Almost all garage door systems include a garage door opener; the opener is the mechanism that controls the garage door and ensures its security. In a garage, garage door openers are motorized, complex devices connected to switches on the wall or controlled wirelessly.

Chain drive garage door openers, belt drive garage door openers, and screw drive garage door openers are the three most common types. Garage door openers use a motor that moves a trolley on a track back and forth, which enables their doors to open and close. The names refer to the different types of pulleys contained in the motor. The track is attached to a power unit.

Garage door openers also have quick-release features that can be used in emergency situations or during power outages, in addition to signal sensors for connecting to access devices and receivers. Meanwhile, a complicated assembly is powered by a power unit.
