This guide will walk you through the simple steps to replace your 2014 Acura Mdx Key Fob Battery and provide some insights into battery life.
What Battery Type Does the 2014 Acura MDX Key Fob Require?
The 2014 Acura MDX key fob uses a CR2032 3V lithium coin cell battery. This type of battery is widely available at most drug stores, grocery stores, electronics retailers, and online. You can easily find brands like Panasonic, Duracell, Energizer, and others. Having a spare CR2032 battery on hand is always a good idea for preventative maintenance.
Step-by-Step Guide to Replacing Your 2014 Acura MDX Key Fob Battery
Replacing the battery in your 2014 Acura MDX key fob is a straightforward process that you can complete in just a few minutes with a few simple tools.
-
Remove the Mechanical Key: Locate the small release button on your key fob. Press and hold this button while pulling out the metal mechanical key. This key is a backup to manually unlock your car door if needed.
-
Open the Key Fob Casing: Once the mechanical key is removed, you will see a slot or seam where the two halves of the key fob casing join. Use a thin coin, like a penny or a dime, to gently pry open the casing. Insert the edge of the coin into the slot and twist carefully to separate the two halves of the fob.
-
Remove and Replace the Old Battery: With the key fob open, you’ll see the CR2032 battery. Take note of the battery’s polarity (positive (+) and negative (-) sides). Carefully remove the old battery. Install the new CR2032 battery, ensuring that the polarity matches the markings in the battery compartment.
-
Reassemble the Key Fob: Snap the two halves of the key fob casing back together until they are securely closed. You should hear a click indicating they are properly aligned.
-
Insert the Mechanical Key: Slide the mechanical key back into the key fob until it clicks into place.
Understanding Key Fob Battery Voltage and Lifespan
Key fob batteries, like the CR2032 in your 2014 Acura MDX fob, have a shelf life and degrade over time, even with minimal use. Testing the voltage of old and new batteries can provide interesting insights. In typical scenarios, a new CR2032 battery will measure around 3.2V. Used batteries, even after a couple of years, might still read close to 3V.
While batteries may still show a decent voltage reading after a few years, their capacity to deliver consistent power weakens. This is why proactive replacement is recommended. Factors like temperature extremes and humidity can also impact battery life.
Conclusion: Proactive Battery Replacement for Peace of Mind
Replacing your 2014 Acura MDX key fob battery is a quick, inexpensive, and proactive maintenance step. By changing the battery every couple of years, you can avoid the inconvenience of a dead key fob battery at an inopportune moment. Keep a fresh CR2032 battery on hand and follow this simple guide to ensure your key fob remains reliable for years to come.
