Remote Start Stopped Working?

My remote start was one of my favorite features especially in the winter, but all of a sudden it just stopped working. You can use the same remote start button to open the trunk so I don't think it's the remote (Tried both of my remotes) any ideas on what to do or how to fix it? Thanks a ton!

I found out the remote starter is an Audiovox Pursuit Series trasmitter. Also, one possible cause of the problem could be the storm we had a few weeks back, some water leaked into the car and flooded the floor. All the other functions on the remote work fine though.

Double check the safety switch. Most people trip those under dash and don't know it.
