How to Install a Garage Door Opener in a Dashboard

Fairly simple. I took the PCB out of the remote, and soldered extensions on the main button that opens the door. Those extensions attached to the button. I then had to come with a solution to hold the battery. I happen to have a coin cell battery holder in my spare parts, they are usually no more than $.25 though. I found a way to attach the coin cell holder to the PCB, then soldered wires from the negative and positive terminals on the PCB to the coin cell leads.

All of these parts were recycled, or extra parts i had from past projects.

1. Garage Door Opener Remote (1)
2. Breadboard wires (4)
3. 2016 Coin Cell Battery (1)
4. Coin Cell Battery Holder (1)
5. Quick Release Pushbutton (1)
6. Blank Dashboard Butto
7. Solder

I needed these tools, once again nothing special.

1. Drill
2. ½" Drill Bit
3. Soldering Iron
4. Bench Vice

When I was changing a battery a few weeks ago I accidentally broke the clips that hold the two halves together, so I decided to canibalize that remote for the PCB.

1. Pry open the remote
2. find the clip that holds the PCB in place, and use a screwdriver to pry it back so that the PCB comes out easily.. Don't force it, you may want to put the PCB back in at a later date!!
3. Remove the PCB and find which button actually opens the door.
   1. For my remote it was SW3.
4. Look on the back of the PCB and trace the lines coming from that switch.
5. Locate the terminals on the PCB button that have traces coming from them.
   1. These are the terminals that you will have to solder the extension wires for the pushbutton.
6. Locate the positive and negative terminals for the battery. The positive was a bit tricky, but it was there

Find a blank button cover, this one in the 2007 Honda CR-V works great..

1. Locate a blank cover
2. Pry off the cover
3. Look at the internal structure of the cover. I had to remove a portion of it to fit my pushbutton in it flush. I just used a box cutter and the plastic came right off.

I bagan sizing up the pushbutton, and the blank cover.

1. I placed the cover in a batch vice to hold it steady while I drilled.
2. Drill a hold in the middle of the cover that the pushbutton can slide into. I drilled mine a bit to large, but was still able to make it work easily enough.
3. Place the pushbutton into the cover and check the fitting.
4. Install the cover back into the dashboard to check your clearance and fit.

This was essentially just connecting the terminals and everything so that I could verify that it was functional. This allowed me to see if the correct terminals on the PCB and the pushbutton terminals were connected properly. As always I recommend testing the circuit at every step that way you don't have to undo everything if there is an issue..

1. Attach the Coin Cell battery Holder. DO THIS WITHOUT THE BATTERY INSTALLED!!!
2. Solder the coin cell holder to the PCB and the positive and negative terminals.
3. Solder the pushbutton connections.
4. Check the clearance for the dashboard.
5. Test the circuit to make sure it works..

The video is the final product.

This all in all took about 2 hours to finish. That includes the time it took to figure out the solutions for the issues that arose. I didn't have to spend any money on this project, but assuming that you have solder, a soldering iron, and an already installed garage door opener then you could build it for about $8. The pushbutton is a standard $5 button from any hobby store, and the coin cell holder is only about a quarter. I had fun with this project, and it made life a bit easier.

I hope you enjoyed this tutorial, and as always I welcome any thoughts or comments you may have.
