|Parts I used:
Radio Shack #275-1571 Momentary SPST Pushbutton
Take the left
side switch housing apart. Take out rocker switches. Drill a 3/16"
diameter hole in the left side of the switch housing - either top half
or bottom half [or BOTH] - see picture below for location. Take a Dremmel and clean out metal stubs, rocker switch bracket, rocker switch
button, and generally make the inside area larger to accept the switch.
You need to be proficient with a dremmel to make this fit. It is not
hard, but it does take persistence and several trial fittings to make it
fit correctly. Test fit with rocker switches in place. Once enough
material has been removed and the switch fits, solder two wires on the
switch, with enough length to route through the bars and reach the
placement of the transmitter. On my Fatboy, I mounted the Genie Keychain
transmitter in the headlight tin FL nacelle via velcro. Different
transmitters/brands, at different frequencies, behave differently when
subjected to a metal enclosure. Test fire your particular transmitter,
say at the end of your driveway, with the remote located at its final
resting spot. It would be a shame to go through all this and the remote
not work due to inadequate placement.
Place the pushbutton switch in the housing and secure with JB Weld on
the inside, tape it up and walk away from it for 24 hours to cure.
Replace rocker switches into housing, route wires though bars. Take the
remote apart and locate the switch on the printed circuit board that
operates the door. Solder the new switch wires in parallel across this
printed circuit board switch. Velcro transmitter in place. You can even
get fancy and mount a jack on the transmitter, to disconnect your wires
via a plug if you need to take the transmitter off for whatever reason.
That's it....simple except for the Dremmel step. It does work out.
Why not just go with a commercial unit that piggybacks on your door
opener? Because the units I have seen use antiquated technology (i.e.
selectable DIP switches that are easily scanned and sniffed) whereas my
particular door uses rolling code technology - every transmission uses a
different rolling code.
Another analogy would be trying to operate a high end HDTV with
And yes, the price.....$30.00 for the remote, $3.00 for the switches.
