Consumer Information for the Garage Door Opener Control?

Answer 1

Garage door opener controls are devices made to open garage doors at a certain distance away from the doors. Most openers work by transmitting radio signals to the opener. Each control is unique to its associated automatic garage door.

Different Types of Garage Door Openers

A garage door opener's remote control is essential to operating the door. In most cases, the remote has one or more buttons. However, some controllers come in the form of a keypad. Even though keypads work differently from remote controls, they both transmit the same type of signal. However, garage door keypads require the user to input a certain number combination in order to send a signal that allows the door to be opened.

Multiple-Button Remotes

Some types of garage door remotes contain multiple buttons. These controllers are useful for garages with several doors, such as the ever-popular two-door garage. The buttons on these remotes are programmed to transmit a different signal to each door opener.

Garage door opener control buttons work similar to toggle switches. Each button controls the upward and downward movement of the door. Some three-door garages come with three-button controls. These remote controls work no different than their one-button and two-button counterparts.

The "Code Grabbing" Issue

One of the main concerns consumers have about garage door openers revolves around security. In some cases, a crafty person can intercept the signal sent to a garage door and use the signal to open the door. This criminal act is commonly referred to as "code grabbing." Those who do not know how to code grab can go from garage to garage with a single remote until they find a garage that matches their remote control's frequency. This leaves garage owner's homes open to trespassing and burglary.

There are several ways to counteract this problem. Most newer garage door controllers transmit a specific code along with a radio signal. Both the signal and code have to match before the door opener can be activated. Other remotes also have a "roaming code." With a roaming code, countless number combinations can be generated to prevent code grabbing.
