Its funny you posted this, I'm working on this right now.
I just replaced the battery and the light works and nothing happens. I looked in the manual, it says to "turn the keys to the ACC spot in the ignition then hit either the lock or unlock button on the remote". You should see the outside indicator lights flash when it's programed. Well I tried it 10 times and I still can't get it to work.
Just call the shop and they want 95 bucks for new remote and 60 bucks to program it, I yelled at the guy..lol.
Let me know if this works for you, look in the manual, maybe I'm doing something wrong but seems straight forward.
