i've recently changed out my battery on the transmitter and it stopped working... i tried putting a newer battery and it still doesnt work... everytime i try to autostart, lock/unlock the car, it shows up on the transmitter as a no page. i dont get whats going on here... the transmitter receives a signal from the car every 5 secs but i cant transmit anything to the vehicle. i've tried disconnecting the battery and reconnecting it but it still doesnt work.. if you have any suggestions please dont hold back.. i need help!!!! thank you
