When to change battery in Nissan key fob?
The Nissan key fob battery is solidly built to provide long-lasting performance and operation.
However, like every battery, it will wear out someday once it reaches the expected lifespan or time limit.
To prevent being locked out of your car and avoid other related issues that may arise due to an unresponsive key fob, it is very crucial that you know the signs/symptoms of a bad key fob battery.
These symptoms serve as a reminder, telling you that it’s time to get a new battery installed in your key fob for continued & reliable operation and performance.
When do you experience a drop in signal strength?

This could extend up to about 40 feet in most cases.
When your key fob is in good working condition, you can easily start your engine, unlock & lock your car while a few feet away from it.
However, when the battery begins to wear out or lose its power, this results in a drop in the signal strength.
During this time, you will notice that the key fob won’t activate or process your desired command until you move very close to your vehicle.
This indicates that the fob’s battery is running weak and needs to be replaced immediately to continue enjoying a top performance.

Usually, a key fob in good condition should lock and unlock your vehicle’s doors instantly when you click on the command button once.
If you realize that your command is activated only after multiple clicks on the button or after several attempts.
This is a sign informing you about the current state of the battery. You will have to get the bad/failing battery removed and replaced with a new unit.
Inconsistency in operation & performance
One moment, the initiated command activates or clicks correctly or as expected. On the next attempt, especially with a similar function and within a similar range, you may experience a change in performance.
When you notice that the Fob’s key performance fluctuates or fails to perform on a top-level consistently, you may need to get the fob’s battery replaced.
