2 Answers
When the Nissan Tiida one-key start car key battery dies, it needs to be replaced. Below are the steps to replace the smart key battery for the Tiida: 1. First, locate a small switch on the back of the car key and flip it. 2. Pull the top part outward, and you will see the internal metal mechanical key being removed. 3. After removing the mechanical key, you will notice a small groove. 4. Use a flathead screwdriver or another tool to pry open the car key cover along the groove. Once there is a gap, you can manually open it. 5. With the key cover open, you will see a round-shaped battery inside. Remove the old battery and replace it with a new one (pay attention to the polarity). 6. Finally, reattach the key cover and insert the mechanical key back into place.
Last time I drove my Tiida for an outing, the car key suddenly stopped working. I thought the car had broken down and was sweating with anxiety. But don't worry, the Tiida is thoughtfully designed - even with a dead key battery, there's a solution. First, use the small slot on the back of the key to pop out the mechanical key blade. This often-overlooked feature slides right out when pressed and can directly unlock the driver's door. Then get in the car, hold the key close to the start button below the steering wheel, press the brake pedal and push the button - the vehicle will start right up. The battery model is a CR2032 button cell, available at convenience stores or supermarkets for very cheap. Just pry open the back cover and replace the battery yourself. It's recommended to keep a spare battery in your bag - when the remote signal weakens, that's your warning sign to replace it early and avoid embarrassment. After replacement, test all key functions to make sure everything works. Car key batteries typically last 1-2 years - regular maintenance is crucial, don't wait until it's completely dead to act.
