Is your 2009 Honda CRV key fob battery dying? You might notice the range decreasing, or perhaps it’s stopped working altogether. Before heading to a dealership and spending unnecessary money, you can easily replace the battery yourself. It’s a straightforward process that requires minimal tools and can save you a significant amount compared to dealer service.
Identifying the Correct Battery for Your 2009 CRV Key Fob
The battery you’ll need is a CR1616, a 3V lithium battery. This type might not be as common as standard AA or AAA batteries, but it’s readily available. You can typically find CR1616 batteries at drug stores like Walgreens or online retailers such as Amazon. While some larger stores like Walmart or building supply stores might not stock them, specialty pharmacies and online marketplaces are reliable sources. Keep in mind that prices can vary, and buying online might offer you a more cost-effective option.
Step-by-Step Guide to Replacing Your 2009 CRV Key Fob Battery
Replacing the battery in your 2009 CRV key fob is a simple DIY task. Here’s how to do it:
- Locate the Screw: On the back of your key fob, you’ll find a small Phillips head screw. This screw holds the two halves of the key fob together.
- Unscrew and Open: Using a mini-Phillips screwdriver, carefully remove this screw. It might be a bit tight initially as manufacturers sometimes use threadlocker. Apply firm, steady pressure while turning to avoid stripping the screw head. Placing a soft cloth on your work surface can protect the key fob from scratches.
- Separate the Key Fob Halves: Once the screw is removed, gently pry the two halves of the key fob apart. They should separate relatively easily, revealing the inner cassette containing the electronics and the battery.
- Open the Inner Cassette: The inner cassette itself is also in two halves. Carefully pry this open to access the battery compartment.
- Replace the Battery: You’ll see the CR1616 battery. Remove the old battery and replace it with a new one. When inserting the new battery, ensure the (+) side (usually marked with writing) is facing down, so you cannot see the writing once it’s in place. Using a cloth or gloved fingers to press the battery into place can prevent oil transfer to the battery contacts.

- Reassemble: Carefully reassemble the inner cassette, then snap the two halves of the key fob back together. Finally, replace and tighten the Phillips head screw. Don’t overtighten it.
Tips for a Smooth Key Fob Battery Replacement
- Dealing with a Tight Screw: If the screw is exceptionally tight, using a small vice-grip to get a better hold on the screwdriver can be helpful, but proceed with caution to avoid damaging the screw head.
- Battery Orientation: Double-check the battery orientation before fully reassembling. The positive (+) side should be facing down.
- Cost Savings: Dealerships often charge around $15 or more for this simple battery replacement. Doing it yourself saves you money and takes only a few minutes.
- Spare Key Fobs: Even spare key fobs that aren’t used regularly can experience battery drain over time due to shelf life. It’s a good idea to replace the batteries in all your key fobs around the same time.
By following these steps, you can easily replace your 2009 Crv Key Fob Battery and restore its functionality without incurring unnecessary expenses. This simple DIY task empowers you to maintain your vehicle and save money in the process.
