You rely on your Tesla Model S key fob every day, and the last thing you want is to be stranded with a dead battery. But just how long does a key fob battery last in a Model S?
While there isn’t a one-size-fits-all answer, we’ll break down the factors affecting battery life, common signs of a dying battery, and how to replace it yourself. Let’s dive in!
Factors Affecting Tesla Model S Key Fob Battery Life
Several factors can impact how long your Model S key fob battery lasts:
- Frequency of Use: Just like your car battery, your key fob battery drains a little with each use. Frequently unlocking, locking, and summoning your car will lead to faster battery depletion.
- Signal Strength: If you frequently park far from your car or in areas with signal interference, the key fob works harder to communicate, draining the battery quicker.
- Battery Quality: Like all batteries, quality varies. A high-quality battery from a reputable brand will generally last longer than a cheaper alternative.
- Temperature Extremes: Extreme heat or cold can impact battery performance and lifespan.
How to Know When Your Model S Key Fob Battery is Dying
Before your key fob battery leaves you stranded, your Model S will typically provide warnings on the touchscreen. You might also notice:
- Decreased Range: A weak battery might struggle to communicate from a distance, forcing you closer to the car to lock, unlock, or start it.
- Intermittent Functionality: The key fob might work intermittently, requiring multiple button presses or only working at close range.
- Warning Messages: Your Model S touchscreen might display messages like “Key Fob Battery Low” or “Replace Key Fob Battery”.
