Programming a common remote cloning button

This is a classic cloning button intended for low security fixed code remote controls. It will not work with vehicle code-hopping remotes and must also be the same frequency as the remote you are cloning.

To use it, click the button four times, holding the button continuously after the fourth press. After several seconds the remote will start flashing its LED and then a few seconds later it will go static.
At that point release the button, and then pair your existing remote by holding them next to each other and pressing and holding both remote's buttons at the same time.
The cloning button will blink randomly and then go static. At that point it should now operate as the original remote.
