Called several times and left messages and no one from the office returned my calls. When a tech finally answered, he responded and was great! I would not recommend trying to work with this office.

Garage-Door Openers: Signaling Security

Learn a little about the technology inside the little remote in your car with Groupon’s examination of garage-door openers.

In 2012, garage doors throughout southeastern Connecticut mysteriously seized up. The culprit? A military submarine base. 

Annoying as it may have been, there was nothing sinister behind this pattern. Rather, it was simply a side effect of the way all remote-entry garage-door systems are designed. Each time you open or close a garage door, the remote and the receiver inside have a brief conversation in code—a conversation that happens to be conducted via radio signals over the airwaves. The unfortunate homeowners in Connecticut eventually learned that the signal emitted from the submarine base’s radio-communication system shared a frequency with their garage-door systems, and the more powerful military signal drowned out the information their remotes were trying to transmit.

The codes transmitted by garage-door remotes have gotten far more complex over time. As early as the 1960s, burglars learned to use radio scanners or “code grabbers” to pick up the code when the homeowner used it to open the door; they could then re-transmit the code to gain entry themselves. In response, most remotes today use rolling codes that can generate billions of combinations. 

This is possible because each time a message is sent between remote and receiver, each part of the system also selects and stores a new code. Those codes will always be in sync because each has been programmed with the same pseudo-random number generator—that is, a formula that produces a sequence of numbers that would appear random to anyone not possessing the formula. (Beware, however: it is possible to desynchronize the system by pressing the remote button out of range of the opener more times than the system’s built-in tolerance for error will permit.) Once this is done, the remote and receiver are ready to kick the system’s motor into gear and help you begin or end another day on the road.
