How to Open a Peugeot Car Key?

Flip the small switch on the key to remove the mechanical key. After pulling out the mechanical key, you will see a gap around the key casing. Use a screwdriver or other thin tool to pry it open. Turn it along the gap for a full circle to separate the smart key. Remove the old battery, replace it with a new one, then reattach the back cover and the mechanical key.
Disassembling a Peugeot car key isn't actually difficult. I enjoy doing small DIY repairs myself, like working on car keys. Usually, there's a gap on the front or side of the key where you can gently insert a small flat-head screwdriver or thin card to pry it open, but don't use too much force to avoid scratching the plastic casing. If it's a remote key, you might find a small button battery inside after prying it open, typically a CR2032 model, which can then be replaced. Before disassembling, it's best to turn off the car engine to avoid signal interference, and after disassembly, make sure to align the internal chip properly when reassembling. There's usually an instruction diagram on the label, which you can follow for a safer process. If you accidentally crack the casing, you can buy inexpensive replacement shells online, saving the hassle of going to a 4S shop. This kind of small DIY gives me a sense of accomplishment and saves some repair costs, but remember to be patient and not rush.
Last time I disassembled my Peugeot car key, I was a bit nervous since I'm a beginner. Don't worry, first confirm the key model. For my older remote key, you can slowly pry it open from the edge gap using a fingernail or thin tool. Handle gently during the process as the internal circuit components are fragile. Once opened, you'll see the battery compartment. After replacing the battery, press firmly to close it until you hear a small click to ensure proper alignment. To prevent accidents, taking a photo beforehand to remember the original position is a good idea. My experience tells me that key malfunction could be due to not just dead battery but also moisture or rust. Checking and cleaning the contacts during disassembly can improve durability. If you can't open it after several attempts, don't force it - seeking a professional is safer. This job is actually easier to learn than you might think.
