How to Install a Honda Integrated Garage Door Opener

By Nathan McGinty, eHow Contributor

There's not much more annoying than pulling into your driveway in your car only to find that you've left your garage door opener remote control inside the house. One way to prevent this hassle is by installing an integrated garage door opener in your car. An integrated garage door is a switch affixed permanently or semipermanently inside your car that allows you to open the garage door by remote control. This handy hack will work in many car models, including Hondas.

Things You'll Need

• Extra garage door opener
• Screwdriver
• Multimeter

Soldering iron

Solder

Insulated wire

Integrated switch

Wire cutters

Quick-fit wire connectors

1. • 1
     Obtain an extra garage door opener remote control for your door, if you have only one remote control. You will be cutting apart this unit, so make sure it's not the only garage door opener remote control you have. Purchase additional remote control units from your garage door opener manufacturer.
   • 2
     Loosen the screws on the opener remote control and pull the housing apart.
   • 3
     Examine the surface of the circuit board of the garage door opener, looking for the soldered connections directly beneath the push button. There may be four or eight soldered connections, depending on your remote control model.

     Press down on the garage door button and keep it affixed in place with a piece of duct tape. This will hold the circuit closed for testing. Take one end of the multimeter probe and touch one of the soldered connections. Touch the other end of the probe to an adjacent connection. Watch the needle on the multimeter. If it falls to zero, you have found the connections that you need to solder together. If not, try a different connection with the second multimeter probe. You're looking for the pairs of nodes that have zero resistance across each other for soldering together. Once you've found the first pair, continue working until you've identified all the nodes and their zero-resistance partners.

     Heat up the solder on the first connection with the tip of a soldering iron to soften it. Insert the end of the first bit of insulated wire. Apply solder to the top of the wire and melt it with the tip of the soldering iron. Repeat this process for the free end of the insulated wire, soldering it to the first connection's zero-resistance partner. Repeat the procedure of wiring the zero-resistance pairs together with the soldering iron and wire.

     Remove the 9V battery cap connection wires from the battery terminals on the circuit board by cutting it with wire cutters. Solder two more connections from the positive and negative battery terminals on the garage door opener.
   • 7
     Connect the wire connected to the negative battery terminal on the opener to the negative wire of a 9-volt battery cap that you cut off the circuit board earlier. Connect the positive terminal from the 9-volt cap to a wire with a Quick-fit connector switch at the end.
   • 8
     Connect the positive battery terminal on the opener to a wire with a quick-fit connector.
   • 9
     Look for a location on your Honda dashboard that can hold the body of the garage door switch comfortably. For example, in 2003 to 2007 Honda Accords, remove the fuse panel cover, and then the fuse panel collar, to reach an open area behind the dashboard. Also note that you'll need enough wiring to run from the switch in the dash to the garage door opener remote control location.

     Locate a connector switch that fits into one of the free sockets of your Honda dashboard. Find them cheap at online or physical retailers. You may need to test several until you find one that fits. Fasten a quick connector switch to the positive and negative terminals on the switch. Remove any unused switch panels on the dash, such as where optional accessories such as defroster switches might me mounted, and mount the new switch. How you'll mount the new switch depends on the type of kit that you purchased. Most will come with screws that can you can drive through the switch and into the dashboard.
   • 11
     Connect the 9-volt battery to the battery cap. Trim out any parts of the garage door opener as needed so the wires running out don't get bent, and fasten the garage door remote housing back together.
   • 12
     Mount the door opener remote control in a hidden part of your dashboard or glove box. Don't make the mounting permanent, as you will eventually have to change the battery.
   • 13
     Connect one wire from the switch to the battery assembly cap and the other to the garage door opener remote control by pressing the quick-fit connections together.
