What does it mean when the Nissan Teana displays a key ID error?

Nissan Teana displaying a key ID error may indicate that the car key battery is dead. Vehicles have two types of starting methods: The first is the mechanical key, which is inserted into the keyhole to start the engine. The second is the smart one-button start, which starts the engine by pressing a button. Emergency starting method: When the key battery is dead or there is interference, on the right side below the steering wheel, where the old mechanical key start position is, there is an icon resembling a Wi-Fi signal. This is the emergency start signal reception position. Place the remote key close to this icon and then press the one-button start button to start the engine normally.
I have some knowledge about automotive electronic systems. When a Nissan Teana displays a 'Key ID Error,' it means the vehicle's anti-theft module cannot recognize the signal from your smart key. The most common reason is that the coin battery inside the key is dead. The battery model is usually CR2032, and you can simply buy a new one and replace it yourself. However, avoid forcing open the key casing, as it can easily damage the internal circuitry. Another possibility is an issue with the key itself, such as being dropped or exposed to water, which can damage the internal chip and prevent signal transmission. Sometimes, the problem lies with the vehicle's receiving antenna, causing poor signal reception. I recommend trying the spare key first. If the same error occurs, there might be an issue with the vehicle, and you should visit a Nissan dealership to check the NATS anti-theft system. Additionally, avoid keeping the key near your phone, as electromagnetic interference can worsen this problem. Developing a habit of regularly replacing the battery can significantly reduce the chances of this issue occurring.
