Is your 2011 Honda CRV key fob starting to act up? You might notice the range decreasing, or perhaps it’s becoming unresponsive altogether. Before you rush to the dealership and spend unnecessary money, the solution might be as simple as replacing the battery. This guide will walk you through how to easily replace your 2011 Crv Key Fob Battery yourself, saving you time and money.
Replacing the battery in your 2011 CRV key fob is a straightforward task that most owners can handle with minimal tools and effort. The battery you’ll need is a CR1616 3V lithium battery. These batteries, while not as common as AA or AAA, are readily available at most drug stores, online retailers, and even some larger grocery stores.
Here’s what you’ll need to replace your 2011 CRV key fob battery:
- A new CR1616 battery
- A small Phillips head screwdriver (often called a mini or micro screwdriver)
- A soft cloth (like terrycloth or microfiber) to protect your key fob
Once you have your supplies, follow these simple steps to change your 2011 CRV key fob battery:
-
Locate the small screw: On the back of your 2011 CRV key fob, you’ll find a tiny Phillips head screw. This screw holds the two halves of the key fob casing together.
-
Carefully remove the screw: Using your Phillips head screwdriver, gently unscrew and remove this screw. It can sometimes be a bit tight, as manufacturers often use a thread locking compound. Apply firm, steady pressure while turning to avoid stripping the screw head. Placing your key fob on a soft cloth can prevent scratches during this step.
-
Open the key fob casing: After removing the screw, you should be able to separate the two halves of the key fob casing. They should “bivalve” open, revealing the internal components.
-
Open the inner cassette: Inside the key fob, you’ll see a black plastic cassette that houses the electronics and the battery. This cassette itself is also in two halves. Carefully pry open this inner cassette. You might be able to do this with your fingernail or the edge of the screwdriver, but be gentle to avoid damaging the plastic.
-
Remove the old battery: With the inner cassette open, you’ll see the old CR1616 battery. Take note of how the battery is positioned, specifically the positive (+) and negative (-) sides. Gently remove the old battery.
-
Insert the new CR1616 battery: Place the new CR1616 battery into the slot, ensuring the positive (+) side is facing down, just like the original battery. It’s a good practice to use a cloth when handling the new battery to avoid transferring skin oils to the battery contacts, although this is not strictly necessary.
-
Reassemble the cassette and key fob: Carefully snap the two halves of the inner cassette back together, and then reassemble the two halves of the key fob casing. Replace and tighten the small Phillips head screw, being careful not to overtighten it.
-
Test your key fob: Once reassembled, test your 2011 CRV key fob to ensure it’s working correctly. The range should be restored, and the buttons should be responsive.

Tips for Replacing Your 2011 CRV Key Fob Battery:
- Tight Screw: If the screw is very difficult to remove, try using a slightly larger Phillips head screwdriver for a better grip. Applying more downward pressure can also help.
- Battery Polarity: Always double-check the polarity of the old battery before removing it and match the new battery’s orientation. Incorrect polarity can prevent the key fob from working.
- Battery Availability: If you can’t find a CR1616 battery at your local store, online retailers like Amazon are excellent resources. You might even find them cheaper online.
- Dealer Cost: Dealerships often charge a significant amount for a simple key fob battery replacement, sometimes as much as $15 or more, as mentioned in the original post. Doing it yourself saves you this unnecessary expense.
Replacing your 2011 CRV key fob battery is a simple DIY task that can save you money and keep your key fob working reliably. By following these steps, you can quickly and easily restore your key fob’s functionality and avoid a trip to the dealership.
