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.
