How to Replace the Battery in a Genie ACSCTG Type 1 Remote
Replacing the battery is a simple DIY task that takes under 5 minutes. Follow these steps carefully:
Step-by-Step Instructions
- Locate the Battery Compartment
Turn your Genie remote over. You’ll see a small slot or seam near the bottom edge — that’s where the battery compartment opens. - Open the Remote Case
Use a small flathead screwdriver or coin to gently pry open the remote cover. Avoid using sharp tools that might crack the plastic casing. - Remove the Old Battery
Take out the old A23 battery. If it’s corroded, wipe the compartment clean with a dry cotton swab — do not use water or liquid cleaner. - Insert the New Battery
Place the new 12V A23 battery into the compartment. Ensure the positive (+) side matches the marking inside the remote. - Close the Remote Case
Snap the cover back on securely until you hear a click. - Test Your Remote
Press the remote button while pointing at your garage door opener. The door should respond immediately.
If the light on your opener blinks but doesn’t activate, recheck the battery polarity and ensure your remote is properly synced with the opener.
Signs Your Genie Remote Battery Needs Replacement
Knowing the symptoms can save you from getting locked out or stranded. Here’s how to tell if your Genie remote battery is dying:
- Delayed response when pressing the button
- Dim indicator light or no light at all
- Reduced range (you have to be closer to the door)
- Intermittent operation — sometimes it works, sometimes it doesn’t
🧠 According to Genie technical documentation, the remote battery typically lasts up to 24 months, but frequent daily use or extreme temperatures can shorten its life.

| No light, no function | Dead or reversed battery | Reinsert correctly or replace |

| Works on one door only | Multi-door setup | Reprogram for each opener |
How to Reprogram Your Genie Remote After Battery Change
