Originally garage door openers used an actuator in order to open and close the door. This actuator was controlled by a very simple remote. The remote consisted of a transmitter. On the actuator, there was a receiver that was associated with the transmitter. There was a major problem with this type of opener though, security. The transmitter had no specific code attached to it. Because of this, anyone with a transmitter could open or close the garage door. This could even happen when they were trying to open their own.
The next type of garage door openers had dip switches. These dip switches came with 256 different combinations attached to it. This was able to stop your neighbor from accidentally opening your garage door. The only problem is that someone could easily record the radio frequency of your garage door and use the same frequency at a later date. This would enable the person to open or close your residential garage door without having the actual remote with them.
Today, all of these complications have been overcome. There is no longer a major security issue when it comes to garage door openers. Most openers now have something called a rolling frequency or a hopping code technology. This means that after each use of the remote, the opener changes the frequency. This makes it very difficult for someone to find out the frequency it happens to be on at the specific moment. Most likely, your garage door opener and remote are already connected to a rolling frequency. If it is not, you can easily purchase one at any hardware store in your area.
Now that you know how Wichita garage door openers evolved, let us look at the types of openers that are now available. There are now remotes that attach to the sun visor in your car, on your key chain, or even a keypad on the threshold of your garage door. All of these types of openers are great and each provides its own type of security. Personally, we suggest the openers that attach to your keychain. They are very small, but still easy to find in your purse. The reason we suggest this type is because someone could find out the code to your keypad which would allow an intruder to enter, or someone could notice the remote on your visor and simply break into your car and steal it.
