What Type of Battery Does a Key Fob Take?
If you own a car with keyless entry, chances are you have a key fob. These small, handheld devices provide convenient access to your vehicle, allowing you to lock and unlock the doors with just a push of a button. But have you ever wondered what type of battery powers these handy devices? In this article, we will explore the different types of key fob batteries, their specifications, and how to replace them when needed.
The Importance of a Key Fob Battery
Before we dive into the different types of key fob batteries, let’s first understand the importance of a properly functioning battery for your key fob. The key fob battery is what gives life to your device, enabling it to send signals to your car’s central locking system.
A key fob with a weak or dead battery can cause inconvenience and frustration. Imagine being unable to unlock your car remotely or having to manually insert the key into the lock every time you want to gain access. Therefore, it is crucial to ensure your key fob battery is in good condition. Let’s explore the various types of batteries commonly used in key fobs.
1. CR2032
One of the most commonly used batteries in key fobs is the CR2032. This coin-shaped battery is widely available and suitable for a range of electronic devices. Its compact size and 3-volt capacity make it ideal for powering key fobs.
The CR2032 battery is also known for its long shelf life, which means it can be stored for extended periods without significant degradation. This is particularly useful if you keep spare batteries on hand or purchase them in bulk. Replacing the battery in your key fob with a CR2032 is a simple and cost-effective solution.
2. CR2025
Another type of battery often found in key fobs is the CR2025. Similar to the CR2032, the CR2025 is a coin cell battery with a 3-volt capacity. It is slightly thinner than the CR2032 but has a larger diameter. The CR2025 is also widely available and compatible with various electronic devices.
While the CR2025 may not be as common as the CR2032, it is still a reliable choice for powering your key fob. If you’re unsure which battery your key fob requires, consult your car’s manual or consult a professional to ensure you choose the correct replacement.
3. CR2016
The CR2016 is another type of coin cell battery that is occasionally used in key fobs. It has a lower capacity of 3 volts, making it suitable for devices with lower power requirements. While the CR2016 is less common, it is still important to be aware of its existence, as some key fobs may require this specific battery.
If your key fob uses a CR2016 battery, it is essential to have the correct replacement on hand when the time comes to change it. Always double-check your car’s manual or consult a professional to be certain of the correct battery type for your key fob.
Replacing Your Key Fob Battery
Now that we have explored the different types of batteries, let’s discuss how to replace the battery in your key fob. It’s important to note that the process may vary slightly depending on the make and model of your key fob, so always refer to your car’s manual for specific instructions. However, these general steps should give you a good idea of what to expect.
Step 1: Identify the Battery Compartment
Begin by locating the battery compartment on your key fob. This is usually located on the back or side of the device and may be covered by a small panel or screw. Use a small screwdriver or a coin to remove the cover and access the battery compartment.
Step 2: Remove the Old Battery
Once you have access to the battery compartment, carefully remove the old battery. Some key fobs may have a small clip or spring that needs to be pushed or lifted to release the battery. Pay attention to the orientation of the battery as you remove it, as this will help you correctly insert the new one.
Step 3: Insert the New Battery
Take your new battery, ensuring it is the correct type and orientation. Carefully insert it into the battery compartment, making sure it fits snugly and securely. Take care not to touch the battery terminals with your fingers, as the oils from your skin can affect its performance.
Step 4: Reassemble the Key Fob
With the new battery in place, reassemble the key fob by replacing the battery cover or screw. Make sure it is tightly secured to prevent any damage or accidental opening of the battery compartment.
Step 5: Test the Key Fob
Once the key fob is reassembled, it’s time to test it. Stand near your car and press the buttons on the key fob to ensure it is working correctly. If your car locks and unlocks as expected, congratulations! You have successfully replaced the battery in your key fob.
In conclusion, the type of battery your key fob takes depends on the specific make and model of your device. However, the most common types are CR2032, CR2025, and occasionally CR2016. It is important to identify the correct battery type to ensure your key fob functions properly.
Remember, always consult your car’s manual or seek professional assistance if you are unsure about the battery type or the replacement process. By keeping your key fob battery in good condition and replacing it when necessary, you can continue to enjoy the convenience of keyless entry for your vehicle.
