Hi,
I am having a problem with the two remote controls for my garage door opener. Neither one will open the door I have tried new batteries in both of them to no avail. I have also tried to reprogram them both with out any luck. The door opens ok using the multi function keypad.I have had the opener for about three years and had no problems until now.Can anybody please help with this problem.

There could be 2 x reasons why this has happened
Either interference from an out side source is blocking your signals or the radio reciever in the units has gone faulty
This i very had to identify without changing the circuit board or listening on 433mhz with a radio scanner
Interference can be caused by any new electrical equipment in the building , Tempary Traffic Lights , Radio masts , Police , Fire , Ambulance stations etc etc
