Are you experiencing issues with your 2012 Acura TSX key fob? A common culprit is often a low or dead battery. As experts at keyfobprog.com, specializing in automotive key fob solutions and car repairs, we understand the frustration of a malfunctioning key fob. This guide will provide you with everything you need to know about your 2012 Acura Tsx Key Fob Battery Size, replacement, and related troubleshooting, ensuring you’re back on the road with a fully functional remote.
Understanding Your 2012 Acura TSX Key Fob
The 2012 Acura TSX, a vehicle praised for its blend of sporty performance and luxury, comes equipped with a sophisticated key fob system. This system allows for keyless entry, remote locking/unlocking, and in some models, even remote tailgate operation for the Sport Wagon variant. Understanding the power source of this crucial component – the battery – is the first step in maintaining its reliability.
Acura designed the TSX key fob for convenience and durability, but like all electronic devices powered by batteries, they will eventually need replacement. Knowing the correct battery size and how to replace it can save you time and money, preventing unnecessary trips to the dealership.
Identifying the Correct Battery Size for Your 2012 Acura TSX Key Fob
For the 2012 Acura TSX key fob, the standard battery size is a CR2032. This is a widely used 3V lithium coin cell battery, readily available at most drugstores, supermarkets, auto parts stores, and online retailers.
- CR2032 Battery Specifications:
- Type: Lithium Coin Cell
- Voltage: 3V (Volts)
- Dimensions: 20mm diameter, 3.2mm thickness
Using the correct CR2032 battery ensures optimal performance and longevity for your key fob. While other battery sizes may physically fit, they may not provide the correct voltage or amperage, potentially leading to unreliable operation or damage to your key fob.
Step-by-Step Guide to Replacing Your 2012 Acura TSX Key Fob Battery
Replacing the battery in your 2012 Acura TSX key fob is a straightforward process that you can typically accomplish in a few minutes with minimal tools. Here’s a step-by-step guide:
Tools You’ll Need:
- New CR2032 Battery: Ensure you have a fresh CR2032 battery.
- Small Flathead Screwdriver or Pry Tool: A small screwdriver or a plastic pry tool (like those used for phone repair) will be helpful to open the key fob casing.
Steps:
-
Locate the Notch: On the back of your Acura TSX key fob, you will find a small notch or indentation. This is the point where you will begin to open the casing.
-
Insert and Twist: Insert the tip of your flathead screwdriver or pry tool into the notch. Gently twist the screwdriver or pry tool. This should begin to separate the two halves of the key fob casing.
-
Open the Casing: Once you have created a small opening, carefully pry along the seam of the key fob to separate the two halves completely. Take your time and avoid using excessive force to prevent damaging the plastic casing.
-
Remove the Old Battery: With the key fob open, you will see the CR2032 battery. Note the orientation of the battery (usually positive side up). You may need to use your fingertip or the tip of the screwdriver to gently nudge the battery out of its holder.
-
Insert the New Battery: Place the new CR2032 battery into the battery compartment, ensuring the correct orientation (positive side usually facing upwards and marked with a “+” sign). Push down gently until the battery is securely in place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly together until they snap back into place. Ensure there are no gaps and the casing is securely closed.
-
Test Your Key Fob: Test the buttons on your key fob to ensure it is working correctly. Lock and unlock your doors, and if applicable, test the remote tailgate function on your TSX Sport Wagon.
Tips for Battery Replacement:
- Static Electricity: While handling the new battery, try to avoid touching the flat surfaces as much as possible to minimize the transfer of oils and static electricity, which can shorten battery life.
- Cleanliness: If you notice any dirt or debris inside the key fob casing, gently clean it with a soft, dry cloth before reassembling.
- Battery Orientation: Double-check the battery orientation before inserting the new one. Incorrect orientation will prevent the key fob from working.
- If it doesn’t work: If your key fob still doesn’t work after battery replacement, consider other potential issues outlined below or consult a professional.
Troubleshooting Common Key Fob Issues Beyond Battery Replacement
While a dead battery is the most frequent cause of key fob problems, other issues can sometimes arise. Here are a few troubleshooting steps to consider if a new battery doesn’t solve your problem:
- Check Battery Contacts: Ensure the battery contacts inside the key fob are clean and making good contact with the battery. You can gently clean them with a cotton swab and a bit of rubbing alcohol if necessary.
- Key Fob Synchronization/Programming: In rare cases, after a battery replacement, the key fob might need to be resynchronized with your vehicle. Consult your 2012 Acura TSX owner’s manual for specific instructions on key fob synchronization or programming procedures. Alternatively, your local Acura dealer or a locksmith specializing in automotive keys can assist with reprogramming.
- Signal Interference: Sometimes, strong radio frequency interference can temporarily disrupt key fob signals. Try using your key fob in a different location to rule out interference.
- Key Fob Damage: If your key fob has been dropped, exposed to moisture, or otherwise damaged, internal components might be faulty. In this case, key fob repair or replacement may be necessary.

- Vehicle’s Receiver Issues: Though less common, the issue could lie with the vehicle’s receiver system. If you suspect a problem with your car’s receiver, professional diagnostics by a qualified mechanic or Acura dealership technician are recommended.
