Is your 2011 Honda CRV key fob starting to act up? Perhaps you’ve noticed it’s becoming less responsive, or maybe it has stopped working altogether. One of the most common culprits is a dead battery in your key fob. Fortunately, replacing the battery in your Honda CRV key fob is a straightforward process that you can easily do yourself, saving you both time and money compared to a dealership visit. This guide will walk you through each step to get your key fob working like new again.
The battery you’ll need is a CR-1616, a 3V lithium battery. You might find this particular battery type a bit less common in regular stores, as the original author experienced difficulty finding it in big box stores and pharmacies initially. Drug stores like Walgreens, or online retailers, are often your best bet for sourcing the CR-1616 battery. While the author found Energizer brand batteries made in Japan, and some made in Mexico, availability can vary. Purchasing online can sometimes offer more competitive prices and a wider selection.
To begin the replacement, you will need a mini Phillips head screwdriver. Place your Honda CRV key fob on a soft surface, like a terrycloth, to prevent any scratches or damage during the process. Locate the small screw on the back of your key fob. This screw can sometimes be quite tight, possibly due to thread locker applied during manufacturing. The original author even needed to use vice-grips for added leverage, being careful not to strip the screw head. Apply firm and steady pressure while turning the screwdriver to loosen and remove the screw.

Once the screw is removed, the key fob casing will split open into two halves. Inside, you’ll find a black plastic inner cassette containing the electronic components and the battery. Carefully pry open this inner cassette, as it also separates into two halves. With the cassette open, you will now see the battery nestled in its compartment.
Take note of the battery orientation before removing it. The positive (+) side, usually marked with writing, should be facing downwards, so you cannot see it when the cassette is opened. Using a cloth or gloved fingers to avoid touching the battery contacts directly, gently pry out the old CR-1616 battery and replace it with the new one, ensuring the (+) side is facing down in the same orientation as the old battery. Press the new battery firmly into place.
Now, carefully reassemble the inner cassette, then close the key fob halves, ensuring they snap back together securely. Finally, replace and tighten the small Phillips head screw. Avoid over-tightening to prevent damage.
And that’s it! You’ve successfully replaced the battery in your 2011 Honda CRV key fob. The dealership might charge around $15 for this simple service, but by following these steps, you’ve saved yourself money and gained a little DIY satisfaction. Your key fob should now be working perfectly, reliably locking, unlocking, and starting your Honda CRV once again.
