Is your 2008 Honda CRV key fob failing to unlock your doors or start your engine reliably? The most common culprit is a dead battery. Fortunately, replacing the battery in your key fob is a straightforward process you can easily do yourself, saving time and money compared to dealership service. Understanding the correct battery type and the steps involved will have your key fob working like new in no time.
The battery you’ll need for your 2008 Honda CRV key fob is a CR1616 3V lithium coin cell battery. This type of battery is readily available at most drug stores, online retailers, and even some larger grocery stores. You might find them under brands like Energizer or Panasonic. It’s a small, flat, round battery, and it’s essential to use the correct type to ensure proper function and longevity of your key fob.
Replacing the battery is a simple DIY task that requires minimal tools. Here’s a step-by-step guide to help you through the process:
-
Gather Your Tools: You’ll need a small Phillips head screwdriver, often described as a “mini” or “jeweler’s” screwdriver. A soft cloth can also be helpful to protect the key fob from scratches.
-
Locate the Screw: On the back of your Honda CRV key fob, you’ll find a small Phillips head screw. This screw secures the two halves of the key fob casing together.
-
Unscrew and Open the Casing: Using your Phillips head screwdriver, carefully remove the screw. It might be a little tight at first. Apply firm, steady pressure while turning to avoid stripping the screw head. Once the screw is removed, you should be able to gently pry open the two halves of the key fob casing.
-
Access the Battery Cassette: Inside the key fob, you’ll find a black plastic cassette that houses the electronics and the battery. This cassette is also in two halves. Carefully pry open this inner cassette. You might be able to use your fingernail or the edge of a small flathead screwdriver if needed, but be gentle to avoid damaging the plastic.
-
Replace the Old Battery: With the cassette open, you’ll see the CR1616 battery. Note the orientation of the battery before removing it – usually, the positive (+) side with the writing faces down, so you can’t see it when installed. Gently pry out the old battery. Take your new CR1616 battery and place it into the slot in the same orientation as the old one. Use a cloth to press it into place to avoid transferring oils from your fingers to the battery contacts.
-
Reassemble the Key Fob: Carefully close the inner cassette until it snaps shut. Then, align the two halves of the key fob casing and press them firmly together. Finally, reinsert and tighten the Phillips head screw. Don’t overtighten it, just make sure it’s snug.

By taking this simple DIY approach, you’ve avoided a potentially costly trip to the dealership, where battery replacements can often cost upwards of $15 or more. Keeping a spare CR1616 battery on hand can be a smart move to prevent future key fob battery emergencies.
