Fabe not working with car?

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.

It can be the receiver or body module or something else in the car
Go to a locksmith. Change the battery in the fob.
If you don't have a backup fob, you may be able to get one at a locksmith.
The can often get the code from one fob and enter into another new one.
Maybe it will solve the problem. At worst you would have a backup key fob.
Some locksmiths are working on remotes and I'll bet they are cheaper than a dealer.

If it is not a battery, then it is a dealer item. BTW it is a fob, not fabe.

Update: Fob* not fabe. Tried changing the batteries and it still wouldn't work. I had a backup fob too, but that one didn't work either. I forgot to mention the year. It's a 2015. I'll contact the dealer first thing tomorrow, but I'm afraid they are going to say they need to see it in person… That then will require a tow.
