Is your 2008 Honda CRV key fob starting to act up? Perhaps you’ve noticed you need to be closer to your vehicle for it to unlock, or maybe it’s stopped working altogether. Don’t worry, you might not need a new key fob! Often, the culprit is simply a dead battery. Replacing the battery in your 2008 Honda CRV key fob is a straightforward task you can easily do yourself, saving you time and money compared to a dealership visit.
Identifying the Right Battery for Your 2008 Honda CRV Key Fob
Before you begin, it’s crucial to have the correct replacement battery. For the 2008 Honda CRV key fob, you’ll need a CR1616 3V lithium battery. This type of battery, while not as common as AA or AAA, is readily available at most drugstores, online retailers, and battery specialty stores. You might find them under brands like Energizer or similar reputable manufacturers. It’s always a good idea to check the battery type printed on your old battery once you open the key fob to confirm, but CR1616 is the standard for this model year.
Step-by-Step Guide to 2008 Honda CRV Key Fob Battery Replacement
Replacing the battery is a quick and easy process. Here’s a step-by-step guide to help you through it:
Tools You’ll Need
- A small Phillips head screwdriver (often called a mini or micro Phillips screwdriver)
- A new CR1616 3V lithium battery
- A soft cloth (like terrycloth) to protect the key fob
Opening the Key Fob
- Locate the screw: On the back of your 2008 Honda CRV key fob, you’ll find a small Phillips head screw.
- Unscrew carefully: Use your mini Phillips screwdriver to carefully remove this screw. It might be a little tight, as manufacturers sometimes use a thread locking compound. Apply firm, steady pressure while turning to avoid stripping the screw head. The original article mentions using vice-grips for extra leverage, but careful, firm pressure with a good quality screwdriver should usually suffice.
- Separate the fob halves: Once the screw is removed, gently pry open the two halves of the key fob. They should separate relatively easily.
Replacing the Battery
- Open the inner cassette: Inside the key fob, you’ll see a black plastic cassette containing the electronics and the battery. This cassette also splits into two halves. Gently pry this open as well.
- Remove the old battery: You’ll now see the old CR1616 battery. Take note of its orientation (usually the positive (+) side with writing faces down, so you can’t see it when installed). Carefully remove the old battery.
- Install the new battery: Take your new CR1616 battery and place it into the battery slot in the same orientation as the old one. Use a cloth to press the battery into place, avoiding touching the battery contacts directly with your fingers. This helps prevent transferring oils and ensures a good connection.
Reassembling the Key Fob
- Close the inner cassette: Snap the two halves of the inner cassette back together.
- Reassemble the fob halves: Align the two halves of the key fob and press them firmly together until they snap closed.
- Replace the screw: Reinsert the Phillips head screw and tighten it securely, but don’t overtighten.
You’ve now successfully replaced the battery in your 2008 Honda CRV key fob! Test it out to ensure it’s working correctly.

Tips for a Smooth 2008 Honda CRV Key Fob Battery Replacement
- Work on a soft surface: As mentioned in the original article, use a terrycloth or soft towel on your work surface to prevent scratching or damaging your key fob.
- Be patient with the screw: If the screw is tight, don’t force it. Ensure you are using the correct size Phillips head screwdriver and apply firm, even pressure.
- Check battery orientation: Always double-check the orientation of the old battery before removing it and install the new one in the same way.
- Battery shelf life: Key fob batteries, like all batteries, have a shelf life. Even spare key fobs that aren’t used regularly can experience battery depletion over time. It’s a good idea to replace the battery in your spare fob proactively as well.
- Where to buy batteries: Besides drugstores and online, check electronics stores, and even some grocery stores may carry CR1616 batteries.
Cost Savings: DIY vs. Dealer for Key Fob Battery Replacement
The original author noted that a dealer quoted $15 for a key fob battery replacement. Considering that a CR1616 battery costs around $5 or less, replacing it yourself can save you a significant amount of money. Plus, it’s a quick and convenient task you can do at home in just a few minutes, avoiding the need to schedule a service appointment and wait at the dealership. By following these simple steps, you can keep your 2008 Honda CRV key fob working perfectly without unnecessary expense.
