It’s a common question for vehicle owners: “How long do key fob batteries last?” and “Will my car tell me when the key fob battery is low?”. For BMW owners, understanding the lifespan of your key fob battery and the warning signs is essential for uninterrupted vehicle access. Let’s delve into what you can expect regarding your key fob battery.
Several factors can influence the lifespan of your key fob battery. Extreme temperatures, whether scorching heat or freezing cold, can negatively impact battery life, even when the fob isn’t in active use. Usage frequency also plays a significant role. Frequent use naturally drains the battery faster. Furthermore, unintentionally pressing buttons while the fob is in your pocket or bag can unnecessarily deplete the battery.
Fortunately, BMW vehicles are equipped with systems to alert you when your key fob battery is running low. Since the 1990s, BMW has incorporated low battery indicators into their vehicles. Older models, like the e38 and e39, displayed a “check control” message when the remote key’s replaceable battery was getting weak. Even newer models, such as the f06 6 Series and f15 X5, continue this trend, alerting drivers through the check control system when a battery replacement is needed. One owner reported their 2013 BMW 6 Series key fob battery lasted a solid 8 years before requiring replacement, showcasing a typical lifespan under normal conditions.
Experiencing a “My Key Fob Battery Is Low” warning in your BMW is usually a straightforward indication to replace the battery. These systems are designed to provide ample warning, preventing you from being stranded due to a dead key fob battery. Keep an eye out for these messages on your dashboard to ensure seamless access to your vehicle.
