Is your 2010 Honda CRV key fob not working as reliably as it used to? You might be facing a common issue: a dead key fob battery. Interestingly, even if you have a spare key fob that you rarely use, the battery can still drain over time. The good news is that replacing the battery in your Honda CRV key fob is a straightforward process you can easily do yourself, saving you time and money compared to going to a dealership.
The battery you’ll need is a CR-1616, a 3V lithium battery. While it might not be available everywhere, you can typically find it at drug stores like Walgreens or online retailers. Brands like Energizer offer this battery, and you might find versions made in different countries, such as Japan or Mexico. Expect to pay around $5 per battery, but prices can vary, especially if you purchase online.
Replacing the battery yourself is a simple DIY task that should take just a few minutes. Here’s how to do it:
- Gather your tools: You will need a mini Phillips head screwdriver. Having a small cloth and possibly a pair of vice-grips can also be helpful.
- Open the Key Fob: Locate the small Phillips head screw on the back of your key fob. Using your mini screwdriver, carefully unscrew and remove it. Be patient, as this screw can be tight, possibly due to threadlocker used during manufacturing. If it’s very tight, using vice-grips to get a better hold on the screwdriver might be necessary, but apply steady, firm pressure to avoid stripping the screw head. Working on a soft surface like a terrycloth will protect your key fob from scratches.
- Separate the Key Fob Halves: Once the screw is removed, gently pry open the two halves of the key fob. They should separate relatively easily.
- Open the Inner Cassette: Inside the key fob, you’ll find a black plastic inner cassette that houses the electronics and the battery. This cassette is also in two halves. Carefully pry these halves open to access the battery.
- Replace the Battery: You will now see the CR1616 battery. Remove the old battery and take the new one. It’s recommended to use a cloth to handle the new battery and press it into place. This prevents oil and dirt from your fingers from affecting the battery contacts. Ensure you install the new battery with the (+) side (the side with the writing) facing down, so the writing is not visible once installed.
- Reassemble: Carefully snap the two halves of the inner cassette back together, then reassemble the two halves of the key fob. Replace and tighten the Phillips head screw. Don’t overtighten it, but ensure it’s snug.
By following these simple steps, you’ve successfully replaced your 2010 Honda CRV key fob battery! This quick DIY fix can save you a significant amount of money. Dealerships often charge around $15 or more just to replace the battery, making this a cost-effective and convenient solution for any Honda CRV owner. Enjoy the renewed reliability of your key fob!
