Methods to disassemble the Changan Eado key: 1. Regular key: Gently pry open the upper and lower shells of the key with a tool, replace the battery, reinsert the circuit board with the new battery into the key shell, and then press the shells together; 2. Smart key: Press the PUSH button to remove the mechanical key, use the front end of the mechanical key to pry open the key shell, replace the battery, reinsert the circuit board with the new battery into the key shell, press the shells together, and reinsert the mechanical key. The Changan Eado is a compact car under Changan Automobile. Taking the Eado 2021 PLUS Blue Whale NE1.4T GDI DCT Premium model as an example, it features a 4-door, 5-seat sedan structure with a fuel tank capacity of 53 liters, a trunk capacity of 500 liters, and a curb weight of 1340 kg. Its powertrain is equipped with a 1.4L inline 4-cylinder turbocharged engine, delivering a maximum power of 118 kW and a maximum torque of 260 Nm.
I've taken apart the Chang'an Eado key several times, and the key is to locate the seam of the back cover. Most keys have a small groove where the back cover meets the main body, which can be gently pried open with a fingernail or a flathead screwdriver. First, check the side of the key—that's usually the easiest spot to start; don't use too much force, or you might break the plastic clips. After prying open the back cover, remove the old battery and check if the contacts are dirty. If cleaning is needed, use a cotton swab dipped in alcohol to wipe them. When reassembling the back cover, simply align it and press it back into place. If the key doesn't respond or the buttons stop working, it's likely the battery is dead—replacing it with a new one should fix the issue. The whole process only takes a few minutes, but be careful to avoid damaging the internal circuitry. Before starting, it's a good idea to look up a diagram of your key model in case the structure differs.
