Is your 2018 Acura TLX key fob acting up? A common culprit is often just a low battery. Don’t worry, replacing the battery in your Acura TLX key fob is a straightforward process you can easily handle yourself. This guide will walk you through each step, saving you time and potentially money compared to dealership service.
Recognizing a Low Key Fob Battery in Your Acura TLX
Before you assume it’s a dead battery, be aware of the typical signs. If you find yourself needing to press the buttons on your key fob harder or closer to your 2018 Acura TLX for it to respond, it’s a strong indication that the battery is weakening. Another sign is inconsistent performance – sometimes it works fine, other times it’s unresponsive. Ignoring these early signs can eventually lead to a completely dead key fob, leaving you unable to remotely lock, unlock, or start your vehicle.

Step-by-Step Battery Replacement for Your 2018 Acura TLX Key Fob
Replacing the battery is a simple DIY task. Here’s what you’ll need and how to do it:
- Gather Your Tools: You’ll typically only need a small flathead screwdriver, or sometimes just your fingernail, to open the key fob casing. You’ll also need a new CR2032 battery – this is the standard battery for most modern key fobs, including your 2018 Acura TLX. You can find these at most drugstores, supermarkets, or online.
- Open the Key Fob: Look for a small notch or seam on your Acura TLX key fob. Using your flathead screwdriver (or fingernail), gently pry open the casing. Avoid using excessive force to prevent damage to the plastic.
- Remove the Old Battery: Once open, you’ll see the battery. Take note of its orientation (+ side up or down) before removing it. Gently pry out the old CR2032 battery.
- Insert the New Battery: Install the new CR2032 battery, ensuring it’s placed in the same orientation as the old one. You should feel it snap into place.
- Close the Key Fob: Carefully snap the key fob casing back together until it’s securely closed.
Choosing the Correct Replacement Battery
It’s crucial to use the right type of battery for your 2018 Acura TLX key fob. As mentioned, the CR2032 battery is the standard and correct replacement. Using a different type might not fit properly or could cause damage to your key fob. Always double-check the battery type before purchasing to ensure compatibility.

When to Seek Professional Assistance
While battery replacement is generally easy, there are situations where you might need professional help. If you encounter difficulty opening the key fob, or if after replacing the battery, your key fob still doesn’t work, it might indicate a more complex issue. In these cases, contacting a locksmith specializing in automotive keys or your Acura dealership is advisable. They can diagnose potential programming problems or other key fob malfunctions.
Replacing the battery in your 2018 Acura TLX key fob is usually a quick and simple fix. By following these steps, you can often resolve key fob issues yourself, keeping you on the road without unnecessary delays or expenses.
