The method to replace the key battery for the Southeast DX7: First, remove the mechanical key, then pry open the chrome decoration of the smart key, split it from the middle, remove the old battery, and install the new battery properly. It is recommended that car owners confirm the battery model when purchasing to avoid buying unusable batteries. The Southeast DX7 is the first SUV product launched by Southeast Motors, equipped with 1.5T and 2.0T engines. The DX7 is the first model resulting from the strategic cooperation between Southeast Motors and the renowned Italian automotive design company Pininfarina. The front face of the DX7 features an eagle-wing sporty design, balancing visual appeal and aerodynamic performance. It adopts a large-area wing-shaped black matte upper and lower grille, offering a cohesive and visually striking appearance. The headlight assembly uses xenon light sources paired with LED daytime running light strips, meeting the lighting design standards for vehicles in this class.
Recently, my SouEast DX7 car key ran out of battery, and replacing it myself was quite convenient. There's usually a small latch on the back of the key fob - just press it or gently push with your fingernail to open it. If it's a bit tight, you can use a small screwdriver or coin to pry it open, but don't use too much force to avoid cracking the plastic. When removing the old battery, pay attention to the model - it's typically a CR2032 coin cell with the positive side facing up. You can buy new ones at supermarkets or auto parts stores for about 10-20 yuan. When installing the new battery, align it with the slot and make sure the '+' side faces up. After closing the case, test the remote functions by pressing the buttons - as long as they work normally, you're good. I make it a habit to replace the battery every two years to avoid sudden failure affecting my car use. The whole process is simple and takes about 5 minutes, saving both time and the extra cost of visiting a dealership. It's good practice to check your key's condition before driving to ensure safety.
As a DIY enthusiast, I find changing the DX7 key battery quite basic. There's a small gap on the side of the key casing—just gently pry it open with flat-head tweezers or a small knife. Make sure to prepare a new battery beforehand, model CR2032, and don't mix up the orientation. After opening the casing, remove the old battery, which might be a bit tight, but avoid pulling it forcefully. Before inserting the new battery, check if the contacts are clean and wipe them if necessary. When closing the casing, listen for a click to confirm it's properly secured. Test the remote unlock to ensure everything works. Avoid inserting sharp tools too deeply during the process to prevent damaging the circuitry. Common household items like toothpicks can serve as handy tools. For extra convenience, consider buying a battery kit as a spare—it costs less than 20 yuan, much cheaper than visiting a professional shop.
