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.
I’ve changed the battery for my Tiida key fob myself before, and it’s quite simple. You just need to prepare a CR2032 coin cell battery and find a coin or a thin tool. First, press the button on the side of the key fob to release the mechanical key, then use your fingernail or a thin tool to gently pry open the key fob along the middle seam—the top and bottom covers will separate. The old battery is usually held in a slot; carefully remove it and replace it with the new one, making sure the positive side faces up when you put it back. After installation, test whether the indicator light turns on when you press the buttons, then reassemble the casing as it was. The whole process can be done without any tools—I managed to do it in just five minutes while sitting in my car. The key is not to use excessive force when prying, as the plastic casing is quite brittle and can crack easily. Also, make sure not to insert the battery upside down to avoid damaging the circuit.
I've replaced the battery in my Tiida key fob three times now. You'll need a CR2032 battery, which is quite common to keep at home. Here's the step-by-step: Press the side button to remove the metal key, then use a coin to gently twist the key slot - the plastic casing will split in half. The small silver disc inside is the battery; carefully pry it out with a toothpick. When inserting the new battery, make sure the side with text faces up. Ensure the contacts snap firmly into place (you'll hear a click). After reassembly, test the unlock button on your car door first to avoid wasted effort. Work on a clean surface to prevent losing small parts in carpets. Note: Older model keys may require special screws, but my 2018 version uses a clip design.
