What Kind of Battery Does an Acura Key Fob Use?

Knowing what kind of battery your Acura key fob uses is crucial for keeping it functioning correctly. Whether you’re experiencing a weak signal or your key fob has stopped working altogether, a simple battery replacement often solves the problem. This comprehensive guide will walk you through everything you need to know, from identifying the correct battery type to performing the replacement yourself.

Identifying Your Acura Key Fob Battery

Different Acura models and even different model years may use different key fob batteries. The most common types are CR2032 and CR2025, both 3-volt lithium coin cell batteries. The easiest way to determine the correct battery for your specific key fob is to consult your owner’s manual. This manual will clearly state the required battery type and provide instructions for replacement. Alternatively, you can search online using your Acura’s year and model, or even check the existing battery itself, which often has the type printed on it.

How to Replace Your Acura Key Fob Battery

Replacing the battery in your Acura key fob is usually a quick and straightforward process. While the exact steps might vary slightly depending on the key fob model, the general procedure is as follows:

1. Locate the release latch or button: This is typically a small button or switch on the side or back of the key fob.
2. Separate the key fob halves: Use the release latch or a small flat-head screwdriver to gently pry open the key fob casing. Be careful not to damage the plastic.
3. Identify the battery: Once the key fob is open, locate the battery. It should be easily accessible.
4. Remove the old battery: Gently pry out the old battery using your fingernail or a small flat-head screwdriver. Avoid puncturing the battery.
5. Install the new battery: Place the new battery into the compartment, ensuring the positive (+) side is facing up, just like the old battery.
6. Reassemble the key fob: Align the two halves of the key fob and snap them back together.
7. Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Where to Buy Acura Key Fob Batteries

Acura key fob batteries are readily available at most auto parts stores, electronics retailers, and online marketplaces. You can also purchase them directly from your Acura dealership. Be sure to buy a reputable brand to ensure quality and performance. Buying in bulk can also be a cost-effective option, especially if you have multiple Acura vehicles or anticipate needing to replace the battery again in the future.

Why is My Acura Key Fob Not Working Even After Replacing the Battery?

Sometimes, even after replacing the battery, your Acura key fob might still not function correctly. This could be due to several reasons, including:

• Faulty key fob: The key fob itself may be damaged.
• Programming issues: The key fob may need to be reprogrammed to your vehicle.
• Vehicle issues: There might be a problem with your car’s keyless entry system.

If you’ve replaced the battery and your key fob is still not working, it’s best to consult a qualified automotive locksmith or your Acura dealership for further diagnosis and repair.

“A common misconception is that all key fobs use the same battery. Always check your owner’s manual or the existing battery to confirm the correct type,” advises John Smith, Senior Automotive Technician at KEYFOBPROG.
