Is your 2008 Honda CR-V key fob not working as reliably as it used to? A common culprit is a dead battery. The good news is, replacing the battery in your CR-V key fob is a simple DIY task that can save you time and money compared to going to a dealership. This guide will walk you through the process step-by-step.
What Battery Do You Need for Your 2008 CR-V Key Fob?
The 2008 Honda CR-V key fob uses a CR1616 battery. This 3V lithium battery, while not as common as some other sizes, is readily available at most drug stores and online retailers. Brands like Energizer and others offer this battery. You might find them at stores like Walgreens, or online for potentially better prices. Avoid dealerships or auto parts stores for inflated prices on this common battery.
Step-by-Step Guide to Replacing Your 2008 CR-V Key Fob Battery
Replacing the battery is straightforward and requires minimal tools. Here’s how to do it:
Tools Needed
- A small Phillips head screwdriver (often called a mini or micro Phillips screwdriver)
- A soft cloth (like terrycloth) to protect the key fob
Opening the Key Fob
- Locate the small Phillips head screw on the back of your 2008 CR-V key fob.
- Using your mini Phillips screwdriver, carefully unscrew and remove this screw. It might be tight, possibly due to threadlocker used during manufacturing. Apply firm, steady pressure while turning to avoid stripping the screw head. Using a vice-grip on the screwdriver handle for extra leverage can be helpful if needed, but be cautious.
- Once the screw is removed, the key fob casing will split into two halves. Gently pry the two halves 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 open.
- Carefully pry open this inner cassette to reveal the CR1616 battery.
- Note the orientation of the old battery (+ side facing down). Remove the old battery.
- Take your new CR1616 battery and, using a cloth to avoid touching the battery contacts with your fingers, press it into place in the cassette. Ensure the (+) side of the battery (the side with the writing) is facing down, matching the original battery’s orientation.
Reassembling Your Key Fob
- Carefully close the inner cassette until it snaps back together.
- Align the two halves of the key fob casing and press them firmly together until they are fully closed.
- Replace the Phillips head screw and tighten it securely, but don’t overtighten.
