Can I find a CD Key from a computer game already fully installed?

I have a copy of The Sims 2 installed on my main computer, and I'd like to install it on a newer computer I just got. (Legit deal. I own the game and both computers.) However, since the initial install I've lost the CD Key. Is there any way I can 'find it' using the existing install I already have?Can I find a CD Key from a computer game already fully installed?
The same thing happened to me a couple years back, except it was on the Sims and several of the expansion packs. Oops! I called their tech support and they were very nice about helping me get registration codes. I think I had to have the original CDs to hand, but I'm not sure.Can I find a CD Key from a computer game already fully installed?

If you registered the product I bet you could call EA and get it from them.
