As your trusted automotive experts at keyfobprog.com, we’re here to guide you through everything you need to know about Honda key fob batteries, focusing on the crucial question: What Size Battery For Honda Key Fob do you need? This guide will provide you with step-by-step instructions, helpful tips, and everything you need to confidently replace your Honda key fob battery and get back on the road.
Identifying Your Honda Key Fob and Battery Type
The first step in replacing your Honda key fob battery is determining the correct battery size. Honda uses various key fob designs across its models and years, but thankfully, identifying the battery type is usually straightforward.
Locating the Battery Information:
- Check the Back of Your Key Fob: Many Honda key fobs have the battery type printed directly on the back casing. Look for markings like “CR2032,” “CR1620,” or similar alphanumeric codes. This is the most direct way to find out what size battery for Honda key fob you require.
- Consult the Battery Itself: If the back of your key fob doesn’t specify the battery type, you’ll need to open the fob (we’ll guide you through this shortly). Once open, carefully remove the old battery and examine it. The battery size and voltage are typically printed on the battery itself. Common markings include a CR prefix followed by four digits (e.g., CR2032, CR1620, CR2025). These CR batteries are lithium coin cell batteries, widely available and known for their long life and reliability in devices like key fobs.
Common Honda Key Fob Battery Sizes:
While Honda uses several key fob designs, some battery sizes are more common than others. The most frequently used battery sizes in Honda key fobs include:
-
CR2032 Battery: This is perhaps the most common battery size for modern Honda key fobs. It’s a 3-volt lithium coin cell battery known for its longevity and power. You’ll often find the CR2032 in key fobs for models like Honda Civic, Honda CR-V, Honda Accord, and Honda Pilot, especially in recent years.
-
CR1620 Battery: Another 3-volt lithium battery, the CR1620 is slightly thinner than the CR2032. It’s also used in various Honda key fobs, particularly in some older models or specific key fob designs.
-
CR1616 Battery: This is a thinner 3-volt lithium battery and might be found in slimmer Honda key fobs.
-
CR2025 Battery: Slightly thinner than the CR2032 but thicker than the CR1620 and CR1616, the CR2025 is another 3-volt option that may power your Honda key fob.
Important Note: Always double-check your specific key fob to confirm what size battery for Honda key fob you need. While CR2032 is common, variations exist. Using the wrong battery size can prevent your key fob from working correctly.
Step-by-Step Guide to Honda Key Fob Battery Replacement
Once you’ve determined what size battery for Honda key fob you need, gather the following simple tools:
- Small Screwdriver Set: Jeweler’s screwdrivers or a precision screwdriver set are ideal. You’ll likely need a Phillips head screwdriver and possibly a flathead screwdriver depending on your fob.
- New Battery: Purchase the correct replacement battery (e.g., CR2032, CR1620) from a reputable retailer. Hardware stores, drugstores, and online retailers typically stock these batteries.
Now, follow these steps to replace your Honda key fob battery:
-
Locate and Remove the Screw (If Applicable): Examine your Honda key fob. Many models have a small screw, usually on the back or side of the fob. If you find a screw, use a small Phillips head screwdriver to carefully remove it. Place the screw in a safe place so you don’t lose it.
-
Pry Open the Key Fob Casing: If your key fob has a screw, remove it first. Then, look for a small seam or notch on the key fob casing. This is where you’ll gently pry it open. You can use a flathead screwdriver or a thin plastic pry tool. Insert the tip of the screwdriver into the seam and gently twist to separate the two halves of the key fob. Be careful not to apply excessive force, as you could damage the casing. For some models without screws, you may only need to use the flathead screwdriver to gently pry the two halves apart.
-
Access and Remove the Old Battery: Once the key fob casing is open, you’ll see the circuit board and the battery. Take note of the battery’s orientation – observe which side is facing up (positive or negative). Gently pry the old battery loose. You can use your fingertip or the tip of a small flathead screwdriver to carefully nudge it out. Avoid touching the battery terminals with your bare fingers if possible, as oils from your skin can potentially reduce battery life.
-
Insert the New Battery: Take your new battery and insert it into the battery compartment, matching the correct positive (+) and negative (-) orientation as you noted with the old battery. The battery should snap or slide into place securely.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly together until they snap back into place. If your key fob had a screw, replace it and tighten it gently, being careful not to overtighten.
-
Test Your Key Fob: Once reassembled, test your Honda key fob to ensure it’s working correctly. Try locking and unlocking your car, using the panic button, and any other functions your key fob offers.
Troubleshooting and Tips for Honda Key Fob Batteries
- Key Fob Still Not Working? If your key fob doesn’t work after replacing the battery, double-check that you installed the battery with the correct polarity (+ and -). Also, ensure you used the correct battery size. If it still doesn’t work, there might be another issue with your key fob, and it’s best to consult with a Honda service center.
- Battery Corrosion: If you notice any corrosion in the battery compartment, gently clean it with a cotton swab and a bit of rubbing alcohol before inserting the new battery.
- Battery Life: Honda key fob batteries typically last for a few years. Battery life can be affected by usage frequency, environmental factors, and battery quality.
- Purchasing Batteries: Buy replacement batteries from reputable brands to ensure quality and longevity.
