What Kind of Batteries Are Used in Infiniti Key Fob?

Knowing what kind of batteries are used in your Infiniti key fob can save you time, money, and frustration. A dead key fob battery can leave you stranded, so understanding how to replace it is crucial. This comprehensive guide dives deep into the world of Infiniti key fob batteries, covering everything from the specific battery types to step-by-step replacement instructions.

Decoding Your Infiniti Key Fob Battery

Infiniti key fobs typically use CR2032 or CR2025 batteries. These are small, circular, lithium button cell batteries commonly found in electronics. The specific type for your Infiniti will depend on the model and year. Checking your owner’s manual is the most reliable way to confirm the correct battery type. You can also often find this information on the back of the key fob itself, sometimes hidden beneath a small cover.

Identifying the CR2032 and CR2025 Batteries

Both CR2032 and CR2025 batteries are 3V lithium cells, but the “2032” and “2025” refer to their dimensions. The CR2032 is slightly thicker (3.2mm) than the CR2025 (2.5mm). While they are often interchangeable, using the correct battery ensures optimal performance and prevents potential issues.
