Is your Nissan Murano key fob suddenly refusing to cooperate? A malfunctioning key fob can be a major inconvenience, leaving you locked out or unable to start your vehicle. Fortunately, reprogramming your key fob can often resolve the issue, and you can do it yourself without a trip to the dealership. This guide provides a step-by-step process to reprogram your Nissan Murano key fob, potentially saving you time and money.
Step-by-Step Guide to Reprogram Your Nissan Murano Key Fob
Before you assume your key fob is broken, try reprogramming it. This process is designed to resynchronize your key fob with your Nissan Murano’s immobilizer system. Follow these instructions carefully for successful reprogramming:
-
Initiate the Programming Sequence: Begin by getting inside your Nissan Murano and ensuring all doors are completely closed and locked. Use the power lock/unlock button located on the driver’s side door to lock all doors.
-
Ignition Key Cycling: This step is crucial for entering programming mode. Insert your Nissan Murano key into the ignition cylinder and remove it rapidly at least six times within a 10-second timeframe. It’s important to fully remove the key from the ignition cylinder each time. If executed correctly, your Murano’s hazard lamps should flash, indicating that the system has entered programming mode. Note: While some models might provide a visual indicator inside the cabin, it’s more reliable to watch for the external hazard lamp flash, especially in a garage where the reflection can be easily seen. Avoid performing this step too quickly, as the system may not register the programming initiation.
-
Enter ACC Position: Immediately insert the key back into the ignition cylinder and turn it to the “ACC” (Accessory) position. This powers the vehicle’s accessories without starting the engine.
-
Activate the Remote Transmitter: Within five seconds of turning the key to the ACC position, press any button on the key fob remote transmitter you wish to program. Upon pressing a button, the hazard lamps should flash again to confirm successful programming of that key fob. Note: Press the button only once. Multiple presses can disrupt the programming sequence and lead to failure. If you press the “LOCK” button, you might hear the door locks attempting to engage.
-
Programming Additional Transmitters (Including Existing Ones): If you have additional key fobs to program, including previously programmed ones, you must program them now as well. Use the driver’s side power lock/unlock switch to unlock and then immediately lock all doors. Within five seconds of locking the doors, press any button on the next remote transmitter you want to program. The hazard lamps should flash to confirm successful programming. Repeat this step for every key fob you need to program, including any existing fobs, as reprogramming is necessary for all fobs to function after this procedure.
Troubleshooting and Important Considerations
While this programming procedure is generally effective, there are instances where it might fail. Here are some troubleshooting tips and important considerations:
- Incorrect Key Fob Model: Ensure that the key fob you are using is compatible with your Nissan Murano model year. Using an incompatible key fob model, such as one designed for a different year range (e.g., a KABRASTU15 model potentially intended for 2003-2006 models on a 2007 model), may result in programming failure. Always verify the correct key fob model for your specific Nissan Murano year and trim.
- Procedure Timing: The timing of each step is crucial. Ensure you are completing the ignition key cycling and button presses within the specified timeframes. If the procedure is performed too slowly or too quickly, the system might not enter or complete the programming mode.
- Battery Issues: A low battery in your key fob can also cause programming failures or intermittent operation. Before attempting to reprogram, replace the battery in your key fob with a fresh one to rule out battery issues.
- System Malfunctions: In rare cases, a failure to program the key fob might indicate an underlying issue with your Nissan Murano’s immobilizer system or receiver module. If you have diligently followed the programming steps and are still unable to program your key fob, it is advisable to consult a qualified automotive locksmith or a Nissan dealership for professional diagnosis and repair.
By following these steps carefully, you can often resolve a non-working Nissan Murano key fob issue. However, if problems persist, seeking professional assistance is recommended to ensure proper diagnosis and repair of any potential underlying vehicle issues.
