How to Replace the Battery in Genie Garage Door Opener Remote Model ACSCTG Type 1
When your remote becomes unresponsive or works only intermittently, the battery is usually the culprit.
Follow these simple steps to replace it safely:
1. Gather Your Tools
You’ll need:

- A new A23 12-volt alkaline battery
2. Open the Remote Housing
- Locate the small seam along the side of your remote.
- Insert the flathead screwdriver into the notch.
- Gently twist the screwdriver until the case pops open.
⚠️ Be gentle — older plastic housings can crack if forced.
3. Remove the Old Battery
- Carefully lift out the old A23 battery.
- Pay attention to its orientation (positive side facing up).
4. Insert the New Battery
- Slide the new A23 battery into the slot.
- Ensure it’s snug and properly aligned.

How to Program Genie ACSCTG Type 1 Remote
If your remote doesn’t operate your garage door, it may need reprogramming — especially after a battery change or power outage.
Follow this easy reprogramming guide:
Step 1: Locate the “Learn” Button
- On your Genie opener unit, find the “Learn” or “Program” button (usually near the antenna wire).
Step 2: Press and Hold
- Press and hold the “Learn” button until the indicator LED begins blinking (about 3 seconds).
Step 3: Press the Remote Button
- Within 30 seconds, press and hold the remote’s main button until the garage door opener light flashes or you hear a relay click.
Step 4: Test the Remote
- Press the button again to ensure the door operates smoothly.
💡 If you have multiple Genie openers, repeat this process for each unit.
Why the Genie ACSCTG Type 1 Remote May Stop Working
Even with a new battery, your remote may still fail. Here are common reasons and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| LED light doesn’t turn on | Dead or reversed battery | Replace or flip battery orientation |
| Door doesn’t move | Remote lost programming | Reprogram using “Learn” button |
| Short range | Weak battery or interference | Replace with a new battery / move closer |
| Works intermittently | Dirty internal contacts | Clean contacts with a cotton swab and alcohol |
| Doesn’t pair at all | Outdated remote | Replace with a Genie Intellicode-compatible remote |
Battery Comparison: A23 vs CR2032
Some users confuse the A23 with smaller coin cell batteries like the CR2032. Here’s a quick comparison:
| Battery Type | Voltage | Shape | Use Case |
|---|---|---|---|
| A23 | 12V | Cylindrical | Genie Type 1, keyless entry systems |
| CR2032 | 3V | Coin cell | Genie Type 3, car remotes |
✅ Verdict: Only the A23 12V fits the Genie ACSCTG Type 1 remote.
Expert Tips for Longer Battery Life
To make your remote last longer:
- Use quality batteries (Duracell or Energizer).
- Avoid extreme heat or humidity — store the remote indoors.
- Clean the battery terminals once a year to prevent corrosion.
- Replace batteries every 2–3 years, even if still functional.
- If not in use for long periods, remove the battery to avoid leakage.
According to Wikipedia, temperature and discharge rate significantly affect a battery’s lifespan — storing remotes in moderate temperatures (15–25°C) can double their longevity.
Troubleshooting: Still Not Working After New Battery?
If your Genie ACSCTG Type 1 remote doesn’t work after replacing the battery, here’s what to check:
- Verify correct battery polarity.
The positive end must face the correct terminal. - Check for corrosion.
White or green residue indicates corrosion — clean carefully. - Reprogram your remote.
If the opener lost memory, follow the programming steps above. - Inspect the opener’s antenna wire.
If it’s broken or bent, signal range will be reduced. - Replace the remote.
If internal circuitry fails, replacement remotes are available online for $20–$30.
