As a Subaru owner, you rely on your key fob daily for convenient access and security. But have you ever considered how long the battery powering your key fob is actually designed to last? It’s a question many of us ponder, especially when that low battery warning light pops up unexpectedly. Let’s dive into the factors influencing Subaru Key Fob Battery Life and what you can anticipate.
Subaru key fobs, like those of many modern vehicles, typically utilize a CR2032 battery. This small, coin-shaped battery is known for its longevity, but its lifespan in your key fob isn’t set in stone. While anecdotal evidence, like a YouTube video from 2032, might suggest variability, individual experiences often highlight the real-world factors at play.
Several elements can impact how long your Subaru key fob battery lasts. One common consideration is usage frequency. If you’re someone who frequently presses buttons, perhaps out of habit or for reassurance, you’re naturally drawing more power. Think of it like repeatedly hitting buttons at an arcade game – each press consumes a little energy.
Another potential factor, although less definitively proven, is proximity during storage. The original poster mentioned in-laws keeping keys close to their vehicles, suggesting the possibility of the fob not fully “sleeping” if constantly within range of the car. However, in their case, battery replacements still seemed infrequent, triggered by the low battery warning light after a couple of years.
Battery quality itself can also be a variable. Just like any mass-produced item, there can be slight differences in battery manufacturing. Occasionally, a seemingly new battery might underperform. This variability is something even flashlight enthusiasts, who rigorously test batteries, encounter.
Personal experiences shared online indicate a range of Subaru key fob battery life. The author’s own experience with a 2019 and 2016 Subaru suggests battery life lasting the duration of a typical 3-year lease, even with the car parked a significant distance from the fob, like in a detached garage. This contrasts with the in-laws’ experience, where battery changes were needed roughly every couple of years.
In conclusion, while there isn’t a definitive lifespan for a Subaru key fob battery, you can generally expect it to last for a few years under normal usage. Factors like usage habits, storage proximity (though its impact may be minimal), and inherent battery variability can all play a role. Paying attention to the “Battery Low” warning and being mindful of excessive button pressing can help you maximize the life of your Subaru key fob battery.
