Is your 2010 Acura TL key fob struggling to unlock your doors or start your engine? A common culprit is a dead or dying key fob battery. Fortunately, replacing the battery in your Acura TL’s switchblade key fob is a straightforward task you can easily accomplish at home with just a few simple tools. As a content creator for keyfobprog.com and an auto repair specialist, I’m here to guide you through each step of this process, saving you time and money compared to dealership service.
Before you begin, you’ll need one essential tool: a precision #0 Philips head screwdriver. This small, four-pointed screwdriver is crucial for accessing the battery compartment without damaging the delicate components of your key fob. You can find this type of screwdriver at any hardware store or online. Let’s get started and bring your 2010 Acura TL key fob back to life!
First, let’s identify the type of key fob we are working with. Below is an image showing the Acura switchblade key fob, similar to what you’ll be working with for your 2010 TL.
Step-by-Step 2010 Acura TL Key Fob Battery Replacement
Follow these detailed steps to replace your 2010 Acura TL key fob battery quickly and efficiently:
Step 1: Locate and Remove the Key Fob Screw
Turn your Acura TL key fob over to the side with the chrome loop. At the base of this loop, you will find a small screw. This is the only screw you need to remove to open the key fob. Using your precision #0 Philips head screwdriver, carefully insert it into the screw head.
Apply firm, steady pressure as you turn the screwdriver counter-clockwise to loosen and remove the screw. These screws can sometimes be tight due to threadlocker applied during manufacturing. If you encounter resistance, try gently tightening the screw slightly before attempting to loosen it again. This can help break the threadlocker’s hold.
Step 2: Separate the Key Fob Housing
Once the screw is removed, carefully separate the key portion from the remote portion of the fob. Turn the key fob so the side with the “Memory+” and other lettering is facing upwards. Press firmly on the chrome section of the key release button. You should notice a seam appearing along the center of the key fob as it begins to split into two halves.
With the chrome button still pressed, gently pull the two halves of the key fob apart. They should separate relatively easily now that the screw is removed.
You will now have the key fob separated into two main pieces: the blade portion and the remote control portion.
Step 3: Remove the Button Trim Piece
To access the battery compartment, you need to remove the button trim piece from the remote housing. Locate the side of the remote with the lock, unlock, and trunk buttons. Press down on any of these buttons from the outside. This action will release the trim piece from its internal clips, allowing it to pop out.
Once pressed, the button trim piece should detach easily from the remote housing. Set it aside carefully.
Step 4: Access the Battery Case
With the button trim removed, you’ll now see the internal case that houses the electronic components and the battery. This case is typically made of plastic and is designed to be water-resistant to protect the electronics.
Step 5: Open the Battery Case
To open the battery case, you’ll need to gently pry apart the two halves. Locate the seam or gap running around the center of the case, indicated in the image below.
Using your fingernails or thumbs, carefully apply pressure to this gap and gently pry the two halves of the case apart. The seal can be quite tight to maintain water resistance, so apply firm but controlled pressure. Avoid using excessive force or sharp tools that could damage the plastic case or internal components.
Continue prying around the seam until the case splits open, separating into two halves.
Step 6: Identify and Replace the Battery
With the case open, you will see the battery. Note the orientation of the battery before removing it, paying attention to which side is facing up (positive or negative). In this example, the negative side (dotted side) is facing upwards.
Gently lift the old battery out of its compartment. The 2010 Acura TL key fob typically uses a CR1616 3V lithium battery. Confirm the battery type in your key fob to ensure you purchase the correct replacement. You can find the battery type printed directly on the battery itself.
Install the new CR1616 battery, ensuring the polarity is correct (match the orientation of the old battery).
Step 7: Reassemble the Key Fob
Carefully snap the two halves of the battery case back together, ensuring they are firmly closed to maintain the water-resistant seal. Reinsert the button trim piece back into the remote housing until it clicks securely into place. Finally, align the two main halves of the key fob and press them together. Reinstall the small Philips head screw and tighten it securely, but avoid over-tightening.
Step 8: Test Your Key Fob
Once reassembled, test your Acura TL key fob to ensure it is working correctly. Try locking and unlocking your doors remotely, and starting your vehicle. If everything functions as expected, you have successfully replaced your 2010 Acura TL key fob battery!
Replacing your 2010 Acura TL key fob battery is a simple and cost-effective DIY project. By following these steps, you can avoid unnecessary trips to the dealership and keep your key fob working reliably. Remember to always use the correct CR1616 battery for optimal performance.
