hornet 553t alarm not responding

I have a hornet model 553t alarm/door lock/remote start in my truck. All of a sudden, none of my remote functions work. I can't start, lock or unlock the vehicle. I tried to reprogram the remote thinking that it lost its program. Typically, I have pressed the program button, released, press and hold until it chirps. When I tried this again, I couldn't get into the program mode. I couldn't get the system to acknowledge what I was doing with a chirp.

Is there any thing I can try to get this system to respond?

Vehicle is a 2001 Dodge Dakota Quad Cab. In case it helps.
