I had an issue... We have a Craftsman garage door opener, and two remotes. The problem is that the remotes kept getting lost because they had no clips on them. My wife's car doesn't have a built in garage door button, so I started thinking of how to make them easily accessible, and not get lost as easy.

So I started by adding velcro to an empty spot on the dash board, and the remote. This just wasn't good enough for me though. So I got to thinking, and looking. I noticed a blank button in the dashboard that was fairly small, and right next to the steering wheel. So I got to work thinking of a solution....

I came up with installing a button on the blank cover, attaching the garage remote PCB to the button. So let's see how this goes..

Step 1: The Design

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.

<p>I was about ready to do this in my 2014 CRV, just too old and lazy to tear into the dashboard. But I have a simple upgrade I'm sure you will love. Buy a 3 volt regulator and bypass the coin battery completely! The one I used was an NTE 1904, under $4. And get a heat sink for it, though I doubt it will ever get warm enough to need one. Less than $5, and no more battery changes! And you won't need the relay Tpassrino suggested, because if you wire into the switched 12, it will be off when the key is out anyway.</p>
I made this and wired in a small relay so it only worked with the ignition key on. That way if the car is parked outside and unlocked, the button would not operate the door unless the key was on. Used the original remote case and kept it in the locked glove box. Worked great for me. Photo not available because I have changed vehicles.
<p>That blank panel has a switch in a different trim level. Just hit up a auto graveyard and pick up said switch. That way the switch for the door is hidden in plain sight. If the car is stolen anyone will just think that option is broken (unless they press the button near your home). </p>
i did this for my bike to it works way better as for what of the car is stolen they would have the opener ether way.
<p>Pretty cool. I don't get all these &quot;If your car is stolen, all a thief has to do is..&quot; statements. If you have the garage door opener in your car, does it matter if it clipped to your visor or a push button on the dash? Anyway, if I did do this, I would go more James Bond and put it next to the eject button under my seat.</p>
<p>I wish I had an ejector seat....</p>
<p>I have done a similar project, however, I used a voltage regulator and tapped into the car's battery rather than a coin cell.</p>
<p>Awesome... I thought about tapping into the car's power, but my wife is hoping to sell the car in the next year or so and wanted to avoid the complications of me removing it, or explaining to the dealership. With this option I can just buy a replacement blank cover. </p>
Excellent ible. I did this exact build for my street bike except enclosed the board and battery in a weather proof housing so that I could open up the door as I approached the house. All the comments about &quot;what if your car is stolen&quot; makes no sense. If anything, this is much safer. The thief would have to know what the button was for.
If the car gets stolen... The have te know where the button is for. And if the car gets stolen... You just turn off the remote control system of your garage.
If your car gets stolen... They have to know where you live.
well done instructable, nicely done. I agree with hiding the button, but you work with what you're given, and the car gave you what it had. good job.
True. But as said, it's no different than having the remote in the car. Or any other car that has programmable buttons in it.
<p>The work is very good, but a bit dangerous: if they steal your car, they have free access to your home.</p>
<p>As said ckoehler1904!</p>
<p>I like the idea - convenient, well documented and photographed. However, if your car is stolen, all a thief would need to do is look in your glove compartment, find your owner registration card (or search for &quot;Home&quot; on the GPS in your car) and then drive to your house to push that button and gain access to your house. (BTW, that's the same problem that exists with ANY garage door opener kept in a car.) Perhaps a better approach might be to HIDE the button just under the ledge of the dashboard or in a similar convenient place. That way a thief would not have &quot;push button&quot; access to your home...and you would also not need to drill a visible hole on your car's dashboard.</p>
