Insert the new battery into the key fob, making sure it is properly oriented. Press down gently to ensure that the battery is secure and in place.

Step 5: Reassemble the key fob

Carefully reassemble the key fob, making sure that all parts are correctly aligned. Press the two halves of the fob together firmly until you hear a click or feel the fob snap shut.

Step 6: Test the key fob

Once the key fob is reassembled, test it to make sure the battery replacement was successful. Try pressing the buttons to lock or unlock the car, and make sure that the range and response time are still working correctly.

In conclusion, replacing a car key fob battery is a simple and straightforward process that can be done with basic tools and a replacement battery. It is essential to determine the correct battery size and orientation and be careful not to damage the key fob when opening or reassembling it.
