Remote Learning Key Fob for B&D garage Door from Jaycar

Needed an extra Key Fob for my B&D Garage Door. Bought LA8992 Learning
Remote Key Fob Range 250-450MHz. The blurb about seems to say it works
with some garage doors.

The existing remote has freq 433.92 stamped on it.

When I take the new fob thru its learning routine it seems to search for
and lock into the existing frequency of the old remote. When I then go
and use it in the garage door the LED flashes on the main controller of
the garage door but the door does not activate and open.

Is there something I need to do on the main controller to get it to
recognise the new fob. Does anyone have any suggestions. If I can't get
it to work then I have 7 days to take it back.

 

Others may help you with a direct answer to your question. I came up with an
alternative solution for my Merlin opener. The range of the original remotes
was never great and seemed to be reducing. I bought a Jaycar remote control
RX unit with two mini TX key fobs. The RX unit was simply connected to the
switch terminal on the Merlin opener controller, and the power was taken
from a convenient 12v output that the Merlin also provided. This gave me two
extra controllers with adequate range, and the old controllers still work as
well. Under $100. Jaycar have a couple os suitable R/C units.

I did the exact same thing, but with the oatley fobs. I thought I was
origonal

 

I got the Jaycar Fob to work, once it had learnt tthe code, I had to get
to press a button on the receiver (main unit ) to get the fob
recognised.

Clever idea to install Tx/Rx combo across the main unit contacts.
