One of the most frequent culprits behind a “Remote Not Detected” message is, indeed, a low or dead key fob battery.

Over time, like any battery, the key fob battery will deplete and require replacement.

Identifying Key Fob Battery Issues
Before assuming a more complex problem, consider these telltale signs that your 2019 GMC Acadia key fob battery might be failing:

Replacing Your 2019 GMC Acadia Key Fob Battery
Fortunately, replacing the key fob battery in your 2019 GMC Acadia is a straightforward process that you can often do yourself. You’ll typically need a CR2032 battery, which is widely available at most drugstores, supermarkets, and auto parts stores.
While specific steps can vary slightly depending on your exact key fob style, the general procedure is as follows:
- Locate the Notch: Look for a small notch or release button on your key fob casing.
- Open the Fob: Use a small flathead screwdriver or your fingernail to gently pry open the key fob casing at the notch.
- Remove the Old Battery: Carefully remove the old CR2032 battery, noting the positive (+) and negative (-) orientation.

Replacing the battery in a key fob is a simple process that can resolve many remote issues.
Beyond the Battery: Other Potential Causes
If replacing the 2019 GMC Acadia key fob battery doesn’t resolve the “Remote Not Detected” issue, other factors might be at play:
- Signal Interference: Strong radio frequencies or electronic devices can sometimes interfere with the key fob signal. Try moving to a different location to see if the issue persists.
- Vehicle Battery Issues: Although less likely to directly cause a “Remote Not Detected” message, a weak car battery can sometimes lead to electrical system glitches. Ensure your Acadia’s car battery is in good condition.
- Receiver Problems: In rare cases, the receiver in your GMC Acadia that detects the key fob signal might be faulty. This would typically require professional diagnosis and repair.
- Key Fob Malfunction: While less common after a battery change, the key fob itself could be malfunctioning due to damage or internal issues.
Seeking Professional Assistance
