trying to program a ford keyless remote

Hi i am trying to program my keyless remote for my ford 2002 e-450 van. The numbers on the remote is FCC ID: GOH-3BFM2497, CAN: 1409 102 688. i have one remote that is programmed and one that is not. The keyless system is a ford installed unit.
Can anyone help.

Thanks
Mike

This keyless system is a ford aftermarket system. It was installed by a ford dealership as i was told. Someone told me it was a code alarm system or something like that. Can anyone help me figure out how to program my remote with this system?

thanks

ok is it a key fob that says ford on it ? if so ok you can check with your local ford service dept they should be able to help, its its a code alarm system it will say code alarm on the key fob, ok the old way (early late 90's) thats may still work, get in the vehicle and close all the doors and lock the doors, put the key in turn it to run the off run then off 5 times the doors should then unlock, use your working key fob to lock the doors they should then unlock by them selves, then unlock them with the new key fob, open the door and you are all set, that works with most fords
