Is your Honda CRV 2012 key fob not working as reliably as it used to? You might be facing a common issue: a dead key fob battery. The good news is, replacing the battery in your Honda CRV 2012 key fob is a straightforward process you can easily do yourself, saving you time and money compared to dealership services.
Identifying the Right Battery for Your Honda CRV 2012 Key Fob
The battery you’ll need is a CR1616, a 3V lithium battery. While it might be considered a slightly less common size, these batteries are readily available at most drugstores and online retailers. Don’t be surprised if your local big-box building supply store or general retailers like Walmart don’t stock them; pharmacies like Walgreens or CVS are often a better bet for this specific type of battery. You can also find them online, sometimes at a more competitive price. Brands like Energizer are reliable options, and you might find versions made in Japan or Mexico.
Step-by-Step Guide to Replacing Your Honda CRV 2012 Key Fob Battery
Replacing the battery is a simple DIY task. Here’s how to do it:
- Locate the small Phillips head screw on the back of your Honda CRV 2012 key fob.
- Using a mini-Phillips screwdriver, carefully remove the screw. Be cautious as it might be on quite tight. The original poster noted that these screws can be initially very stiff, possibly due to threadlocker. Applying firm, steady pressure while turning is key to avoid stripping the screw head. You might even need to use pliers to get a good grip on the screwdriver for initial loosening.
- Once the screw is removed, the key fob casing will split open (bivalve) into two halves.
- Inside, you’ll see an inner cassette containing the electronics and the battery. Gently pry this inner cassette open. It also separates into two halves.
- Now you can access the battery. Carefully remove the old CR1616 battery.
- Install the new CR1616 battery. When inserting the new battery, use a cloth to press it into place. This prevents oil and dirt from your fingers from getting onto the battery contacts. Ensure the positive (+) side of the battery (the side with the writing) faces down when you install it, so the writing is not visible once placed in the slot.
- Reassemble the key fob cassette and the outer casing. Secure everything back together with the Phillips head screw.
Why DIY Battery Replacement is a Smart Choice
Opting to replace your Honda Crv 2012 Key Fob Battery yourself can save you a significant amount of money. Dealerships often charge inflated prices for simple services like battery replacements. The original poster mentioned a dealer quote of $15 just to replace the battery. By purchasing a CR1616 battery for around $5 and spending a few minutes of your time, you can easily avoid this unnecessary expense. Plus, it gives you the satisfaction of handling a minor car maintenance task yourself!
In conclusion, changing the battery in your Honda CRV 2012 key fob is a quick and easy task. By using a CR1616 battery and following these simple steps, you can restore your key fob’s functionality and save money in the process.
