The answer to this question is that the battery life of a Subaru key fob will vary depending on the model and year of the key fob.

How Long Does The Average Subaru Key Fob Battery Last?

is a question we get all the time here at YourMechanic. We decided to ask our expert mechanics to help answer this question for all our Subaru-driving readers out there.

The average key fob battery lasts between 2 and 5 years, depending on the brand of battery and how often you use your key fob. If you use your key fob regularly (i.e. to unlock your car doors or start your car engine), then you can expect the battery to last on the lower end of the spectrum. Conversely, if you only use your key fob occasionally, then you can expect the battery to last on the higher end of the spectrum.

There are a few things you can do to extend the life of your key fob battery, such as:

– Avoid exposing the key fob to extreme temperatures (i.e. hot or cold).

– Remove the key fob from your key ring when you’re not using it.

– Store the key fob in a cool, dry place.

– Avoid dropping or banging the key fob.

If you notice that your key fob isn’t working as well as it used to (i.e. the range is shorter or the buttons are less responsive), then it’s probably time to replace the battery. Luckily, this is a relatively simple and inexpensive process that you can do yourself at home.

What Is The Average Lifespan Of A Subaru Key Fob Battery?

This is a question that we get fairly often here at the dealership. The answer, unfortunately, is not as cut and dry as we would like it to be. Subaru key fob batteries can last anywhere from a couple of years to upwards of five years, depending on a variety of factors.

So, what determines how long a Subaru key fob battery will last? First, it depends on the type of battery that is used in the key fob. There are two common types of batteries used in key fobs: CR2032 and CR2025. The CR2032 batteries are slightly larger in size and tend to have a longer lifespan than the CR2025 batteries.

Another factor that can affect the lifespan of a Subaru key fob battery is how often the key fob is used. If you are someone who uses their key fob multiple times throughout the day, the battery is going to drain quicker than someone who only uses it occasionally. Additionally, if you live in a warmer climate, the heat can also shorten the lifespan of the battery.

If you are looking to extend the lifespan of your Subaru key fob battery, there are a few things that you can do. First, try to avoid exposing the key fob to extreme temperatures, both hot and cold. Also, if you are not using the key fob for an extended period of time, it is a good idea to remove the battery. This will prevent the battery from slowly draining over time.

If you find that your Subaru key fob battery is starting to die prematurely, there are a few things that you can do to try and revive it. First, try removing the battery and then re-inserting it. Sometimes, this can reset the key fob and help the battery to last longer. If that doesn’t work, you can try replacing the battery with a new one.

Will My Subaru Key Fob Work If The Battery Is Low?

If you’re like most people, you probably don’t think much about your car key fob until it stops working. If your Subaru key fob does stop working, it’s probably because the battery is low.

Although it’s not impossible for the key fob to stop working for other reasons, a low battery is the most likely culprit. If your key fob is more than a few years old, the battery may simply be worn out and need to be replaced.

If you have a newer key fob, the battery may just need to be recharged. You can do this by placing the key fob in a bowl of rice overnight. The rice will absorb the moisture from the battery and help to recharge it.
