Gather Your Supplies
To ensure a smooth and successful battery replacement, gather the following supplies:
- New Battery: Check your key fob manual or the battery compartment for the correct battery type. Common types include CR2032, CR2025, and CR1620.
- Small Screwdriver: This is usually required to open the key fob’s battery compartment.
- Tweezers (Optional): Tweezers can be helpful for removing small batteries.
Locating the Battery Compartment
The battery compartment can be found in various locations on your key fob. Some common spots include:
- Behind the Key Blade: This is common for key fobs with a built-in key blade.
- On the Side: The battery compartment might be located on a side panel of the key fob.
- Under a Button: Some key fobs have a hidden compartment under a button.
Once you locate the compartment, you might need to use a small screwdriver to pry it open.
Removing the Old Battery
With the battery compartment open, you’ll see the old battery. Carefully remove the battery, taking note of its polarity (positive and negative ends). The battery might be held in place by a small spring or a clip.
Installing the New Battery
Now, it’s time to install the new battery. Ensure the new battery is correctly oriented, matching the polarity of the old battery. Gently press the battery into its compartment, ensuring it sits securely.
Closing the Battery Compartment
Close the battery compartment, ensuring it clicks shut. If you used a screwdriver to open it, use it again to close it securely.
Testing the Key Fob
After installing the new battery, test your key fob to ensure it’s working correctly. Try locking and unlocking your car doors, and if your key fob has a remote start function, test that as well.
