What Battery Does an Acura Key Fob Use

The Acura key fob is an essential component for unlocking and starting your Acura vehicle. It allows for convenient entry and ensures that your vehicle is secure. However, like any battery-powered device, the key fob’s battery will eventually require replacement.

So, what battery does an Acura key fob use? The answer depends on the specific Acura model and year. Generally, most Acura key fobs use a CR2032 lithium coin cell battery.

Lithium coin cell batteries are widely used in electronic devices due to their compact size, high energy density, and long lifespan. They are also relatively easy to find and replace. If your Acura key fob uses a CR2032 battery, you can easily purchase a replacement from an automotive store or online retailer.

Steps to Replace the Battery in Your Acura Key Fob

Replacing the battery in your Acura key fob is a simple task that you can easily do on your own. Follow these steps:

  1. Identify the slot on the key fob where the battery resides. This slot is typically located on the back of the fob.
  2. Use a small flat-headed screwdriver or a coin to carefully pry open the slot. Be gentle to avoid damaging the key fob.
  3. Once the slot is open, remove the old battery from its place. Take note of the battery’s orientation so that you can insert the new battery correctly.
  4. Insert the new CR2032 battery into the slot, ensuring that it is properly aligned with the positive (+) and negative (-) markings.
  5. Close the slot by gently pressing it back into place until it snaps shut.

After replacing the battery, test the key fob by pressing its buttons. If the fob works properly, you have successfully replaced the battery. However, if the fob still does not function, try re-inserting the battery or consult an Acura dealer for further assistance.

Other Factors to Consider

While the CR2032 battery is the most common type used in Acura key fobs, it’s essential to check your vehicle’s specifications to ensure you have the correct battery size and model. Some Acura models may use different battery types, so it’s best to consult the owner’s manual or contact an authorized Acura dealer for accurate information.

It’s also worth noting that key fob usage can affect battery life. If you frequently use the key fob to lock and unlock your Acura vehicle or use features like remote start, the battery might drain faster than with minimal usage. It’s a good idea to have spare batteries on hand to avoid any inconvenience.
