Tiida car key battery replacement tutorial: 1. Locate a small switch on the back of the car key and flip it. 2. Pull out the top part by gripping it firmly. 3. After removing the mechanical key, you will see a small groove. 4. Use a flathead screwdriver to pry open the car key cover along the groove. Once a gap appears, manually open it. 5. With the key cover open, remove the old battery and replace it with a new one (pay attention to the polarity). 6. Reattach the key cover and insert the mechanical key back in. How the remote key works: First, the key emits a weak radio wave, which is received by the car antenna. The electronic control unit then identifies the signal code, and the system's actuator (motor or electromagnetic coil) performs the lock/unlock action.
