Peugeot 308 key battery replacement method is as follows: 1. Remove the mechanical key and insert it into the hole; 2. Pry open the key, remove the old battery from the key cover, and install the new battery; 3. Close the car key cover and reattach the mechanical key. The Peugeot 308 is a compact 4-door, 5-seater sedan with body dimensions of 4590mm in length, 1820mm in width, 1488mm in height, and a wheelbase of 2675mm. It is equipped with a 1.2L turbocharged engine, delivering a maximum power of 85kW at 5500rpm. The front suspension uses a MacPherson strut independent suspension, while the rear suspension employs a torsion beam non-independent suspension.

Changing the battery in a Peugeot 308 key is quite straightforward, and I usually do it myself. First, find a thin tool like a small screwdriver or coin, insert it into the gap of the key casing, and gently pry open the cover. Avoid using excessive force to prevent damaging the internal clips. Inside, you'll find a coin cell battery, model CR2032, which you can easily purchase at supermarkets or online. When removing the old battery, be careful not to dislodge any components. Then, insert the new battery with the positive side facing up. Close the casing and press the buttons a few times to check if the indicator light works. I recommend checking the battery life annually to avoid any last-minute failures. The whole process shouldn't take more than 5 minutes, and the simpler the tools, the better—no need to overcomplicate it. If you're worried about making a mistake, take a photo to record the original setup for peace of mind.

Replacing the Peugeot 308 key battery requires careful handling. Prepare anti-static gloves and a soft cloth, gently pry open the key's back cover, ensuring not to damage the internal chip. The common battery model is CR2032 - choose reputable brands when purchasing to avoid insufficient power from generic batteries. After removing the old battery, immediately insert the new one with the positive side facing up, handling gently. After replacement, close the cover and press test buttons to check responsiveness. Avoid exposing the key to high temperatures or humid environments to extend battery life. If the battery dies while out, remember to use the car's emergency start backup solution (check the manual) to prevent minor issues from becoming major problems.

Easy to operate: Carefully pry open the back cover of the key with a fine tool, remove the round battery after seeing it, and replace it with a new one (model CR2032), ensuring the positive side faces up to avoid incorrect placement. Snap the cover back on and press the button to test if the light turns on. Check the battery model when purchasing to save time.
