Step-by-Step Guide to Changing Your Lexus Car Key Battery
Follow these steps to replace the battery in your Lexus car key:
- Locate the battery compartment: Examine your key fob to identify the battery compartment. Lexus car keys typically have a small indentation or a slot on the back where the battery compartment is located.

- Remove the old battery: Once you have opened the key fob, you will see the battery inside. Carefully remove the old battery by gently prying it out with your fingers or using the screwdriver if necessary. Take note of the battery’s orientation; you will need to insert the new battery in the same orientation.
- Clean the key fob: Before inserting the new battery, use a clean cloth or towel to wipe away any dust or debris from the key fob’s interior. This will help ensure a proper connection between the battery and the key fob.
- Insert the new battery: Take the new battery and align it with the appropriate markings or orientation indicated inside the key fob. Push the battery firmly into place using your finger or the screwdriver. Ensure the battery is secure and properly seated within the battery compartment.
- Close the key fob: Align the two halves of the key fob, ensuring all buttons and components fit together correctly. If your key fob has a screw, use the screwdriver to tighten it back into place. If your key fob features a coin slot, simply twist it firmly until the two halves snap together.
