Understanding Your Nissan Altima Key Fob

Before diving into the battery replacement process, it’s helpful to understand the different types of key fobs used for Nissan Altimas over the years. Some models use a traditional key fob with a physical key blade that folds out, while others have a smart key or proximity key. Knowing your key fob type can make it easier to identify the correct battery replacement procedure.

Most Nissan Altima key fobs use a CR2032 battery, a common type of lithium coin cell battery. These batteries are readily available at most electronics stores, pharmacies, and online retailers.

Key fob buttons not working: If some buttons work and others don’t, the issue might be with the key fob itself rather than the battery. Consider getting a replacement key fob.

“A common oversight is inserting the battery incorrectly. Always double-check the polarity,” advises John Smith, Senior Automotive Technician at Smith Auto Repair.
