If yous are annoyed past staring at a garage door opener hanging from your sun visor or are concerned nigh someone breaking into your car, opening your garage door with the remote control and breaking into your business firm, you can easily rewire your remote and hide information technology under the dash.

Forget about changing batteries, convert the voltage from the motorcar to drive the remote. Since the machine's accessory wire does not have power when the key is off, thieves volition not be able to open the garage if they do break in your car.

Precautions

This procedure applies to remote openers that piece of work with a 9-volt bombardment just. If your remote runs nether a different voltage, the circuit will be dissimilar.

Farthermost intendance must be taken when disassembling, testing and soldering. If not careful, you could harm the remote control.

To piece of work on this project you should feel comfortable soldering, messing with a circuit board and have some basic tools such as a soldering iron or station (y'all can purchase 1 for $x) and multimeter (voltmeter/ohmmeter).

Parts

7809 Positive ix-volt 1A voltage regulator
Push switch (normally open)
Small circuit board with holes (optional)
9-volt battery plug
Wires, electrical tape (or heatshrink)

Process

First, unplug and remove the battery, open the casing of the garage door opener remote control. Some units utilize screws and some are held together with pressure level snaps.

Once you get the circuit board out, locate the pressure switch that activates the circuit. With an ohmmeter, test the metallic terminals on the circuit board where the switch is located (about have more two pins). You have to notice 2 solder joints that get "continued" when the switch is pushed. If you lot are 100% sure you got the right tabs, hook upwardly the bombardment to the remote and short briefly the two tabs with a wire. If the garage door opens and closes, you lot accept found the right terminals.

Solder a wire to each of the two terminals at the switch in the circuit board. Be careful not to damage any components or brusk out any traces on the circuit lath.

Mount a switch somewhere on the dash or panel to operate the remote. Solder the ii wires that bypass the remote control'south switch to the external switch.

Build the excursion on the diagram (left) to step downwards the voltage from the vehicle'due south 12 volts (the circuit works for up to 35 volts) to 9 volts. Make sure that the bombardment plug is soldered BACKWARDS to the excursion (blackness to +12v ignition and red to ground). Once the circuit is built, claw it upwardly to the car'southward ignition (key on) output and test output voltage and polarity with a voltmeter.

If the voltage is ix volts and polarity is correct, plug up the voltage regulation circuit to the remote's bombardment last. Exam to make sure everything works. Wrap upwardly the circuit in electric record or heat compress to avoid shorts. Finally, hide the remote under the dash or somewhere else.
