One of the great benefits of modern garage door technology is the convenience of garage remote control operation. Garage door remotes mean you no longer have to get out of your car to open the door; however, if your remote is lost, broken, or stolen, you may need to know how to program a replacement garage door remote.

How Do Garage Door Remotes Work?

Garage door remotes work by sending a coded signal via radio frequency to the garage door motor. If this code matches that of the motor, it will begin to raise or lower the garage door. Older devices utilise a single coded switch, whereas newer systems use a rolling code that changes each time the remote is used, increasing the security of the garage door by offering billions of unique combinations.

NB: If your garage door remote has stopped working or only works intermittently – check the battery first. A weakened battery may not have the power necessary to transmit the signal to the garage door motor. 

Can You Replace a Garage Door Remote?

When choosing a replacement garage door remote, the most full-proof method is to purchase one that matches the model and manufacturer of the garage door motor. This should ensure that the radio frequency and code switch of the garage door remote match the requirements of the motor, as these are not standard across brands.

If this is not possible, you could purchase a cheaper, generic garage door remote replacement that will work for a number of motors, such as the Boss/Guardian 2 button unit. This garage door remote can operate Boss, Guardian, Modern, Steel-Line and Centurion brand motors, but be aware that not all garage door remotes are interchangeable even if the frequency is the same.

Universal garage door remotes are also available, but check to make sure that your radio frequency is supported before you purchase a replacement garage door remote. This can usually be found on your existing garage door remote or motor. For example; “433 MHz”.

When selecting a replacement garage door remote, you will also need to ensure that it is suitable for single or rolling code openers. If you are in doubt about what code system your garage door opener uses, consult the operation manual or contact your local garage door company.
