HOPE THIS IS IT... Sit inside the vehicle with all the doors closed. Place ignition in the OFF position. Open the driver's door. Leave Open. Move the mechanical door lever to the LOCK position. Turn the ignition to the RUN position. Aim the transmitter at the Keyless Entry receiver and press Lock button. Hold for five seconds until the door locks cycle. Turn ignition OFF within 20 seconds.
the dealer does it with a scan tool
You have to program it with a DRB (Scan tool).
I had the same problem. Google "keyless entry remote 2003 Jeep Grand Cherokee".
dealer has to do it with factory scan tool
it has to be done by the dealer. =(
Possible weak battery in the remote.
I had to replace a keyless remote for my 2001 dakota. I found one off od E-bay then I had to program it using the programing sequence in the owners manual. It was really simple. I only paid something like ten buck for the remote and have had no problems.

how do you program a keyless entry remote to a 2000 Pontiac grandprix programyourremote.com (program your remote.com)
go to http://www.programyourremote.com/ they have programs for many makes and models
I am trying to find out how to do the reprogramming, but haven't found out how, but did find out that from 1999- 2004 the door lock fobs are interchangeable. You may need to take to Jeep dealer to actually get it programmed, but at least you won't have to buy a new fob.
Try the mirror control.
