Southeast DX7 key battery replacement method: 1. Remove the mechanical key and pry open the chrome decorations on both sides; 2. Split the key from the middle, remove the old battery and replace it with a new one; 3. Reassemble the key. Taking the 2020 Southeast DX7 as an example, it belongs to the compact SUV category with body dimensions of: length 4570mm, width 1905mm, height 1720mm, wheelbase 2700mm, and fuel tank capacity of 55 liters. The 2020 Southeast DX7 is equipped with a 1.5T turbocharged engine, delivering maximum horsepower of 197PS, maximum power of 145kW, maximum torque of 285Nm, paired with a 7-speed dual-clutch transmission.
As a long-time owner of the Soueast DX7, I've replaced the key fob battery several times and would like to share my experience. Find a small tool like a coin or thin plastic piece, align it with the gap on the back cover of the key fob, and gently pry it open – avoid using excessive force to prevent cracking. Inside, you'll find a round coin battery, typically CR2032, which can be easily purchased at supermarkets. Pay attention to the battery orientation; the positive side should face upwards to avoid incorrect installation. During my first attempt, I was too hasty and damaged the shell, later spending some money on a spare one – I recommend beginners prepare a spare battery in advance. If the key fob still doesn't work after replacement, it might be due to the shell clips not being securely fastened or the battery not making proper contact – test the car lock function. Regularly check the battery lifespan; it usually lasts about a year before running low, so keeping a spare battery in the car for emergencies is advisable.
As a newbie who just started driving a Southeast DX7, I recently learned how to replace the key battery when it failed. Here are some easy-to-follow steps: There's a small notch on the side of the key—use a flathead screwdriver or a business card to gently pry it open. Inside, you'll find a thin round battery. When replacing it with a new button battery, make sure to check the positive and negative marks to avoid installing it the wrong way. Before starting, ensure the car is turned off for safety. If you can't pry it open, don't force it—ask a friend for help or look up a video tutorial online for a more reliable method. After reassembling, test the key by pressing it to see if the light turns on. If there's an issue, check if the battery is installed correctly or if the contact points are dirty—clean them with a cotton swab if needed. DIY is simple and cost-effective, usually taking just 5 minutes, even for beginners. If you're unsure, it's okay to spend a little money at a shop for peace of mind.
