Stereo & Electronics - **Where can I find keeper rings for exterior door locks?

Has this happened to anyone else? :confused: Those little keeper rings that sit behind the exterior door locks that hold the key hole in place have disappeared on my car. Where can I find these and how much do they cost. As it is my exterior door locks sit very loosely and will even come part way out if I turn them a certain way. I'm not too comfortable with my camaro sitting unlocked :eek2: Any replies are awesomely appreciated.

You can buy these at Auto Zone, or almost any automotive store, even GM, they are very cheap. They are just a C-clip and slide right in. U can actually change the whole lock cylinder and get a new key (both doors) for less than $20.
