    How to Replace the Battery in your Jeep Wrangler JK Key Fob

    This is a question that we get all the time here at Jeep Compass Forum, and its one that weve been trying to answer for a while now. The average lifespan of a Jeep Compass key fob battery is about two years. However, there are a few things that can affect this number.

    First, lets talk about what a key fob battery is and what it does. A key fob battery is a small, lithium ion battery that is used to power your Jeep Compass key fob. This battery is what allows you to remotely unlock your doors, start your engine, and do other cool Jeep Compass features.

    Now, the lifespan of your key fob battery will depend on a few factors. First, how often do you use your key fob? If you use it multiple times a day, then your battery will obviously die faster than someone who only uses it once a week.

    Another factor that can affect the lifespan of your key fob battery is the temperature. If you live in a cold climate, your battery will die faster than someone who lives in a warm climate. This is because cold temperatures cause the battery to lose power faster.

    Finally, the type of battery you have in your key fob can also affect its lifespan. There are two different types of batteries that are commonly used in key fobs: CR2032 and CR2025. The CR2032 battery is the newer of the two and it has a longer lifespan than the CR2025 battery.

    So, if you want your key fob battery to last as long as possible, use it sparingly and keep it in a warm place.
