Will changing a battery reset all codes?

I'm getting some coding done tomorrow but I also need a new battery as I'm running 6 years now on my still original one.

What would cause all coding to be lost btw?

Change your battery first, no better time than now to get a fresh battery

No, it should not cause coding to be lost, if it did, you'd have to completely recode your car every time the battery died or was replaced. =)

no it does not, I replaced my battery and did not lose any coding.

My battery also died last night because I left angel eyes on again and I did not lose any coding.
