GICT 390-3BL garage door opener battery changing instructions needed

Hello -

You may need to re-set your garage door opener remote to sync with door opener. That has been the case for us when we experience a power outage. There is probably a switch on your garage door opener, near the ceiling of your garage, which you need to set while pressing the power button of the garage door opener remote control. We kept the user instructions which came with our garage door opener, so we can remind ourselves how to go about re-syncing. If you don't have the instructions for your garage door opener, you can probably find a source online by conducting a search with your favorite browser and entering the name of the garage door opener manufacturer and the model number. If you conduct such a search, I recommend you nest the manufacturer name and model number in quotation marks. Example: "Sears X123". Note: I also suggest you install new batteries in the remote before trying to set the remote to sync with the opener.

can you please provide the exact model number of your Security device...

Thanks

You may have to reconnect it to the garage door if you replaced the battery. There should be a "learn" button on the opener (usually a red square button (might be round). Read the manual but, in general, you push this button for only one second then go to your remote button and press that for several seconds. Again, the specific instructions may be different for your specific model year - they change from time to time. Check your owners manual for linking instructions.

It will only work if the new opener is a genie.

Replace the keypad.

You will find the instructions on this web site.

If its a lighter grey colored intellicode remote: There should be a small slot on the side of the remote. Use a coin such as a dime or a penny, stick it in the slot and twist. The remote should split in half and you'll see the coin-shaped battery. After you replace the battery, you can snap the 2 pieces of the remote back together.

If its a dark grey/black intellicode remote: The back cover should partially flip open to reveal the battery. This remote takes a 12volt N-size battery.

If its a keypad remote you are referring to: The bottom half of the keypad's face should slide straight down to reveal the battery (you should see and arrow and some thumb grips). All Genie keypads take 9volt batteries. Source(s): I am a genie technician
