A clicker garage door opener is a very useful device, intended to help you open your garage door while being meters away from it, just by pressing a button. In heavy rain conditions, getting out of the car and manually opening the garage door can be very stressing. The other advantages – no wires that need to be installed and no keys.
The clicker garage door opener consists of two parts: a remote and a receiver. It is a very simple device that transmits signals to the receiver installed in your garage, which controls the opener mechanism. It is very similar to the clicker car door opener. The technology advanced a lot lately, since World War 2, when it was first used to detonate remote bombs, and after that, it became common in lots of domains.
The clicker garage door opener was used even when people start building the first garage doors, being a pioneer in the wireless technology – the remote. But that time’s technology’s disadvantage was that the remotes were low in power but still powerful enough to interfere with the surrounding receivers, so that one could open their neighbours’ garage doors. The next step in the wireless technology intended to solve this interference problem. The solution they found was to introduce a digital code intended to focus the signal on a single receiver. These codes were not intended for security purposes, as the maximum number of codes used for a single remote were 256.
The next step in clicker garage door opener development dealt with the frequency problem, ranging from 300-400 MHz and started using the rolling technology. This is the stage when security appeared as an issue. A burglar can record a code and use it to open a garage door, but the rolling technology produces a huge number of codes for the receiver that are constantly changing due to an encoder that generates new ones. This way, the remote and the receiver work with a software technology that create a new code, keeping it in memory so as to use it for the next operation. Once the receiver finds a code that matches with the saved one, it automatically opens the garage door.
What you should do with the clicker garage door opener after you bought it is to program it by entering a secret code you need to remember. It should not be a sequence of numbers easy to guess, such as 1234 or 5432, choose out of sequence numbers and keep the code somewhere safe.
When buying a clicker garage door opener, the best choice is to acquire a universal clicker that allows you to change the code by yourself without having to send e-mails or call the provider or the help desk. The best clicker garage door opener have also codes that match with the majority of vendors. Consequently, if you happen to lose the clicker, you can always replace it, as it’s not irreplaceable.
