Experiencing issues with your 2006 Infiniti M45 Key Fob can be incredibly frustrating, especially when you rely on it daily for vehicle access and operation. One owner faced a series of unfortunate events while attempting to program a new key fob for their 2006 Infiniti M45, highlighting common challenges and potential underlying issues with these systems.
Initially, the owner of a 2006 Infiniti M45 only possessed a single functioning key fob. Seeking a backup, they opted for a more affordable aftermarket key fob from a Chinese vendor. In an attempt to program this new key fob, they visited a local Nissan dealership – the closest service center, as the Infiniti dealership was a considerable distance away. However, the programming process at the Nissan dealership took an unexpected turn for the worse. Not only did the programming of the new, cheaper key fob fail, but, surprisingly, the dealership inadvertently compromised the functionality of the original, previously working 2006 Infiniti M45 key fob.
Following the Nissan dealership’s unsuccessful attempt, the original key fob for the 2006 Infiniti M45 became partially disabled. The wireless functionalities, including the unlock buttons and trunk opener, ceased to operate entirely. The owner was then forced to resort to using the valet key simply to gain entry into their vehicle. Even starting the car became a cumbersome process; it required manually inserting the key fob into the designated key holder slot within the vehicle. This significantly reduced the convenience and seamless operation that is expected from a modern keyless entry system.
Undeterred, and now in need of a reliably working key fob, the owner decided to purchase a genuine Infiniti key fob directly from an Infiniti dealer, this time avoiding aftermarket options. Hoping for a better outcome, they returned to the same Nissan dealership to attempt programming this new, genuine Infiniti 2006 M45 key fob. Unfortunately, despite using a factory-original key fob, the Nissan technicians were again unable to successfully program the device to the vehicle. The owner remained in the inconvenient situation of having only the partially working original key fob and the inability to use any of its wireless features. The dealership, unable to resolve the issue during the initial visit, advised the owner to schedule a day-long appointment to further diagnose the problem.
Driven by the ongoing key fob issues and the lack of immediate resolution, the 2006 Infiniti M45 owner began researching potential causes for these programming failures. Their research led them to suspect a malfunction within the vehicle’s intelligent key unit, identified by part number 285E1-EH10C. They hypothesized that this unit might be failing to properly recognize signals from the remote keyless entry receiver, part number 28595-EH100, which is responsible for communicating with the key fobs. This line of inquiry raises a pertinent question: Is a faulty intelligent key unit the likely culprit behind the 2006 Infiniti M45 key fob programming problems and the subsequent loss of wireless functionality? Further diagnostics by a qualified technician specializing in Infiniti vehicles may be necessary to confirm this suspicion and implement the appropriate repair.
