Insert the new battery with the positive side facing up. 5. Reinstall the key cover and mechanical key. 6. Operate the key to lock and unlock the car to check if the key functions properly. Here are some precautions regarding battery replacement: 1. Improper battery replacement may damage the car key. 2. Using a battery with incorrect specifications may fail to activate the key. When selecting a key battery, first check the size, and ensure the rated current and other parameters remain the same. 3. Understand the key structure beforehand, as damage caused by self-replacement of the battery is not covered under the warranty. 4. To prevent shortening the key's lifespan, avoid frequently activating related functions outside the sensing range. 5. Areas within approximately 1 meter of a magnetic field can easily cause the electronic key to malfunction. 6. Ensure hands are dry before replacement to prevent internal components from rusting.
