Is your 2005 Infiniti G35 key fob suddenly not working? It can be frustrating when you’re locked out or unable to start your car remotely. Before you rush to a dealership or locksmith, you might be able to fix the issue yourself. This guide provides troubleshooting steps and instructions on how to reprogram your key fob for your 2005 Infiniti G35.
First, rule out the simplest issues. The most common reason for a key fob malfunction is a dead battery. Replacing the battery in your key fob is an easy and inexpensive first step. If a battery replacement doesn’t solve the problem, or if your key fob is still intermittent, reprogramming might be necessary.
Here’s how to attempt to reprogram your 2005 Infiniti G35 key fob yourself:
-
Ensure all doors are closed and locked. This is crucial for the programming sequence to initiate correctly.
-
Insert and remove your key from the ignition cylinder rapidly, more than six times within 10 seconds. Speed is important, but ensure the key is fully removed each time. If done correctly, your hazard warning lamps should flash, indicating the system has entered programming mode. Note: Some models may also flash side marker, tail, license plate lamps and interior lights twice to confirm successful entry into programming mode.
-
Insert the key into the ignition and turn it to the “AAC” (Accessory) position. This step registers the new key fob ID and erases any previously stored codes.
-
Press any button on the key fob you are programming just once. Avoid pressing the button multiple times. The hazard warning lamps should flash again to confirm successful programming. Note: Successful programming may also be indicated by two flashes of the side marker, tail, license plate lamps and interior lights.
-
If you have additional key fobs to program, immediately after step 4, unlock then lock the doors using the power door lock switch located on the power window master switch. Repeat step 4 for each additional key fob.
-
Remove the key from the ignition cylinder.
-
Unlock the driver’s side door, open the driver’s side door, and then close it. This completes the programming sequence.
After these steps, test all your programmed key fobs to ensure they are working correctly. If you continue to experience issues with your 2005 Infiniti G35 key fob after attempting this reprogramming procedure, it is recommended to consult a professional automotive locksmith or your Infiniti dealer for further diagnosis and assistance. There may be more complex issues at play, or the key fob itself could be faulty.
