Below are the steps to disassemble the remote key of Changan Eado: 1. Open the key and insert a screwdriver into the key slot to pry it upward until it loosens. 2. There is a small hole at the rear end of the key; insert the screwdriver into the hole and pry upward until the cover plate loosens. 3. Then, you can directly remove the cover plate by hand. Here is a detailed introduction to car keys: 1. Currently, car keys are divided into two types: one without an anti-theft chip and the other with an anti-theft chip. 2. A remote key refers to a key that can unlock and lock the door from a distance without inserting the key into the lock. Its greatest advantage is that, regardless of day or night, there is no need to locate the lock hole, eliminating the cumbersome process of inserting the key to open the door. It allows for convenient remote unlocking (opening) and locking (closing) of the door. 3. The remote key can also open the trunk and fuel tank filler cap from outside the car, close the windows, and retract the side mirrors when locking the car.
I've disassembled the Changan Eado remote key several times, mainly because the battery died and I wanted to replace it myself. Generally, there's a seam along the edge or back of the key. You can gently pry it open with a thin plastic card or a small screwdriver. Be careful when prying—don't use too much force, or you might damage the plastic casing or the internal circuit board. Once opened, you'll see the battery slot. Note that the battery type is usually CR2032, and make sure not to insert it backward. If you're inexperienced, it's best to check video tutorials first to avoid damaging the key and having to spend hundreds on a replacement. Also, be mindful of dust getting into the circuitry—clean it thoroughly before closing the casing. Usually, disassembling the key is to save money or replace the shell, but if you really can't manage it, seek help from a professional shop. The key is to be patient—don't rush, take it slow, and prioritize safety.
I was quite nervous when disassembling my Changan Eado key myself, afraid that I might break it and have to spend extra money on repairs. First, inspect the key shell and try to find the most obvious seam point, then gently pry open a corner using a credit card or a thin tool. If it's stuck too tightly, stop and don't force it. Before replacing the battery, make sure to note the correct polarity. This kind of DIY can save some money, but if you accidentally short-circuit the circuit, the key will be completely ruined, which would be counterproductive. I recommend keeping a spare key before disassembling, so you won't panic even if something goes wrong. Additionally, the key battery typically lasts about two years, and frequent disassembly can loosen the shell, affecting its waterproofing. Nowadays, some tool kits come with specialized pry tools, which are more convenient to use.
To disassemble the Changan Eado remote key, don't panic. First, look at the back of the key where there's usually a small notch. Gently pry open the casing with a thin blade. The internal structure is simple, mainly the battery compartment—avoid touching the circuit board. After replacing the battery, test the remote range; if it's shorter, check the contacts. If it gets stuck on your first attempt, don't rush—a light tap should loosen it. There are many online guides for battery replacement—learn safely.
