Why is My Nissan Key Fob Not Working?
Several reasons can contribute to a Nissan key fob malfunction. These range from simple issues like a dead battery to more complex problems requiring professional help. Let’s explore some of the most common culprits:

Reprogramming the key fob may be necessary to restore its functionality.

Key Fob Damage
Physical damage to the key fob, such as a cracked casing or damaged internal components, can prevent it from working correctly. Dropping the key fob or exposing it to moisture can cause such damage.
Car Battery Issues
Believe it or not, a weak or dead car battery can also interfere with the key fob’s ability to unlock the car. The fob relies on the car’s electrical system to function, so a faulty car battery can disrupt this communication.
