I wanted a more stock looking garage door opener for my new 94' Celica GT4, I didn't want to have a remote clipped to my sun visor forever. I discovered online you can wire a normal battery powered garage door opener into a momentary switch and mount that in the car. I went to the local junk yard and searched the mid 90's early 00's Lexus and Toyota and found a switch that would work in the stock "blank" locations under the dash near the steering wheel. (Pic below)

I recommend you bring the blank with you so you can compare while searching. I think it was from a Lexus, but I don't recall the exact vehicle or year range (looks like RX300 99-03 is my best guess). It is a powered seat memory button with three momentary switches, perfect for what I needed.

I then opened the garage opener and figured out which parts of the circuit board I needed to solder the wires to and which wires did what on the 3 button switch I grabbed. This switch was simple, the white/black wire was the ground, then each of the other three wires went to one of the three buttons on the front.

It was as simple as soldering the white/black to the common ground on the circuit board and then one of each of the other three wires to each pole of the three buttons of the GENIE remote I was using. I like that this switch has 3 buttons so I can use up to 3 garage door/gates in the future.

I have a spare I grabbed at the junk yard and plan to try to repaint the button's on the front. I chose to mount in the blank location next to the fuse panel so that I could get to the battery of the garage remote if needed to change the battery. The GENIE remote is 12v, so I believe I could wire it into the car easily enough, but the battery works for me for now.

Final result:

Very clever install! I like it!

Thanks man! Definitely fun to be tinkering on a celica again! Took longer at the junk yard than to solder the 4 wires. Super easy project.

I found one of the switches on Ebay if anyone is interested in the same idea, but doesn't have the pig tail of wires. Was fairly easy to find at the junk yard.

EDIT: here is one with the wires

One of the guys on alltrac.net figured out exactly where I got it, it was from a 99-03 Lexus RX300 for anyone looking for one.

Toyota P/N 84927-48010

It is on a panel like this:

Very cool, I dig it. If you only need a single button for the garage door opener (single door) then you can get custom switches from a variety of sellers with any logo you want.

I have seen a lot of those on eBay, but they all appeared to be for later model Toyota’s since the “blank” hole is a different shape/size. Do you know if they make some that fit the 6th gen blanks?

Radical man, when I get my own place I'll definitely want to try this out! Do you have any other plans for the other buttons? Lol

I have the "1" and "2" both set to garage doors since my garage has two separate doors. The "SET" one is not set to anything right now, but is ready to go if I need to program it to a garage or gate etc.

I did find a few other momentary style buttons at the junk yard, was torn which one to use, but wanted to be able to use both garage doors. These came out of an older toyota mini van to open the motorized sliding rear doors when pressed. I might take the security one and wire it into the microphone on my head unit for the hands free calling so that I can hide the aftermarket mic it came with that I currently have sitting on the top of the steering column. Not sure it would pick up well enough if I moved if lower on the dash where the other "blank" is, but worth a try since I have a spare Kenwood microphone to play with as well.
