How to Replace the Battery in a Peugeot 408 Car Key?
2 Answers
Peugeot 408 car key battery replacement method is as follows: Remove the mechanical key and locate the hole used to remove the mechanical cover. Insert the mechanical key into the hole and gently pry open the key with your hand to open the key cover. Remove the old battery, install the new battery, close the car key cover, and finally reattach the mechanical key. Precautions for car key usage are as follows: 1. During daily use, do not place the key near high-power appliances such as televisions, microwaves, washing machines, or computers, as these appliances can reduce the battery life of the remote. 2. Do not expose the key to extremely cold environments below 0°C or extremely hot environments above 50°C, as this will significantly decrease battery life.
I often encounter dead key fob batteries with my Peugeot 408 too. Changing the battery is quite simple but requires care. First step: confirm the battery model - Peugeot 408 usually uses CR2032 coin cells, which you can buy at supermarkets or online, just make sure not to get the wrong model as it affects lifespan. Second step: use a plastic pry tool or coin to gently pry open the back cover at the middle seam - don't apply too much force or the plastic casing may crack. Third step: remove the old battery, clearly note the polarity (usually positive side up), insert the new battery ensuring proper contact alignment. Finally, snap the cover back on firmly and immediately test the remote range. I recommend keeping spare batteries in your car. Over time, the contacts may accumulate dirt - clean them when replacing the battery. The whole process takes just 2-3 minutes, saving you a trip to the dealership.
