2001 L series keyless remote programming

Does anyone have the instructions on how to program a new keyless remote for a 2001 L Series? I just purchased the car for my daughter, and it had no remotes. I have a couple of new ones, but can't seem to find the information or instructions on how to program them to work with the car. :banghead:

From what I understand, you need to program the transmitter through the TECH II machine, so that it is programmed to the BCM in your car. Has to be taken to a dealer for that.
