Experiencing issues with your 2008 Infiniti M35 Key Fob can be incredibly frustrating. Imagine relying on just one key fob for your vehicle and deciding to get a backup for peace of mind. One Infiniti M35 owner faced this exact situation, opting for a more affordable aftermarket key fob as a spare. However, attempting to program this new key fob at a local Nissan dealership, a series of unfortunate events unfolded, leading to more problems than solutions.
The initial attempt to program the aftermarket key fob didn’t go as planned. Worse still, the programming process somehow compromised the functionality of the original, and previously working, key fob. Suddenly, the owner’s primary key fob would only function when physically inserted into the ignition slot. The convenience of remote unlocking, locking, and trunk access was lost. Using the valet key became necessary just to enter the vehicle, followed by the cumbersome process of inserting the fob into the designated slot to start the engine.
Seeking a solution, the owner then purchased a genuine Infiniti key fob, hoping a factory-made remote would resolve the programming issues. Returning to the same Nissan dealership, they attempted to program the authentic Infiniti key fob. Unfortunately, this second attempt also failed, leaving the owner in the same predicament – reliant on the original, partially functional key fob and still needing to use the valet key for basic access. The wireless functionalities remained unresponsive, and the dealership, after their unsuccessful attempts, suggested an extended diagnostic appointment, requiring the car to be left for a whole day.
Frustrated by the ongoing issues, the Infiniti M35 owner began researching potential causes. Their investigation led them to suspect a malfunction within the vehicle’s intelligent key unit (part number 285E1-EH10C). This component, along with the remote keyless entry receiver (28595-EH100), is crucial for processing signals from the key fob. The owner questioned whether the inability to recognize signals from the remote unit could be the root cause of their key fob problems. Could a faulty intelligent key unit be preventing both the original and new key fobs from operating correctly, and is this a common issue with the 2008 Infiniti M35? This line of inquiry raises important questions for anyone facing similar Infiniti key fob troubles and warrants further investigation into the intelligent key system and its potential vulnerabilities.
