Chrysler Voyager SE year 2000 (Key Fob Programming) HELP?

When I purchased my car it came with one key and one fob.





I can get a replacement key for my car inc progamming for £65 + vat.





However I have accquired a second fob which has the same part number on it as my original fob and the batteries in it seem to be working OK.





Can anyone help or give me instructions on how to programme my spare fob, so that it works in the same way as my original fob.
