Is your Acura key fob starting to feel a little unresponsive? Like any battery-powered device, your Acura key fob relies on a small battery to operate, and eventually, it will need replacing. Luckily, knowing how to change the battery on your Acura key fob is a straightforward process you can easily do yourself.
What You’ll Need:
- A new CR2032 3V battery
- A small coin or flathead screwdriver
Step-by-Step Guide:
-
Remove the Mechanical Key: Locate the small button on your key fob and press it to release and remove the mechanical key. This is usually a small, rectangular button located on the side or bottom of the fob.
-
Open the Fob: Insert a coin or flathead screwdriver into the slot where you removed the key and gently twist to pry the two halves of the key fob casing apart. Be careful not to apply too much force to avoid damaging the plastic casing.
-
Battery Replacement: Carefully remove the old CR2032 battery. Take note of the battery’s polarity (+ and -). Insert the new CR2032 battery, ensuring the polarity is correct. The positive (+) side of the battery is usually marked.
-
Close and Test: Snap the two halves of the key fob casing back together until they are securely closed. Reinsert the mechanical key. Test your key fob to ensure it’s working correctly by locking and unlocking your Acura remotely.
Battery Life and Voltage:
A typical Acura key fob battery should last for a couple of years. Factors like usage and temperature can affect battery life. Checking the voltage of an old battery compared to a new one (around 3.27 volts when new, and potentially dropping to around 2.9V after use) can give you an idea of battery degradation, but proactive replacement is always a good idea to avoid being stranded.
Conclusion:
Changing your Acura key fob battery is a quick and easy maintenance task. By following these simple steps, you can ensure your key fob remains reliable and avoid potential headaches down the road.
