Experiencing problems with your 2004 Acura TSX key fob? It’s a common frustration, especially when a newly purchased vehicle comes with a non-functioning remote. Let’s troubleshoot why your key fob might not be working, focusing on battery issues and programming attempts.
You’ve recently acquired a 2004 Acura TSX with 122,000 miles, and the dealer provided a replacement key fob that isn’t responding. You’ve tried programming it using a method you found – turning the ignition on and off repeatedly while pressing the lock or unlock button – but without success. The LED on the fob lights up, and even a new battery replacement hasn’t resolved the issue.
Let’s explore potential reasons and solutions. First, while the LED indicates the fob is getting power, it doesn’t guarantee the battery is supplying sufficient voltage or that the fob is transmitting correctly. Although you replaced the battery, it’s worth double-checking a few things:
- Battery Type: Ensure you used the correct battery type for your 2004 Acura TSX key fob. Refer to your owner’s manual or the battery compartment for the correct specification. Common types are CR2032 or CR1620, but accuracy is key.
- Battery Installation: Confirm the battery is installed with the correct polarity (+ and – sides). A reversed battery will prevent the fob from working.
- New Battery Quality: While less likely, a new battery could be faulty or have a low charge. If possible, try another new battery from a different source to rule this out.
If battery checks don’t solve the problem, the issue might lie in the programming process or the car’s receiver. The programming method you described is a common approach, but its accuracy for the 2004 Acura TSX needs verification. Consult your Acura TSX owner’s manual for the precise key fob programming procedure. Incorrect steps or timing can lead to programming failure.
Furthermore, consider the possibility of a faulty receiver in your Acura TSX. The link you found, discussing a 2004 Acura RSX keyless entry problem, could offer clues. While the RSX and TSX are different models, they might share similar keyless entry system components. The linked resource suggests testing the receiver, which could be a more complex diagnostic step, potentially involving electrical testing. It’s important to note that diagnosing receiver issues often requires specialized tools and knowledge.
In conclusion, while a new battery is a common fix for key fob problems, for your 2004 Acura TSX, it’s crucial to verify battery specifics, confirm the correct programming procedure from your owner’s manual, and consider the possibility of a receiver malfunction if programming fails. If you’re uncomfortable with electrical diagnostics, seeking assistance from a qualified automotive technician or Acura dealership is advisable to accurately diagnose and resolve the key fob issue.
