Peugeot 308 key battery replacement method is as follows: 1. Remove the key ring, use a coin to pry open the key by inserting it into the key groove and twisting; 2. Place the new battery with the positive side facing upwards into the battery slot, gently push the battery until it is fully secured. After replacing the battery, initialization is required to restore the remote control function. The Peugeot 308 is a compact sedan with dimensions of 4590mm in length, 1820mm in width, and 1488mm in height, and a wheelbase of 2675mm. In terms of safety, the vehicle offers multiple airbags, including rear side airbags and a driver's knee airbag. The entire series comes standard with ESP and a traction control system.
My Peugeot 308 has been running for almost three years, and I've replaced the key battery two or three times. Each time, I used a small screwdriver to get the job done. Locate the small groove or screw hole on the side of the key, and gently pry open the shell—don't use too much force, or the clips might break. Inside, there's a small CR2032 battery, which you can buy at the supermarket for just a couple of bucks. When replacing it, make sure to clean the metal contacts, and place the new battery with the positive side facing up—don't reverse it. Before closing the shell, press lightly to ensure it's secure. After replacing, press the key buttons a few times to test if the unlock light turns on. If everything works, you're good to go. Since the key often gets bumped in your pocket, the battery doesn't last long, so it's best to check it annually to avoid any last-minute surprises. The whole process takes less than five minutes, and doing it yourself saves a trip to the dealership.
Changing the key battery is actually quite simple, the key is the steps: First, prepare a small flat-head screwdriver and a CR2032 battery, which are easy to find on the market. Locate the opening point on the back or side of the Peugeot 308 key, usually a small slot or screw, and gently pry it open without forcing it. After opening the shell, carefully remove the old battery and clean any dust from the contacts. When installing the new battery, ensure the positive side (usually the shiny side faces up) is aligned correctly, push it in, and press firmly. Reassemble the shell until you hear a click indicating it's in place. After completion, press the key button to test if the remote function is restored. Avoid operating with electricity during the entire process to prevent short circuits and circuit damage. If you find it tricky, search for video tutorials online; many car owners have shared practical clips for reference. Remember not to buy the wrong battery model and check it regularly to prevent sudden failure when you're out.
