Understanding Your 04 Nissan Murano Key Fob

Your 2004 Nissan Murano key fob combines keyless entry and remote start functionality. It transmits radio signals to your vehicle, allowing you to lock/unlock doors, open the trunk, and even start the engine remotely. Knowing how these signals work and the different types of key fobs available is crucial for proper maintenance and replacement.

Types of 04 Nissan Murano Key Fobs

There are typically two main types of key fobs for the 2004 Nissan Murano: the standard key fob with integrated key and the smart key fob. The standard key fob needs to be physically inserted into the ignition, while the smart key fob allows for keyless ignition.

How Does the 04 Nissan Murano Key Fob Work?

The key fob uses radio frequency identification (RFID) to communicate with your Murano. When you press a button, the fob transmits a unique coded signal to the receiver in your car.
