I really neen some advice. I've got a 1998 Jeep Wrangler TJ 4.0. I lost my keys and while taking it in to have a key coded, Jeep's own mechanic blew my computer box and was told that they don't manufacture the computer box or body controllers anymore. My Jeep has turned into a big red paperweight. Can someone with more knowledge and experience than me please comment or help?
