Update – The ET website has come a long way in providing information and brochures since this blog was written, so be sure to check the ET website for information specific to your garage door or gate. Here is a copy of a comment made by someone from ET systems on this blog:
Hi Folks, in future can I suggest you try our direct technical support facility on our webpage for ET Systems product support.
Neil, while your method described here will work, it will not work to well and the possibility of learning a neighbour’s remote transmitter before you have pressed your new remote button is very likely. Rather follow the instructions at the following link
If you are not sure which receiver unit you have, then use this document:

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.
