Try to program the remote control first. If you still can not get it to work you can then try clearing the circuit board first. If you clear the circuit board you will need to reprogram both remotes and phone if bluetooth. Depending on the age of your circuit board your lights might be different.
Push and hold the button on the circuit board until the red light goes off. This takes about 10 seconds.
Now push the button once. The light will now stay red. Push any button on the remote and the red light will blink 3 times and go off. This means the remote is now paired with the motor. Now grab the other remote, press the button on the circuit board so light comes on and then press any button on the other remote. Light will flash and then go out. Both remotes have now been paired. (the remotes take about 10 seconds to work after they are first paired with the board.)
