How to Open a Changan Car Key?

[StPaisley]

To open a Changan car key, follow these steps: 1. Locate the trapezoidal block marked with the letters 'PUSH' on the side of the key, then press the end with the letters; 2. Pull out the silver-white strip-shaped key at the top of the key with your hand; 3. Insert the larger end of the key into the groove and twist to separate the two halves of the case. Changan's vehicle lineup includes models such as the Yuexiang, Yuexiang V3, Yuexiang V5, CX20, and CX30. Taking the 2019 Yuexiang as an example, its body dimensions are: length 4390mm, width 1725mm, height 1490mm, with a wheelbase of 2535mm, a fuel tank capacity of 40 liters, and a body structure of a 4-door, 5-seater sedan.

A while ago, I also encountered the trouble of my Changan car key not opening. After pondering for a while, I found out the battery was dead. First, find a small flat-head screwdriver, align it with the tiny gap on the side of the key, and gently pry it open—don’t use too much force, or the casing might crack. Slowly separate the shell into upper and lower halves to reveal the internal circuit board and the button battery slot. Then, use your fingernail or small tweezers to remove the old CR2032 battery, making sure to remember the orientation to avoid installing it backward. After replacing the new battery, don’t rush to reassemble it—press the button to test if the remote lights up and works. Once confirmed, snap the casing back together until you hear a click, indicating it’s secured. The whole process takes about ten minutes, but the right tools are crucial—avoid using scissors or hard objects to pry, as they can damage the key. For regular maintenance, periodically check the battery’s power consumption and avoid crushing the key with other items in your bag to extend its lifespan.

Last time I handled my Changan car key, it was quite easy to open! Usually, you can use a coin or your fingernail to pry open the gap in the key casing. Try gently pushing to separate it. Inside, you'll find a small button battery and a circuit board. Remove the old battery and replace it with a new one, making sure it's the CR2032 model—don't get the wrong one. When reassembling, align the tabs properly, and you'll hear a click when it's in place. The whole process shouldn’t take more than five minutes. Remember to wash your hands before replacing the battery to avoid oil or dirt affecting the circuit. By the way, don’t leave your car key in high-temperature places like under the windshield, as this speeds up battery aging and can cause malfunctions. Once the remote test works, you're all set. If you’re unsure, searching for a tutorial video online is a safe bet.

Opening a Changan key is actually simple. I usually use a small screwdriver to pry open the shell crack, being careful not to use excessive force. After separation, take out the battery and replace it with a new CR2032 model, then align the positions when closing it. Remember to handle it gently during the process to avoid damaging the circuit board. Finally, test the remote response to ensure everything is working properly before finishing. Avoiding dropping or rough handling of the key in daily use can prevent premature failure.

A few days ago, I repaired my Changan car key by replacing the battery. The first step is to observe the position of the shell clips, usually using a thin card to insert into the gap and pry open the upper and lower parts. Avoid using metal tools to scratch the plastic. After opening, directly replace the old battery with a new CR2032, paying attention not to reverse the polarity. Before reassembling, clean off any dust to prevent accumulation that could cause a short circuit. Using a cotton swab to wipe the circuit board during the operation is more secure, ensuring smoother key travel. The entire process takes about ten minutes, and remember to keep a spare key handy in case of operational errors. Keeping the key dry can reduce the occurrence of such issues.

When opening the Changan key, I pay special attention to safety. Use a small screwdriver to gently pry open the gap, disassemble the casing, and then remove the battery for replacement. Wear gloves throughout the process to prevent static electricity and avoid short-circuit damage to the circuit board. After installing the new battery, test the remote to ensure it works properly before reassembling. If it gets stuck, don't force it; loosen it slightly and find the right angle. After the operation, it's recommended to have a spare key as a backup, just in case the original gets damaged due to shaky hands. Taking good care of your car key can save a lot on repair costs.
