Advanced Key Fob Features and Battery Consumption: Subaru Key Fob Battery
Advanced key fob features such as remote start and proximity unlocking offer convenience but can impact battery life. Understanding how these features affect battery usage and optimizing their use can extend the lifespan of your key fob battery.
Conserving Battery Power with Advanced Features
* Remote Start:While convenient, remote start significantly drains the battery. Limit its use to necessary situations, such as warming up your car on cold mornings or cooling it down on hot days.
Proximity Unlocking
This feature constantly scans for the key fob’s presence, which can drain the battery. Disable it if you’re not using it or in areas with high signal interference.
Keyless Entry
Use the physical key instead of the key fob for short trips or when the battery is low. This reduces the need for the key fob to transmit signals.
Additional Tips for Extended Battery Life
* Avoid Extreme Temperatures:Store your key fob in moderate temperatures. Extreme heat or cold can damage the battery.
Keep it Dry
Moisture can damage the battery and electronic components. Protect your key fob from water or excessive humidity.
Change Battery Regularly
Replace the key fob battery every 1-2 years or as recommended by the manufacturer. This ensures optimal performance and prevents unexpected battery failures.
