Is your 2010 Honda CRV key fob not working as reliably as it used to? You might be facing a common issue: a dead or dying key fob battery. The good news is replacing it is a straightforward task you can easily do yourself, saving time and money compared to dealership service. Understanding the correct battery size is the first step to getting your key fob back in action.
The battery you’ll need for your 2010 Honda CRV key fob is a CR1616. This is a 3V lithium coin cell battery. It’s a compact and commonly used battery in small electronic devices, including car key fobs. Despite being readily available, it’s not always found in every store. While you might not spot it in large hardware stores, pharmacies like Walgreens or CVS, and online retailers are your best bet for finding a CR1616 battery. You can often find them in brands like Energizer or Duracell. Purchasing online can sometimes offer more competitive pricing, so it’s worth considering if you’re looking for the best deal.
Replacing the battery in your 2010 Honda CRV key fob is a simple DIY task. Here’s how you can do it:
- Locate the small Phillips head screw on the back of your key fob.
- Using a mini Phillips screwdriver, carefully unscrew and remove the screw. Be cautious as it might be tight. Applying firm and steady pressure while turning will help prevent stripping the screw head. It can be helpful to use a cloth on your work surface to protect the key fob casing from scratches.
- Once the screw is removed, gently pry open the key fob. It’s designed to split into two halves, revealing the internal components.
- Inside, you’ll find a black plastic inner cassette that houses the electronics and the battery. Carefully pry this cassette open as well. It also splits into two halves.

- You’ll now see the CR1616 battery. Take note of its orientation before removing the old battery.
- Remove the old battery and replace it with a new CR1616 battery. Ensure the positive (+) side of the battery (usually marked with writing) is facing down when you install it, so the writing is not visible once placed in the slot. Using a cloth or glove to handle the battery can help prevent transferring oils from your fingers to the battery contacts.
- Reassemble the inner cassette by pressing the two halves back together until they snap closed.
- Place the inner cassette back into the key fob casing and close the two halves of the key fob.
- Finally, re-insert and tighten the Phillips head screw. Make sure it is snug but not over-tightened.
By following these steps, you’ve successfully replaced the battery in your 2010 Honda CRV key fob. This simple maintenance can save you a trip to the dealership and the associated costs, as dealers often charge significantly more for a simple battery replacement. Keeping a spare CR1616 battery on hand can be a good idea to avoid future inconveniences with your key fob.
