E.T. Systems seems to have quickly taken over the garage door and gate automation market in Cape Town - every second person has one of those ugly, blue remotes - some with up to six buttons on them - attached to their key rings.

I recently had 2 of my remotes fail within the space  of a month and was off to E.T. Systems to acquire a new one (at a whopping R125 mind you!)

Here’s the simple procedure to sync your new remote to your E.T. Systems garage door:

The E.T. Systems remotes work by implementing some sort of patented rolling code transmitted by the remote and identified by the receiver. Without digging into details, this rolling code necessitates syncing your remote to your garage door.

To start, pop open the plastic cover of your garage door. Next, search for 3 pins labeled “BT LT” (bottom right of the circuit board in this picture):

The idea is to short the pin on the “BT” side with the middle pin - press the button on the remote that you wish to use to open the garage door and at the same time use something metal to “short” the pin labeled “BT” and the middle pin. You should hear a beeping sound which indicates that the operation was successful.
