When To Change The Key Fob Battery

Step-by-Step Guide To Change The Key Fob Battery
Let’s now go over how to replace the battery in your key fob step-by-step:
1. Identify Your Key Fob Type
Different vehicles use different types of key fobs. Some may have a flip-out key, while others are compact, without any visible key.
Start by identifying the type of key fob your vehicle uses.
2. Purchase The Correct Battery
Make sure you have the right replacement battery for your particular key fob model before continuing.
To find the battery type and component number, consult your car’s owner’s handbook or get in touch with the maker.
3. Prepare Your Workspace
Choose a workspace with good lighting to ensure you can see the key fob components clearly.
Place a clean cloth or a soft surface to prevent scratches on your key fob or work surface.
4. Open The Key Fob
Depending on the make and model of your car, there are many ways to access your key fob. Here is a broad strategy:
- Examine the key fob for any visible screws or clips. If you find screws, carefully remove them using the appropriate screwdriver. If there are no screws, the key fob may be held together with plastic clips.
- To open a clip-closed key fob, gently insert a flathead screwdriver into the seam and pry it open. Be cautious not to damage the key fob or scratch the surface.
- In the case of a screw-closed key fob, remove the screws and keep them in a safe place. Then, gently pry apart the key fob’s halves.
- Remove the Old Battery
Once you have access to the inside of the key fob, locate the battery compartment. Carefully remove the old battery. Be cautious when doing this to avoid damaging any other components inside the key fob.
5. Insert The New Battery
Insert the new battery into the compartment, ensuring that it’s oriented correctly.
The positive (+) and negative (-) sides of the battery should match the markings in the compartment.
6. Close The Key Fob
Carefully align the two halves of the key fob case, ensuring all buttons and components fit together properly.
If your key fob has screws, reattach them using the screwdriver.
For clip-closed key fobs, press the halves together until you hear them click into place.
7. Test The Key Fob
Check the key fob’s operation before putting it back together completely.
Press the door locks and unlock buttons while standing close to your car.
Make sure the range is sufficient and that all of the buttons are responsive.
If everything is working as it should, your key fob battery replacement was successful.
