Fabe not working with car?

Hello. I have a new Honda Accord and the fabe (remote control) is not working for it. The light on the remote blinks when I press a button, but nothing with the car works. It doesn't unlock, lock, pop the trunk, use the alarm when I use it. So, it probably isn't the batteries. I used the actual key to get in the car to see if the push button start would work with the fabe. It did not as expected. Taking it to the dealer is one of the last things I want to do because 1. I'm on a tight budget and can't pay a car company to check it up. And 2. It's winter and I do not want to get my car dirty or in the cold. Can anyone help? Is there a way to sync the fabe with the car or something? It used to work when I first bought it (in July), but maybe since I've barely touched it since (it only has 177 miles on it) that the fabes need resynchronized or something.
