Key fobs are a convenient way to lock and unlock your car without having to use a key. They are also used to set off the car alarm and sometimes even start the engine. But, what happens when the battery in your key fob dies? Do you have to replace the whole key fob or can you just replace the battery? In this article, we will show you how to replace the battery in a key fob, so you don't have to spend money on a new one.
Step 1: Determine the Type of Key Fob
Before you can replace the battery in your key fob, you need to determine the type of key fob you have. There are two types of key fobs: ones with a screw and ones without a screw. If your key fob has a screw, you will need a screwdriver to open it. If your key fob doesn't have a screw, you will need a flat tool like a butter knife or a credit card to pry it open.
Step 1A: Key Fob with a Screw
If your key fob has a screw, look for the screw on the back of the key fob. Use a screwdriver to unscrew the screw and remove the back cover. Be careful not to lose the screw as you will need it to reattach the back cover.
Step 1B: Key Fob without a Screw
If your key fob doesn't have a screw, look for a small indentation on the side of the key fob. Use a flat tool like a butter knife or a credit card to pry open the key fob. Be careful not to damage the key fob as you pry it open.
Step 2: Remove the Old Battery
Once you have opened the key fob, you will see the battery. Gently remove the old battery from its slot. Be careful not to damage the key fob or the battery as you remove it.
Step 3: Replace the Battery
Take the new battery and place it in the slot where the old battery was. Make sure the positive and negative sides of the battery are facing the right way. Refer to the instructions that came with the battery if you are unsure which way the battery should be facing.
Step 4: Reattach the Back Cover
If your key fob has a screw, reattach the back cover and screw it back on. If your key fob doesn't have a screw, snap the back cover back into place.
Step 5: Test the Key Fob
Now that you have replaced the battery, it's time to test the key fob. Press the buttons on the key fob to make sure it is working properly. If the key fob is not working, check to make sure the battery is installed correctly or try replacing the battery again.
Step 6: Dispose of the Old Battery
Dispose of the old battery properly. Do not throw it in the trash as it can be harmful to the environment. Look for a battery recycling center in your area where you can dispose of the old battery safely.
Conclusion
Replacing the battery in a key fob is a simple process that can save you money in the long run. By following these steps, you can replace the battery in your key fob in just a few minutes. Remember to dispose of the old battery properly and test the key fob to make sure it is working properly.
Now that you know how to replace the battery in a key fob, you can do it yourself instead of paying someone else to do it for you. This is a great way to save money and learn a new skill. Just remember to be careful when opening the key fob and removing the old battery.
