I found this link while trying to find some information on how to program my 1998 caravan. http://dodgeram.info/tsb/2002/08-007-02.htm It gives instructions for the 2001, and 2002 caravan and should work on yours. (It also shows for several other modela as well) If anybody has any information on how to program a keyless remote for a 1998 caravan i would appreciate it if you could help me out, as at this time i am still trying to figure out how to do mine, thanks.

The site above gives instructions if you have a working remote, but what if you dont have a remote that works at all???
