The average lifespan of a Tesla key fob battery varies depending on usage and environmental factors. On average, a Tesla key fob battery can last anywhere from 1 to 2 years, with some owners reporting up to 3 years of use before needing a replacement. However, if you use your key fob frequently or live in an area with extreme temperatures, you may need to replace the battery more often.
Signs That Indicate the Need for Replacement
There are several signs that indicate the need to replace your Tesla key fob battery. These include:
- Weak or intermittent signal: If your key fob is having trouble communicating with your vehicle, it may be a sign that the battery is weakening.
