How Garage Door Remotes Work Tip Top Garage Doors is a local Charlotte garage door repair service provider. Garage door remotes come with automatic openers and they enable one to open or close the door while still in the car. The old generation remotes use switches while the modern ones use rolling code technology that changes the code after every use for security purposes. Once the remote is pressed, it sends a signal to the opener for the door to open or close. A remote may break, get lost, or become faulty. This calls for simple programming, repair, or replacement whereby you can involve a technician or use DIY tips.
