing it if it stops working. Its around ~$200ish from the dealership for a new locking cylinder and ~$30 to get it badly keyed to your existing keys so it doesn't work. I wasn't happy. Its no fun carrying around 2 keys.
Its not particularly hard. ~45 minutes or twice that if you suck at cars.
