Today, newer vehicles are equipped with key fobs that allow you to lock and unlock your Subaru without physically inserting a key into the door. This feature is especially helpful when you have your hands full or are in a hurry, but what happens if it stops working?
There are some things you can do to troubleshoot this problem yourself and try to fix it at home before taking it in for service. One common issue that can occur is a low battery in the key fob. When this happens, you’ll likely see one of the following messages on your dashboard:
- “Key Fob Battery Low”
- “Keyless Remote Entry Not Working”
- “Subaru Access Key Battery Low”
If you see one of these messages, it typically indicates that the key fob’s battery is critically low and needs to be replaced as soon as possible. If you’re experiencing this message, make sure to replace the key fob’s battery as soon as possible to avoid any inconvenience or potential security risks. You can usually find replacement batteries at a local hardware store or automotive shop.
If replacing the battery doesn’t fix the problem, there may be something else wrong with your key fob, and it will need to be serviced. You can bring it to a service center or Subaru dealership to have it looked at.
What happens when the key fob battery is low?
When the battery in your key fob is low or starts to die, you will likely start to notice some problems. Some of the things you might notice are:
- The most common symptom of a Subaru access key low battery is that the key will not work properly. You may have tried to press the buttons multiple times, but nothing happens after these attempts.
- You may also notice that the key is not locking or unlocking doors when you press the button on the remote. This usually happens if there are some bad connections between your car and its key fob.
- The key fob sends a signal to the car that allows you to start the engine. If the battery is low, that signal may not be strong enough to reach the car’s computer, and the car will not start.
How do I change the battery in my Subaru key?
When replacing the battery, you should always replace it with a new one. If you don’t have any spare batteries available, then you can buy them online or at your local hardware store. They are usually sold by size and type, so make sure to check the specifications before buying anything.
To install a replacement battery in your Subaru key fob, you should follow the instructions that came with it. This will help ensure that everything goes smoothly and there is no chance of damaging anything in your key fob.
Here’s a generic guide on how to change the battery in your Subaru key fob:
- To change the battery, you’ll need to remove the back cover of the key fob. There’s usually a small recess or notch in the cover that can be used as a finger grip to pry it off.
- Once the cover is off, you’ll see the battery attached to a small circuit board. To remove the battery, gently pry it away from the circuit board with a small flathead screwdriver.
- When putting in the new battery, make sure that positive and negative sides are facing correctly and that it’s tightly secured in place.
- Replace the back cover of the key fob and give it a gentle snap to secure it in place.
- Test the key fob by pressing the power button. If it works, then congratulations! You’ve successfully replaced the battery in your Subaru key fob. If not, then you may have installed it incorrectly and will need to try again.
What battery does my Subaru key take?
The battery in your Subaru key fob likely takes a CR2032 battery. This is a common battery type that is used in many small electronic devices. You should be able to find this battery at most convenience stores or electronic stores. If you are unable to find the CR2032 battery, you may also be able to use a CR2016 or CR2025 battery.
When it comes to purchasing batteries, be sure to get an authentic battery. There are many counterfeit batteries on the market, and they may not work in your key fob or even damage your key fob in the long run. Knock off batteries may be difficult to identify, but here are some telltale signs of a counterfeit CR2032 battery for your information:
- The battery is significantly lighter in weight than an original CR2032 battery.
- The battery has a different shape or size than an authentic CR2032 battery.
- The printing on the battery is fuzzy or unclear.
- The packaging looks different from the original CR2032 batteries.
- There is no holographic sticker on the packaging.
- The price is lower than what you would expect to pay for a CR2032 battery.
These are some tips to help you identify a counterfeit battery, but if you are still unsure whether or not the battery is authentic, it is best to purchase the battery from a reputable source.
In conclusion, the battery is essential to your Subaru key fob. Without the battery, you will not be able to use the car remote or push-button starter on your vehicle.
If you are noticing that your battery is weak and needs replacing, it is time to replace it with a fresh CR2032 battery right away. This will ensure that you have a working key fob when you need it and will help prevent any unexpected problems from happening.
