Is your 2010 Acura TL key fob’s switchblade feature malfunctioning, leaving the blade hanging loose? Or perhaps you’ve found a great deal on a used key fob online, only to realize the blade is cut for a different vehicle? Don’t worry, replacing just the blade is a straightforward DIY task that can save you money compared to buying a complete new key fob. This guide will walk you through each step of replacing your 2010 Acura TL key fob blade, allowing you to restore your key to perfect working order.
Tools You’ll Need
Before you begin, gather these essential tools:
- Precision Phillips screwdriver (PH0 and PH1)
- New uncut key blade replacement for Acura TL (ensure compatibility with 2010 models) – Available on platforms like eBay.
Step-by-Step Guide to Replacing Your Acura TL Key Fob Blade
Follow these detailed instructions to replace your 2010 Acura TL key fob blade quickly and efficiently:
Step 1: Remove the Screw
Locate the single screw at the bottom of your Acura TL key fob. Using your PH0 precision Phillips screwdriver, carefully unscrew and remove it. Keep the screw in a safe place to avoid losing it.
Step 2: Detach the Remote Housing
With the screw removed, gently pry open and detach the remote portion of the key fob. You can do this by pushing upwards on the key ring area. The remote housing should separate from the blade mechanism.
Step 3: Pry Open the Blade Cover
Now, carefully pry open the blade cover. Start from one side and gently work your way around. The cover is held in place by a sticky adhesive and two clips. Patience is key here – pry slowly to avoid damaging the cover.
Step 4: Unscrew the Blade Mechanism
You will now see three small screws securing the blade mechanism. Use your precision Phillips screwdrivers – PH1 for the two black screws and PH0 for the silver screw. These screws may have a thread-locking compound, so ensure you use the correct screwdriver size to prevent stripping the screw heads.
Step 5: Swing the Metal Piece
After removing the screws, the metal piece should now be able to swing counterclockwise. This movement is due to a spring located underneath it.
Step 6: Remove the Metal Piece and Spring
Carefully remove the metal piece, being mindful not to bend or lose the spring underneath it. Set both the metal piece and spring aside in a safe spot.
Step 7: Remove the Spring
Now, remove the spring from its position.
Step 8: Extract the Old Blade
With the spring and metal piece removed, you can now easily extract the old, worn-out blade from the key fob mechanism.
At this stage, you should have the disassembled components as shown in the image below:
Step 9: Prepare the New Blade and Immobilizer Chip
Take your new, uncut Acura TL key fob replacement blade and compare it to your old blade to ensure they are the same type. Locate the immobilizer chip, which is typically behind a small plastic door on the old blade. Carefully remove the immobilizer chip from your old blade and install it into the designated slot in your new blade. This step is crucial as the immobilizer chip is necessary for your key to start your car.
The issue with your old blade likely stems from a worn-out slot that no longer securely holds the blade in the closed position. The new blade will have a fresh, intact slot, resolving this problem.
Step 10: Assemble and Get Key Cut
Place the new blade into the key fob mechanism and reassemble all the components in reverse order of disassembly. Ensure the spring is correctly positioned for the switchblade mechanism to function properly. Once reassembled, you will need to take your key to a locksmith or key cutting service to have the new blade cut to match your vehicle’s ignition.
Important Note: This DIY blade replacement is primarily for 2007-2008 Acura TL models and likely applicable to the 2010 Acura TL as well, given the similar key fob design. While blank blades are readily available, ensure compatibility for your specific 2010 Acura TL model before purchasing.
Conclusion
Replacing your 2010 Acura TL key fob blade is a cost-effective solution to fix a malfunctioning switchblade key. By following these steps, you can avoid the higher cost of a complete key fob replacement from the dealership. You can often achieve a fully functional switchblade key for around $43 by combining a used key fob and a new blade – a significant saving compared to dealer prices. Enjoy your newly functional and reliable Acura TL key fob!
