Hi,
First, here is a link that explains how to reprogram a keyless remove (fob):

However, according to my manual, to program a fob requires a scan tool that can communicate with the vehicle's remote keyless entry system (RKE). Here are the directions I have:
_______________________
2002 Saturn L200 L4-2.2L VIN F
Transmitter Programming
Vehicle Accessories and Optional Equipment Antitheft and Alarm Systems Keyless Entry Keyless Entry Transmitter Service and Repair Procedures Transmitter Programming
TRANSMITTER PROGRAMMING
Each transmitter is coded to prevent another transmitter from activating the RKE functions on another Saturn, as long as that particular transmitter has not been specifically programmed to that Saturn.
A transmitter can be programmed to as many different Saturn's as a customer owns, as long as they have the power door lock option. Each Saturn can be programmed with up to four transmitters.
To program transmitters use the Tech 2 BCM special functions, Program Key Fobs.
To program customer options refer to "RKE Customer Programmable Content Theft Programming".
