I am surprised that nobody has mentioned the (to me) obvious solution, which has worked for me.  You buy a 2032 holder.  Put the cell in it and you have solderable pins.  Replacement is easy.  They only cost a few cents on ebay.  Search 2032 holder.
Ummmm… somebody did, several messages before yours:

... I'm thinking I can solder wires to an existing 2032.

To avoid possible damage from overheating, it would be better to solder the wires to a button cell holder, and then insert your existing CR2032.

i soldered one a while back, but I left it in the freezer first for a while, sanded the area to be soldered and cleaned it with alcohol and fluxed it. the housing that its in could take a bomb, and its been OK for like 3 months (2430)

you need to solder it in as little time as possible with as small a joint as possible to keep it from over heating
