Hi i was wondering if anyone knows how to reprogram keyless remote for my 2002 ford explorer.

Do you have the owner's manual for the Explorer? Often the instructions are printed in there if that's something the owner can do. Some of the newer vehicles require programming to be performed by a dealer or locksmith with the appropriate tools.

If you don't have the owner's manual, try searching the forum, I'm sure it's been posted before.
