- Slide-and-release: Some key fobs have a small slider or button on the side that you can slide or press to release the battery compartment.

- Pop-and-open: Some key fobs have a small indentation or notch that you can press to pop open the battery compartment.
Once you’ve opened the key fob, you should see the battery compartment and the old battery inside.
Step 3: Remove the Old Battery
Carefully remove the old battery from the compartment, taking note of the orientation and position of the battery terminals. You may need to use a small amount of force to dislodge the battery from its holder.
Step 4: Inspect the Old Battery (Optional)
If you have a battery tester or multimeter, you can use it to check the voltage of the old battery. This can help you determine if the battery was truly dead or if there’s another issue with your key fob.

Take the new battery and insert it into the compartment, making sure it’s properly seated and the terminals are facing the correct direction. You may need to apply a small amount of force to ensure the battery is securely in place.
Step 6: Close the Key Fob
Once the new battery is installed, close the key fob and make sure it’s securely shut. If you had to remove a screw, now is the time to replace it.
Step 7: Test the Key Fob
Try using your key fob to unlock your vehicle or start the engine. If everything is working properly, you should see the lights on your key fob flashing or the engine turning over. (See Also: Does Battery Charge When Car Is On)
