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
Most of the time all you need to do is replace the battery. If it doesn't work after that, you will need to take it to a dealer.
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.
It was optional.
more info. Well i have a remote from my old 96 grand am. Now i just bought a different one and it didnt come with the remote. Can i program the old one to work with the new one? Its pretty much the same exact car minus a couple things.
Insert something thin and hard, such as a pocket knife blade, in between the remote halves. After this, simply pull the halves apart and replace the old battery with the new. Snap the remote back together.
Possible weak battery in the remote.
