Replacing the battery in your 2012 Nissan Maxima key fob is a straightforward task you can easily handle yourself. This guide will walk you through the simple steps to get your key fob working like new again. The battery you’ll need is a common CR2032 3-volt battery, readily available at most drugstores, electronics stores, and online retailers.
Identifying the Correct Battery for Your Maxima Key Fob
The battery you need for your 2012 Maxima key fob is a CR2032. You might also see it listed under other designations like DL2032 or ECR2032, but these all refer to the same 3-volt battery type. It’s a small, round, flat battery. Before you begin, ensure you have a fresh CR2032 battery on hand.
Step-by-Step Battery Replacement Process
Changing the battery is a quick process. Here’s how to do it:
Tools Needed
- A new CR2032 battery
- A small flat-head screwdriver
Opening the Key Fob
First, locate the small latch on your key fob and slide it to release the mechanical key. Remove the key from the fob. Once the key is removed, you will see two small slots exposed on the key fob. Insert the tip of your small screwdriver into one of these slots. Gently twist the screwdriver. This will split the key fob casing open.
Battery Installation
With the fob open, you’ll see the battery. Take note of how the old battery is positioned before removing it. Gently pry out the old CR2032 battery. Install the new CR2032 battery in the same orientation as the old one. The battery should be installed face down, meaning the writing on the battery face will be hidden once installed, with the blank side facing up. Ensure it’s securely placed in the battery compartment.
Troubleshooting Low Key Fob Battery Issues
If you find that you are frequently replacing the battery in your 2012 Maxima key fobs, and the “low battery” warning appears soon after replacement, there might be an underlying issue. If both of your key fobs exhibit the same problem, it could indicate a problem with one of the antennas in your Nissan Maxima’s intelligent key system. This is less common but worth considering if new batteries don’t solve the problem. Diagnosing and fixing this type of issue requires specialized knowledge, so it’s best to consult with a qualified automotive service technician if you suspect an antenna problem.
Conclusion
Replacing the battery in your 2012 Maxima key fob is usually a simple fix. By following these steps, you can quickly restore the functionality of your key fob and avoid a trip to the dealership for a simple battery replacement. Keep a spare CR2032 battery handy so you’re always prepared to keep your key fob working reliably.
