The steps to replace the battery in a Peugeot 4008 key are: 1. Press the mechanical key release button on the remote key to eject the mechanical key; 2. Use a screwdriver to insert into the groove and pry open the back cover of the remote key, then remove the back cover; 3. Take out the depleted battery, install a new battery, and reattach the back cover of the remote key. The Peugeot 4008 has the following dimensions: length 4510 mm, width 1850 mm, height 1628 mm, with a wheelbase of 2730 mm, a fuel tank capacity of 53 liters, and a curb weight of 1475 kg.

I just helped my dad replace the battery in his Peugeot 4008 key a few days ago, and it was super simple. First, there's usually a small screw or clip on the back of the key—use a small screwdriver or coin to gently pry open the casing. Once opened, you'll see a small coin-cell battery, typically a CR2032 model. Be careful not to lose it. Before removing the old battery, note the positive terminal direction (usually the side marked with a '+' faces up). Next, head to a supermarket or auto parts store to buy a new CR2032 battery—don’t cheap out on off-brand ones, as quality batteries last longer. When installing the new battery, ensure the positive side faces up, align it with the slot, and press gently to secure it. Then close the casing and apply slight pressure until you hear a click, indicating it’s locked. Finally, test the key buttons to confirm they respond properly. The whole process takes just 5 minutes—much easier than expected. I recommend keeping a spare battery handy to avoid the hassle of sudden power loss. Remember to handle everything gently to avoid damaging the plastic casing.

I'm quite familiar with replacing key fob batteries because my Peugeot 4008's key often malfunctions. There's a small gap on the upper back of the key - just gently pry it open with a coin or fingernail. When removing the old battery, remember to note its model (CR2032), then buy a new one at convenience stores for just a few bucks. Install the new battery with the positive side facing up - installing it backwards won't work and wastes the battery. Simply snap the cover back on, as easy as building blocks. Before starting, unplug other electronic devices in the car just in case. The whole process takes at most 2-3 minutes, perfect for clumsy beginners like me. I've also found that if the buttons don't respond immediately, don't panic - it might just be poor contact, so try reopening and reclosing the key. After replacement, test by approaching the vehicle and pressing unlock - if the lights flash, you're good. Regularly checking battery life can prevent sudden failures.

Changing the battery for the Peugeot 4008 key is quick and easy. Pry open the key shell, use a small tool to remove the old CR2032 battery, purchase a new battery of the same model, and install it. Make sure the positive side is facing upwards, then close the shell to complete the process.
