How to Reset a Remote Control:

If you want to add another remote control for your garage door opener or need to replace a dead battery and reprogram an existing remote, chances are you'll have to reset the opener with the base unit for it to work. The process involves just a few steps and is relatively easy to do

• Replace the battery by opening the remote, taking out the old one(s) and putting in the new one(s). Make sure you buy the right battery for your remote. Match the battery type, size and voltage that came with the remote
• Use a step ladder to access the garage door motorized unit, usually equipped with a safety light. Locate the reset or "learn" button on the unit. Many times, this small button is recessed, so you might need a pen or pencil to reach it
• Push the reset or "learn" button on the opener. While the reset indicator light is blinking for about 30 seconds, point your remote at the opener, then press and hold the remote button that opens the door, and the reset light should stop blinking and glow steady to indicate the controller and opener are now synchronized. If the process doesn't work the first time, try again to make sure you pressed your button during the time when the indicator light is blinking

How to Build a Wireless Remote Control:

Simple wireless devices use various components to activate an infra-red signal that broadcasts to a receiver box, allowing the user to program the control. Basic wireless remote controls simply turn a device on or off. Components used in a wireless device can be found at most electronics outlets and hobby shops. Specialized retail establishments have pre-packaged kits that can be used by a beginner. At the very least, even experienced electronics enthusiasts use pre-made remote control boxes due to the simplicity of their design, including ergonomic support. The structure of the wireless remote control provides a builder with not only knowledge but the reasons a receiver can be controlled by the device

• Open the remote control housing and place a push button switch on the side. In the upper right corner of the housing, fasten a 3-volt battery holder. Be sure enough room is available to install and remove the battery
• Run a wire from the push button switch and link to the 3-volt battery holder at the negative connection. Attach another wire to the push button switch and lead it to the Meg 1/4W resistor and the NPN silicon transistor. Run a third wire from the Meg 1/4W resistor and attach it to the 22K 1/4W resistor and and the PNP silicon transistor
• Position the infra-red LED on the front of the housing. Attach the LED and run wires to both transistors. From the 22K 1/4W resistor, run a wire to the C220.01uF 16v ceramic disk capacitor. Run another wire between the NPN silicon transistor and the ceramic disk capacitor
• From the positive connector on the 3-volt battery holder, connect a wire to the PNP silicon transistor. This will allow for proper current flow in a closed circuit. Ensure the push button switch is positioned to "off" and place a 3-volt battery into the holder. Close the remote control housing
• Point the remote control at a receiver, making sure the LED on the control is aimed at the LED of the receiver. Push the button and the receiver should power on and off. To adjust the receiver to be programmed, point the remote control and hold down the push button switch. Adjust the pot or taper on the receiver
