My garage door has opened twice in the last 2 weeks during the night. Is someone driving by and opening it "accidentally"? How do I keep this from happening?
If you have an older style garage door remote, before they used rolling codes, you could very easily have some people driving by activating it accidentally. I had a similar problem, so I ended up unplugging the remote control portion of it, so the wall mount switch still works, and the whole unit is going to be replaced soon anyways (electric eye sensor, etc).
