Every year I put Christmas lights on the house. I can control them with a remote button. But every time I turn the lights on or off my neighbor's doorbell rings. Occasionally I mess with him. Especially funny when he's standing at the door and his doorbell rings. He has yet to figure it out.

 

Is this the remote control for your doors, as it's on the 315Mhz band and uses dip switches to set the programming.?

This is the remote that the system uses. It has 10 dip switches to set the frequency.

Then try changing frequency...
