Utilizing your Acura key fob (also known as a type of remote transmitter) is your gate to the luxury interior of your new or pre-owned Acura car or SUV. A key fob is required to activate your Engine Start/Stop button, and you'll at least need the spare key within it to unlock your vehicle. Issues with your key fob model are usually somewhat simple to fix, thanks to the Acura key fob battery replacement process. If you lose your key fob or require additional work on your current one, then trust Muller's Woodfield Acura to perform the Acura key fob replacement service you'll need.

Let's review some of the options you have when your key fob is unresponsive.

Acura Key Fob Troubleshooting at a Glance

  • Can I replace my own Acura key fob battery?: Yes, for most models, you can do this by taking out the spare key and using that to pry open the key fob, which is where you can begin a proper battery replacement.
  • What size battery does an Acura key fob use?: Most modern-day Acura key fobs use a CR2032 lithium cell battery, which looks like a silver disk.
  • Can I program my own Acura key fob?: While some older iterations may allow for at-home programming, most recent Acura vehicles require dealership equipment and expertise to properly program your key fob. Contact Muller's Woodfield Acura for more information.
  • How do I buy a new key fob?: You can purchase a brand-new key fob from a licensed Acura store, like at our location. That way, you can be sure it matches your model's requirements.

How To Change Battery in Acura Key Fob

Generally speaking, new Acura cars and SUVs come with similar key fob designs. That means even when time passes and the key fob becomes older, it's still relatively consistent to learn how to open. Acura key fob battery replacement follows these simple steps.

  • Step 1: First, you have to separate the key fob. Push the lever on the bottom to the other side and remove the silver piece.
  • Step 2: You'll notice that your spare key is on the end of the silver piece. Place the key into the divot above where it is normally stored and pry open the cover.
  • Step 3: Take a flathead screwdriver and place it just under the battery. Gently pry the battery out.
  • Step 4: Take your replacement CR2032 with the positive side facing outward and press it into the slot. Some models may require two batteries.
  • Step 5: Press the key fob's plastic components next to one another and press down on each side until you hear a click.
  • Step 6: Put your Emergency Key back into its normal place (the small opening on the side) and push down until you hear a click.

Press the unlock or open button and check to see that it flashes. Then, test it on your vehicle to make sure it is working as expected. If the key fob doesn't seem to connect to your Acura model correctly, then it may be time to visit our Acura service department to check the buttons or replace it.

If your vehicle remains unresponsive even after getting a new battery, you may need to consider an Acura key fob replacement. You can buy Acura parts from our store, including a brand-new key fob, and then you can visit us to get that new key fob in working order.

If your Acura model is old enough to have a key slot ignition (like it does for the Acura TL key fob), programming can be done by customers. To do so, follow these steps:

  • Step 1: Place your key into the ignition and turn it on.
  • Step 2: Press "lock" or "unlock" on the key fob within four seconds.
  • Step 3: Turn the key off.
  • Step 4: Repeat steps 1-3 two times.
  • Step 5: Repeat steps 1 and 2. Then, click lock or unlock one more time to confirm your programming.
  • Step 6: If you are programming more than one key fob, click "unlock" on any other models in the vicinity within 10 seconds.

Newer Acura models do not have this switch. So, you may need to utilize Acura roadside assistance to bring your model into our shop, where our mechanics will get your new key fob programmed correctly.

Frequently Asked Questions

What size battery does an Acura key fob take?

Your Acura key fob will usually take a lithium button cell battery, with modern units usually needing a size CR2032 battery. These are available in most utility stores or at our parts center at Muller's Woodfield Acura. Older key fob models may require a different battery size, such as a CR1616. Check your owner's manual for more information on what battery your specific key fob needs.

Can you start an Acura with a dead key fob?

Once you're inside the vehicle, you'll need to hit the Engine Start/Stop button, and while the light is flashing, press the back of the key fob (where the logo is) onto it. The beeper should sound, and the button should stay on for 10 seconds. Depress the brake and push the Start/Stop one more time. Otherwise, refer to your Owner's Manual Emergency Engine Start mode.
