We’ll answer some of the most commonly asked questions about key fob battery replacement. So, whether you want to know what kind of battery your key fob takes, if you can start your car with a dead fob, or if you need to reprogram it after changing the battery, we’ve got you covered. Let’s get started.
Introduction
Modern cars often come with key fobs that operate as remote controls for locking, unlocking, and starting your vehicle. These key fobs usually run on batteries that can become drained over time. When this happens, you may need to replace the battery to continue using your key fob. We will discuss how to replace the battery in a key fob and answer some commonly asked questions regarding key fob batteries.
Step 1: Determine the type of battery your key fob uses. To do this, you will need to open the key fob and check the type of battery installed. Most key fobs use small coin or button batteries, such as CR2032, CR2025, or CR2016.
Step 2: Remove the old battery from the key fob. You can use a small screwdriver or key fob tool to carefully pry open the key fob casing. Then, gently remove the old battery from its slot. Be sure to take note of the orientation of the battery before removing it, so you can insert the new battery correctly.
Step 3: Install the new battery. Take the new battery and insert it into the slot in the same orientation as the old battery. Then, push down gently until the battery snaps into place. Make sure the battery is securely in place before closing the key fob casing.
If you are unsure about how to replace the battery in your key fob, you can refer to the user manual that came with your car. Additionally, some car dealerships and locksmiths may offer key fob battery replacement services.

Can I Start My Car With a Dead Key Fob?
Key fobs have become an essential component for modern car keys. It offers convenience and safety, allowing the driver to lock or unlock the doors and even start the car with just a push of a button. However, like any other electronic devices, key fobs also have their own limits. One of the most common problems is a dead key fob battery. But the big question is, can you still start your car with a dead key fob?
The answer is yes, and no. It depends on the car make and model, as well as the type of key fob. Most modern cars cannot start without a functioning key fob. The key fob communicates with the car’s computer system, allowing it to start the engine. Without it, the car will not crank and start even if you have the physical key.
On the other hand, some older cars that use a traditional mechanical key can start the engine even with a dead key fob battery. You just need to insert the physical key into the ignition and turn it like you would normally do. However, this will not work for newer models that have keyless ignition systems.
- So, what should you do if you have a dead key fob battery and need to start your car?
- First, check your car’s manual or contact your dealer to see if your car has a traditional mechanical key and how to use it to start the engine.
- If you have a newer car with keyless ignition, you can try holding the key fob close to the start button or inserting it into a designated slot. Sometimes, this can still work even with a dead battery.
- If none of the above works, your only option is to replace the dead key fob battery or call a professional for assistance.
Do I Need to Reprogram My Key Fob After Changing the Battery?

How Long Do Key Fob Batteries Last?
As convenient as they may be, key fobs can become quite an inconvenience when their batteries die out. It’s important to know how long key fob batteries last so that you can take necessary precautions to avoid being stranded at an inconvenient time.
On average, key fob batteries last between 2-3 years. However, this can vary depending on usage and the type of battery used. For instance, lithium-ion batteries tend to last longer than alkaline batteries.
- One factor that can cause a battery to drain faster is exposure to extreme temperatures.
- Another factor that affects battery life is how often you use the key fob.
- If you frequently use it to lock and unlock your vehicle, the battery may drain quicker.
- Similarly, using the key fob from a longer distance can have a negative impact on battery life.

Therefore, it’s always a good idea to carry a spare battery with you, especially if you rely on your key fob extensively. It’s also important to note that some vehicles come with a backup unlocking mechanism, such as a keyhole, that can be used in case of a dead key fob battery.
In conclusion, key fob batteries typically last between 2-3 years, but this time frame can be affected by multiple factors such as usage and exposure to extreme temperatures. Keeping an eye on your key fob’s efficiency and carrying a spare battery can save you from unwanted ordeals.
