Key Fob Battery Lifespan: What to Expect

The average key fob battery lasts between 3 and 4 years. However, several factors can influence this timeframe. Factors like usage frequency, climate, and the quality of the battery itself can impact how long your key fob battery lasts. High usage, extreme temperatures, and cheaper batteries can shorten lifespan significantly. Conversely, less frequent use, moderate climates, and higher-quality batteries can extend the life of your key fob.

Signs Your Key Fob Battery is Dying

Intermittent function: The key fob may work sometimes and not others, leading to frustrating inconsistencies.
Dimming key fob lights: If your key fob has an LED light, it may appear dimmer than usual.
Slow response: The car may take longer to respond to the key fob commands.

If you experience any of these issues, it’s a strong indication that your key fob battery needs replacing soon. Don’t wait until it dies completely.
