I think replacing the Peugeot 308 key battery is actually quite simple, you can do it yourself. First, when the key buttons become unresponsive, it's a signal that it's time to replace the battery. Prepare a small flat-head screwdriver, or you can use a card, and gently pry open the edge of the key casing, being careful not to use too much force to avoid damaging the clips. Once opened, you'll see a small round battery, usually a CR2025 model, note its orientation with the positive side facing up. Buy a new battery from a supermarket or online store, making sure not to get the wrong model. When installing, place the new battery in the same orientation, ensuring the positive side matches. Finally, close the casing firmly and test if the lock button is responsive. The whole process takes about 5-10 minutes, saving you money and time without needing to visit a dealership. If it still doesn't work after replacement, it might be due to improper battery installation or a hardware issue with the key that requires professional inspection. The battery typically lasts about two years, and cold weather can drain it faster, so remember to check the spare key regularly. This method is safe and efficient, and I've never had any issues doing it myself.
