I just replaced the key battery for my Peugeot 408 last month, remember to be careful. There's usually a small gap or screw on the side of the key case, gently pry it open with a small screwdriver or a hard card. Inside there's a small round battery, commonly the CR2032 model, which you can easily buy at supermarkets or online stores, not expensive. After opening the case, first observe the battery's orientation - whether the positive side faces up or down, then remove the old battery and insert the new one accordingly. When reassembling, just align the clips and press firmly. The whole process is simple, but avoid using excessive force to prevent breaking the case. A quick reminder: the battery typically lasts one to two years; replace it if the remote stops responding. Doing it yourself can save repair costs, and it's good to clean the contacts if the key has been used for a long time to prevent moisture. Keeping a spare battery at home is always wise. Give it a try, it only takes about five minutes.
As a car owner, replacing the Peugeot 408 key battery isn't as difficult as imagined. Look for the small notch or tiny screw on the key edge - I usually carefully pry it open with a bank card. Inside you'll find a CR2032 battery. Remove it while noting the positive/negative pole positions, then insert the new battery in the same orientation. Ensure good lighting during operation to avoid losing small components. After completion, test the door unlock button responsiveness. It's recommended to check every two years - don't wait until completely dead. DIY replacement saves money and time compared to shop visits, but keep a spare key just in case. If the casing feels stubborn, avoid using blades to prevent scratches. The battery costs just a few bucks. Proper key maintenance extends its overall lifespan.
