Having a dead key fob battery can be a sudden inconvenience. If you own a 2009 Honda CRV, you might be wondering about the correct battery size for your key fob and how to replace it. The good news is, changing the battery in your 2009 Honda CRV key fob is a straightforward process you can easily do yourself, saving time and money.
The battery you’ll need for your 2009 Honda CRV key fob is a CR1616 battery. This is a 3V lithium coin cell battery. Interestingly, even if you have a spare key fob that you rarely use, the battery can still die due to its shelf life. It’s always a good idea to replace batteries in both your primary and spare key fobs to avoid being caught off guard.
You can purchase CR1616 batteries from various retailers. While they might be a slightly less common battery type than others, drug stores like Walgreens, and online marketplaces are reliable places to find them. Big box stores or general retailers might not always stock this specific size. Expect to pay around $5 per battery, though online options might offer better deals if you’re buying in bulk or looking for cheaper brands.
Replacing the battery is simple and requires just a few steps. First, you’ll need a mini Phillips head screwdriver. Locate the small screw on the back of your key fob. After removing the screw, the key fob casing will split open into two halves. Inside, you’ll see an inner black plastic cassette containing the electronic components and the battery. Carefully pry this cassette open – it also separates into two parts. You’ll now see the battery.
To remove the old battery and insert the new CR1616 battery, it’s recommended to use a cloth to press it into place. This prevents any oil or residue from your fingers from contacting the battery surfaces, which can sometimes affect performance. Ensure the positive (+) side of the new battery, which is usually marked with writing, is facing downwards when you install it, so the writing is not visible once placed in the compartment. Finally, reassemble the black plastic cassette and then snap the key fob casing back together, tightening the screw.

Be cautious when removing the initial screw, as it can be quite tight. Applying firm, steady pressure with your screwdriver is important to avoid stripping the screw head. Using a padded surface like a terrycloth while working can protect your key fob from scratches. This simple DIY task can save you a significant amount compared to dealership battery replacement services, which can cost upwards of $15 for a simple battery change. Replacing your 2009 Honda CRV key fob battery yourself is an easy way to maintain your vehicle and save money.
