What's A Key Fob And Why Is It Important?
Metal keys were once the primary means of unlocking and starting a car. Some cars had a separate key for the doors and the ignition, while others had a single key for both. Then, somewhere in the 1980's, along came remote entry fobs.
Remote key fobs allow wireless control of car functions using radio signals. Key fobs for unlocking car doors first appeared in the '80s and became common place by the mid-'90s. Some Nissan steering columns are designed in a way that they will not even unlock unless the fob is detected (read more about that here.) As technology has progressed, key fobs have become more sophisticated in their functionality and security.
The Importance Of Key Fobs

Most modern Nissan vehicles cannot function without a key fob. That's why it's important to take care of your key fob and ensure it's in good shape. To be avoid any fob-related problems, be sure to:
- Change the battery at the first sign of unresponsive fob buttons.
- Keep your fob clean and moisture-free (as you would any electronic component.)
- Keep your spare key fob in a safe place, and check/replace battery regularly.
The Functions Of Key Fobs
When first introduced, key fobs had very simple functionality. They could unlock the car doors, open the trunk, or sound the horn if you couldn't remember where you parked. As technology progressed, key fobs became much more complex and capable. Some automakers even integrated the physical car key into the fob, which would pop out like a switchblade and served as a backup entry method should the key fob fail.
Proximity key fobs were available by the early 2000s. This technology allows the car doors to unlock without taking the fob out of your pocket or pressing a button. A control module inside the car senses the presence of the key fob by radio frequency and opens the doors automatically.
By the late 2000s, carmakers were introducing remote start capability. This allows the vehicle to be started remotely with a press of a key fob button. By the 2010s, automakers were removing physical keys from vehicles altogether. Push button start uses the proximity of the keyfob to authorize starting the vehicle without needing a physical key. Today, fobs and keys have become one.
The Security Of Key Fobs
Now that key fobs can do so many things to control your vehicle, what about security? Modern key fobs operate with Radio Frequency Identification (RFID) technology. This functions like a unique radio frequency "barcode" that ensures a secure connection between the vehicle and the key fob.
RFID is a secure way to pair a key fob with a car's onboard control module. However, carmakers are adding more hardware and software security that prevents thieves from intercepting and copying your key fob information. This is critical for modern cars, given that key fobs now have complete control over unlocking and starting vehicles.
