Garage door installation generally comes with the placement of the garage door opener unit. This means your garage door remote control will be programmed so that you will be the only one to open the doors even if your neighbor has the same garage door clicker. Garage door remotes are limited to about 315 Mhz which means that only the set codes, at a set distance, can open and unlock the garage doors. A-1 garage does a very great job ours.
