Is your 2007 Honda CRV key fob not working as reliably as it used to? It might be time for a battery replacement. Many Honda CRV owners find themselves facing this issue, and the good news is, replacing the key fob battery is a straightforward task you can easily do yourself, saving you a trip to the dealership and the associated costs.
Identifying the Right Battery for Your 2007 CRV Key Fob
The battery you’ll need is a CR1616. This 3V lithium battery might be considered somewhat uncommon, but it’s readily available once you know where to look. While you might not find it at every corner store, pharmacies like Walgreens are a good place to check. Big box stores and general retailers like Walmart or CVS might also stock them, though availability can vary. For convenience and potentially better prices, online retailers are also excellent sources for CR1616 batteries. Brands like Energizer are reliable options, and you may find versions made in different countries, such as Japan or Mexico.
Step-by-Step Guide to Replacing Your 2007 CRV Key Fob Battery
Replacing the battery in your 2007 Honda CRV key fob is a simple process that requires minimal tools. Here’s how to do it:
Tools You’ll Need
- A mini Phillips head screwdriver
Opening the Key Fob
- Locate the small Phillips head screw on the back of your key fob.
- Using your mini screwdriver, carefully unscrew and remove this screw. Be aware that it might be tight, possibly due to threadlocker used during manufacturing.
- Once the screw is removed, the key fob casing will split into two halves (bivalves). Gently pry them apart.
Accessing and Replacing the Battery
- Inside the key fob, you’ll see a black plastic inner cassette containing the electronics and the battery. This cassette also splits into two halves.
- Carefully pry open this inner cassette to reveal the battery and the electronic components.
- The CR1616 battery will be visible. Remove the old battery.
- Take your new CR1616 battery and insert it into the slot. Ensure the positive (+) side of the battery (the side with the writing) is facing down, so the writing is not visible once installed. It’s recommended to use a cloth when pressing the battery into place to avoid touching the battery contacts with your fingers.
Reassembling the Key Fob
- Carefully close the inner cassette, ensuring both halves are securely snapped back together.
- Reassemble the two halves of the key fob casing.
- Replace and tighten the Phillips head screw. Be firm but avoid over-tightening to prevent stripping the screw.
Tips for a Smooth Battery Replacement
- Stubborn Screw: If you encounter a very tight screw, as mentioned, it might have threadlocker. To loosen it, you can use a vice-grip to get a better hold on the screwdriver and apply significant downward pressure while turning. Work on a soft surface like a terrycloth to protect the key fob from scratches.
- Battery Polarity: Always double-check the correct orientation of the battery (+ side down) before reassembling to ensure proper function.
Replacing your 2007 Honda CRV key fob battery is an easy DIY task. By following these steps, you can avoid dealership service fees and get your key fob working like new again in just a few minutes.
