I need instructions on how to program keyless remotes taken from my old ford excursion and i'm wanting to use them on my Isuzu rodeo? Is this possible?? And does anyone have the instructions or where to get them.. Instead of the dealer!!

No it is not possible. You need isuzu ones. You can purchase them on ebay.

Ford and Isuzu use entirely different remotes and receivers.

For the 98-04 model Isuzus, you will need the remote with FCC: HYQ1512R.
