2 Answers
To open the remote key of the Peugeot 408, insert a small screwdriver into the groove of the key and pry open the back cover of the remote. Taking the 2020 Peugeot 408 as an example, its body structure is a 4-door, 5-seater sedan with the following dimensions: length 4750mm, width 1820mm, height 1488mm, wheelbase 2730mm, fuel tank capacity 53L, and trunk capacity 455L. The 2020 Peugeot 408 is equipped with a 1.2L turbocharged engine, delivering a maximum horsepower of 136PS, maximum power of 100kW, and maximum torque of 230Nm, paired with a 6-speed dual-clutch transmission.
Opening the Peugeot 408's remote key isn't actually difficult, and I have plenty of DIY experience to share. The remote key usually consists of two parts: the plastic shell and the internal circuit board. First, find a small flathead screwdriver or thin tool and gently pry along the edge of the key. The key point for this model is on the button side, where there might be hidden clips. Be careful not to use too much force to avoid breaking the plastic. It's best to turn off the vehicle's power before disassembling to prevent short circuits. Once opened, you'll find the battery and mainboard inside. The battery is typically a CR2032, so you can check if it needs replacement. If you encounter difficulties, consulting the vehicle manual or online video tutorials can be helpful. This process might take a few minutes, so ensure safety throughout, protecting your fingers and electronic components. After completion, clean any dust before reassembling, making sure the buttons are properly reset. Remember to avoid liquid contact during disassembly to prevent corrosion. If you're unsure, don't force it to avoid damaging the key and having to spend money on a replacement. I recommend trying with a spare key or consulting a repair shop first, just in case.
