Here is the method to replace the battery in the Changan Oshan X7 key: 1. To replace the battery in the Changan Oshan X7 key, you need to disassemble the key shell. First, pop out the metal key head. 2. Turn the side with the enamel Volkswagen logo and a gap in the middle upwards. Hold both sides of the key with your hands and gently pull upwards (with a slight tug) to separate it into two halves. 3. The upper part is the metal key head section, and the lower part is the control section. After disassembling the key shell, remove the old battery and replace it with a new one. It is not recommended for car owners to disassemble the smart key on their own, as the key contains a chip that acts as the car's ID. If damaged, you will need to provide relevant proof at a 4S store to re-pair it. Therefore, it is advised to visit a 4S store or repair shop for battery replacement or key repairs if any issues arise.
