Replacing the battery in a Subaru key fob is a simple task that can be completed in just a few minutes. The battery powers the key fob’s electronic components, such as the buttons and the transponder chip. If the battery is low, the key fob may not work properly. The tools you will need to replace the battery are a small screwdriver or a coin, a new battery, and the key fob.
The Unsung Hero: Why Your Subaru Key Fob Deserves Some Love
You might not think much about your Subaru key fob on a daily basis, but trust us, it’s a real MVP in your automotive life. It’s not just a fancy key; it’s your gatekeeper to convenience, security, and remote control of your trusty Subaru.
Picture this: You’re walking up to your car on a rainy day. Instead of fumbling with keys and getting drenched, you simply reach for your key fob and press the “unlock” button. Poof! Your car magically unlocks, offering you a warm and dry sanctuary. That’s the power of a working key fob, folks.
But here’s the catch: if your key fob battery decides to take a siesta, you’re in for a world of inconvenience. No more keyless entry, no more remote start (if you’re the lucky owner of a Subaru with this feature), and no more feeling like you’re living in the future. It’s like your car has reverted back to the Stone Age, only with more gadgets.
Identifying a Dead Key Fob Battery: The Subtle Clues
Your Subaru key fob is your trusty sidekick, the magical device that unlocks your car and sets off a symphony of beeps as you search for it in your bag. But what happens when your key fob starts acting up, like a grumpy old man refusing to cooperate? Chances are, it’s time to swap out that dead battery.
The Signs: Small Annoyances That Add Up
The first thing you might notice is that the buttons aren’t as responsive as they used to be. They might require an extra press or two, or they might not work at all. It’s like trying to have a conversation with someone who’s half asleep and hard of hearing.
Another dead battery symptom is when the range gets shorter. You used to be able to unlock your car from across the street, but now you have to be practically touching it. It’s like your key fob has lost its super strength and can only project its signal a few feet away.
Lastly, the lights might be dimmer or flickering. This is a clear indication that the battery is on its last legs, like a candle about to burn out.
Don’t Ignore It: The Importance of a Working Fob
Ignoring a dead key fob battery is like ignoring a leaky faucet – it’s a problem that will only get worse over time. A dead battery can lead to:
- Being locked out of your car in the pouring rain or freezing cold
- Feeling like a clueless newbie when you have to use the actual key to unlock your car
- Missing out on the convenience of keyless entry and remote start
So, the next time your key fob starts acting up, don’t hesitate to pop in a new battery. Your car, and your sanity, will thank you for it.

When it comes to replacing your Subaru key fob battery, safety first! Picture this: you’re all set to give your fob a new lease on life, but you forget to wear gloves and accidentally touch the positive and negative terminals together. ZAP! You’re left seeing stars and wondering what happened.
To avoid such mishaps, it’s crucial to follow these safety precautions:
- Don gloves like a pro: Trust me, those latex gloves aren’t just for doctors. They’ll protect your delicate fingers from any potential electrical shocks.
- Avoid short circuits at all costs: Remember that dreaded ZAP? Don’t let it happen to you! Keep the battery terminals separated and away from any metal objects that could create a short circuit.
- Disconnect the battery: Before you start tinkering with anything, disconnect the old battery. This will ensure that no stray electricity finds its way into your key fob.
- Handle the battery with care: Batteries can be delicate little things. Avoid dropping or bending them. Instead, treat them with the utmost tenderness and respect.

The CR2025 battery provides reliable and long-lasting power for key fob operations. Its compact size ensures a snug fit within the key fob casing, maintaining stable electrical contact.
