How to Replace the Battery in an Infiniti Car Key?

Pull the switch on the back of the key to remove the mechanical key, then use a flathead screwdriver to pry open the smart key. Using a small flathead screwdriver can make it easier to remove the old battery. Insert the new battery, ensuring the positive terminal faces upward. Reattach the key cover and mechanical key.
A few days ago, my Infiniti car key also went on strike—running out of battery was quite a minor hiccup. I replaced the battery myself: first, locate the tiny notch on the key fob’s casing, usually along the side, and gently pry it open with a small coin or thin card. Inside lies a coin cell battery—mine was a CR2032. A new one costs just a few bucks at the supermarket. When reinstalling, ensure the positive side (usually marked with text) faces upward and snaps into place. Press the key casing firmly shut, then test the unlock button—if the green light turns on, you’re all set. I recommend keeping spare batteries at home, as they typically need replacement every two years or so. Avoid working in humid environments to prevent short circuits, and wipe your hands with a damp cloth beforehand to guard against static. The key is smartly designed, so don’t open it unnecessarily for fun. Timely replacement prevents sudden failure, ensuring safety and peace of mind.
