Experiencing trouble starting your 2012 Acura TL can be frustrating. If you’re facing this issue, especially if it seems intermittent, considering the key fob and immobilizer system is a smart first step. A recent discussion with a bonded locksmith provided some valuable insights into diagnosing and potentially resolving a no-start condition in this model, focusing on key-related problems. Here’s a breakdown of recommended troubleshooting steps.
One of the initial recommendations was to assess the car’s dashboard indicator lights when attempting to start. Specifically, for a 2012 Acura TL, the locksmith suggested looking for a green light indicator. The presence of this green light is crucial because it signals whether the immobilizer system is engaged or not. If the green light illuminates, it typically indicates that the immobilizer system might be the culprit, meaning the car’s ECU (Engine Control Unit) isn’t recognizing the transponder chip within your key.
To further investigate the key itself, the locksmith offered a diagnostic service. By bringing in just the key, they possess a device capable of verifying if the embedded chip is functioning correctly. This step is essential in isolating whether the problem lies within the key’s transponder chip or elsewhere in the vehicle’s system. If the key is identified as the source of the problem, replacement options were discussed. Acura folding keys were quoted at around $200 for a replacement, while a more economical Honda non-folding key alternative could be obtained for approximately $180. Furthermore, the locksmith mentioned the capability to reprogram keys if necessary, although pricing details for reprogramming weren’t specified in this initial consultation.
