Changan Oshan X7 key battery replacement steps are: 1. Pop out the metal head of the key; 2. Face the side with the enamel Volkswagen logo and a gap in the middle upwards; 3. Pinch both sides of the key and pry it upwards to split it into two halves; 4. After removing the key shell, take out the old battery and replace it with a new one. The body dimensions of the Changan Oshan X7 are: length 4705mm, width 1860mm, height 1720mm, with a wheelbase of 2780mm. The Changan Oshan X7 is equipped with a 1.5T turbocharged engine, delivering a maximum power of 131 kW, with the maximum power achieved at 5500 rpm, and the maximum torque available between 1450 to 4500 rpm.

I've been driving the Changan Oshan X7 for several years and often encounter dead key fobs. Replacing the battery yourself is simple—no need to waste money at repair shops. First, prepare a small tool like a screwdriver or a stiff card. Locate the seam on the side of the key fob and gently pry open the back cover. Don’t use too much force, as the plastic can crack easily. Inside, you’ll find a round coin-cell battery, typically a CR2032. Remember the positive and negative orientation. When removing the old battery, use your fingertips to pop it out, avoiding contact with the circuitry. Insert the new battery in the same orientation, then snap the cover back on and press firmly. Finally, test the unlock function by pressing the remote button—if the car lights flash, it’s working. These batteries are super cheap at supermarkets or online, costing just a few cents. I recommend checking the battery every six months to avoid being stranded with a locked car. If you’re not confident in your DIY skills, follow an online tutorial video for extra assurance.
Changing the key battery is a piece of cake. First, confirm the key model - the Oshan X7 uses a standard CR2032 battery. Use a small screwdriver to pry open the key along the edge, paying attention to the seam position. There's a small mark on the battery's positive side - install the new battery in the same orientation. After installation, test the remote's responsiveness; if it doesn't work, check and clean the contacts. Battery life typically lasts 1-2 years, so it's wise to keep spare batteries in your car for emergencies. Perform the replacement in a dry area to avoid static damage. DIY replacement is cost-effective, solving the problem for just a few yuan. If the key isn't working properly, take the opportunity to clean the interior as accumulated grease can affect performance. Safety first - never force components apart.
