How much do Remotes usually run...
and where could I get one...
You can get them on ebay, from GM parts direct, from a local dealer, from junk yards. Many places. You should expect to pay anywhere from a couple dollars at a junk yard to $80 at a dealer. Ebay you can get them for around $15 or GM parts direct has them for about $45.
