Replacing a Nissan key fob battery is a simple task that takes only a few minutes. A key fob battery that is low will cause the key fob to not work properly, or at all. If you are having trouble unlocking your Nissan, or if the key fob is not working properly, it may be time to replace the battery.
Replacing the key fob battery on your Nissan can save you time and money compared to having to call a locksmith or go to the dealership. Replacing the battery yourself may also void any warranties on the key fob, so it is important to weigh the pros and cons before attempting this repair yourself.
