Having trouble with your 2011 Honda Accord key fob? A common issue, especially as your vehicle ages, is a dead or dying key fob battery. You might notice the red LED light is weak or doesn’t illuminate at all when you press a button, or perhaps the range of your remote has significantly decreased. Before you assume there’s a more serious electronic problem, the first and easiest fix is to replace the battery. This guide will walk you through a straightforward 2011 Honda Accord Key Fob Battery Replacement.
Is it Just the Battery? Recognizing Key Fob Battery Issues
Before diving into the replacement, it’s helpful to confirm that the battery is indeed the culprit. Common symptoms of a low key fob battery in your 2011 Honda Accord include:
- Reduced Range: You need to be much closer to your car than usual for the remote to work.
- Intermittent Functionality: The key fob works sometimes but not others.
- Weak or No LED Light: The red light on your key fob may be dim or not light up when buttons are pressed.
- Inconsistent Button Response: You have to press buttons harder or multiple times for the car to respond.
If you’re experiencing these issues, a battery replacement is likely to solve the problem. It’s a quick, inexpensive fix that you can easily do yourself.
Step-by-Step Guide: Replacing Your 2011 Honda Accord Key Fob Battery
Replacing the battery in your 2011 Honda Accord key fob is a simple process that requires minimal tools. Here’s how to do it:
What You’ll Need
- A new CR1620 3V coin cell battery. This is the standard battery for most 2011 Honda Accord key fobs. You can find these at most drugstores, hardware stores, and online retailers.
- A small flathead screwdriver or a thin coin.
Opening the Key Fob Casing
-
Locate the Notch: On the back of your key fob, you’ll find a small notch or slot. This is where you’ll insert your flathead screwdriver or coin to open the case.

Battery Removal and Installation

Remove the Old Battery: You can usually pry out the old battery with your fingertip or the edge of your screwdriver. Be gentle to avoid damaging the surrounding components.

What if a New Battery Doesn’t Fix the Issue?
If you’ve replaced the battery and your key fob still isn’t working correctly, there might be a different issue. As the original poster mentioned, repeated battery drain could indicate an internal electronic problem within the key fob itself. In such cases, you might need to consider:
- Purchasing a New Key Fob: You can buy a replacement key fob online or from your Honda dealer.
- Programming the New Key Fob: New key fobs often require programming to work with your specific vehicle. This may involve a DIY programming procedure (check your owner’s manual) or a visit to a locksmith or dealership.
- Seeking Professional Help: If you’re unsure or uncomfortable with DIY solutions, a locksmith specializing in automotive keys or your Honda dealer can diagnose and fix the problem.
While battery replacement solves the most common key fob issues, understanding these next steps ensures you’re prepared for any eventuality with your 2011 Honda Accord key fob.
