I'm quite familiar with replacing the battery in a Lexus remote key fob. From experience, the steps are straightforward. First, pick up the key and locate the seam on the back or side. Gently pry open the cover using a coin, small screwdriver, or your fingernail. Inside, you'll find a circular battery, typically a CR2032 model. Remove the old battery and replace it with a new genuine one, making sure the positive side faces up to avoid incorrect installation. When closing the cover, align the clips and press until you hear a click, indicating it's securely locked. Test the remote by pressing its buttons to check if the red light illuminates. If there's still no response after replacement, the key might be damaged or there could be an issue with the car's receiver—it's best to have it checked at a dealership. For maintenance, it's advisable to inspect the battery life every one or two years and avoid leaving the key in hot places like under the windshield to prevent accelerated battery aging and ensure uninterrupted use.
