As a car owner, there’s nothing more frustrating than realizing your key fob has stopped working, leaving you stranded and unable to access your vehicle. In most cases, the culprit behind a non-responsive key fob is a dead battery. Fortunately, replacing the battery is a relatively simple process that can be done at home with a few basic tools. In this article, we’ll walk you through the steps to replace your key fob battery, so you can get back on the road in no time.
Understanding Key Fob Batteries
Before we dive into the replacement process, it’s essential to understand the type of battery used in your key fob. Most key fobs use a small, coin-shaped battery, such as a CR2032 or CR2025. These batteries are designed to provide a long lifespan, typically lasting between 2-5 years, depending on usage. However, the battery life can vary depending on factors such as the quality of the battery, the frequency of use, and the environmental conditions.
Identifying the Battery Type
To replace the battery, you need to identify the type of battery used in your key fob. You can usually find this information in your vehicle’s owner’s manual or on the key fob itself. Look for a small label or imprint on the back or bottom of the key fob that indicates the battery type. If you’re still unsure, you can consult with a dealership or a locksmith who can help you determine the correct battery type.
Purchasing a Replacement Battery
Once you’ve identified the battery type, you can purchase a replacement battery at most electronics stores, hardware stores, or online marketplaces. Make sure to buy a high-quality battery that meets the specifications of your key fob. A good quality battery will provide a longer lifespan and ensure that your key fob functions reliably.
Replacing the Key Fob Battery
Now that you have the replacement battery, it’s time to replace the old one. The process is relatively simple and requires only a few basic tools. Here’s a step-by-step guide to help you replace the key fob battery:
Preparing the Key Fob
Before you start, make sure you have a flat surface to work on and that your key fob is clean and dry. Remove any attachments or accessories from the key fob, such as a key ring or charm. This will give you clear access to the battery compartment.
Opening the Battery Compartment
The battery compartment is usually located on the back or bottom of the key fob. Look for a small screw or clip that holds the compartment in place. Use a small screwdriver or a flathead screwdriver to remove the screw or clip. Be careful not to damage the surrounding plastic or electronic components.
Removing the Old Battery
Once you’ve opened the battery compartment, you’ll see the old battery. Gently pull out the old battery, taking care not to touch any of the electrical components. If the battery is stuck, you can use a small pair of tweezers to carefully pry it out.
Installing the New Battery
Take the new battery and insert it into the battery compartment, making sure it’s securely seated. Pay attention to the polarity of the battery, ensuring that the positive terminal is facing up. If you’re unsure, consult the owner’s manual or the manufacturer’s instructions.
Closing the Battery Compartment
Once the new battery is in place, close the battery compartment and replace the screw or clip. Make sure it’s securely fastened to prevent the battery from coming loose.
Troubleshooting Common Issues
If your key fob is still not working after replacing the battery, there may be other issues at play. Here are a few common problems and their solutions:
- If your key fob is not responding at all, try resetting it by pressing the locking and unlocking buttons simultaneously for 10 seconds.
- If your key fob is only working intermittently, try cleaning the battery contacts and ensuring that the battery is properly seated.
Preventing Future Battery Drain
To extend the life of your new battery, make sure to store your key fob in a dry and cool place, away from direct sunlight and extreme temperatures. Avoid exposing your key fob to water or moisture, as this can damage the electronic components. Additionally, try to minimize the use of your key fob, as excessive use can drain the battery faster.
Conclusion
Replacing your key fob battery is a relatively simple process that can be done at home with a few basic tools. By following the steps outlined in this article, you can get back on the road in no time. Remember to always use high-quality batteries and to take care of your key fob to prevent future problems. If you’re still unsure or encounter any issues, don’t hesitate to consult with a dealership or a locksmith for assistance.

How often do I need to replace the battery in my key fob?
The frequency with which you need to replace the battery in your key fob depends on several factors, including the type of battery used, how often you use the key fob, and the conditions in which you store it. On average, a key fob battery can last for around 2-5 years, but this can vary significantly. If you use your key fob frequently, you may need to replace the battery more often, while infrequent use can help to extend the battery’s lifespan. It’s also important to note that some key fobs use more advanced batteries that can last longer than traditional batteries.
To extend the life of your key fob battery, it’s a good idea to store it in a cool, dry place when not in use, and to avoid exposing it to extreme temperatures or moisture.

What type of battery does my key fob use?
The type of battery used in your key fob depends on the make and model of your vehicle, as well as the type of key fob you have. Most key fobs use a small, coin-shaped battery, such as a CR2032 or CR2025, which are commonly available at most hardware stores or online. Some key fobs may use a different type of battery, such as a CR1620 or CR1632, so it’s a good idea to consult your vehicle’s owner’s manual or the manufacturer’s website to determine the correct type of battery for your key fob.
To find the correct type of battery for your key fob, you can also check the back or bottom of the key fob for a label or stamp that indicates the battery type. You can also search online for the make and model of your vehicle, along with the words “key fob battery,” to find information on the correct type of battery to use.

How do I replace the battery in my key fob?
Replacing the battery in your key fob is a relatively simple process that you can do yourself with a few basic tools. The first step is to purchase a replacement battery of the correct type, which can be found at most hardware stores or online. Next, you’ll need to open the key fob by sliding open the back or removing a small screw, depending on the type of key fob you have.

Can I use a rechargeable battery in my key fob?
While it may be tempting to use a rechargeable battery in your key fob, it’s generally not recommended. Most key fobs are designed to work with disposable batteries, and using a rechargeable battery can cause problems with the key fob’s performance and reliability. Rechargeable batteries can also be more prone to leakage and corrosion, which can damage the key fob’s electronic components and render it useless.
If you’re looking for a more environmentally friendly option, you may consider using a battery with a longer lifespan, such as a lithium battery, which can provide reliable service for up to 5 years or more. You can also consider purchasing a key fob with a more efficient design that uses less power and can extend the life of the battery. Be sure to consult your vehicle’s owner’s manual or the manufacturer’s website to determine the best type of battery to use in your key fob and to ensure that you’re using a battery that is compatible with your vehicle’s systems.

When disposing of your old key fob battery, it’s essential to do so in an environmentally responsible manner. Most communities have designated facilities for recycling batteries, and you can check with your local waste management agency to find out where to take your old battery. You can also check with local retailers, such as hardware stores or home improvement centers, to see if they have a battery recycling program in place.
When recycling your old battery, be sure to follow any guidelines or regulations provided by the recycling facility or retailer. You may need to tape the terminal ends of the battery to prevent them from coming into contact with other metals and causing a fire. You can also consider donating your old battery to a local school or community group that may be able to use it for educational or other purposes. By recycling your old battery, you can help to reduce waste and minimize the environmental impact of your key fob.
