Sears Garage door opener + control outdoor lights

["Chaotik" <chaotik@xxxxxxxxx>]

I have a Sears Craftsman garage door opener that came with a 3 button
multi function remote control that is supposed to be Homelink
compatible.
One of the buttons controls the door itself and the other 2 I was
hoping I could program to perform other stuff.

Mainly, I would like to have one of the other 2 buttons turn the
outdoor lights on and off from my car. They are not lights that I can
plug into an outlet. They are currently controlled by a wall light
switch inside the house. I was hoping I could simply replace that light
switch by one that is wireless enable (315 Mhz is the frequency my
Sears remote operates at).

I asked the technical support at X10 is their products would allow me
to do that.
I ended up buying 2 parts. 1 WS467 wall switch module and 1 TM751 Mini
Transceiver. Is that even right ? So far, I plugged a lamp into the
mini transceiver and tried to turn it on and off using the Sears remote
with no success. Do I need to do anything for the transceiver to
"learn" the remote ?
Is there a simpler way ?

Please let me know if you can help me ...
